In Dungeons & Dragons, a mimic is a type of fictional monster that can change its shape to disguise itself as an object such as stonework, doors, or chests. When a character or creature touches the disguised mimic, the mimic can lash out with a bludgeoning pseudopod. A mimic excretes an adhesive glue to hold fast whatever touches it. The mimic can assume the general shape of any object that fills roughly 150 cubic feet (4.2 m3) ). Mimics were designed to guard treasure or secrets, and they werent meant to be the bloodthirsty monsters that plague dungeons that we know them as. They were a defense system. Mimics are weak to alcohol, and they are sunlight sensitive. The origins of the mimic are not clear, but it is an iconic figure of the modern fantasy genre, best known for disguising itself as a treasure chest to tempt and ensnare adventurers and turn them into a meal.
