Ebony Tendrils

This spell summons a lump of blackness five feet in diameter with four 10-foot arms radiating from it, 90 degrees apart. Touching the central lump causes death unless a save vs. death is made. The arms attack with the same chance to hit as the cleric casting the spell, inflicting d10 +2 hit points of corrosive and constriction damage. Creatures struck have one chance to break free, which is the same as the chance to open a door. (If the chance to open doors is unknown, assume that smaller than man-sized creatures escape on the roll of a 1on 1d6, man-sized creatures on a roll of 1or 2 on 1d6, and larger than man-sized creatures on a 1,2, or 3 on 1d6).
The round after scoring a hit, an arm retracts into the central lump, where the victim in its grasp must save vs. death. Thereafter, the victim is held fast and continues to suffer corrosion and constriction damage, but continued contact with the lump does not cause additional saves vs. death. Broken arms retract into the central lump without making further attacks. Arms holding dead creatures continue to hold them until the spell duration expires.
