Three splinters of bone, believed to belong to Leopold of Murnau, were worked into a set of heavy jailer’s keys kept on a thick iron ring. When the holder touches the keys to a supernatural creature, he makes a Wits + Conscience roll (the difficulty is the target’s permanent Willpower). Each success is one turn in which the target creature is completely immobile and drain 1 Willpower point. The keys must remain together to work.
