I'm sorry if there is another place that I should post this question, but I thought that if someone knew the answer, it would be here.
I've recently started a new game of K1 with some mods added, but it was getting glitchy. My main PC is incapable of dying -- I'm reduced to 1 HP, but I never fall down, so I can just keep fighting. I'm not sure what the problem is -- I uninstalled the game, but accidentally said "yes" when it asked if I wanted to save the non-game files (couldn't find them to delete anywhere, though). I reinstalled the game with no mods, and invincibility continued on the Endar Spire (i normally skip it w/ Achilles's Padawan Mod).
You are supposed to be unkillable on the first level of the Endar Spire. Everywhere else though it's probably either a script that misfired somehow (happened to me once with an unmodded game where I ended up unkillable) and "forgot" to remove the Min1HP-flag from the player, or some script in a Mod that sets the flag for some reason.
I think you can remove the Min1HP flag from your character in the savegame with KSE (
