SQ Mimic Object
Adaptive Resistance (Ex)
The mimic has resistance 20 against any one of the following energy types at any one time: earth, fire, ice, lightning, water, or wind. As a move action, the mimic may change the energy type against which it is resistant.
A mimic exudes a thick slime that acts as a powerful adhesive, holding fast any creatures or items that touch it. An adhesive-covered mimic automatically grapples any creature it hits with its bite attack. Opponents so grappled cannot get free while the mimic is alive without removing the adhesive first. A manufacture weapon, natural weapon, or unarmed strike that strikes an adhesive-coated mimic is stuck fast unless the wielder succeeds on a DC 17 Reflex save. A successful DC 17 Strength check is needed to pry off a stuck weapon. Strong alcohol or remedy dissolves the adhesive, but the mimic can still grapple normally. A mimic can dissolve its adhesive at will, and the substance breaks down 5 rounds after the creature dies. The save DC is Strength-based.
Corrosive Glue (Ex)
The mimic deals an extra 2d6 points of non-elemental damage with every successful bite attack or grapple check.
The mimic’s entire body is a primitive sensory organ. This gives it blindsense with a range of 30 feet, and it cannot be flanked.
Mimic Object (Ex)
A mimic can assume the general shape of any Medium object, such as a massive chest, a stout bed, or a door. 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. A mimic gains a +20 racial bonus on Disguise checks when imitating an object in this manner. Disguise is always a class skill for a mimic.
3/day, a mimic can infect a creature within 30-ft. The target is inflicted with Disease and Sap status for 1 minute. A successful Fortitude save (DC 17) negates the status effects. Blue mages may learn this ability as a 5th level spell (Knowledge: Dungeoneering DC 25).
