For everyone building this in 1.14+ Fences now connect to glass. This causes the golems to be half a block higher sometimes. This can break the farm replace the glass with top slabs to fix Plss like so people see
@@ianswartz2741 Wrong in both aspects. Your translation's quality is worse than Google translate, doesn't make sense at all, additionally, the idiom does not originate from Germany, but rather from Essex, England. The idiom isn't even used in German, there is no German version of it.
What is the viability if reconstructing this farm without a perfect perimeter? I assume that the slimes actually moving might become a problem, but maybe I'm wrong.
the perfect perimeter just prevents other mobs from spawning and filling up the mob cap, the farm should still run fairly well if you light up surrounding caves with some torches
I'd love to see an update of this farm for 1.18.1. I assume the same principles apply build it down low, clear out the perimeter, etc; but hearing it with the new numbers instead of doing the math would be nice (and also I'm not sure if 9 layers is optimal anymore since we have so much more vertical real estate).
I know this is late but if you are still wondering, y=9 is the best if the first layer of your farm is y=-55 (64 block). You increase or decrease that based on where the first layer of your farm starts. Eg. if your farm started at y=-40, the most efficient layer to stop at would be y=24. This is because there are 4 spawning subchunks in a total of 64 blocks, resulting in 5.25 spawns per layer (16% more efficient).
@@dosedna4147 After doing my own testing I have found that increasing the farm from 1 subchunk to 4 subchunks does increase the efficiency by about 2 stacks per 5 minutes per farm.
Don't make the same mistake as me. Seal the pads as soon as possible. I died no less than a dozen times before all my gear despawned in the endless green sea below.
Update for 1.15 I build a double slime chunk farm using this design. It works great, but there is one slight inefficiency in the current design for 1.15, the iron golem placement. The iron golems are able to attack the slimes while they are on the edge of the platform, which can mean that the drops get stuck there and dont get collected. Therefore I propose to move the golems one block further from the platform to prevent this from happening.
@@ishaansingh2759 No I don't think so because the slimes can spot the iron golems from like 12 blocks away and since you have one on each side it will still work just as fine.
I have the exact same build that you are talking about and its not working at all and its in slime chunk. im playing on a realm if that may be the problem if u know?
@@steak_n_fries3639 Realms should not alter the vanilla game, so slimechunks should work. Have you checked the coordinates of your slimechunk? Also please check what your x and z axis is on the slimefinder, since that might be confusing. Also dont stand too close to the farm, mobs dont spawn within 24 blocks from a player.
It does work in 1.15.2 but it has some bugs now that are fixable. The golems seem to get stuck on the fence around the 2 glass blocks but if you remove the fence around the glass blocks the golems will drop onto the glass. Also the golems seem to be able to hit slimes through the fences(and some of the drops get stuck on the platform. That can be combated by moving the golem enclosure away from the slimes by one block or maybe 2. In order for that to work you may need to extend the magma platform or place one golem per layer per side.
I am running into this issue as well (in 1.18), I am going to try put a zombie behind each golem so they keep golem agro and the slimes wont get hit back onto the platform
Since i don't make mass flying machines and other moving structures, i don't need mass amounts of slime. A few tips and tricks for those who don't need to maximize: -no perimeter: -make it in a spot where you're frequently active so it's active without needing to build extra for chunk loading -no wall, no half slabs at the top, no complicated cage for the golems, just put a hole in the side of the chunk you excavated -at the bottom, put water over the magma blocks and put the slimes into a bubble elevator right into your (mass) storage/sorter. no complicated minecart pickup system is needed
This was a huge project for me during the start of the world and it was very frustrating to find out that the Minecarts keep getting stuck under the collection area. Later we noticed that ilmango's pumpkin farm never had this problem. To fix that issue with the slime farm, instead of using automatic unloading stations, we replaced it with a standard hopper clock so it would periodically collect the drops. Now it works without any issues. Build a standard hopper clock with one hopper completely filled. The time is less than 5min so no drops will despawn.
for those curious... also still working in the new 1.18 i just made from y5 to y30 and have been getting decent rates so far. did not do outside roof since i dug straight into the ground (just the chunk) so it still has the natural stone and not mining anymore after this shit lol.
This is the best tutorial and design I have seen for an underground (Y:40 and below) slime chunk farm. It is tweaked in every possible way to maximize the spawning and drops. I built this farm twice now and love it! Way more than enough slime for an entire server. Thank you for posting this and it was very informative both times. For my collection system, I use 2 minecart loops and have them run directly over 8 hoppers to deposit slime balls into many chests (never stopping to unload). I had trouble with minecarts colliding at the 90 degree turns, so I raised one track up a block at the corner and now they don't collide anymore. I will say that I had a bridge that I could not move above the edge of my slime farm and it didn't matter at all because I still get tons of slime blocks from this farm and it has only been running a week or two while I mine out a lot of blocks around it. I enjoy seeing more of the farm because it is fun to watch Slime spawn and hop over the edge. I am hoping to create a minecart AFK to utilize more vertical platforms, but that will be a lot of experimenting (which I really enjoy tinkering with).
Make a 972x972 world eater, make as much slime farms as possible, make so much slime that you can make 972 of them side by side, eat the entire Minecraft world
Kabood I feel that's how it goes with MC, the people with millions of subs are noobish and hard to watch, yet there is geniuses like this guy whom deserves alot more subs. The same could be said for alot of games or RUclips videos in general.

its the best thing in Minecraft, to create an automated world for yourself to play easier in with complicated redstone systems and farms like that. People cant actually see how interesting this game can be and think that its just a boring building game with bad graphycs...
1.16.2 and still works! just replace golems's glass platforms with top slab. since glass can be connected to fence and can lead to golems being half a block above.
Might be because his farm has no other mobs nearby whereas when we build in underground in survival, there’s a chance that there’s some caves around us which can spawn mobs. This will increase mob capacity therefore will reduce the rate of spawn of slimes
no the problem is that slimes can't spawn if other mobs are within 128x128 block radius from them, this mechanic is called shy slimes and it is the most annoying thing in the world
@The Creature 911 if you build it somewhere that mobs cant spawn in one map sized space around it either through torches or spawnproofing or just mining it all out then slimes will always be able to spawn
You should now use soul campfires instead of magma blocks because they do twice as much damage so slimes die a lot quicker and you can put hoppers under them
using soul campfires and hoppers allows you to build this farm 1 block lower, because you don't need the supporting block for the rails that the hopper minecart would normally sit on. 12 slime farms is enough to fufill mob cap and this requires 2070 hoppers. You can disable particle effects completely from specific sources with a vanilla mod.
