Death and Dismemberment

2d6 RESULTS
2 or lower	Instant Death (decapitated or similar death from Conan the Barbarian).
3	Fatal Wound (gutted, stabbed through lung, broken back, and the like) die in 1d20 x 10 minutes. A Wish or similar effect would heal wound. Knocked Out until death unless Save vs Death is made.
4-5	Severed Limb use hit location die, if head rolled and no helmet then as ‘2’, if body rolled and no armor then as ‘3’, otherwise will bleed out and die in 1d6 rounds. Magical healing (magic used for this will not restore lost hp), a tourniquet, or cauterization with fire will allow a Save vs Death with bonus equal to lvl of spell cast, if any. Success means character requires 3d4 weeks of healing. Knocked Out until death unless Save vs Death is made.
6-7	Broken Bone use hit location die. 3d4 weeks to heal. Knocked Out 1d20 rounds unless Save vs Death is made. If head bone was broke and no helmet and failed save then knocked out, “in coma”, until healed instead.
8-9	Knocked Out for 1d12 rounds if wearing a helm. If no helmet then as Broken Head Bone.
10-11	Stunned for 1d4 rounds and lose helm if wearing helm. Knocked Out for 1d12 rounds if not wearing helm.
12+	“Now I’m Mad” a surge of adrenaline returns 1d4 hit points per hit die. At the end of the combat, the adrenaline drains away, hit points are reduced to zero, and the PC faints for 2d6 rounds. If you roll this more than once in a single combat consider yourself a Berzerker under the effects of a potion of super-heroism.
