PoE builds similar to 3.19 Elementalist Golem Build for Endless Heist

I found one on my first char and wanted to see if I could do something for the event, but I'm terrible at creating builds. I went away from Templar because I don't think crit is particularly easy to gear, so I wanted to try Chieftain with CwC fire conversion (PF trigger, WoC in weapon). DPS on this is like 400k and defenses are nearly non-existent. I could go glancing but would need a life on block shield I think. Any thoughts (including "this is terrible please stop") is appreciated.

My guess would be Inquisitor, Righteous Providence (as first node) and using Cyclone with a dagger with +8% base crit. Back in 3.14 (before CoC used mana to cast spells) I played LL Purifying Flame Inquisitor with the above setup and I remember it was perfectly functional very early during campaign. Now with the mana issue I don't know. This was my PoB back then, in case you guys can see something useful from it where I don't.
