PoE Mjolner builds without The Ivory Tower

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.

How the build works: 1. Arc in Mjolnir for clear - hits 6.06 times a second for around 1mil dps 2. Ball Lightning CoC in chest - calculation is average hit 6.06 11 3. Very tanky with nearly 9k HP pool, fortify, close to 2k regen, and the big thing - x4 surging vitality cluster notables regening 4k effective life every 5 seconds thanks to Pious Path. Can ramp up the damage to crazy levels with the following if you have the budget: 1. CDR boots and 7.5 attacks per second 2. Bottled Faith 3. Divergent Ball lightning 4. Watchers Eye 5. Min maxed gear 6. 20/20

Sup yall, I'm thinking about staring a series on builds created around underused uniques. My first choice was Volkuur's Guidance - gloves that causes elemental damage to poisons on hit. Here is my work-in-progress showcase: Here is PoB: [
