This new blessing complements the War Saint multiclass archetype.
Righteous Smite (Su): At 1st level, you can call out to the powers of good to aid you in your struggle against evil. As a swift action, you choose one target within sight to smite. If this target is evil, you add your Charisma bonus (if any) to your attack rolls and adds your warpriest level to all damage rolls made against the target of your smite for 1 minute. Regardless of the target, smite evil attacks automatically bypass any DR the creature might possess. The smite evil effect remains for 1 minute or until the target of the smite is dead.
Righteous Judgment (Su): At 10th level, you can grant the righteous smite ability to all allies within 10 feet, using your bonuses. Allies must use this righteous smite ability by the start of your next turn and the bonuses last for 1 minute. Using this ability is a free action. Evil creatures gain no benefit from this ability.
