How classes work



MU Online has 16 classes, each with its own powers and items. As a character levels up and finishes class quests it evolves into a stronger form. Every class change opens new skills, weapons and wings, and changes how the character looks.
The game was built around three original classes that are meant to work best together in a group, so no single one is simply the best: the Dark Knight fights up close, the Dark Wizard casts attack spells from afar and the Fairy Elf uses bows and support magic.
Starting and unlockable classes
Older guides split the classes in two groups. The Dark Wizard, Dark Knight and Fairy Elf need no level to create. Other classes became available later, once the player had a character at a certain level. The older community wiki gives these examples:
- Magic Gladiator: unlocked when a character reaches level 220.
- Dark Lord: unlocked when a character reaches level 250.
- Grow Lancer: needs another character of level 200 or higher.
- Summoner: added in Season 3 and could be made as a starting character.
Your class also decides your first town: Fairy Elves start in Noria, Summoners in Elbeland and all other classes in Lorencia.
