Just did this fight on Duty Finder, Just queue with the Japanese people they all know the fight, it was my second time and I don't even know the boss mechanics or rotation, but I dodged everything cause I'm constantly moving (bard) quite simple fight really.
We only died cause we didn't know u had to leave the person in the gaol or you will hit enrage for the heart. I'm not even in Full darklight, if you are finding it hard replace rings and earrings with tank ones cause it gives vit. It's a survival fight.
