There are 14 playable classes in MU Online on current files — from the launch trio to Season 21's Crusader. This page compares them all in one place: when each arrived, what role it plays, which stat feeds its damage, how it unlocks, and which class to pick for PvP, PvE, solo play or a first character. Every class name links to a full guide with skills, builds, gear and wings read from our server's own files.

The complete class list
Sorted newest class first. “Damage stat” is the stat that feeds the class's skills; “Unlock” is what you need on the account before creation (on our high-exp server those gates are minutes of work).
| Class | Added | Role | Damage stat | Unlock |
|---|---|---|---|---|
| Crusader | Season 21 | Hammer-and-shield melee support | Strength | Free |
| Alchemist | Season 20 | Wand-and-elixir caster | Energy | Free |
| Illusion Knight | Season 18 | Agility blades, phantom twin | Agility (80%!) | Free |
| Gun Crusher | Season 16 | Ranged magic gunner | Energy | Free |
| Slayer | Season 15 | Short-sword assassin | Strength | Free |
| Rune Wizard | Season 14 | Mace-and-shield caster | Energy | Free |
| Grow Lancer | Season 10 | Lance-and-shield dual-pool | Strength or Agility | Level 200 char |
| Rage Fighter | Season 6 | Debuff brawler, HP-powered | Energy | Level 150 char |

| Fairy Elf | Launch | Archer-healer hybrid | Agility (bows) / Energy (heals) | Free |

| Dark Knight | Launch | The original melee, combo burst | Strength | Free |
Two names you may meet and will not find above: the Light Wizard and Lemuria Mage exist in the game files as Season 17 special classes — most servers, ours included, run the standard fourteen.
Best class for…
| If you want… | Pick | Why |
|---|---|---|
| Your first character | Dark Knight or Crusader | Forgiving melee, always in party demand, and the Crusader is the newest class with zero unlock |
| Solo farming | Dark Wizard (barrier build) or Gun Crusher | The barrier wizard hunts alone by design; the gunner clears fields from range |
| PvP duels | Dark Knight or Grow Lancer (Agility) | The crit Combo decides fights; the Agility lancer's speed and elemental scaling win long duels |
| Party play | Fairy Elf, Summoner or Dark Lord | Buffs and heals never go out of style; the lord's Command buffs make any party better |
| Endgame speed | Illusion Knight | 80% Agility scales into every patch — the fastest clearer of the late classes |
| Something weird | Alchemist | Homunculi fight for you and the Confusion Stone prints drops for the whole party |
The unlock ladder
Four classes are gated behind an existing character — a classic MU habit. The gates, and what it costs to clear them on a high-exp server:
| Gate | Class unlocked | On a high-exp server |
|---|---|---|
| Account character at level 150 | Rage Fighter | Minutes |
| Account character at level 200 | Grow Lancer | Minutes |
| Account character at level 220 | Magic Gladiator | Minutes |
| Account character at level 250 | Dark Lord | The steepest gate — still under an hour on our rates |
Everything else — including the three newest classes — is selectable straight from the character screen.
Class changes: 1st to 5th
Every class walks a five-step ladder (for example Dark Knight → Blade Knight → Blade Master → Dragon Knight → Ignition Knight), with the big gates at levels 150, 400, 800 and 1200. The wings climb with you — see the complete wings compendium for every tier of every class. The two exceptions: the Magic Gladiator has no class changes at all, and the Grow Lancer is the only class whose build genuinely forks (Strength or Agility, two damage pools).

MU Online classes FAQ
How many classes are in MU Online?
Fourteen playable classes on current files, from the launch trio (Dark Knight, Dark Wizard, Fairy Elf) to Season 21's Crusader. The files also contain two Season 17 special classes, the Light Wizard and Lemuria Mage, which most servers never enable.
What is the best class in MU Online?
There is no single best: the Dark Knight's combo is the classic PvP answer, the barrier Dark Wizard and Gun Crusher farm solo fastest, the Fairy Elf and Dark Lord carry parties, and the Illusion Knight scales hardest into endgame. Pick by how you play — the table above breaks it down.
What class should a beginner pick?
Dark Knight or Crusader. Both are forgiving melee classes with no unlock gate, strong party demand, and simple stat plans (Strength first).
Which classes need to be unlocked?
Four: Rage Fighter (a level 150 character on the account), Grow Lancer (200), Magic Gladiator (220) and Dark Lord (250). Everything else is free from the creation screen.
Which classes get 7 stat points per level?
Grow Lancer, Magic Gladiator and Dark Lord earn 7 points per level; everyone else gets 5. It is the game's way of paying the hybrid and gated classes for their slower starts.
What is the newest MU Online class?
The Crusader, added in Season 21 — a hammer-and-shield melee class that was also the first class to receive the Imperial Legendary tier.
Can I change class in MU Online?
Each class evolves through its own five-step ladder (levels 150/400/800/1200), but you never swap to a different base class — you level a new character instead.
