You can use your smiting power to protect an ally from known evil.
Prerequisites
Charisma 13, zeal class feature, smite ability, base attack bonus +5.
Benefit
When you successfully smite an enemy, you may also choose one creature within line of sight other than yourself. That creature gains the deflection bonus to AC against the target of your smite attack. If you smite the same target multiple times, you may grant this bonus to multiple other creatures.
When you use this feat, you may not gain the bonus to AC for smiting the same target, even if you smite the target more than once.
