Hindering Song (Feat)

Prerequisites: Deafening Song, Perform 24 ranks

Benefit: You can use song or poetics to hinder enemy spellcasters within a 30-foot radius centered on you. 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 your level. You can choose to exclude as many characters as you wish from this effect. Hindering Song is a performance, and requires entering and sustaining the performance stance, just like any other performance.
