Robot Limb

This is the schtick by the same name from Feng Shui, p 145.

You have an arm or leg, made of an alloy that mixes steel and ARB. This can be an exoskeletal sheathe that strengthens the still existing normal limb. If surgically implanted, it wholly replaces your normal limb. You can buy up to four schticks in robot limb, one for each limb. The limb moves in accordance with your will just as a real arm or leg would, and even has a sense of feel. When relying exclusively on this limb, your effective Strength rating is 12. This is the base Strength used for determining damage of hand-to-hand attacks made with this limb, or by weapons held in this limb.

If you have two robot legs, your Move rating is 12.

The limb is attached to an AI/O port in your shoulder or hip. When unplugged, it moves under the power of an onboard battery pack: the battery is a product of mundane technology and does not contribute to your mutation point total. When running from the battery, your attribute ratings are not boosted by the Robot Limb. While plugged in, it puts extreme strain on both you, both physically and mystically. Each sequence on the Robt Limb costs a single Magic point.
