Great Weapon Fighter.
Lv 70 equipment = Blue weapon and green gear, no shirt/pants.
No artifacts, no enchantments, no augment ioun stone.
Every boon unlocked.
I died 3 times, unfortunately, I went inside too confident and unprepared because I was too used to run it in 2 minutes with all my BIS gear and I never realized how strong would be this mobs hitting a character with very bad gear, however, Biggrin was killed in the end.
