Mimic

Mimics are shapeshifting predators able to take on the form of inanimate objects to lure creatures to their doom. In dungeons, these cunning creatures most often take the form of doors and chests, having learned that such forms attract a steady stream of prey.
While many mimics are instinct-driven monsters, some are gifted with sapience by the trickster demigod Walalal, and these often make acquaintances of Changeling enclaves.
