Cleric Utility 22Angel of the Eleven Winds

You conjure a luminous winged angel with indistinct features that grants protection and the power of flight to an ally.

Daily        Conjuration, Divine
Standard Action      Ranged 10

Effect: You conjure the likeness of an angel that occupies 1 square within range. The angel grants one ally you can see a fly speed of 8 and a +4 power bonus to AC against opportunity attacks. These benefits last until the angel disappears or until you grant them to a different ally, which you can do as a minor action. When the fly speed ends on an ally, that ally descends safely to the ground if he or she has no means of staying aloft. The angel can’t move or be attacked or damaged, and it lasts until the end of the encounter.
