Custom missile arm

A rocket arm is a hollowed-out droid arm with servo controls replaced by a short-range rocket engine and fuel. The arm suffers a -3D penalty for any actions that require fine manipulation, but it can be aimed and fired at a target, acting like a dumb missile. Installation of the rocket arm requires a Difficult droid programming/repair roll. If the roll fails by 5 or more, the detach system is faulty and, when fired, the rocket will remain attached, detonating the following round.
