Necklace of poison immunity comes available to buy fairly cheaply at character level 15, possibly one of the best investments in the game.
You don't realise how extreme the poison damage falmer/chaurus do until you wear one of those beauties. Makes them twice as easy to handle in melee.
Yeah, but if you don't get it then you won't get it. Level78, and my only weakness is damn poison! I had to do alchemy (which I don't like) to get some resistance... Seems it has a bug which makes it be replaced by disease resist amulets after certain level... Bethesda, why don't you fix it! If I were on pc, at least I'd get it by console commands... or if I could get a fix item which was disenchantable (don't like DB, so I won't get their armor, nor saviour's hide, and I hate the look of the dragon priest mask with poison resistance...). Just one amulet which I wanted to buy but hadn't got enough money, and now with 300 thousand gold coins I don't find any. Such a bother...
