So I've gotten an idea, of a fairly easy, extremely simple, yet I think very immersive mod. I know now how to create resistance to normal weapons, and possibly even, total immunity. Normal weapons being anything that is steel, iron, imperial, or wooden. Unfortunately I can't replicate the "If it is or isn't enchanted" thing from Morrowind, and unarmed has no keywords afaik, but I can get something very similar, which is still much better than vanilla Skyrim in that regard.
I don't know about you, but personally being able to kill golden saints with an iron dagger, just totally destroys my ability to see daedra as these very powerful, unearthly supernatural creatures... And I bet I'm not the only one irritated by that.
So in theory I'd just add the immune to normal weapons effect to all ghosts and daedra, and then the sense of accomplishment from your first dwarven or silver weapon is that much bigger- and you'll value these types of weapons so much more. Only one specific little issue.
Only problem is, wouldn't new daedra and ghosts added by other mods still be attackable with iron daggers (and other common weapons)? How would I get around this? Could I somehow make a perk that applies to an entire race ingame?
