King of the myst bug

My hardcore character level 61 died to King of the Myst cruel beeing like 20 levels over him. I had almost capped chaos res and I took zero dmg all fight. When he went to secound phase he one-shoted me for no reason.

I am making this thread either for GGG to explain this stupid boss or fix the bug. Maybe I did something wrong? Anyway a level 61 3khp str stacking character with almost max chaos res should not die to a lvl 40 zone boss.

You are forcing us to not even do the quest at all.

I got one shoted too at the king of the myst, on normal. I am lvl 13 and the boss is lvl 11. This boss definitely has a bug. Now I cannot progress because of this bug.
