Hell and Herobrine Mod

Minecraft version: 

This mod adds a hell biome, a Herobrine boss, a Hell shack that Herobrine lives in, and devil soldiers that drop devil souls, 9 devils souls can be crafted into 1 compressed soul (thats what the Hell biomes made of) and if you break compressed souls you will get 9 devil souls.

BTW Herobrine attacks Devil Soldiers and vice versa
