Any% Random Seed Glitched (Internal) Pre 1.9

Played on 11/3/2024
Sub 20 but still very improvable for me
Category name explanation
There are two sub-sections of random seed glitched listed in the speedrun.com leaderboards: internal and external. External means the runner used glitches that involve exiting the world either by save and quitting to title or force quitting the game via alt+f4 or task manager. Internal means the runner utilized glitches that didn't involve exiting the world. This run is considered an internal run as I didn't exit the world at all during the run and utilized glitches within the world only. In this case, I used a dupe glitch which has you pick up an item in the chest at a specific tick when it explodes to glitch the item, allowing for duplication.
Random seed glitched is also split into Pre 1.9 and 1.9+ where pre 1.9 includes runs done on release versions 1.0 all the way to 1.8.9, whereas 1.9+ includes runs from release version 1.9 all the way to the current version of the game.
Internal dupe glitch explanation
Since I'm not allowed to exit the world at any point during an internal run, I had to use an alternative dupe glitch method that doesn't exit the world. This particular dupe glitch method involves TNT and a chest. By grabbing an item from the chest right as the TNT explodes, the now glitched item should show a red 0 on the hotbar. This glitch is tick perfect. You can then open the inventory, select the glitched item, and right click elsewhere from the inventory to dupe as much of that item as you want as shown at 7:17 of the video. In this case, I went with emeralds in order to trade ender eyes from a clerk and bow and arrows from a fletcher.
Thoughts on the run
Randomly decided to run some 1.8 out of the blue and happened to come across a lucky enough seed to PB in RSI Pre 1.9. Could've done better execution wise which includes losing multiple seconds to trapping a fletcher. The luck while great could've been better if there was a clerk at the first village I was at. Glad to get sub 20 though.
