You can channel positive or negative energy to imbue your allies' weapons with an alignment.
Prerequisite: Ability to turn or rebuke undead.
Benefit: You can spend a turn or rebuke attempt as standard action to align the melee weapons (including natural weapons) of all allies within a 60-ft. burst as good (if you channel positive energy) or evil (if you channel negative energy). Such weapons can overcome damage reduction as if they had the appropriate alignment. The effect lasts until the end of your next turn.
