Corrupt Mimic

s are a bigger, more offensive mimic. They will leap at the player through walls and have a very large amount of HP, and will occasionally close themselves to prevent all damage. They behave like normal mimics.

The Corrupt Mimic is a Hard Mode monster, so it cannot be encountered naturally before the Wall of Flesh is defeated. Corrupt Mimics can be spawned by putting a Key of Night into any chest. The chest will then turn into a Corrupt Mimic.
