Elemental Smiting

 
Prerequisite(s): Ability to Turn creatures with the Elemental Subtype
 
Benefit: Once per round, you can spend a turn attempt is a free action when making a melee attack. If you successfully strike a creature that you could turn with that turn attempt because of its elemental subtype, you may add a bonus on your damage roll equal to your cleric level, if your attack misses, the turn attempt is lost to no effect. For example, a cleric with the Fire domain could use this feat to smite a water elemental or any other creature with the water subtype (since he would normally turn creatures with the water subtype with his domain power).
 
Special: You may only activate this feat by spending a turn attempt that would normally be used to turn creatures with a specific elemental subtype (air, earth, fire, or water). Unlike other divine feats, you can't use a turn or rebuke undead attempt (or other turning attempt) to activate the feat.
