Just a simple addition to system - random damage slots.
For example you get "fell slash - hand" so you can treat it with gauze on hand slot.
This addition opens new possibilities, for example tire Cramer for fixing breaking legs. Crippled zones will give various debuffs to you. Also it will give more realistic model of body damage and stop forcing players to prioritize they treatment sequence. I think this will be nice.
Just a general idea for future updates, no rush.
