I don't know about anyone else, but one of the biggest things about Skyrim that bugs me is that followers are either: a) Completely immortal (aka Essential) b) Completely immortal to everything BUT will die to a careless swing of a player's weapon (aka Protected) c) Utterly useless and will die to everything (aka neither essential nor protected) Various follower mods allow you to manipulate the state of your followers between these states, but the problem is that NPCs that are neither essential nor protected never regen any health at all. You can check this stat in the console by clicking an NPC and using "getav healthregen", as you might know already, and this value is always 0.00 unless you make the NPC protected or essential in which case its 0.70 by default. Indeed, you can manually set the value as well with setav healthregen, but upon loading the game or going through any load-door the value always resets. It means trying to play the game such that you actually have reason to fear for your followers' lives is near impossible, because if its possible for them to die then they do not regen health at all - meaning after one or two enemies they will pretty much die to anything. The only way they can reasonably stay alive through multiple fights, by having health regen in between, is to make it so they cannot die in the first place. It seems awfully silly. I poked around in the CK a bit, couldn't seem to find any obvious differences between Actors who're Essential/Protected and those that weren't, health regen doesn't even seem to be a value set per individual actor in the CK despite the fact you can change it per actor in game. Does anyone know how the game handles health regen for NPCs, and is it ever possible to set an NPC to non-essential or non-protected without removing their health regen? I wanted to try to see if I could make this mod even if it required some kind of scripting, but I'm not even sure where to start, and searching the forums didn't seem to produce many results on the subject. P.S. I did find this mod: http://www.nexusmods.com/skyrim/mods/44822/? but it is implemented in a fairly confusing way and I couldn't get it to work at all.
