A Mana Core is the crystalization of mana within a Magic User's body. Once a Mana Core is formed, a person becomes capable of using magic by utilizing the power in their Mana Core.
There are 10 known stages in a Mana Core's growth, also classified as Grades.
Each Grade represents the maturity of the Mana Core, and how much magic it is able to use.
Refining one's Magic Core and ensuring they break through to the next grade is one of the major occupations of Magic Users, since their cores can hold more mana depending on the grade, allowing them the ability to use even greater magic spells.
THE MAGIC CORE GRADES ARE:
Grade 1: White
Grade 2: Yellow
Grade 3: Blue
Grade 4: Green
Grade 5: Orange
Grade 6: Red
Grade 7: Purple
Grade 8: Silver
Grade 9: Gold
Special Grade: Multiple Colors (Rainbow)
Note: The White Core Grade is the beginning of a magic user's growth, and it usually ends at Grade 9, though those who have achieved this are rare.
The Special Core Grade is one which is only found in those who possess exceptional and godlike talents, and it is said that their mana pool and magic potentials... are endless!
