yeah......................................................................................his clones suck they kill my monsters in like 30 seconds in real life (sigh)...........
To be honest, even though it's been a few months, I don't remember how I beat this boss. Just make sure you have plenty of high stamina + health food, use the best sword you can craft and armour. I think I was around level 80. I didn't use any monsters in the fight and I think I beat him first go. Good luck.
