The darkmantle hangs from a ceiling by a muscular “foot” at the top of its body. It can look like a stalactite, by holding its tentacles stiffly under itself, or like a lump of rock, spreading its tentacles so the membrane between them covers its body. Its shell and skin usually resemble limestone, but a darkmantle can change its color to match almost any type of stony background.
A darkmantle is about 4 feet long from the tips of its tentacles to the top of its head. It weighs about 30 pounds.
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.
Improved Grab (Ex): To use this ability, a darkmantle must hit a Large or smaller creature with its slam attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity.
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 ability and effectively blinds the darkmantle.
