Stone Breaker

 
Prerequisite(s): Improved Sunder, Power Attack, Two Weapon Fighting, Weapon Focus (any Pick), Str 13+, Dex 15+, Proficiency with any pick, Base Attack Bonus 1+.
 
Benefit: If you hit the same creature with both picks in the same round, you can rend with your picks as a swift action. This attack deals base damage from one pick + 1-1/2 times your Str bonus.
 
Special: A ranger who has chosen the two-weapon combat style can select Stone Breaker even if he does not meet the Dexterity prerequisite.
