As supremely adaptive creatures with truly aberrant physiologies, mimics sometimes develop new powers as they mature into adulthood. A mimic’s spawn inherit its powers and may mutate further, resulting in mimics with multiple unrelated abilities (for example, the subterranean mimic has the bioluminescence, gillfoot, and hypersenses abilities).

The following represent several options for creating unique and deadly camouflaged hunters of the deep, along with the recommended CR increase for each.

The mimic ignores extra damage from critical hits and sneak attacks 50% of the time.

The mimic has resistance 20 against any one of the following energy types at any one time: fire, cold, electricity, or sonic. As a move action, the mimic may change the energy type against which it is resistant.

The mimic can choose to shed light from any part of its body, ranging in intensity from a soft glow like that of a candle (shadowy illumination in a 5-foot radius) to the full brightness of a torch (bright light in a 20-foot radius and shadowy illumination for an additional 20 feet). The mimic may duplicate any color of light it so desires, even creating multiple colors, and may cancel or resume use of this ability at will as a free action.

The mimic deals an extra 2d6 points of acid damage with every successful slam attack or grapple check.

The mimic has climb speed 5 and swim speed 5. The mimic may always take a 5-foot step in any combat round, even if difficult terrain or other factors reduce its speed. A mimic may take this 5-foot step whether it is on land, climbing, or swimming. It can breathe water as easily as air.

The mimic can create wings and has a fly speed of 40 feet (clumsy maneuverability).

The mimic has fast healing 5.

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.

The mimic’s slam attack deals bludgeoning, piercing, and slashing damage. The damage for its slam attack improves by one die step.

The mimic gains DR 5/adamantine.

The mimic can squeeze into a space as small as 1/4 its base size. Its reach increases by 5 feet and it gains Combat Reflexes as a bonus feat.

The mimic’s flesh is poisonous (type contact; save Fortitude DC 10 + 1/2 mimic’s HD + mimic’s Con modifier; frequency 1/round for 4 rounds; effect 1d2 Constitution damage; cure 1 save). Creatures hit by the mimic’s natural attacks or attacking it with unarmed strikes or natural weapons are subject to this poison.
