Looking for PoB or just tips on non Armour Stacker Molten Strike/MS of Zenith build

I'm done with my standard and private league HC characters, just need to do 15 more challenges on SC

So I want to Play something interesting on SSFSC decided to go with Molten Strike, but not sure what would be optimal strategy for Elemental Molten Strike build

I though that Slayer would be Perfect but I've seen some Warden Molten Strike builds on internet and I don't know now who to make. My guess would be Slayer as it's probably easier to gear and be tanky, while Warden on SSF will be glassy af with okay DMG

At the start it's Precise Technique Trinity, and probably change into Crit around maps right?

What weapon base would be best? For Zenith it would probably be the 2 hand Heist base that ignores resists on crit unless its not lol

Any tips or maybe PoBs if someone decided to Play non stacker version of MS
