BTW how do you defend against non-elemental Magic? Last job boss is destroying me.
Dark Knight's Absorb Magic - Nullify damage from magic during that turn and restore your MP by the amount of MP used to attack you.
Spiritmaster's Stillness - Neither enemies nor allies suffer damage for 2 turns.
Other than that, M Def raising abilities help. There are probably more options that I am not remembering right now.
P.S. -
IIRC, all I did in that battle was dispel him everytime he used a buff. He'll usually then cast the buff again in the next turn, and not bother attacking. Re-raise on your party members also helps.
