This is the resourcepack for the Enhanced Ender Dragon datapack. It does not do anything on its own. It needs the datapack for any functionality. This resourcepack changes the Ender Dragon roars and adds custom JoJo music for the boss fight.
You can find the datapack here: https://www.curseforge.com/minecraft/texture-packs/enhanced-ender-dragon-datapack
Credit for this resource pack goes to Falcon_one and JoJo. I'm not sure whether or not there's a licensing issue with using JoJo music, but if there is, I suppose I can find alternative songs. I honestly had no clue who JoJo was before I worked with Falcon_one's datapack.
