It was almost like asking.

There is a use for it, actually, since you can get Ultima with the Paladin Sheild.
That requires a lots of time, though. Since you'll have to kill 256 enemies, with the Cursed Sheild equipped, in order to get the Paladin Sheild. But yeah... it probably WILL be worth it though, as double-casting Ultima is pretty sweet, not to mention the Paladin Sheild is the best sheild in the game.
Edit: Oh crap! I forgot it was "natural" magic, not just "no esper".
I would be impressed........ if you hadn't used a guide
