Otto's Crystal Rhythms

Unless the victim of this spell makes a successful saving throw vs. spell, the creature's ears are filled with the sound of energetic crystal chimes that no one else can hear. The creature immediately drops anything in its hands and begin clapping, so it cannot use its hands for anything else. Spells requiring a somatic component cannot be cast, thieving skills cannot be performed, tools cannot be used, and weapons cannot be wielded by the clapper. Obviously, only creatures that have hands are affected. Any creature with more than one pair of hands claps along with as many hands as it has.

The material component of the spell is a pair of crystals worth 500 gp that vanishes after the spell is cast.

Notes: Uncommon or rare spell (WoG).
