Spell... hm, I'd say my curative spells and Ultima, Holy, Flare and Meteor. Summons... Bahamut, Cactuar, Tonberry and Alexander. Only trouble though, I need lots of energy for them all, except my curative spells. So, I end up exhausrted when I use them too often in a battle.
*notice the time*
I guess you want to get back to the apartment and sleep, huh?
