I am thinking of refining my armor to have max resists using Invulnerability refinements since there is a chance of not getting one resist which one would you choose? I am thinking cold but not sure if that is the best choice. I know I have the option to try again if I don't get five, I just don't have the resources right now. Or I am better off chancing poison since most poisons don't last long with vampire form running? I use my sampire for most challenges other then the roof right now. Any thoughts?
