Yeah. You can get H.P spheres from ironclad, but he takes a while to fight. My main party has 40,000+ h.p. but you only need 9999. I made a mistake back then.

As for other things to do, unlock nemesis, build everyone else's stats, fight the dark aeons and penance, power up celestial weapons, get secret aeons, etc. I've done everything (except dark aeons. I have the ntsc/uc version so I can't) that I listed, so I'm pretty much screwed. The game is boring now.
