This mod, now adds a mod called End Zombie. He is extremely agressive and he spawns in the End Highlands.
It adds an ingot called End ingot, and to do it, you need to kill the End Zombie to get the end nugget to do the ingot. With the ingot, you can do a pickaxe, a sword, and a armor. With the rotten flesh you put it on the furnace and it will transform into a shulker shell.


I'm still doing it, so I will add more entities to the mod.
