So I decided to try and solo this bastard to get access to oblivion mobs, and after three deaths decided it was impossible when he damage reflects. The buff is activated the second the animation starts, and damage reflect is a one hit kill for a mage since it bypasses magic gaurd; in other words, the second it hits 50% HP it's just a matter of time before I drop dead, unless I stop attacking. Is there any strategy to soloing this guy, or will I just have to find a party?
