The Gauldur Amulet is kind of unique, but still the effects aren't that good. Just +30 to stamina, health and magicka.
Yeah, I absolutely loved that quest (aside from needing to join the mages guild with my warrior character) but was disappointed with the amulet. I would love more quests like that.
There needs to be legendary quality loot, period from stuff that is actually challenging and one time only. Preferably gear that has effects/attributes that cannot be replicated with player crafting to make them appealing.
Absolutely.
