# CLASS EVOLUTION

Unlock the full potential of your characters in MuOnline by completing the essential class evolution quests. Advancing through these class upgrades allows you to gain powerful new abilities, increased stats, and access to exclusive gear, making your character stronger in battle. This guide provides detailed instructions for each class’s upgrade quests, led by the legendary NPCs Sebina and Marlon.

## 1. What is Class Evolution in MuOnline?

In MuOnline, every character starts at the base class, but through class evolution, they can transform into advanced versions with enhanced stats, skills, and equipment. To evolve, you must complete specific quests that challenge your strength, endurance, and knowledge of the game. These quests are designed to test your character’s abilities and prepare them for tougher enemies.
