Hm. I remember him doing just as much as my Thief, if not a little more. At any rate, it was a bunch more than any number of Black Mages. And I remember using Black Magic less than, say, ten times in the entire game. Maybe 2 or 3 Bolt somethings on Kraken. So, I figure the total damage my Red Mage dealt is a whole bunch more than I would've had a Black Mage do.

Depends on style, I suppose.
