Glorious Weapons
( Complete Divine, p. 82)[Divine]
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.
