You sever limbs through sheer force.
Benefit: When you are grappling an opponent, a successful check allows you to continue grappling the foe, and also allows you to perform a special sever combat maneuver (see below) as part of the standard action spent to maintain the grapple. Designate a limb (arm, foot, hand, leg) like you normally would when severing a limb, then make a Strength check. This is the save DC for your sever limb attempt. If your target fails this Fortitude save, you rip off the designated limb. This ends the grapple.
You can attempt to sever an arm, foot, hand, or leg at the joint as part of an attack action in place of a melee attack. Normally you cannot sever other limbs than those four extremities, but your GM may deem some special limbs fragile enough to qualify (a wing, for example).
If you do not have the Improved Sever feat, or a similar ability, attempting to sever an item provokes an attack of opportunity from the target of your maneuver. Declare which limb you are targeting before your combat maneuver roll. If your attack is successful, you sever the targeted limb. Your opponent can make a Fortitude save (DC equal to your combat maneuver roll) to ignore the effect. Although horrific, the mind blocks out the pain of losing a limb. This attack deals no damage. The penalties for losing limbs are outlined below.
