Smash

While in a defensive stance, the stalwart defender may make an extra slam attack per round (even if he doesn't normally have a slam attack). If used as part of a full attack, the extra attack is made at the stalwart defender's full base attack bonus –5. The smash deals 1d4 points of damage (if the stalwart defender is Medium, or 1d3 if he is Small) plus half the character's Strength modifier.
