How much minus to enemy cold resist on items should I need for pure cold sorc to easily destroy cold immunes (for example I don't wanto see Ancients with cold immunity or so...), and how does it combine with cold mastery?
Tnx.
You will have a very hard time removing immunity with a Lower Resist Wand. It will basically not happen, especially not with Ancients. You need a Necro or Paladin for that.
As soon as the immunity is broken, Cold Mastery will kick in. At this stage though monster, that were previously immune, will have reistances like +140 cold resistance and so even with a slvl32 CM (20 CM, +12 skills) you will "only" be able to bring them to -35% cold resistance.
For none-cold immune monsters and a pure Cold build always, always, always max CM. Then benefit is far bigger than by adding damage. First add -xx% cold resistance, then add damage.
With a pure Cold build you will not be looking for gear with -xx% cold resistance but rather for +xx% cold damage, since CM does not provide that, like other masteries do. Nevertheless cold facets with +5%/-x% are very useful for adding damage, and items like Nightwing's Veil or Death's Fathom.
