Mimic

Occasionally, a Chest will turn out to be a mimic. There are a few ways you can check:
 * After clearing a chest room, the chest will not unlock, and (if they were closed) the doors will not open.
 * If a mob walks into it, the chest will be pushed around.
 * Any attacks you make that hit it in any way will cause it to aggro and attack you.
 * When you press your map button during combat, rooms with a Mimic in them will not show the chest symbol.
