I'm stuck on him, with 5 stack so I don't want to mess with skills to make it easier, I'm having trouble even making it passed the mobs at the start. If anyone is willing to hop on quick and help that would be much appreciate.
I'll be at home in about 20 minutes, then I can try to help you. I can solo him but never tried grouping, but I'm willing to try anyway if you don't find anyone.
What class are you playing?
edit: I'm a melee wizad and I usually kill him by the third green phase.
