Forgive me if this is already a mod, but would someone mind making a mod (for Special Edition) that when your reaches zero, you do that thing that essential NPCs do when their health reaches zero, but you can only take one more hit before you do die. To do this, I'm thinking you do something like repeatedly press a button. And, this isn't necessary, but when you're on your knees, NPCs, or at least not all of them, won't attack you as long as you're hobbling away from them.
