Psh...this guy was the hardest one to kill for me. Even with a thief's ring (which I never took off on my Thief class person). The dude never let up and every time he would chase me all over the fighting area. No matter what I try on any of my characters, even range...he'll just charge in, he isn't "blind" at all for me. I've had to melee fight him always, while dodge rolling like a maniac.
