D20:Hindering Song Epic Feat

Deafening Song, Perform 27 ranks, bardic music class feature.

The character can use song or poetics to hinder enemy spellcasters within a 30-foot spread from the character. To successfully cast a spell within this area, a spellcaster must make a Concentration check as if he or she were casting defensively, and all such checks have a penalty equal to half the character?s level. The character can choose to exclude any characters from this effect. The character may sing, play, or recite a hindering song while taking other mundane actions, but not magical ones (see the bard?s inspire courage ability for more details). The character may keep up the hindering song for a maximum of 10 rounds. Using the hindering song counts as one of the character?s uses of song or poetics for the day.