@@Algorithm62 even with 12 slime farms server never reaches 50mspt even with 2070 hoppers, but it could be client side laggy if you don't have a mod to disable campfire smoke particles.
Absolutely perfect timing with this video: I was just about to start building a slime farm today. I had intended to just use Xisuma's design because it's powerful enough for my purposes, and I've done it enough times that it's simple for me, but it'll be fun to build a newer design that I haven't done several times before. Looking forward to loads of slime balls :)
One more question... putting transparent blocks around the farm helps with spawns, you said. But what if there are opaque blocks outside of the transparent blocks? I'm building something like this in SMP, so clearing out hundreds of blocks around the farm seems impractical. Is just having transparent blocks on the sides good enough?
I am not the right person to ask that but I know some stuff about the spawning algorithm. Now: when the game tries to spawn a mob it will check the surounding blocks at the foot hight. If the spawning attempt "hits" a solid block it will end. As far as I know it checks five blocks in each direction (at the foot level). So you dont want to have any blocks in that zone since they lower the chance of packspawning and/or (not sure about this one) normal spawning. Since some parts off the slime spawning spaces are next to the glass you shouldnt place solid blocks directly next to it. If you are digging a hole for this farm you should just expand it a bit.
For anyone who would be wondering, even without making the perimeter or AFK-ing in the most efficient position ( just above the farm at y 180 I believe from the other video) if you take the time to remove all blocks above the farm and light all the caves in the perimeter around the farm you'll still get an amazing output. So If you're playing solo or in a small group and don't have the manpower to dig the perimeter (or don't want to make an ugly hole in your world) it's still more than worth following this tutorial and at least remove the blocks above the farm (I removed everything in a 3 block radius around the slime chunk. so 22x22)
@@HoggiestHay Oddly enough, clearing out all blocks to the open sky is the most important step that kicks this farm into high output mode (that and figuring out where to stand so slimes spawn the most). It is very worth the effort of all of that material removal.
@@JKJindustries 32x32 jeez i was busy for like 4 hours doing 5x5 chunks for 4 blocks... with a beacon my slime farm is at heigt 65 wich means i removed 25600 blocks just to find a slime farm and then i need to dig out another 61440 blocks to finaly build it.... fuck me... thats gonna take like 8 hours
Instead of making the farm slightly wider to allow the large slimes to spawn, you can place trapdoors facing outwards (and opened) next to the spawn platform on the sides to make this more compact
I am confused about one thing. exactly how many blocks do I need to dig out from the edges of the platforms? Is it only to the edge of the overhang that is put on or further out?
Something that everyone should be aware of when building this design in 1.13 (maybe other versions) is that the hopper minecarts can occasionally stop or switch rails which I think is caused when the farm unloads and reloads since the rails go between chunk boundaries. Other than that, the farm works great in 1.13 and it is easy to tell that a lot of thought and research has gone into creating this design.
quick question, I found 7 slime chunks forming a "U" shape in my world. Is it more efficient to utilize all 7 chunks for the farm compared to just a farm 1 chunk in size?
Well... A U-shaped farm is fancy, but you wouldn't be able to run them all at once. Besides, this 1 chunk farm already produces so much slime in an hour, how much more could you possibly ask for?
There are more efficient methods for multiple chunks that combine, I think. This one can be built a few times but will get diminishing returns due to mob cap. The portal design he made I think works better when you have a lot of chunks because it kills the mobs faster (basically just build a nether portal every 4 blocks that covers all blocks in slime chunk, then kill the slimes as soon as they go to the nether)
@ilmango just a few questions if you don't mind clarifying. Why does a solid block at foot level two blocks outside the slime chunk border (where your glass wall is) decrease spawning? Isn't the purpose of the 18 wide platform to allow a big slime to spawn at the last spawnable block at the edge of the chunk? What is special about the glass wall that increases rates? And the second question is about the roof around the slime chunk. You didn't explain it in the first part of your video so I don't understand what that does to increase rates since it's outside of the spawn chunk? I appreciate the work! I have built a few of your designs already.
GMINUS I can't seem to find any information on this. I have heard youtubers before saying how it's bad to have solid blocks at foot level but it's never been fully explained. The roof thing confuses me too. Is it trying to force spawning attepts in surrounding chunks to somehow increase rates in the farm? It's probably all on redit... somewhere
I have the same questions. Dont know what to do with the roof- do I have to dig out everything under it? Everything over it? These are things that werent addressed since mango built in an open area
Maybe you haven't build it exactly in a slime chunk. I have built this farm yesterday and slimes spawning like hell. The basement is drowning in slime. Need to find a way to get it all out xD. Edit: Also think about the minimum distance of 24 blocks up to 128 blocks otherwise Slimes will not spawn.
Cloudwalker I know the entire thing is in a slime chunk and I rarely get any slimes, the only thing I haven't tried is digging the walls out past the chunk.
Not sure if you still read comments on this video, but I used your Minecart unloading system in another farm and it's not working. I'm positive it's set up correctly, the repeater tick speed is minimum and the comparator is not on, but the cart doesn't get close enough to the hopper to get the items in and cause the rails to turn off, so it just speeds off without dropping off it's items. This is on a realms server.
2 questions: First , you said that you should never put blocks over mobfarms. Does this account for Ironfarms, too? Lastly, you said that you wrap your farms in no opaque blocks so that the mobs can't track you. Don't they track you by eyesight through the glass? Nice video!
No they don't. Magma blocks, wither roses and campfires all do the same amount of damage. Magma blocks are cheaper than wither roses so magma blocks are the better choice. Also they don't cause lag from particles.
Absolutely great design. In case anybody was wanting to avoid minecarts, I sacrificed just the bottom layer to use magma blocks and then water sources that feed into two hoppers to avoid dealing with mine carts. (I avoid minecarts like the plague because of the freeze issue when chunks load/unload)
How exactly did you do that? I am wondering because i don't want to use minecarts aswell. So on which layer did you put the magma blocks and how do you use the water or where do you place it to collect the slime balls?
Okay Br. There may be multiple ways to go at it, but mine is essentially this: Have two rows of water sources on top of a non magma block so water flows toward the center. The “flowing” water blocks should all be be on top of magma blocks. This is what kills the bouncing slimes. Right as the water runs out of distance, place a top half slab, and blocks on top of it so slimes can’t escape. The water is capable of pushing slime balls through the bottom half slab into your next stream, which I chose to run 90 degrees to the two big water pools for simplicity. Then join these in the middle. If this isn’t clear enough let me know and I’ll try to attach a picture or something when I have more time!
I think it might have to do with capping off the spawnable area. The roof forms the highest block exposed to the sky, stopping spawn attempts above, while below it, spawn attempts go to the nearest spawnable block which is the spawn pad, giving you spawns from a wider area.
