PoE builds similar to POE 3.9 CI CoC Trickster minotaur full run

I elaborate a CoC Icenova around 1 or 2 ex max (cheap 6 link) can someone help checking the PoB that understant about CoC builds, I think theres a looooot of room for late game. This build is designed to rush red maps, delve, contracts and not hardcore stuff. POB:

I really only want a decent ES roll and 14%+ CDR on it (I'm already overcapped on res except chaos), and anything else is just gravy. Anyone have any idea how I would go about crafting this? I already have an ilvl 85 shaper crystal belt. I currently use Ice Nova of Frostbolts in my main CoC link and Frostbolt in my Cospri's. I see a fair amount of people using

But wouldn't be shocked if I missed something, I threw together a very quick minimal POB:

Was bored and playing PoB. I've never played CoC, so there's probably flaws I'm unaware of. DPS seems low but its hard to tell what the aoe overlap will be like. Any thoughts/suggestions? edit updated pastebin update got bored and gave up on it. here's the current if you want it
