Hero's Beacon
Bard Attack 29

Your weapon erupts in blazing light that ignites your foe in radiant flames. The light of those flames persists, healing your allies and searing your enemies.

Melee weapon

Target: One creature

Attack: Charisma vs. AC

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

Effect: The attack creates a zone of bright light in a burst 2 centered on the target. The zone lasts until the end of the encounter. When the target moves, the zone moves with it, remaining centered on it. Any ally who starts his or her turn within the zone regains hit points equal to your Charisma modifier. Any enemy that starts its turn within the zone takes 10 radiant damage.

Hero's Beacon is a daily power available to bards at the 29th level.[PH2:77]
