Compound Mimic

Large monstrosity, unaligned

Compound mimics are the unnatural result of concentrated arcane energies infecting the hunting grounds of regular mimics. They are found in dungeons, wizards towers, sewers and other urban areas subjected to high-energy magic for long periods of time.

Compound mimics prefer to lurk as three regular mimics, disguising themselves in the environment as their more reasonably-sized kin do. A compound mimic is content to hunt as individual mimics, and will not morph into its conjoined form unless sufficiently threatened, such as when facing more than three foes or a huge or larger creature.
