Peter_20: Ultima is pretty much useless, it will do very low damage unless it's the DoS version and you've leveled up really much. Even then, I think Holy and Flare will do a lot more damage even on lower levels. As for your spell list, you forgot Blink (good defence together with Safe and Shell), Curse (greatly reduces the enemy's attack and defence) and Toad (instant kill if it hits). For leveling up purposes, Anti/Sap is a good spell for increasing your max MP (cast it on your own characters to drain their MP), and if you feel like it, Change can also be useful.
