Janemba and other Sprite

[GoblinCutthroat]

If you open the spell list inside the client, it says that Janemba can do the Demon Death Ball, which make sense since he's a demon actually.
Then you try to do it and it says that your vocation can't do that spell seems like it's only for Shenron's, too bad because this makes Janemba the only(?) i think vocation that dont have the spell before the last one which in his case is Super Charge.
