[3.26] Shield Crush of the Chieftan Blackflame (Perfect Agony Double DoT)

Been enjoying this build and wanted to share it. I'm actively playing this and will make small adjustments where I can, when I'm able.

The primary skill is Shield Crush of the Chieftan, which scales fire damage instead of physical.

These uniques allow us to play with ignite and poison damage over time.
The Seething Fury unique jewel and Ungil's Harmony give easy critical strike cap, and let us scale these two DoTs through Perfect Agony.

I'm obsessed with Pathfinder, so I made the build on this ascendancy. PF's wither effect and wither on hit pair well with Blackflame, and the flask sustain let's us make up for missed defensives from heavy use of uniques. Additionally, PF plus any source of ignite proliferation gives satisfying pack clear.
Other possible ascendancies could be:
Assassin. Possible 100% crit without Ungils + Seething Fury combo, maybe opening a different shield than Emperor's Vigilance.
Occultist. Explosions, wither, and powerful elementalist nodes to steal.

That's the basics of the build concept.
Currently, I'm working towards level 100 and scaling it along the way.
My most recent addition to the build was: Which PF has an relatively easy time sustaining.
Settled on a sceptre craft. Still much better than unique alternatives:


My build is currently around 9-10m combined DoT. Next big purchases are probably a Progenesis, and looking to replace Cospri's Will with a rare chest.

Thanks for sharing, this looks pretty fun! Will try it out.
