Countersong

Countersong
Abjuration [sonic]
Range: 50 feet
Effects: Sound-based or sonic effects
Duration: See text (no more than 1 round/level)

You use a powerful note to counter magical effects that depend on sound (but not simply spells with verbal components). Once the note has been cast, you can continue singing as a free action each round. Each round of the countersong, you make a performer check. Any creature within 30 feet (including you) who is affected or could become affected by a sonic or language magical attack may use your performer check result in place of a saving throw if the performer check result proves to be better. This music can be used preventatively.
