Usually I use the mono-elementals till I get all the Djinn and really can play around with them, but otherwise it's like:
Isaac - Ninja
Garet - Samurai
Ivan - Sorcerer or Guru
Mia - Oracle or Angel
Felix - Ninja or Dragoon
Jenna - Flame User or Pierrot
Sheba - White Mage
Piers - Dragoon or Admiral
THAT'S FUNNY CAUSE SYLVIA AND CLAUDE'S OFFSPRING HAVE NOT YET APPEARED That's what I thought.
At least Corple was mentioned, so he'll show up soon.
'Course, then we'll be trolled and Sharlow and his Berserk staff show up.
So I'm catching up on the manga and first I see Fee being jelly, and now Leaf's body being ready. >_>
Also I think TE translated something back a few chapters that had Arthur use Elfire, so that might mean AzelxTiltyu.
