Combat

A darkmantle attacks by dropping onto its prey and wrapping its tentacles around the opponent's head. Once attached, it squeezes and tries to suffocate the foe. A darkmantle that misses its initial attack often flies up and tries to drop on the opponent again.

Darkness (Su): Once per day a darkmantle can cause darkness as the spell cast by a 5th-level sorcerer. It most often uses this ability just before attacking.

Improved Grab (Ex): To use this ability, the darkmantle must hit with its slam attack. If it gets a hold, it can constrict.

Constrict (Ex): A darkmantle deals 1d4+4 damage with a successful grapple check.

Blindsight (Ex): A darkmantle can "see" by emitting high-frequency sounds, inaudible to most other creatures, that allows it to ascertain objects and creatures within 90 feet. A silence spell negates this and effectively blinds the darkmantle.

Skills: A darkmantle receives a +4 racial bonus to Listen checks. *This bonus is lost if its blindsight is negated. The creature's variable coloration gives it a +4 racial bonus to Hide checks.