@@qwest500 I don't undestand. I thought the spawnattempts are seperate per chunk, so I wouldnt matter what is going on in the chunk next to it. And also a question: If I don't clear out the extra roof part, are all spawning attemts affected by the surrounding roof area or only those near to the edge of the chunk?
@@geiler_stecher Im not really a slime farm expert, but when i built my farm i completely dug out the chunk to bedrock and then made a slab roof like shown in the video. If you are making a smaller farm underground and dont want to dig all the way to bedrock, you dont have to. Ive seen farms work with blocks above them before, its just less efficient i think.
For PE aka bedrock beware sinking the time into this. They just rearranged where slime chunks are in 1.2.5, and I couldn't say if they plan to fix that or leave it as it is. If they don't change it back my 30 hours are down the tubes.
This is an amazing design mango! Would there be any simple way to turn this farm on/off? With slime farms it seems like the only real option is water, but that seems difficult to implement with this design. Perhaps a combination of this farm and the ones used in Scicraft's quad witch perimeter would be an effective way to get decent rates while maintaining the ability to turn it off.
there is no need to ever turn it off. just put an overflow system to dispose of excess slimeballs. the real question is how to make it work in SMP (where other players can spawn monsters in other chunks)
If you have the problem where slimes go to the very edge of magma blocks and dont get damage (next to golems in front of the 2nd fence of the 3x4 fence hold for golems) Then place a couple of slabs on each side of the fence hold (middle fence so you dont block slimes from accessing the 3rd magma block line) Cheers!
iJ0hny thanks, that worked. Also I ended up putting a 3 wide section of glass above the Golems and magma blocks at level 41, which will hopefully prevent a repeat of lightning hitting one of the Golem towers and burning it up and trashing the Golems.
If the game fails to spawn a mob due to it being on a slab like w/ that slab roof it can still end up spawning it nearby, inside the chunk. A mob spawn attempt will appear more commonly on those slabs if the blocks above are removed.
I only built the bottom layer and modified the tracks so I could use one cart because I'm really lacking resources on my friend group's new 1.11.2 server. I almost didn't have enough iron for tracks and definitely couldn't make golems, yet I'm still collecting stacks of slime with a single tier in a cave. Thanks so much for this.
Since I needed like 100 Slime Blocks to construct the flying machines that will dry my Ocean Monument, I had to build this. Now... 10 mins after bulding the Slime Farm, I already have more slime blocks than I'll ever need :P Thank you, ilmango, thank you so much for your awesome tutorials! Please, keep up the great work! :)
Since bedrock is on layer 5 the rails have to sit on top of that, so the magma block has to be at layer 7. If I start at layer 7 do I stop at 28 or can I go to 31?
F3 gives foot level, not eye level. From wiki "To clarify: When the display shows you are at Y=63, then the player's feet are at Y=63, the player's legs are approximately 63.5 and the player's eyes are at 64.62". You have to look at the block and check "Looking at" line on the F3. He is clearly looking at block with y = 6 at the lowest spawn platform
Will a roof at ~Y=60 decrease the spawning rate because this subchunk would be checked for spawning? Side note: I want to build the farm on a multiplayer server
The algorithm checks every block up to the highest block in the chunk, so even if you use a glass roof it will lower the rates. Don’t put any blocks above the top spawning floor for max efficiency
Didn't see a comment about this... press f3 + b at the same time to see the sight lines of all entities (preferably the iron golems) and it also allows items to be seen easier, because they light up with a white unmissable gleam...
Now, you see, I *could* clear out the whole chunk, but I'm making a slime farm to cover two people. We don't *need* 18200 slimeballs/hour. 5500/hour seems fine to me. And hey, I can always clear out the rest of the chunk later.
Hi ilmango, I’ve heard that in newer versions the sub chunk rules are replaced by the highest block rules. What should this means to the numbers of spawning platforms? Btw, if I do not have a perimeter, is it better to have platforms all the way up to y40? Thanks!
I built this in 1.14 but for some reason, the iron golems attack the slimes. This makes it so that the slimes die on the platforms themselves (on all levels), so it's less efficient. I don't see that happening in the video, so could it be something related to the newer version, or?
Hey! Im trying to build this farm and i have a question: is it necesary to dig everything under the slabs outside de slime chunck? (Is it necesay to dig a perimeter bigger then the slime chunk itself i mean?)
I'm not entirely sure if this causes a problem, but in the video, fences do not connect to glass. They do in the version that I am building this on (1.4.4) and it makes the iron golems stand slightly higher, which could potentially mess with the farm due to their eye levels being higher. People are saying the farm still works on 1.4.4+ so this fix is likely not necessary, but for all golems above the first level I used glass panes instead of glass blocks, as they function the same but do not allow fences to connect, therefore maintaining the eye level used in the video.
Just tested in 1.15 and still works fine, for me around 2.5k/h. Yes... It's ''LOW'' because I just lit up caves around cus I'm not insane enough to make a perimiter xD Also for my singe player world it's a lifetime supply after one night afk xD Edit: I also have an ocean above so I'm not even messing with it.... It's good enough xD
@@craftgames1882 I made my spawning platforms spot on in slime chunks, no slimes beyond the platform can spawn for me. Also I forgot to mention mine is a double chunk, 16x32
I built this in single player. I did not build it in a quarry, though. It works phenomenally. Lighting up caves sucked, but the rates are great. I am a n00b that has no idea where to afk for the best rates. I now have enough slime for anything. Great build and great science ilmango.
BIG SIDE NOTE... If you want your collection system to keep working the Glass wall on the side IS NECESSARY. Slimes will ocasionally go off the sides and trample your minecarts.
I downloaded the 16000 version and it was working fine, but when I built the exact version, it's nowhere as efficient as the world downloaded. I've tried lighting up the caves but it didnt effect it, any fixes? Edit: I'm on 1.14.4
paco castañeda That’s the Fox I did and now it works just as efficient also stand about 35 blocks away from your closest layer so for me I stay at around 75 y level
Not yet. I was planning on making one with your TNT-flying machine method. I didn't watch the tutorial part yet, so sorry if you said this on it. How big would the perimeter be and where would it have to be centered?
you can find everything you need to known in the first half of this video: ruclips.net/video/Fph7kUDT_zs/видео.html You don't need a full perimeter for a slime farm. As long as no other mob can spawn within 128 blocks of your AFK spot, you get the best rates. Figure it out
I like to use water streams over the magma blocks to funnel all the slime balls to a hopper. You don't have to worry about fixing the minecarts if they get stuck due to chunk loading, and it requires a lot less resources.
