I hate Power Attack / Leap Attack b/c they kill the RP flavor for me - too much optimizing number crunching, not enough bone crunching. Too each their own...
But I wonder about this, doesn't it basically grant the 3.0 feat equivalent of flying kick, and would that stack?Sword and Fist from 3.0 was a treasure trove for this. Sandals of Tiger Leaping alone will help you lots. Doubled damage on an unarmed charge iirc.![]()
