Yes, I killed this morphing pain in the you know what solo at level 23 with my Barbarian. It took a few times, but I readjusted some of my skills, and he became a piece of cake to kill. I never even had to use a health potion the entire fight All I can say is spam Ignore Pain, and Threating Shout every time the cooldown is done. I will show you screenshots of my skill setup that made it real easy to kill this boss in Diablo 3.
