Recently finished FF9 again. This topic reminded me of the cutscene I recently saw.

Agreed - Ultima is Black magic. If your saying it's White, then it certainly is one bad-arse white magic.. Especially for pretty much the most badarse character in FF9 (Which is one of the many examples)

comet and Meteor where time magic when a time mage existed

I wouldnt mind ultima.

But Make it so that the spell is linked to the weather. Like almost a uberhelix. We can change its power to suite the need, giving us a nuke for every occasion.
