Glimpses of Hyboria
Power Attack (General)
You can pour your strength into your blows to wreak devastation upon your enemies.
Prerequisite: Str 13.
Beneﬁt: On your action, before making attack rolls for around, you may choose to subtract a number from all melee attack rolls and add the same number to all melee damage rolls. This number may not exceed your base attack bonus. The penalty on attacks and bonus on damage both apply until your next turn.
Special: If you attack with a two-handed weapon, or with aone-handed weapon wielded in two hands, you instead add twice the number subtracted from your attack rolls. You cannot add the bonus from Power Attack to the damage dealt with a light weapon (except for unarmed strikes or natural weapon attacks), though the penalty on attack rolls still applies.
