You can sacrifice your health to gain an advantage in combat.
Prerequisite: Base attack bonus +6, Iron Will, Power Attack.
Benefit: You may sacrifice a number of hit points (maximum sacrifice equals your character level), taking them from your current hit point total as if you had lost them to damage. For every two hit points so sacrificed, you gain a +1 bonus on attack and damage rolls for i round. Hit points sacrificed in this manner may be regained in the same way that hit points lost to damage can.
Special: Using this feat is a free action, but you may use it only once per round on your turn.
