I agree...he is very tough. Roll with invective, make sure invective guy is the jail breaker. 4-5 shots with invective. Stay close together. Have a gally or truth spam the middle, and another on boss. Have another guy roll with a good void heavy machine gun. Its difficult but not impossible :) Good luck man. I'll see if one of the guys I did it with earlier posted a video. It was a decent strategy.

The Prison of Elders was never meant to be easy. Try readjusting your strategy and maybe find higher level players? There are plenty of YouTube videos showing you how you can beat Qodron easily.