If you want to improve the rates of your farm, yes. But also, to min-max the rates, the ideal would be to dig out a perimeter, so nothing could spawn anywhere near your farm. The core of slime farms is to dig the the area of the slime chunk, build up the spawn platforms, do something to kill the slimes, like the iron golens, and a colection system. Anything further than that is good to improve the rates, but not really necessary. It's up to how much are you willing to dig :)
@@Oswary ok cool thanks for the reply :) i put the platforms and golems in place and am getting some slime at least. Probably enough for now. And I guess I can work on some quarrying machines later if I need to make a perimeter to improve yields :)
Anywhere in medium proximity to the chunk the farm is in, so the chunk is loaded. Your view distance is the furthest you can stand away from the farm, I believe. You will want to stand somewhere you load the fewest unlit caves, to prevent the mob cap from interfering with the slime spawning.
M4RK3T I'm pretty sure somewhere between 24 blocks away and 128 blocks away, mobs don't spawn in a 24 block radius from players, and they instantly despawn more than 128 blocks away
Thanks ilmango. I built this in Pocket Edition 1.2 lining from level 40 down with glass and a half slab walkway outside it as I dug. I lit up the caves within 125 or so, and the surface, but skipped the outer 7 wide rim. Even with just that, I am getting a full double chest on each Minecart Track every 60 minutes or so which is plenty for me. In Pocket Edition the Golems were taking damage from the magma on the bottom layer, but adding a half slab to that Golems pedestal has worked. PS cussed lava lake.
Ilmango. Always doing the best tutorials for the best farms. If only people that came for them would subscribe... Also: In more recent videos, the best intro as well...
This farm and video have too many unanswered questions: 1) Where is the best place for player to be to have farm active 2) woith high spawn rates does this not fill the mob cap (killing any other farms) so why is there no mechanism to switch it off? 3) do all the surrounding blocks need to be removed or is lighting caves sufficient (best to say so). And I see comments from people saying it no longer works (and slimes cannot spawn on slabs!)!??
1) depends. check the wiki how mob spawning works. usually you want to be at least 24 blocks away from spawning spaces of your farm and have the least amount of spawning spaces outside of the farm within a 128 block range. you see there are a lot of variables. 2) no space for a turn off mechanism. It#s possible to make one, but you need to sacrifice spawning spaces. We showed it in our last server tour how you can implement it. 3) there's a world download. if you have any doubt that something doesn't work check for yourself. usually I don't have the time to answer questions like if mobs can spawn on slabs (yes, they can).
I built this in 1.13.2 on realms and I don't get that many spawns... At what Y should I afk? Right now I am afking in a glass box, around 20 blocks above the farm. Help me, please
The game can check for a mob spawning attempt anywhere, if it ends up failing due to being on a slab then it will try a nearby location, which has a chance to be inside the slime chunk. Having blocks around it at the top makes sure that if that happens anywhere in the surrounding regions it can jump that spawn into the chunk, i think? I'm not sure exactly but the idea is that it redirects a portion of nearby failed spawns into successful slime spawns.
Hey just grabbing this message to ask a question ilmango. Could i raise the farm by 1 block? Would give me more space at the bottom. Because atm the farm is up to y 30 and not y 31. Does that effect the rates? Thanks for the great design!
Water is a transparent block but with partial opacity. So it reduced light by 2 levels each block but still counts as a transparent block. So, the question is more like, does transparent blocks above the farm affect the spawn rate? If we had glass above it, will it affect sub-chunks spawn height? And, while at it, why the ceiling around the slime chunk? You never explained why its required and how it affects the spawn rate!
I dont think you are going to read this anymore, but I hope you do. the slabs around the farm at the top are for making the game start with the spawning algorithm in the space around the farm as well. As some earlier comments said, the spawning algoritm will chose a block to start. from there it can go 5 blocks in each direction (or a 5x5 square with in the centre the initial block. I am not sure wich one, but since the slab roof is 7 blocks wide, it is more likely to be 5 blocks in each direction). So the game will try in that area to spawn in some mobs (I think it will try to spawn 3 different sorts mobs with 4 mobs per sort, with in total 4 mobs) if the algoritm started outside the farm, but it tried to spawn slimes (it can not spawn them outside since it is not in a slimechunk, but inside the farm it can spawn there) some of the area where it starts to spawn can fall within the farm. the slabs are needed to make sure the games try to spawn mobs in that place as well. As you probably know, if you remove all the blocks above a mob farm, and the farm is in a low y-level, mobs spawn faster, because the game only has to try spawning in a smaller area. if the slabs were not there, the complete subchunk and all the subchunks above would be air and the game would not try to start the algoritm there, resulting in not getting spawns that started in the outside.
I realize I’m a bit late to the party but... could you build a spire of glass outside of the slime chunk and the roof marked out without affecting rates?
One way you could make the farm slightly more efficient is by extending the rails past the 18 blocks, because when rails curve, they don't pick up items on the corners.
This is pretty much the first thing that came to my mind when magma blocks were introduced :D it didn't occur to me to use iron golems to attract the slimes though, and consequently I just had the traditional four-side drop with hopper-minecarts running along each horizontal line, which wasted a lot of gold - off to make a few changes!
For everyone building this in 1.14+
Fences now connect to glass. This causes the golems to be half a block higher sometimes. This can break the farm replace the glass with top slabs to fix
Plss like so people see
Also take a look at the unloading system and maybe make it to be one rail line instead of two because minecarts may glitch over
Mobs still spawn on top slabs dont they though?
@@galaxydimensions6057 yes they do. I replaced the fences that connect to glass with glass blocks works fine

I'd love to see an update of this farm for 1.18.1. I assume the same principles apply build it down low, clear out the perimeter, etc; but hearing it with the new numbers instead of doing the math would be nice (and also I'm not sure if 9 layers is optimal anymore since we have so much more vertical real estate).
I know this is late but if you are still wondering, y=9 is the best if the first layer of your farm is y=-55 (64 block). You increase or decrease that based on where the first layer of your farm starts. Eg. if your farm started at y=-40, the most efficient layer to stop at would be y=24. This is because there are 4 spawning subchunks in a total of 64 blocks, resulting in 5.25 spawns per layer (16% more efficient).

Update for 1.15
I build a double slime chunk farm using this design. It works great, but there is one slight inefficiency in the current design for 1.15, the iron golem placement. The iron golems are able to attack the slimes while they are on the edge of the platform, which can mean that the drops get stuck there and dont get collected. Therefore I propose to move the golems one block further from the platform to prevent this from happening.
MeAkelake will that impact the slimes noticing the iron golems?
