PoE2 0.3: Twisted Domain clear and Xesht kill (Tier 3 - max) with Bonestorm Lich

Technically I'm an Abyssal Lich but since I'm not using any of the modified nodes (one explicitly doesn't work with Bonestorm and the other two are kind of underpowered as far as I can tell) I didn't put it in the title as it'd be a bit disingenuous. First T3 boss so I was probably dodging a few things I could've tanked but well, one portal makes for a cautious player. This build kind of excels at this type of content though, compared to something like Simulacrum where you get swamped too easily.

PoB : https://pobb.in/2KPXBdHgsRXx although quite a few things aren't working yet for obvious reasons, in particular I don't think the Sigil of Power weapon swap is taken into account. And on the other hand the Soul Offering is permanently active whereas I'm only using it during bossfights.
