I was playing God of War again, which has lots of great bosses and ridiculous amounts of violence. And it got me an idea:
In many RPGs, player characters go unconscious when they lose their last hit point, but are actually dead only once they reach -10 hp. For the sake of simplicity, this is often ignored for enemies, and once they are out of hit points, they are simply dead for all intents and purposes. However, to add a little more gritt to my campaign, I plan to adopt a rule that any enemy brought to exactly 0 hp is not outright dead, but severely enough wounded to go down and lose the ability to fight, move, or even make any loud shouts. So at the end of a fight, there’s a certain chance that two or three of the defeated enemies are still not quite dead and semi-conscious. It’s then up to the players to finish off the dying, ask them a few last questions, use magic healing or treat their wounds so they will survive, or just leave them behind to die.
In Astonishing Swordsmen & Sorcerers of Hyperborea and probably most OSR games, a Trauma Survival check might be appropriate for enemies who are left to die, but the chace for that (default 75%) seems much too high. I probably go with an Extraordinary Feat of Constitution in AS&SH, which would only be 4% for most enemies, and maybe 8 or 16% for the tougher ones. Of course, if an enemy should survive, the GM would be pretty much obliged to have that NPC appear again later on in the campaign.
I can very much see why such a rule doesn’t appear in most RPGs, though I would kind of expect to see it in Lamentations of the Flame Princess. I’m usually not a fan of gore, but I think in this case some additional appaling consequences of violence can go quite a long way to reinforce the feeling of Sword & Sorcery, and also is a great opportunity for players to flesh out the peculiar personalties of their characters.
