PoE wiggum-wagon 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

Inspired by the post about eternal damnation and loreweave I made a POB for RF, turns out it isnt that hard to squeeze in, just takes a slightly OP Chaos res ring. Its basically Pohx RF Jugg but slightly changed. I found it impossible to drop purity of Elements with all the gear constraints, but if I would replace immortal flesh it would probably work. Any cluster jewels experts here? Im not familiar with them and I just put in a small one to kinda cheat a little with the Chaos res Original thread:

I probably should have gone omni/doryanis a long time ago, but it is what it is. Never had a lot of cash, and there where always easy to reach goals that didnt require redoing my whole gear. Any suggestions to pump it up even more? Fine with my move speed, going faster is practically useless to me, looking for dmg / survival
