He's just gotten out of a fight where he got smacked around pretty badly. Nothing too serious or permanent, just a lot of bruises and maybe a broken arm.
Then he gets stabbed in the back with a scythe.
Assuming that if the scythe goes far enough into him, the wound would be fatal, how long would it take for him to die? Is there any type of aid that could be given that would help him hold on longer (Like I said, he's a tough old bastard and has an iron will, so he's not likely to let go easily).
