I run it with SK with about 8K ac and 400k hp's. I don't glyph, just shield flash at the start then pop cursed guardian or resteless mantle and let the healer do it's job. Having good dps helps a lot on this event, I'm still working on that lol. I don't get 1 rounded at the start, though and I am able to kill it before getting rats now so that helps. He does hit like a truck.
