The Treacherous Mimic

Source: Monster Manual 5e

The Mimic is an aberration of unknown origins that takes the shape of mundane furniture and items to lure prey with the promise of riches and powerful items. One must always keep in mind that Mimics are treacherous and can be anywhere, even in a dungeon that has not been touched by mortal hands for millenia. When dealing with these creatures, it is prudent to remember that they have adhesive properties that mesh well with their instinctual skill in grappling and restraining their prey. Additionally while tranformed Mimics are indistinguishable from a normal object, meaning that they can very easily trick a greedy or uncautious adventurer.
