Boils/Guts

Tree Boil
Tree boil is exactly like a boil but spawns dopels covered in vines. By unknown.

Necrosis
behaves in a manner similar to Boils. The primary difference is that instead of firing blood, Necrosis spurts out black pestilence forming pools of creep. They fire in intervals of five seconds, and on death leave a pool of creep as well. Unlike Gish, the creep deals damage, rather than slowing the player down. By unknown.
