Mostly bosses from rental titles, but though I never played Lunar 1, if he's anything like Zophar in Lunar 2 anyone who complains about either of them is justified.
1st phase is pretty simple, but it's obvious he's got to have more than that. 2nd phase always kills me; Not only must you sit through tons of dialogue while an invincible Zophar pounds on you and you can do nothing but heal, after the real fight starts it's not much different. He has 1 head and 4 hands, each with their own powerful attacks and more HP than the 1st form apiece. Some FAQs I read suggested a suicide run at the head but that never seemed to work since the hands prevent physical strikes on it besides Poe Sword and some of Leo's stuff. He also gets 2 different insta-kill attacks, one of which is only used after 10 rounds or so (the laughter). Either way, there's not much you can do if he insta-kills Ronfar enough times so you run out of revive items (to be fair, I was only Level 56 and didn't have the items to grind any higher so maybe being Level 60+ helps). I only ever managed to kill 2 of the hands at best before either running out of revives or simply getting overwhelmed by all the damage. Great music though.
Apparently he actually has a 3rd phase you fight with just Hiro and Lucia as well, which is equally difficult.
