Yith

The Yith is a War Mode monster about as rare as a pinky. It spawns during Cthulhu Mythos. When you encounter a Yith if there are any monsters nearby it uses psychic powers to inhabit the monster and make the monster extremely hostile towards you. It can inhabit every monster except critters, NPC's, Players, and Bosses. The damage it does depends on the monster and after all monsters are killed it starts fighting. It is like a worm in which it tunnels up and hits you then charges at you with claws then sinks back down.
