I just got the Icebane chest, feet and belt to help a little with the Sapphiron fight (and whatever fights beyond him that I'd wear it) and I need to figure out gems and enchants. Do I need to be uncrittable for Sapphiron? If so, i need to load down the new gear with defense gems. I'm guessing that I don't need to be uncrittable though and could go with expertise and stamina gems. Anyone know the answer or can direct me to a resource that does?
