Song of Requiem

From NWN2Wiki

Type of feat: Class, Epic

Prerequisite: Bard 21, Perform 24

Required for: Hymn of Requiem

Specifics: This song damages all enemies within 20 ft for 5 rounds. The total sonic damage caused is equal to twice your perform skill; the minimum damage caused per target is one-third your perform. For example, with perform 30, a total of 60 points of damage is inflicted each round. If six (or more) enemies are affected, they would each take 10 sonic damage per round.

This and the Hymn version are currently bugged in that they deactivate any inspirations you have going.
