What mythological creatures haven't shown up in berserk?

[Aazealh]

Not only Ganishka, Daiba and the others Acolytes(the ones who control the pishacha) cold be considered as wizards.

Rather low-level ones then, considering how they derive the little power they have from Ganishka. It's not what cajunman380 was talking about when he mentioned a battle against a full-fledged sorcerer.
