A while ago I was doing the Cerberus Vae III Strike, and got REALLY tired of spending like four or five minutes or whatever slowly whittling down his health from fairly safe vantage points around the room. So I got up in his face with my shotgun, used my Fist of Havoc, flew up to avoid most of the blast from his stomp attack, and ended the encounter faster than I've ever personally seen it done before. Now this probably isn't a world record or anything, and my performance in the video wasn't all that great, but I actually hadn't attempted to do such a thing before and I was rather surprised how effective it was.
