So how many stayed dead?
Honestly with the availability of Resurrection as a 3pt Rune Spell getting characters back on their feet after they were killed was never to great of a challenge for us.
Also, do you play that you die at 0 Hit Points? Or is there some buffer?
We always played that you subtracted the damage you were under 0 from 10 and then made a Con roll times that number to see if you survived one more round. So if you were at -6hp you would roll Conx4 to see if you lived another round. The following round you lost another general HP, so you are now at -7, and then had to roll Conx3. Etc.
That which does not kill us makes us stronger. That which does kill us makes us stronger still!
