No it’s amazing and so is Micolash. The arena you fight him in changes, so after he flees you want to run out the door and head up the stairs. There will be a new doorway on the top floor that leads to a staircase. One path takes you to some loot, the other takes you to a new area where you’ll find Micolash, who will try to run away from you. You’ll need to chase him into a corner again to be able to finish the fight.
