The encounter still has a lot of bugs and RNG CAN screw you. I really believe there is an element of luck to doing this quest. But what worked for me was:
905 ilvl, 47 or so artifact traits (I think, been a few weeks now)
2 Thrash relics, 1 UE
Luffa + Elize's
Horn of Valor + Fang off Tich
Bear Tartar + Agi Flask
Incarn, Bash, and Bal affinity were the only changes I used over my normal setup
Pulled Inquisitor to Velen, used Incarn + RotS and pretty much never set foot in the death and decay aside from when I was interrupting. Just used Thrash, Swipe and Moonfire. P2 NEVER STOP MOVING! It's annoying and one wrong button press or mistimed interrupt/movement can kill you, but it can be done. Good luck!
