So they went with the Black Belt. As I said, I would have gone with the dragoon personally, or maybe a summoner. Maybe the Black Mage was having magic envy. Didn't want anyone else more powerful than him in the group.
Red Mage isn't much a threat. I mean, they're great characters to have in your party early on, but the limits of their character become quite clear late in the game.
 
    

When evil spreads across the land, and darkness rises and the monsters roam. When the creatures of the night make beautiful music, and the things that go bump in the night go bump with greater enthusiasm. When the world is in peril and is in need of a hero...

These guys are, sadly, the best the world can hope for. These are the adventures of the heroes of CVRPG. They mean well, they try hard, and occasionally they do the impossible...

They actually do something heroic.
