Huh? The download link on this site

Anyway, it turned out I could get Ultima spell out of the Magic Pot in the Lost Lab. However I was not too lucky, and I had to spend at least a hundred Cryna Orbs or so, just to get one Ultima spell. With Ultima spell, Atlas Dainsev, and Flare spell, I was able to defeat Paradorn, both the first and the second form. So, I guess I completed the game, except that I still cannot defeat Watcher Omega. Heck, I did not even have a chance to try it. Watcher Omega strikes first, and with just one swipe of Ultima spell all my characters are gone.
Has anyone ever defeated Watcher Omega? The strongest character in my party is Deren, and he only has about 400 something HP, while Watcher Omega's Ultima spell strikes at about at least 600 something HP. It feels rather boring just training again and again to get higher HP, especially with a rather strange HP levelling system like that.
