Feng Shui: The Lost Island
You have an arm or leg made of an alloy that mixes steel and ARB. (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 would, and even has a sense of touch. 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, and any Manual Dexterity-based check using the limb suffers a -2 Action Value penalty. Add 1 to your end-of-session mutation check difficulty for each fight in which you power up your robot limb or limbs, and for each out-of-combat check you make using an attribute boosted by a robot limb. This includes skill checks
