Hi guys I had a quick question I was hoping I could get some help with.
What unique items in the game can only be obtained by sacrificing another unique item?
I'm talking about situations like having to choose between the saviours hide and the ring of hircine (I know you can get both by cheating).
I'd also be interested to know if you know of any glitch that can be exploited to receive both items like in the example mentioned above. Thanks.
I don't think those qualify; they're not mutually exclusive. You're supposed to be able to get both rings.
And, for the record: No, the Cursed Ring trick does not work with the rings of blood magic. It only works with rings added by the Dragonborn DLC -- i.e., the two Ahzidal rings, and the four werewolf rings.
This is Twisted's thread so it's his call. Personally though, I'd say no. Since the mechanics for curing lycanthropy and/or vampirism exist for intended use in the vanilla game, anyone can get both items. You just have to go a bit out of your way to do it, but no tricks or exploits required. And once you have the ring of bloodlust, you can use it freely regardless of whether you're a vampire, werewolf, or lame healthy pleb.
