Adhesive (Ex): A mimic exudes a thick slime that acts as a powerful adhesive, holding fast any creatures or items touching it. An adhesive-covered mimic automatically grapples any creature it hits with its slam attack. Opponents so grappled cannot get free while the mimic is alive without removing the adhesive first. A mimic makes one automatic slam attack each round against any creature stuck to it.

A weapon that strikes an adhesive-coated mimic is also stuck fast unless the wielder succeeds at a Reflex save (DC 16). A successful Strength check (DC 16) is needed to pry it off.

Strong alcohol dissolves the adhesive. A pint of wine or a similar liquid weakens it, but the mimic still has a +4 bonus to grapple checks. A mimic can dissolve its adhesive at will, and the substance breaks down 5 rounds after the creature dies.

Mimic Shape (Ex): A mimic can assume the general shape of any object that fills roughly 150 cubic feet.(5 feet by 5 feet by 6 feet), such as a massive chest, a stout bed, or a wide door frame. The creature cannot substantially alter its size, though. A mimic's body is hard and has a rough texture, no matter what appearance it might present. Anyone who examines mimic can detect the ruse with a successful Spot check opposed by the mimic's Disguise check. Of course, by this time it is generally far too late.

A mimic often surprises the unsuspecting adventurer, lashing out with a heavy pseudopod. Mimics are smart enough to avoid fights to the death by extorting treasure or food from a party.

Shapechanger Subtype

Traits: A shapechanger possesses the following traits (unless otherwise noted in a creature's entry).
