You can daze creatures with the power of your songs.
BENEFIT
You can modify a song to daze a creature damaged by the song. When a creature takes damage from this song, they become dazed for a number of rounds equal to the original level of the song. If the song allows a saving throw, a successful save negates the daze effect. If the song does not allow a save, the target can make a Will save to negate the daze effect. If the song effect also causes the creature to become dazed, the duration of this metasong effect is added to the duration of the song. Songs that do not inflict damage do not benefit from this feat.
MP Increase: +3 (a dazing song costs 3 additional MP more than the actual MP cost of the song.) In addition, the perform check DC increases by +3.