@@ishaansingh2759 No I don't think so because the slimes can spot the iron golems from like 12 blocks away and since you have one on each side it will still work just as fine.
Sander v alright thanks
I have the exact same build that you are talking about and its not working at all and its in slime chunk. im playing on a realm if that may be the problem if u know?
@@steak_n_fries3639 Realms should not alter the vanilla game, so slimechunks should work. Have you checked the coordinates of your slimechunk? Also please check what your x and z axis is on the slimefinder, since that might be confusing. Also dont stand too close to the farm, mobs dont spawn within 24 blocks from a player.
It does work in 1.15.2 but it has some bugs now that are fixable. The golems seem to get stuck on the fence around the 2 glass blocks but if you remove the fence around the glass blocks the golems will drop onto the glass. Also the golems seem to be able to hit slimes through the fences(and some of the drops get stuck on the platform. That can be combated by moving the golem enclosure away from the slimes by one block or maybe 2. In order for that to work you may need to extend the magma platform or place one golem per layer per side.
Can you still use slabs?
@@StarfleetRei No reason not to use them
I am running into this issue as well (in 1.18), I am going to try put a zombie behind each golem so they keep golem agro and the slimes wont get hit back onto the platform
Since i don't make mass flying machines and other moving structures, i don't need mass amounts of slime. A few tips and tricks for those who don't need to maximize:
-no perimeter: -make it in a spot where you're frequently active so it's active without needing to build extra for chunk loading
-no wall, no half slabs at the top, no complicated cage for the golems, just put a hole in the side of the chunk you excavated
-at the bottom, put water over the magma blocks and put the slimes into a bubble elevator right into your (mass) storage/sorter. no complicated minecart pickup system is needed
so do i have golems in it still? or do you mean you got rid of golems completely
@@Greesher Golems are necessary to attract the slimes to the centre killing chamber
This was a huge project for me during the start of the world and it was very frustrating to find out that the Minecarts keep getting stuck under the collection area. Later we noticed that ilmango's pumpkin farm never had this problem. To fix that issue with the slime farm, instead of using automatic unloading stations, we replaced it with a standard hopper clock so it would periodically collect the drops. Now it works without any issues. Build a standard hopper clock with one hopper completely filled. The time is less than 5min so no drops will despawn.
Rohan Tej thanks a lot buddy
I am currently having this problem. Ill try this and see if it works
What would be a good place to afk for the farm to use all available spots
for those curious... also still working in the new 1.18
i just made from y5 to y30 and have been getting decent rates so far. did not do outside roof since i dug straight into the ground (just the chunk) so it still has the natural stone and not mining anymore after this shit lol.
This is the best tutorial and design I have seen for an underground (Y:40 and below) slime chunk farm. It is tweaked in every possible way to maximize the spawning and drops. I built this farm twice now and love it! Way more than enough slime for an entire server. Thank you for posting this and it was very informative both times. For my collection system, I use 2 minecart loops and have them run directly over 8 hoppers to deposit slime balls into many chests (never stopping to unload). I had trouble with minecarts colliding at the 90 degree turns, so I raised one track up a block at the corner and now they don't collide anymore. I will say that I had a bridge that I could not move above the edge of my slime farm and it didn't matter at all because I still get tons of slime blocks from this farm and it has only been running a week or two while I mine out a lot of blocks around it. I enjoy seeing more of the farm because it is fun to watch Slime spawn and hop over the edge. I am hoping to create a minecart AFK to utilize more vertical platforms, but that will be a lot of experimenting (which I really enjoy tinkering with).

Might be because his farm has no other mobs nearby whereas when we build in underground in survival, there’s a chance that there’s some caves around us which can spawn mobs. This will increase mob capacity therefore will reduce the rate of spawn of slimes
no the problem is that slimes can't spawn if other mobs are within 128x128 block radius from them, this mechanic is called shy slimes and it is the most annoying thing in the world
@The Creature 911 if you build it somewhere that mobs cant spawn in one map sized space around it either through torches or spawnproofing or just mining it all out then slimes will always be able to spawn
You should now use soul campfires instead of magma blocks because they do twice as much damage so slimes die a lot quicker and you can put hoppers under them
a lot laggy too
using soul campfires and hoppers allows you to build this farm 1 block lower, because you don't need the supporting block for the rails that the hopper minecart would normally sit on. 12 slime farms is enough to fufill mob cap and this requires 2070 hoppers. You can disable particle effects completely from specific sources with a vanilla mod.
@@Algorithm62 even with 12 slime farms server never reaches 50mspt even with 2070 hoppers, but it could be client side laggy if you don't have a mod to disable campfire smoke particles.
Illmango: oh wait guy i forgot to say that you have to remove any terrain around the farm
Absolutely perfect timing with this video: I was just about to start building a slime farm today. I had intended to just use Xisuma's design because it's powerful enough for my purposes, and I've done it enough times that it's simple for me, but it'll be fun to build a newer design that I haven't done several times before. Looking forward to loads of slime balls :)
Fantastic pls make more is this a series because you made the witch farm too with this and how many double chest is that ?
I think it is about 5 double chests, it's huge !
One more question... putting transparent blocks around the farm helps with spawns, you said. But what if there are opaque blocks outside of the transparent blocks? I'm building something like this in SMP, so clearing out hundreds of blocks around the farm seems impractical. Is just having transparent blocks on the sides good enough?
You can have solid blocks around the glass. The glass is to allow slimes to spawn on the edge block so the blocks outside of that do not matter.
You cant just put bocks around the glass, you would lower the rate of pack spawning
I am not the right person to ask that but I know some stuff about the spawning algorithm.
Now: when the game tries to spawn a mob it will check the surounding blocks at the foot hight. If the spawning attempt "hits" a solid block it will end.
As far as I know it checks five blocks in each direction (at the foot level). So you dont want to have any blocks in that zone since they lower the chance of packspawning and/or (not sure about this one) normal spawning.
Since some parts off the slime spawning spaces are next to the glass you shouldnt place solid blocks directly next to it. If you are digging a hole for this farm you should just expand it a bit.
For anyone who would be wondering, even without making the perimeter or AFK-ing in the most efficient position ( just above the farm at y 180 I believe from the other video) if you take the time to remove all blocks above the farm and light all the caves in the perimeter around the farm you'll still get an amazing output.
So If you're playing solo or in a small group and don't have the manpower to dig the perimeter (or don't want to make an ugly hole in your world) it's still more than worth following this tutorial and at least remove the blocks above the farm (I removed everything in a 3 block radius around the slime chunk. so 22x22)
Sorry, just to be clear... Do you mean all the blocks up to surface?
