A cybernetic arm replacement linked into the nervous system, muscles and sinews. It'll function as a replacement for a biological arm but it looks robotic and makes no attempt at imitating a biological arm. Because of its relatively crude design it has less manual dexterity and its sensors aren't as sensitive as a biological nerves. Whenever you use the arm for anything requiring manual dexterity or delicate senses, you operate at a +3 difficulty.
However, the arm's servos are strong and whenever grip strength is in question you operate as if you possessed
Strong to +3.
