Discordant Voice (Feat)
By singing out a precise tone, you cause discordant vibrations to run through allies' weapons.
Prerequisites: Level 11, Bardic Performance class feature, Perform 10 ranks
Benefit: Whenever you are using a bardic performance to create a spell-like or supernatural effect, you project a continuous aura to all spaces within 30 feet of your space. This aura affects allies within 30 feet of you, so that they deal an extra 1d6 points of sonic (energy, common) damage with all successful weapon attacks. This is bonus damage which stacks with other energy damage(Sonic, Fire, Electricity, or Cold) a weapon might deal, although each damage type might be resisted or trigger a vulnerability independently.
Projectile weapon attacks bestow this extra damage on their ammunition,, and thrown weapons are affected as normal, but all ranged attacks deal the extra damage only if the projectile hits a target also within the aura, ie, within 30 feet of you, the Bard providing the effect. If a weapon has a splash effect, the bonus damage is inflicted upon the primary target and also upon all creatures affected by the splash.
