Magician Ranks:

Beginner Magician ... Three Stars

Advanced Magician ... Four Stars

Expert Magician ... Five stars

Great Magician ... Six stars

Holy Magician ... Seven stars

The number of mana stars expresses his mana energy and not his rank, the sufficient number of stars with precise control of mana and the implementation of complex magic circles is what determines the magician's rank.

There are a lot of experts magicians with six stars but their rank wouldn't rise to be a great magician.

there are two magical spirit forms which are The Shaman Spirit Form and The Cleric Spirit Forms.
