Knee

Knee attacks are counted as a Thrusting Attack, doing Very Blunt damage equal to the attacker's Strength by default. They suffer from an intrinsic -1 AM except when used during an ongoing Grapple or Hold, default to hitting Groin and ignore the normal penalty to strike Guts, Groin or Leg but suffer double the normal penalty to strike anywhere else. Headbutts can be used by both parties while grappling.
