(General)
By singing out a precise tone, you cause discordant vibrations to run through allies' weapons.
Prerequisites
Bardic performance class feature, perform (oratory or sing) 10 ranks.
Benefit
Whenever you are using bardic performance to create a spell-like or supernatural effect, allies within 30 feet of you deal an extra 1d6 points of sonic damage with successful weapon attacks. This damage stacks with other energy damage a weapon might deal. Projectile weapons bestow this extra damage on their ammunition, but the extra damage is dealt only if the projectile hits a target within 30 feet of you.
