For those complaining about the MP limit, at that point in the game it would be too easy if you could go around liberally using every spell he has, especially Meteo. They had to do something to limit your use of the most powerful spells, so personally I think him having only 90 MP at least kept things from being too easy. Although you can still kill a guy like Kainazzo with one spell, so you can't complain that much. Aside from that, Tellah is an awesome character. One of my favorite in the FF series.
