Dirge of Doom (Su)
A bard of 8th level or higher can use his performance to foster a sense of growing dread in his enemies, causing them to become shaken. To be affected, an enemy must be within 30 feet and able to see and hear the bard's performance. The effect persists for as long as the enemy is within 30 feet and the bard continues his performance. This performance cannot cause a creature to become frightened or panicked, even if the targets are already shaken from another effect. Dirge of doom is a mind-affecting fear effect, and it relies on audible and visual components.
