mod: Hardcore Ender Expansion reason: It adds a new outlook on the end making the ender dragon much more of a challenge and giving us more like new bosses different end items new achievements new biomes in the end and much more. This is for players that have close to nothing to do. link:https://minecraft.curseforge.com/projects/hardcore-ender-expansion
I really loved HEE on an old pack I used to play, it adds exploration to the end, a bunch of cool things and a way for players to reset the end at will.
