The logic of whether the weapon CAN to non-lethal damage or not is kinda besides the point, I agree the logic of it doesn't make much sense in that regard either but the main point I am making is that non-lethal damage in this game has literally zero impact in almost every scenario in the game beyond maybe 2 points where it inexplicably does for some reason.
Modify non-lethal attacks to the point it has at least some narrative difference on the game. I can understand the guys raiding Withers tomb disappearing after they wake up if you don't kill them since they would just run off somewhere. But goblins raiding the grove or those in the grove if you raid it or the fact that knocking the hag's victims family out still counts as killing them.
Shouldn't have a case of unconscious equals dead in almost all situations except a few because "Reasons".
