RETRACTABLE CLAWS

Retractable claws are implanted into your hands.  The claws are typically made of ceramic or carbon fiber compounds with durability and hardness rivalling steel.  The claws also assist in climbing and may be used as a melee weapon. You gain a +2 equipment bonus on Athletics checks to climb. If you beat the DC of a Climb check by 5 or more, you are not considered flatfooted while climbing. 

Attacks with your retractable claws are considered unarmed strikes.  Any feat that modifies an unarmed strike modifies attacks with your retractable claws. Your retractable claws grant +1 damage per damage die and all damage is considered lethal.  Your claws are not subject to disarm attempts but may be sundered while extended.
