In Esperia, there are many classes. The most popular ones are:

Mage (Standard)

Gunslinger

Sword Mage

Spear Mage

Protector

Holy Mage

Those are just the most basic Classes. The get to ranks like "Awakened" through cultivating normal classes is unlikely.

The Secret Classes are 10 times more effective than normal classes.

Because they are so powerful, no one wants to share these with the public. It's only passed down by noble families, who have obtained those from their ancestors.

The other problem is, that cultivating without a high ranked Master is likely to fail because the cultivating process is very difficult to grasp.

Speaking of Masters, they are high ranked, but nowhere near true Masters.

The Ranks for cultivating all classes are divided into those Ranks:

Beginner

Intermediate

Advanced

Master

Grandmaster

Awakened

Elder

Special Rank: Special Force – HOPE

All Soul magic users will begin as Beginner. Through cultivation, hard work, experience, and luck, they can advance in Ranks.

The ranks are universal and apply for all Classes.

Advancing in Ranks means, that ones Magical Power will increase.

One will be able to wield stronger Magic and the stamina will increase.

The bodies will change into Celestrial bodies after breakthrough of the Grandmaster Rank.

The Special Force Rank is for the most gifted ones. Their strength is matching with Elders, some are even stronger!
