I second that. I tried 7 (yes, seven) times completing this quest, I got hitted for insane amount of damage. It is not just the last boss (some shaman) before him there is a big group by one elite mob + 6-7 normal ones, all hitting like crazy. Example – two hits 3K + 2K in a row, dodge that. Is this a some sort of a bug or it is working as intended ?
