Do Warriors become Knights? Mages become Wizards? I am almost at level fifty and they have not changed. I am playing The new FF for GBA.

Oh, you have to go through some Castle to get the Rats Tail, then you have to go to bahamut in a Cave somewhere and booya. Class change.....

check gamefaqs

They don't level up by their level. you have to go somewhere...look it up online or somewhere

You have to go to a castle and get a rats tail. That isnt hard but getting to the castle is as there is only a little bit of land that the airship can land on then it is a LONG walk. Go to Bahammut and he will upgrade u all. Bahammut is in one of the caves that just look like big holes in the ground.

It was calld the Castle of Ordeals in the FF for the NES not sure what it is now.
