Reduce the wounding multiplier of large piercing (pi+), huge piercing (pi++), and impaling (imp) damage to x1. Any major wound (loss of over ½ HP from one blow) cripples the limb. Damage beyond that threshold is lost. A flyer with a crippled wing cannot fly.
An attack that misses by 1 hits the torso instead. Heart, lungs, kidneys, etc. Increase the wounding modifier for an impaling (imp) or any piercing (pi-, pi, pi+, pi++) attack to x3. Increase the wounding modifier for a tight-beam burning (burn) attack to x2. Other attacks cannot target the vitals.
