So I've been throwing around ideas to incorporate the wonderful crit system into regular wounds, to create a grittier world. MY stumbling blocks have been focused in when to have PCs hit with just Wounds fall unconcius- but after reviewing a few other games, I think I have a solution for that problem.
Dangerous Wounds:
In a game with this houserule, combine your wound and strain thresholds into a single large number. Track wounds and strain separately, but you fall unconcius if both numbers add together to pass the combined threshold. (IE: a human with 2 brawn and 2 will has a Combined Threshold of 24- if he takes 20 stun, he's still up, but a 5 damage blaster bolt on top of it will put him down)
Though strain generated by abilities and threat remain the same, Stun weapons do twice what the do under normal rules. Lethal is not doubled, but when lethal damage is done, (above soak) take a critical hit, adding twice your current Wounds to the d100 roll. (this replaces the +10 for multiple crits, but not for Vicius or Lethal blows). Paying advantage to activate a crit adds 10 to the roll as normal. (So a human with 20 wounds is still concius, but is rolling for a crit with +40 on the chart)
I'd like to test this houserule at some point for a gritty AoR game- what are people's thoughts?
