Combat Stamina

Prerequisites

Benefit You gain a stamina pool. After you make an attack roll with a manufactured weapon, unarmed strike, or natural weapon attack with which you are proficient, but before the results are revealed, you can spend up to 5 stamina points. If you do, you gain a competence bonus on the attack roll equal to the number of stamina points you spent. If you miss with the attack, the stamina points you spent are still lost.

Special Since you have a stamina pool, you can spend your stamina points to use any combat tricks associated with combat feats you possess.
