Help, I how do I change my elite class?

[solid elm]

I need help beacuse I did not played the game for while and when I got back at it chose for my 3rd warrior to be berserk instead of divine knight. Do you have ani sugestions?

P.S. I bought the class changer but I does not work for elite classes
