possible hit locations like arm, head, chest, and each can be broken down further like leg can be foot, calf, knee, thigh, hip... Chest: what possible organs were hit, how damaged are they... was damage done to muscles, tendons, scrapes, cuts, burns, bones (there are over 26 bones to roll for if the hit was to a foot - don't forget to roll to determining if it was the right foot or left), amount of blood loss, heart stopping, lung puncture, kidney failure, shock... combinations like compound fractures, broken ribs puncturing a lung... was damage caused by a blunt weapon, a projectile, an explosion, an energy weapon, a sharp edged weapon and a slash, a sharp pointed weapon and a thrust... Now for all those possible variations, what are the rules for continued deterioration with no medical aid, how effective is first aid, what can be repaired by surgery, what just needs time to heal... how long is surgery - because surgery for one condition could take minutes while the surgery for something else may take hours or even multiple surgeries over days... what is the difficulty of the first aid or surgery for all the different variations because some things are easier to treat than others... how does the TL of the medical facility effect all the variations... does differences between the air pressure on different worlds effect things? how about differences in gravity?
