I tried soloing him as a 49 shaman. I pulled him and only one of the other wolves followed. When I gated, black dire remained where I pulled him and the other wolf pathed back. Malo and root land fine, but I gave up after deciding he was more or less immune to poison/disease.
I tried again at 54. Solo pulled him this time. Despite being light blue, he's still immune to disease. I hit him with Turgur's insects, and let my hasted pet kill him. After a few heals, I have my pelt.
