I like this idea. Anyway, here\'s my contribution.
Bleeding to death: I think that this can be used with \'overall\' damage. Overall damage would be the overall HP that you have, for every single part of your body combined. Basically, when you are knocked down to a certain percentage of your HP, you die. This is, once again, your overall HP, and arms and legs need blood, as does the brain and body. Not that I needed to point that out, but do Kran have blood?
This would mean different heal spells, too, I think. Maybe they can just heal overall HP until you\'re completely healed, but the blood loss idea, in my opinion, has some merit and would have to be replenished through time, potions, and food.
Also, Diaboli have tails (I think).
With a body-parts system, perhaps there can be things that hurt a particular part of the body. Like noxious fumes hurting the head, falling down hits the part of he body that is landed upon hardest, and so on.
