I was looking into the wiki and a lot of people are saying that there is a bug involving poison immunity necklaces after lvl 20. Apparently many people think that the game changes all poison immunity items into disease immunity after said level. I could have swore that I'd found a Poison Immunity Necklace with one of my toons when he was in his 40's or 50's but I cannot remember for sure. Anyone have any solid info one way or the other?
Thanks!
