I wouldnt even try without 2500 mana and infinity self weild
You need cta, is not an option.
ES isnt affected by resistances, and you'd want 95% absorb (lvl 40 es)
Even though i agree with you viper/cmoon/spirit can definitely work for a starting nova sorc without cta
I've done it several times last season
Op try to level a bit in some public games but you shouldn't have much trouble to run like keys / pit / cows
Don't do act boss just stick to place without high life mobs
Don't hesitate to over use static
