Angelic witnesses
Cleric Utility 2
Close Burst 10
Effect: You conjure a silent, ghostly angel in 1 square in the burst. The angel lasts until the end of your next turn and occupies its square. When an ally adjacent to the angel spends a healing surge, he or she regains 4 extra hit points. For each time you used Healing Word or a Channel Divinity power since the start of your last turn, you conjure an additional angel in a square that’s not adjacent to another ghostly angel.
Sustain minor: the effect persists, and you can move each angel 3 squares.
