I was doing the Khaziel quest line and after you fight Gorg the first time I know I saw like three more chains in the quest but it’s telling me there are no more quests. How can I fight Evolved Gorgotha?
Have you completed the Adana quest line? You need to do that too (or at least part of it?) to unlock the Mega Gorgotha chain.
That must be it. I did the 1st quest of Adana and it unlocked more quests in Khaziel. I wish it was more transparent what was wrong ingame
