Shark Skin: This modification is very complex and borders on a transmutation. By implanting several small teeth all over the skin, the skin becomes abrasive and coarse, causing one to bleed from a touch. Quite simply, the skin adds 1D6 to all non-grapple hand-to-hand attacks, 1D6+5 to all grappling attacks, and makes any person grabbing or grappling with the character take either pinprick (1-2) or minor (1D6) damage per grapple attack! Damage is M.D. or S.D.C. depending on the nature of the recipient, per usual.
Cost: 3 million credits.
