Your foe's offenses return to it as a wailing storm that engulfs its allies while your bow shots repay its evil deeds in full.

Standard Action      Ranged weapon

Target: One creature

Attack: Charisma vs. AC

Hit: 4[W] + Charisma modifier thunder damage.

Miss: Half damage.

Effect: The target is affected by your anthem of antagonism (save ends). While it is affected by the anthem, at the start of each of your turns, the target is the center of a burst 5 explosion of clashing noise. Each enemy in the burst takes thunder damage equal to your Wisdom modifier. You gain a power bonus to the attack roll of your next ranged weapon attack on that turn equal to the number of enemies that take damage in this way.
