This guy legit took me longer to beat than any of the actual bosses, but that's mainly because of the time of the game during which he appears. Even when you get a stealth blow off, he has a fat vitality bar, fat posture bar and nasty combo's with long reach that absolutely **** you up when they connect. Blocking doesn't really help because he plows through your posture like a madman. If you dont deflect and respond to his perilous attacks properly, there's no chance in hell that you're beating him without cheese.
Though I must say: Nothing felt quite as good as revisiting this guy when I had more practice and realizing that he had become easy.
