For those who pick the Server hopping bosses for mastery method here's my suggestion for each sea: 1st sea - Grind Thunder god Boss. It is not a difficult boss if you have ranged fruit like Light which is best fruit for 1st sea. Also flame fruit is also an option to beat this boss as flame has good damage and decent range. Just keep your range from the boss and you are good to go. I didn't suggest Cyborg boss because it is very difficult boss for 1st sea players as it as good AOE attacks which would get you even from far range. Tip - Don't grind Cyborg boss. Instead grind Thunder God boss. 2nd sea - Grind either Awakened Ice Admiral boss or Tide Keeper boss. These boss give lots of mastery and are not that hard to kill if you are a buddha user which I highly recommend in Second sea. Awakening Buddha is even better. If you are having problem with Tide Keeper boss as it summons a Sea beast which is very annoying, you can also grind Smoke Admiral boss too for mastery. Smoke Admiral wall glitch would help you a lot. Just hit him 1 time, then go behind the other side of the wall and spam m1s or your blox fruit abilities if you are a logia user in 2nd sea. Tip - If you have become pro then only grind Tide Keeper boss for mastery otherwise if you aren't that good as 2nd sea player you might get destroyed by him. Grind Smoke Admiral boss only if you can't grind Tide Keeper boss. 3rd sea - Grind either Longma boss or Cake Queen boss or Captain Elephant boss. Longma boss can be found behind the entrance of Turtle island and you can glitch into its wall by flash step but you won't be able to attack it You must unlock his gate first. If you wanna know how to open Longma boss gate then search up RUclips. Captain Elephant boss can be found in the Turtle Island too. Just front of Mansion then go left there is the Boss. This boss is kinda annoying as it spams Twin Hooks X and Z move which can fr be very, very annoying. By very I actually mean very annoying. If you are still using a Logia fruit in 3rd sea I totally suggest you too stop. Buddha fruit is the best and only choice for grinding anything in 3rd sea. Cake Queen boss can be found in the Sea of treats island which is just behind the Castle on the sea. Go straight behind Castle on the sea and there it is the island. When you reach there you will see a giant ice cream scoop and a spoon as it's ladders, climb it up and there is the boss. This is likely the top 3 hardest boss in whole of Blox fruits so you must have a good sword or fighting style paired with Buddha to kill this boss otherwise this boss will be a real pain for you. This boss might be difficult than even Captain Elephant boss which could depend upon how you play. Tip - I don't recommend Cake Queen boss for mastery. Many people grind it for mastery so there are low chances you will find it in each server hop or even after 10's of server hops. This boss is also difficult to beat so if you wanna save more time and get mastery but don't take time then grind Captain Elephant boss or Longma boss. Stone boss is also an option. It is found in the Port town where you enter from 2nd sea to 3rd sea behind the buildings and in the middle of the island. For those who wanna grind NPCS: 1st sea - Grind Galley Pirates or Shanda. 2nd sea - Grind Snow lurkers or Lab Subordinate. 3rd sea - Grind at the Chocolate island every NPC. Go in circles and gather them up then kill them 1 group at 1 time. Follow this trick in every sea. This took a lot of time typing so if I get a pin it will be worth it :) Also W video

I also suggest Beautiful Pirate. she gives alot of mastery and isnt hard to kill. The quest of her also gives 50k which is useful for money too.
❤❤❤ wow your good
even better way - use cyborg v4 at chocolate land 300 mastery per 10mins
