No worries, here's a simple guideline:
Healing takes place based on the wounds themselves (not how much they affect the PC). - For example, a PC with an activated
Pain Editor wouldn't feel any damage at all from his spleen hanging out the side, but the mage is going to be very concerned at the effort involved in healing that wound)
A) The PC has taken Deadly damage (just not died from it), therefore the Mage when healing has to resist drain for the Deadly wound category
B) Pain tolerance has no effect on the healing of the actual wound...as per the
Pain Editor example above.
C) The
Will to Live shouldn't have actually kept the PC
conscious IMHO, but as a GM call it's not an unreasonable action to take, especially if it was fun for all concerned
In an uber-munchkin game from many moons ago, a mage in our group had damage compensators at R9, so didn't take any modifiers from any Physical/Stun damage until he dropped unconscious/dying. Basically, he operated at full efficiency until his body collapsed from damage/exhaustion. Ahhh, fun days....
