Stone Power

Stone Power [Type: General]

The principles of the Stone Dragon discipline teach you how to gather and focus your raw, physical strength into an attack.
Prerequisite
STR 13, one Stone Dragon maneuver
.
Benefit
When you use an attack action or a full attack action, or you initiate a Stone Dragon strike in melee combat, you can take a penalty not exceeding your base attack bonus. You gain temporary hit points equal to twice the number that you subtract from your attack rolls. These temporary hitpoints last until the beginning of your next turn.
.
Special
Stone Power can be used in place of Power Attack to qualify for a feat, prestige class, or other special ability. You can take both this feat and Power Attack.
