Hit Locations
Yes, and it works for Percentile as well as D20 systems, with a little tweaking... On either, you look at the second digit (if any) of the hit.
1 = Head/Neck
2 = Chest/Back
3 = Abdomen/Lower back
4 = Groin/Buttocks
5 = Left arm
6 = Right Arm
7 = Left thigh
8 = Right thigh
9 = Left leg
0 = Right leg
I don't break it down any further than that. Note that, in most cases, odd numbers are on the left side of the body, even on the right (if that's of any importance to you). I usually ignore these rules, unless (for instance) an unarmored Mage-type is wearing a helm(et), providing only his head with protection...
