Gold Stud and spam Luminaire?

I usually don't have Luminaire at that point of the game, I always seem to get it at the Zeal Palace. I am too lazy to grind...
But I DID manage to defeat Giga Gaia once with Water 2 and Marle spamming heals, Crono doing damage.

you can knock out ~130 tech points easily on mt. woe near the save point. one of the rubbles will always respawn. you can max out everyone's techs in about an hour.

I usually grind at the Zeal Palace. And I kill monsters on Mt. Woe until I get Falcon Hit.
