Stone Power

STR 13, one Stone Dragon maneuver,

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 of as much as -5 on your attack rolls. This number cannot exceed your base attack bonus. You gain temporary hit points equal to twice the number that you subtract from your attack rolls (to a maximum of+10). These temporary hitpoints last until the beginning of your next turn.

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.

The principles of the Stone Dragon discipline teach you how to gather and focus your raw, physical strength into an attack.
