Abyssus with PB, 2.5k hp pool, and 0 armor build that is actually tankier than any 6k hp Champion with 500k armor and fortify. Yup, you read that right. Slayer leech is insanely strong.
That's the direct PoB from my current character in league. Is geared towards clear, can handle 100% deli without dying, just keep moving. Need to swap out a couple items for bossing, by which I mean Ubers, every other boss dies in seconds. Flask uptime is near 100%, you need those exact mods on the flasks.
Can swap chaos flask for Bottle Faith for Ubers - Needs a bit more investment to comfortably handle Ubers, but doable in this state with good mechanics.
Overleech is almost entire life pool regen, lasts 10 seconds. As long as you're hitting shit, you're not going to die, that includes DoTs. That exact life flask is 100% hp near instant recovery + 400 additional regen for 10 seconds - after flask ends.
The only expensive shit is the Replica Farruls and the Massive Thread of Hope.
Everything else you see was under 5div, at least it was when I got it. Shield and boot base were 50-150c, crafted with about 1div in rerolls each. That reduced ailment duration implicitx2 makes you ailment immune to everything except chill/shock ground.
If you can’t find shield base with reserve implicit just drop Precision.
I see a lot of Archnem complaints but this build has yet to fight a Archnem rare that lasts more than 3 seconds.
Can do all map mods but less recovery and no regen will make you really squishy and instagib to dots.
As geared it's about 15 million dps, if you could fit in Tailwind/Elusive/Onslaught boots and Ryslatha's Coil it could probably hit close to 25-30 million with the right setup and be super fast. You could also man up and put on an Arn's Anguish for even more DPS but you will die to the softest physical touch.
I’ll post a more in-depth guide and video if there’s interest.
