k, im not sure what cold mastery caps out at but i know conviction can only have -150 res. and lets say they have 4 facets, so -170 right. k since your base is 0, then you lose 40 for nm, and another 60 for hell, right? well anyway thats -270, so if u want to have 75 res u need a whopping 345 all res, just 315 with all anya quests. thats if you want max hell res. for max nm res you only would need 255. if im makin a stupid mistake please let me know, too lazy to open d2 and actually look at it :yawn:
btw i wasnt very clear the max negative resist you can have is -100
