Ok so it was me Jabba and Cornholio at the_keep when we got to the boss nova blader spawned. I started dsing it doing 200-250 Jabba was DCing it and cornholio was taking out archers. After awhile it was still green bar barely goes down. So i use my hoarfrost it goes down a bit faster and then when he gets to red he pots.... We get him to red 2 times and he pots everytime and then Jabba quit after that. He also killed me in 1 hit when i have like 500 hp left. I think thats a pretty overpowered boss he shouldve died a long time ago.
