Empowered Imperial Consular doing too much damage

Got this boss on TG today layer 8 floor5. Can’t kill him. No matter what I try nothing works. Wasted my time…

My wife and I just ran Twisted Corridors Layer 1, got this boss on floor 17 and it one shotted both of us on multiple tries. My wife is BM hunter ilevel 200 and I was on Prot PLD ilevel 197. On the last try I was one shotted with a sin bolt for over 70k…wasted 2.5 hours to get there. WTF :skull_and_crossbones:
