Actually, I just beat it yesterday (with all the scrolls, to boot). Though that final Boss sure puts you through your paces, huh? Not only do you have to beat him FIVE times, instead of three, but you have to completely flip-flop your tactics. While the other Bosses, you can basically just charge in and fight smashmouth, with THIS guy, you have to be hold back and let HIM come to YOU all the way.
