Hook:
This uses a bent arm, swinging the arm around to strike the
victim, usually to the jaw or side of the head. It is a power punch and
uses movement of
the body as much as the swing of the arm. It suffers a +15 penalty to
hit, but does 1D4 DMG. The victim must then make a Save Vs Hitting or
be knocked out for 2D4 rounds - (STA ÷10) rounds (Minimum of 1 round).
