maybe your on level five so u cant level up anymore because thats as high as u can level up a form

you need to get your drive at lv 7 to level up wisdom kill a heartless it will give you 4 exp best place is world that never was and to level up master form you need to get big orbs best place land of the dragon (mulan) and fight alot of horseman things I got 10 exp for every big orb

maybe somone smashed there game one to many times ummmmmmm!!!!!

Master Form gets experiance by collecting drive orbs. Final Form levels up by defeating
nobodies.

Master Form gets exp from drive orbs (not the ones in ur items) best place Land of Dragons
Wisdom Form gets exp from killing heartless best place The World that Never Was
