PoE builds similar to Vacuum + Molten SHELL (69% meme build) - Path of Exile (3.15 Expedition)

This build revolves around running around with reverse knockback cyclone, blowing things up with Molten Shell, triggered with reflected damage from Hiltless and Defy Pain. Transcendence is necessary, because otherwise, a pathetic ~7k phy hit from defy pain would only tickle the molten shell. In PoB, this build is near-immortal with enough damage for end-game content.

I have been playing a Pathfinder, Caustic Arrow Ballista poison build for a bit now and I am liking it a lot.

The build in question: Thanks for you time. &x200B; 1st edit. forgot to mention that the items are not optimized at all. I just pretty much took items that gave the most dmg/ werent the most stupid items of all time.

Which build would be better as a league starter? I'm leaning towards Hot DoT Trickster but I'm unsure if totem health will be an issue. Gear in both is a filler so don't be concerned about not being resist capped or not having sufficient attributes, though I am intending to use their bases.
