Here are two untested optional rules for hit locations:
Revised Miss by 1 hits Torso: For swinging attacks, a miss by 1 against the skull, face, or neck hits the torso instead. For thrusting attacks, a miss by 1 against the skull or eyes hits the face, a miss by 1 against the vitals, or neck hits the torso. For either type of attack, a miss by 1 against the groin hits the either leg (1-2 and 3-4) or the torso (5-6); optionally, make it torso by default.
Why? This removes the oddness of trying to stab someone in the eyes and hitting their torso instead. Also, of swinging at the groin and hitting the torso only. And the leg never taking the shot for a groin miss is just odd.
Shield Arm and Hand. The shield arm or hand can be hit randomly, past a (strapped-on) shield. However, the roll must be confirmed. If the original "to hit" roll would have hit the arm (-4) or hand (-8), it hits. If not, re-roll. A second result of the same arm or hand hits it regardless!
A hand-held buckler only protects the hand in this manner.
Why? It's weird that the shield and buckler don't actually make getting hit randomly in the covered locations less likely.
I have no idea how these would work in actual play.
