@Cyringohn:
Zidane also had Stellar Circle 5 [or whatever it was called], which also did 9,999.
Really? I don't recall ever getting more than 5,600 damage out of any of his Trances.
I didn't bother with Thievery simply because it took too damn long to do anything with it. Maxing out Dragon Crest by killing Grand Dragons is one thing, but maxing out Thievery is something else entirely. Same for finding the Spirits, I eventually just said to hell with it and took Ozma down without them.
Ozma opened with a Doomsday that backfired on him and dealt a couple thousand damage to him. For the first turn, I had Steiner use Shock, Freya use Dragon Crest, had Zidane Trance, and had Dagger use Ark. Second turn, Shock, Dragon Crest, Zidane threw a Dark Matter, and Ark. Much the same the next turn, though Zidane got killed and did nothing. Two turns later, Freya was the only one standing after a Curse, so I had her Dragon Crest him. Badda bing, badda boom, bada dead Ozma. That alone shows how epic it was as I can still remember that single battle years later.
