Strength Devotion

 
Prerequisite(s): Access to the Strength Domain.
 
Benefit: Once per day as a swift action, you can bypass hardness with your melee attacks for 1 minute. In addition, you gain a slam attack as a natural weapon, and all your melee attacks (natural or not) gain the adamantine property for the purpose of overcoming damage reduction. As a natural weapon, your slam attack does not provoke attacks of opportunity. It deals damage based on your size and character level, as given on the following table.
 
Level: Damage S/M/L
1st-5th: 1d4/1d6/1d8
6th-10th: 1d6/1d8/2d6
11th-15th: 1d8/1d10/2d8
16th-20th: 1d10/2d6/3d6
 
If you already have a natural weapon, use whichever damage value is higher. You gain a +2 circumstance bonus on any damage rolls you make with that weapon.
 
Special: You can select this feat multiple times, gaining one additional daily use each time you take it. If you have the ability to turn or rebuke undead, you gain one additional daily use of this feat for each daily turn or rebuke use you expend.
