Meteo is the most powerful Spell in the game, but it's rarely worth casting. No one but Rydia can really spare the 99 MP, and she should have Baham, which is nearly as powerful but costs over 1/3 less MP. Plus, Meteo takes a very long time to cast, while all summon Spells are ready quickly. On the upside, Meteo certainly looks cool.

Only the final boss uses this Ability, which is reasonably powerful but no worse than some of his other attacks. While the basic Starfall Ability can deal anywhere from 70–280 damage per level, it is subject to the usual damage rules for multi-target Spells, leading to an actual total damage range of 175–700, mitigated by magic defense.

Meteor is a powerful attack Spell that deals non-elemental damage to all enemies. It's basically a multi-target version of Flare. However, by the time you get it, you'll have a Sage, who can cast the more powerful level 8 summon Spells, making Meteor instantly obsolete.

On the other hand, a number of enemies use Meteor against you to devastating effect. There isn't much you can do about it except keep your magic defense and HP as high as possible.
