Have you tried to defeat him with friends because i have and it doesn't help and I'm always on the the falmea realm or the ambrose realm we should try to defeat him together. My wizards name is sabrina ashtail and i'm a level 36 fire wizard want to work together and try to defeat him on the falmea realm this sunday around 2:00pm?
I feel it's easier to defeat that dungeon with two or more friends other than you. Me and a couple of friends teamed up and go to grubb, however we had to leave before we could beat him. Now I have to start all over for some reason. I wish it would save your progress.
