Low Level Mages (Level 1-3)
People with pink and yellow auras can only become low level mages.

Intermediate Mages (Level 4-7)
 People with light green and green auras can become intermediate level mages. Most mages in the Lower Realms are low and intermediate level mages.

High Level Mages (Level 8-10)
 Blue and purple auras can become high level mages. However the potential for the latter is much bigger than the former. For example, the purple aura, its potential is much more than the blue aura. Therefore there is hope of becoming a top level mage. High level mages are hard to come by in Long Xiang continent.

Mages, especially higher level mages, enjoy great prestige because of their ability to refine higher level miracle pills. Therefore, high level mages have always been the target of big-name sects.

Transcendent Level (Level 11-12)
Introduced in the latter part of the Long Xiang Arc is Rainbow Level. It is also known as transcendent level in LongXiang Continent. Rainbow level is divided into 7 grades: one through seven. The grade is determined by the number of colors that the soul radiates. For example, a mage with a 3-colored soul has the potential to be a Rainbow Grade Three mage. A 7-colored soul has the most potential and is the most rare.

Due to the natural restriction placed on Middle Realms, mages are unable raise their aura beyond level 10 (purple).

There are more mages with rainbow souls in the Higher Realm, since there is greater spiritual energy and no restriction; however, the grade they are born with still varies. Nonetheless, rainbow mages can still train their soul to reach higher grades.

A Grade 4 Transcendent Mage is equal to a 1 or 2 star Sacred Realm Practitioner (Ch 657)
