Grand Magister Devon:
To become a Shillien Oracle, the appropriate level and token are required. Your level must be at least 20 to qualify to change profession. Also, a token that proves you have passed the Test of the Shillien Oracle is required.
It seems that you admirably passed the Test of the Shillien Oracle, but your level is not high enough. Level 20 or higher is required to change profession. I cannot allow you to change profession if your level is not sufficient, even if you have a token. Come back when you have raised your level.
