Otto's Tonal Attack (Enchantment/Charm)

Level: 4
Range: 20 yds/level
Duration:  1 turn/level
Components: V, S, M
Casting Time: 4 segments
Saving Throw: Special
Area of Effect: 1 creature

This spell will cause a spell-using
creature to temporarily lose the knowledge of how to
CAST all spells unless a saving throw is made.

Clerics and
druids make their saves at +2. If the save is successful,
then any spell cast by the affected creature is reduced in
effectiveness, as if the spell were cast by a character two
experience levels lower for figuring spell range, area of
effect, duration, or damage.

MC: A sitar string and a crystal mallet (1,000 g.p.), which vanish
after the spell is cast.
