To add to what Trumpy said, if you have a chocobo wand or any other event weapon with 1 damage, that is great to use for tp feed. It also won't hurt your spells too much as long as you have a decent club skill.

I also learned body slam after zoning to drop hate while the rest of the party kept fighting it the dragon. I zoned back in, saw it die, and got the spell. So just another example of learning under an unusual circumstance.
