welcome aboard ArcticaFrost.. i'll add you.. but wow.. you got good characters there..

i don't know if these will help you.. but try go to this link, the picture will explain how to get to the next Advance Class.. if i'm not mistaken from what i learn.. if you want to be Sentinel, you need to have level MAX class of Knight & Priest.. so you can unlock it.. same goes with the other class.. it require 2 class to open the next advanced class + it need CP (here's about CP )

good luck anyway.. hope you enjoy play it.. btw there's new event right now..
