Recently a PC managed to lose a leg in a fight (Just above the knee) from a critical hit. I used the 2ed Player's option: Combat and tactics, Critical Hit Table for it and she had some rather unfortunate rolls. She was reduced to 0 HP and suffered severe bleeding. The tide of blood was stemmed and she was left in the negatives.
My current issue is that I can find no rules anywhere in any edition or rule set for recovering after losing a limb. It seems everyone assumes as soon as they're back at 1 HP they are fine and dandy. I'm by no means an expert, but it seems to me that someone would not recover so easily from that kind of trauma.
I'm wondering if any of you have seen any rules on that sort of thing. I also remember hearing from somewhere about reduced max HP until an amount of recovery time has passed, but that was years ago and I can't recall any details. Perhaps I'm being too strict, but I'd like to do this properly.
Keep in mind I'm not asking for things like minuses to skills as a consequence of missing a leg. There are clear rules on that as are with prosthetics. I am simply looking for rules on recovering and surviving the trauma.
Thanks in advance.
