I collected enough xp to fill xp bars up on the three charactrs i have but can't seem to work out how to level them up ?

Unless I'm missing the obvious, My xp bars are full to the point where none can collect anymore. How do you level up? It states nothing in the manual, just that it's something you should do. Well that's nice. Mind telling me how?

I was wondering the same thing. Cant work out how you suppost to level the characters up.

They'll auto level once you finish the chapter. Could've put that in the manual.

Actually, they level up immediately once the XP bar is filled. It's just that their "stats", attack and spell power, increase gradually with XP gains, so you might have missed it. The only real way to notice is that their Max HP jumps up significantly once reaching the next level.

But you can only level up once per stage, preventing you from becoming too powerful too quickly.
