Otto's Crystal Rhythms (Evocation)

Level: 3
Range: 10 yds/level
Duration: 2 rounds/level
Components: V, S, M
Casting Time: 3 segments
Saving Throw: Negates
Area of Effect: 1 creature

Unless the victim of this spell
makes its saving throw, the creature’s ears will be filled
with the sound of energetic crystal chimes that no one else
can hear. The creature will immediately drop anything in
its hands and begin clapping, so the creature 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 will be
affected, and any creature with more than one pair of
hands will clap along with as many hands as the creature
has.

MC: A a pair of
crystals worth 500 g.p. that vanish after the spell is cast.
