Shout of Defiance (Su)

You can channel holy energy into a righteous shout of defiance. As a standard action, you can expend one use of mythic power and one use of either channel energy or lay on hands to create a 100-foot spread of healing energy. All allies within this spread heal a number of hit points equal to 1d6 plus double your tier. If this brings an ally from negative hit points to 0 hit points or more, the ally can immediately stand up from prone without provoking an attack of opportunity.