@@HoggiestHay yes exactly, nothing between the highest platform and the sky
@@JezaGaia hahahaha that's not happening. Thanks tho!

I remember building my 1st slime farm. Cant wait to upgrade it to this.
Something that everyone should be aware of when building this design in 1.13 (maybe other versions) is that the hopper minecarts can occasionally stop or switch rails which I think is caused when the farm unloads and reloads since the rails go between chunk boundaries. Other than that, the farm works great in 1.13 and it is easy to tell that a lot of thought and research has gone into creating this design.
orinahari8373 mentioned that you can use hoppers in place of the rails and replace the magma with soul campfires to fix this
quick question, I found 7 slime chunks forming a "U" shape in my world. Is it more efficient to utilize all 7 chunks for the farm compared to just a farm 1 chunk in size?
Well... A U-shaped farm is fancy, but you wouldn't be able to run them all at once. Besides, this 1 chunk farm already produces so much slime in an hour, how much more could you possibly ask for?
@@mirady9675 all of the slime
There are more efficient methods for multiple chunks that combine, I think. This one can be built a few times but will get diminishing returns due to mob cap. The portal design he made I think works better when you have a lot of chunks because it kills the mobs faster (basically just build a nether portal every 4 blocks that covers all blocks in slime chunk, then kill the slimes as soon as they go to the nether)
Since you mentioned leaves, I guess you could replace the non-spawning slabs AND the glass with leaves, to make it cheaper.
does it work in 1.16 i guess it works?
Yes with a simple change. The glass that iron golems spawn on needs to be top slabs instead of glass.
@ilmango just a few questions if you don't mind clarifying.
Why does a solid block at foot level two blocks outside the slime chunk border (where your glass wall is) decrease spawning? Isn't the purpose of the 18 wide platform to allow a big slime to spawn at the last spawnable block at the edge of the chunk? What is special about the glass wall that increases rates?
And the second question is about the roof around the slime chunk. You didn't explain it in the first part of your video so I don't understand what that does to increase rates since it's outside of the spawn chunk?
I appreciate the work! I have built a few of your designs already.
GMINUS I can't seem to find any information on this. I have heard youtubers before saying how it's bad to have solid blocks at foot level but it's never been fully explained. The roof thing confuses me too. Is it trying to force spawning attepts in surrounding chunks to somehow increase rates in the farm? It's probably all on redit... somewhere
I have the same questions. Dont know what to do with the roof- do I have to dig out everything under it? Everything over it? These are things that werent addressed since mango built in an open area
I hope this gets answered.
I've built this whole farm and hardly any slimes are spawning.
Maybe you haven't build it exactly in a slime chunk. I have built this farm yesterday and slimes spawning like hell. The basement is drowning in slime. Need to find a way to get it all out xD.
Edit: Also think about the minimum distance of 24 blocks up to 128 blocks otherwise Slimes will not spawn.
Cloudwalker I know the entire thing is in a slime chunk and I rarely get any slimes, the only thing I haven't tried is digging the walls out past the chunk.
Thanks for the info on sub chunks man! I knew my farm could’ve been more efficient. You’re the man!
Not sure if you still read comments on this video, but I used your Minecart unloading system in another farm and it's not working. I'm positive it's set up correctly, the repeater tick speed is minimum and the comparator is not on, but the cart doesn't get close enough to the hopper to get the items in and cause the rails to turn off, so it just speeds off without dropping off it's items. This is on a realms server.
2 questions: First , you said that you should never put blocks over mobfarms. Does this account for Ironfarms, too? Lastly, you said that you wrap your farms in no opaque blocks so that the mobs can't track you. Don't they track you by eyesight through the glass? Nice video!
no, I meant hostile/passive/water mob farms. I'm quite certain they can't track you through full blocks,
Would it be possible to use snow golems instead of iron? If you can compensate for the height difference it would be much cheaper.
Still working on 1.17 everyone
Does it work on 1.17.1
@@omidnuri2938 yeah man
This farm can be little more efficient if you use wither roses instead of magma blocks since it kills the slimes faster freeing the mob cap.
No they don't. Magma blocks, wither roses and campfires all do the same amount of damage. Magma blocks are cheaper than wither roses so magma blocks are the better choice. Also they don't cause lag from particles.
Absolutely great design. In case anybody was wanting to avoid minecarts, I sacrificed just the bottom layer to use magma blocks and then water sources that feed into two hoppers to avoid dealing with mine carts. (I avoid minecarts like the plague because of the freeze issue when chunks load/unload)
How exactly did you do that? I am wondering because i don't want to use minecarts aswell. So on which layer did you put the magma blocks and how do you use the water or where do you place it to collect the slime balls?
Okay Br.
There may be multiple ways to go at it, but mine is essentially this:
Have two rows of water sources on top of a non magma block so water flows toward the center.
The “flowing” water blocks should all be be on top of magma blocks. This is what kills the bouncing slimes. Right as the water runs out of distance, place a top half slab, and blocks on top of it so slimes can’t escape. The water is capable of pushing slime balls through the bottom half slab into your next stream, which I chose to run 90 degrees to the two big water pools for simplicity. Then join these in the middle.
If this isn’t clear enough let me know and I’ll try to attach a picture or something when I have more time!
StirInspiration Thanks for the explanation! And yes, I think a photo or even a short video would greatly help (:
I've watched video a few times was there an explanation for the extra roof?
I think it might have to do with capping off the spawnable area. The roof forms the highest block exposed to the sky, stopping spawn attempts above, while below it, spawn attempts go to the nearest spawnable block which is the spawn pad, giving you spawns from a wider area.
Yeah the roof improves efficiency a lot by disallowing spawn attempts.
@@qwest500 I don't undestand. I thought the spawnattempts are seperate per chunk, so I wouldnt matter what is going on in the chunk next to it.

@@geiler_stecher Im not really a slime farm expert, but when i built my farm i completely dug out the chunk to bedrock and then made a slab roof like shown in the video.

Elena SSF try two weeks of work down the drain :(
This is an amazing design mango! Would there be any simple way to turn this farm on/off? With slime farms it seems like the only real option is water, but that seems difficult to implement with this design. Perhaps a combination of this farm and the ones used in Scicraft's quad witch perimeter would be an effective way to get decent rates while maintaining the ability to turn it off.
there is no need to ever turn it off. just put an overflow system to dispose of excess slimeballs. the real question is how to make it work in SMP (where other players can spawn monsters in other chunks)
You have to be 24 block away
Built this in 1.17.1 today. Holy slimeballs!!! Works great! Thanks for the tutorial!
At 8:39, the 4 glass blocks are on the inside corners of the slime chunk right?
