PoE Spell Totem, Templar, Nova builds

So far I I copied most of this from some easily available SW Totem builds, which are way, way too expensive though. The goal for this is a sub 5d char that excels at sanctums Basic concepts: Full cold convert, hrimsorrow rn, later might go veiled mod 35% phys to cold 40% Mastery +?? Heatshiver go hiero, get battle mage from forbidden jewels (way cheaper than getting +1 totems as an inq, that alone is 10 d at least) Use marohi+astral projector Go crit, its convinient with the the skills/path, but maybe I should go nc with hiero? (No idea) Creeping frost Totem for chill Arc brand/ass M
