Darkmantle

While at rest, a Darkmantle looks much like a stalactite. Using a muscular 'foot' it attaches itself to the ceiling, its tentacles wrapped about its body. A darkmantle weighs about 30 pounds and can change its skin color to match the surrounding stone. It effectively has 90’ Darkvision, achieved through a form of echolocation. Magical silence effectively blinds a darkmantle. A darkmantle attacks by dropping onto its prey and wrapping its tentacles around the victim's head to constrict and suffocate, doing 1d4 points of damage. A darkmantle that misses its initial attack will usually fly back to its perch and try again. After successfully attacking, the darkmantle automatically inflicts 1d4 points of damage each round. While attached to an individual, a darkmantle takes half damage from attacks; the other half is inflicted upon the individual it covers. Once per day a darkmantle can cast darkness (the reverse of light, with a 6-turn duration). It most often uses this ability just before attacking.
