Body Slam

 
Prerequisite(s): Reversal, Base Attack Bonus 3+
 
Benefit: You can try to perform a Body Slam as an attack while grappling, but not when pinned. You must declare you are attempting a Body Slam before making an opposed grapple check with a –4 penalty to the roll. If you succeed, you end the grapple, and your opponent becomes prone, as if tripped.
