Each creature in the location is affected by a dominate monster spell (DC 17) urging it to take part in a blood rite. Any creature that fails its save immediately climbs onto the altar, where ancient torture tools animate and attack. The tools attack each round, targeting only creatures on the altar that have failed their saves; they make a single attack with a +10 bonus against each affected creature and deal 1d10 points of damage on a hit. Affected creatures receive a new saving throw each round to end the effect. Once any creature is killed (resulting in its entrails being removed) or 9 rounds pass, the chanting fades away and the affected creatures come to their senses.
