Divine Power

You swing your weapon in a wide arc around you, creating a halo of divine energy that drives foes back while fortifying you and your allies. The next time you hit an opponent with a melee attack, they get to do a CON save. If they fail they they get pushed back 5 feet, and Until the end of the encounter, you regain 5hp at the beginning of each of your turns, and you and each ally within the burst gain a +2 power bonus to AC. If the creature succeeds, then the spell has no effect on him, you and your ally's.