He starts to build on 8:38 if your wondering. Start at Y=30 down to Y=6.
why my minecarts are getting stuck always and going on another railway..
If you have the problem where slimes go to the very edge of magma blocks and dont get damage (next to golems in front of the 2nd fence of the 3x4 fence hold for golems) Then place a couple of slabs on each side of the fence hold (middle fence so you dont block slimes from accessing the 3rd magma block line) Cheers!
iJ0hny thanks, that worked. Also I ended up putting a 3 wide section of glass above the Golems and magma blocks at level 41, which will hopefully prevent a repeat of lightning hitting one of the Golem towers and burning it up and trashing the Golems.
how far do I have to light the caves ?
At 7:17 why do you recommend clearing the extended roof area above the chunk and not just the 16x16 chunk footprint?
cause of how spawning is calculated it checks area outside of the chunk as well for spawning attempts
If the game fails to spawn a mob due to it being on a slab like w/ that slab roof it can still end up spawning it nearby, inside the chunk. A mob spawn attempt will appear more commonly on those slabs if the blocks above are removed.
I only built the bottom layer and modified the tracks so I could use one cart because I'm really lacking resources on my friend group's new 1.11.2 server. I almost didn't have enough iron for tracks and definitely couldn't make golems, yet I'm still collecting stacks of slime with a single tier in a cave. Thanks so much for this.

Pianoman 75,500 per hour sounds good. Good luck mining the chunks.
Anyone with the same question should check out his 2x2 slime chunk video. It has an explanation of a 1x6 farm at the end. Link in the description.
Since bedrock is on layer 5 the rails have to sit on top of that, so the magma block has to be at layer 7. If I start at layer 7 do I stop at 28 or can I go to 31?
Bedrock is on layer 4, rails on 5, magma block on 6. F3 gives eye level, not foot level.
F3 gives foot level, not eye level. From wiki "To clarify: When the display shows you are at Y=63, then the player's feet are at Y=63, the player's legs are approximately 63.5 and the player's eyes are at 64.62". You have to look at the block and check "Looking at" line on the F3. He is clearly looking at block with y = 6 at the lowest spawn platform
Will a roof at ~Y=60 decrease the spawning rate because this subchunk would be checked for spawning? Side note: I want to build the farm on a multiplayer server
Kenne if you wanted to put a roof at all make them transparent blocks, and slimes only spawn y=40 and lower
The algorithm checks every block up to the highest block in the chunk, so even if you use a glass roof it will lower the rates. Don’t put any blocks above the top spawning floor for max efficiency

Now, you see, I *could* clear out the whole chunk, but I'm making a slime farm to cover two people. We don't *need* 18200 slimeballs/hour. 5500/hour seems fine to me.
And hey, I can always clear out the rest of the chunk later.
I am building 4 for solo use :(
Hi ilmango, I’ve heard that in newer versions the sub chunk rules are replaced by the highest block rules. What should this means to the numbers of spawning platforms? Btw, if I do not have a perimeter, is it better to have platforms all the way up to y40? Thanks!
Someone in the comments said that 4 subchunks is the best, I tested it myself and it is indeed about 10%-16% faster with 4 subchunks instead of 1
I built this in 1.14 but for some reason, the iron golems attack the slimes. This makes it so that the slimes die on the platforms themselves (on all levels), so it's less efficient. I don't see that happening in the video, so could it be something related to the newer version, or?

Hey! Im trying to build this farm and i have a question: is it necesary to dig everything under the slabs outside de slime chunck? (Is it necesay to dig a perimeter bigger then the slime chunk itself i mean?)
no, but its more efficient that way
@@matejbostjancic6223 ok thk, time to dig i guess
I'm not entirely sure if this causes a problem, but in the video, fences do not connect to glass. They do in the version that I am building this on (1.4.4) and it makes the iron golems stand slightly higher, which could potentially mess with the farm due to their eye levels being higher. People are saying the farm still works on 1.4.4+ so this fix is likely not necessary, but for all golems above the first level I used glass panes instead of glass blocks, as they function the same but do not allow fences to connect, therefore maintaining the eye level used in the video.
I've been working on this farm for so long I dont even remember the original project I was going to build that required slime blocks. *sigh*
Is it more efficient in 1.13/1.14+ to use less layers due to the subchunk spawning rule being removed?
i dont think sub chunks were removed?
@@D0G5Coolpat11 I'm pretty sure it's now block by block instead of chunk by chunk, which means it might be more effective to just have one layer.
Just tested in 1.15 and still works fine, for me around 2.5k/h. Yes... It's ''LOW'' because I just lit up caves around cus I'm not insane enough to make a perimiter xD Also for my singe player world it's a lifetime supply after one night afk xD
Edit: I also have an ocean above so I'm not even messing with it.... It's good enough xD
thanks
try use sponges to clean up the ocean lol
do you also have the problem that there are slimes spawning on top of the slabs around the farm? bc i have that
@@craftgames1882 I made my spawning platforms spot on in slime chunks, no slimes beyond the platform can spawn for me. Also I forgot to mention mine is a double chunk, 16x32
dumb question maybe, but where do you afk?
I built this in single player. I did not build it in a quarry, though. It works phenomenally. Lighting up caves sucked, but the rates are great. I am a n00b that has no idea where to afk for the best rates. I now have enough slime for anything. Great build and great science ilmango.
BIG SIDE NOTE... If you want your collection system to keep working the Glass wall on the side IS NECESSARY. Slimes will ocasionally go off the sides and trample your minecarts.
I downloaded the 16000 version and it was working fine, but when I built the exact version, it's nowhere as efficient as the world downloaded. I've tried lighting up the caves but it didnt effect it, any fixes?
Edit: I'm on 1.14.4
Ryder Wang You need to build it in a slime chunk
@@Anon-xz7sg He did. he just said it isn't as efficient.
I was having the same problem, put your render distance to 2 chunks
@@Koopzter does that really work?
paco castañeda That’s the Fox I did and now it works just as efficient also stand about 35 blocks away from your closest layer so for me I stay at around 75 y level
is it possible to build this if I have 4 slime chunks next to each other ? (i mean square)
Yep just build 2 more collection arreas in the opposite direction to the other ones and pus golems on those direction too,idk if you understood.
What would you recommend doing if I have a 2x2 of slime chunks? Also, would having that improve the rates?
depends. without additional information I can't give advice. do you have a perimeter?
