Grand Master Rivian:
You need the appropriate level and token to become a Human Wizard. To change profession, your level must be at least 20, and to become a Human Wizard, you must have the token that proves you have passed the Test of the Human Wizard.
You have achieved a sufficient level, but it seems you have not yet passed the test. You will be accepted as a true Human Wizard only when you have passed the test. The Test of the Human Wizard requires gathering the tokens of the four elements. Visit Parina in our sanctuary to learn more about collecting the tokens. To change profession to become a Human Wizard, you should bring back the bead of four seasons which you will receive when you have all four tokens.
