Song of Compulsion

To set this spell in motion, the caster sings the first verse of a popular and mindless traveling song having many verses (such as "Ninety-Nine Barrels of Ale on the Wall"). Song of compulsion prevents the affected beings from taking offensive actions, casting spells, using psionic abilities, using magical items, or leaving the area of effect until they finish the song (which is assumed to occur when the spell duration expires). Affected creatures may still defend themselves (that is, they receive no Armor Class penalties) and move about within the area of effect, and the effects of a song of compulsion on any creature are negated if it is attacked.

The effect is centered on a point selected by the caster, and it affects persons selected by the caster within the area of effect. If the spell is cast at three or more beings, each gets a normal saving throw; if only two creatures are being enspelled, each rolls its saving throw with a -1 penalty; if the spell is cast at but one creature, its saving throws suffer a -2 penalty. Saving throws are adjusted for Wisdom. Those creatures who succeed in their saving throws are totally unaffected by the spell. Mindless undead creatures and undead creatures with (individually) more Hit Dice than the caster has experience levels cannot be affected by a song of compulsion, and neither can beings who cannot hear or do not understand the language of the caster (although the caster may employ magical means to make himself or herself understood and then affect such creatures).
