There are many things in this modification, for example: Frozen Coal, Frozen Wood, Frozen Zombie. The strongest in the modification is Devil's Zombie with 40 hearts. The best biome is Frozen, or Frozeneb. The strongest weapon is the Antigravity Sword, 32.5 hearts. In this mod you have to survive (I don't recommend playing in hardcore mode).