Not yet. I was planning on making one with your TNT-flying machine method. I didn't watch the tutorial part yet, so sorry if you said this on it. How big would the perimeter be and where would it have to be centered?
you can find everything you need to known in the first half of this video: ruclips.net/video/Fph7kUDT_zs/видео.html
You don't need a full perimeter for a slime farm. As long as no other mob can spawn within 128 blocks of your AFK spot, you get the best rates. Figure it out
4:10 is not faster use maxEntityCraming???? (just asking)
1:25 and what happen with the torchs? the spawn dont decrease for them??? (just asking again)
Ugh, I've been waiting FOREVER for this one. Thanks.
I like to use water streams over the magma blocks to funnel all the slime balls to a hopper. You don't have to worry about fixing the minecarts if they get stuck due to chunk loading, and it requires a lot less resources.
Only a german can be this efficient about a game...
M W how do u know he’s German?
@@logiic8835 its obvious by his accent.
M W ok thanks!
@@logiic8835 you could also see that his language in windows was set to german in one video
4:43 Do I need to mine out all the blocks *below* the roof (that goes around the chunk) too? I'm new to mob farms. Thanks :)
If you want to improve the rates of your farm, yes. But also, to min-max the rates, the ideal would be to dig out a perimeter, so nothing could spawn anywhere near your farm. The core of slime farms is to dig the the area of the slime chunk, build up the spawn platforms, do something to kill the slimes, like the iron golens, and a colection system. Anything further than that is good to improve the rates, but not really necessary. It's up to how much are you willing to dig :)
@@Oswary ok cool thanks for the reply :) i put the platforms and golems in place and am getting some slime at least. Probably enough for now. And I guess I can work on some quarrying machines later if I need to make a perimeter to improve yields :)
where do you afk when using this farm?
Anywhere in medium proximity to the chunk the farm is in, so the chunk is loaded. Your view distance is the furthest you can stand away from the farm, I believe. You will want to stand somewhere you load the fewest unlit caves, to prevent the mob cap from interfering with the slime spawning.
M4RK3T I'm pretty sure somewhere between 24 blocks away and 128 blocks away, mobs don't spawn in a 24 block radius from players, and they instantly despawn more than 128 blocks away
third grade must be tough for you, huh?
How much space is there between each spawning platform?
2 blocks or 3?
Thanks ilmango. I built this in Pocket Edition 1.2 lining from level 40 down with glass and a half slab walkway outside it as I dug. I lit up the caves within 125 or so, and the surface, but skipped the outer 7 wide rim. Even with just that, I am getting a full double chest on each Minecart Track every 60 minutes or so which is plenty for me. In Pocket Edition the Golems were taking damage from the magma on the bottom layer, but adding a half slab to that Golems pedestal has worked. PS cussed lava lake.
Does this have the same efficiency in 1.14??
Ilmango. Always doing the best tutorials for the best farms. If only people that came for them would subscribe...
Also: In more recent videos, the best intro as well...
This farm and video have too many unanswered questions: 1) Where is the best place for player to be to have farm active 2) woith high spawn rates does this not fill the mob cap (killing any other farms) so why is there no mechanism to switch it off? 3) do all the surrounding blocks need to be removed or is lighting caves sufficient (best to say so). And I see comments from people saying it no longer works (and slimes cannot spawn on slabs!)!??
1) depends. check the wiki how mob spawning works. usually you want to be at least 24 blocks away from spawning spaces of your farm and have the least amount of spawning spaces outside of the farm within a 128 block range. you see there are a lot of variables.
2) no space for a turn off mechanism. It#s possible to make one, but you need to sacrifice spawning spaces. We showed it in our last server tour how you can implement it.
3) there's a world download. if you have any doubt that something doesn't work check for yourself. usually I don't have the time to answer questions like if mobs can spawn on slabs (yes, they can).
I wonder how slime farms will change with the world depth increase in 1.17
I built this in 1.13.2 on realms and I don't get that many spawns... At what Y should I afk? Right now I am afking in a glass box, around 20 blocks above the farm. Help me, please
I think it is because you are on the Bedrock version and the spawning algorithm might be different for that version
I must admit I'm confused, I what does the slab "hat" seek to achieve in order to improve the efficiency?
The game can check for a mob spawning attempt anywhere, if it ends up failing due to being on a slab then it will try a nearby location, which has a chance to be inside the slime chunk. Having blocks around it at the top makes sure that if that happens anywhere in the surrounding regions it can jump that spawn into the chunk, i think? I'm not sure exactly but the idea is that it redirects a portion of nearby failed spawns into successful slime spawns.
Does water count as a block when it comes to clearing out the space above the farm?
good question. I think it does, because it reduces the light level.
Hey just grabbing this message to ask a question ilmango. Could i raise the farm by 1 block? Would give me more space at the bottom. Because atm the farm is up to y 30 and not y 31. Does that effect the rates?
Thanks for the great design!
Water is a transparent block but with partial opacity. So it reduced light by 2 levels each block but still counts as a transparent block. So, the question is more like, does transparent blocks above the farm affect the spawn rate? If we had glass above it, will it affect sub-chunks spawn height?
And, while at it, why the ceiling around the slime chunk? You never explained why its required and how it affects the spawn rate!
I dont think you are going to read this anymore, but I hope you do.
the slabs around the farm at the top are for making the game start with the spawning algorithm in the space around the farm as well. As some earlier comments said, the spawning algoritm will chose a block to start. from there it can go 5 blocks in each direction (or a 5x5 square with in the centre the initial block. I am not sure wich one, but since the slab roof is 7 blocks wide, it is more likely to be 5 blocks in each direction). So the game will try in that area to spawn in some mobs (I think it will try to spawn 3 different sorts mobs with 4 mobs per sort, with in total 4 mobs) if the algoritm started outside the farm, but it tried to spawn slimes (it can not spawn them outside since it is not in a slimechunk, but inside the farm it can spawn there) some of the area where it starts to spawn can fall within the farm.
the slabs are needed to make sure the games try to spawn mobs in that place as well. As you probably know, if you remove all the blocks above a mob farm, and the farm is in a low y-level, mobs spawn faster, because the game only has to try spawning in a smaller area. if the slabs were not there, the complete subchunk and all the subchunks above would be air and the game would not try to start the algoritm there, resulting in not getting spawns that started in the outside.
I realize I’m a bit late to the party but... could you build a spire of glass outside of the slime chunk and the roof marked out without affecting rates?
Why did you add the roofs? and is it necessary?
Idk
One way you could make the farm slightly more efficient is by extending the rails past the 18 blocks, because when rails curve, they don't pick up items on the corners.
This is pretty much the first thing that came to my mind when magma blocks were introduced :D it didn't occur to me to use iron golems to attract the slimes though, and consequently I just had the traditional four-side drop with hopper-minecarts running along each horizontal line, which wasted a lot of gold - off to make a few changes!
