I tried to solo it as a 72 ranger. I used drifting fog to keep the others from training. He summons frequently and casts. Hits for 400-850. It's snare, root, and slowable which helps.

Not sure what spells you were getting hit with, but I was being hit with Necro spells. Insideous Retrogression and Dooming Darkness, just to name a few.
