Ghouls

Ghouls are Hardmode Underground Desert and Desert enemies. They follow the Fighter AI (behaving similar to Zombies). Ordinary Ghouls spawn inside the normal Desert, the Tainted Ghoul inside a Crimson desert, the Vile Ghoul inside a Corrupted desert and the Dream Ghoul inside a Hallowed Desert. Sometimes these mobs will cause the confusion debuff, so beware when fighting them melee.
