I am looking for advice on a good strategy for dealing with the end guy, Barnzidu, in this quest. We've completed it, but it's just not pretty. What strategies have people found to be good, specifically when combating that soundwave thing, or whatever it is that does the massive damage to everyone and curses them at the same time. It really ****es off our healer, and given that he's my husband and it's supposed to be fun, I am looking for some advice.
Party makeup is different from time to time, but our group is a "play what you want" type. The rest of the quest is cake. Any constructive advice that will scale with difficulty would be helpful.
