Class paths
The original classes grow through quests. The 2nd class comes from Priestess Sebina and the 3rd class from Priest Devin, both in Devias. Magic Gladiator and Dark Lord skip the 2nd step and go straight to their 3rd class. The table follows the official guide; the Summoner row comes from the fan wiki.
| Start | 2nd class | 3rd class |
|---|---|---|
| Dark Knight | Blade Knight | Blade Master |
| Dark Wizard | Soul Master | Grand Master |
| Fairy Elf | Muse Elf | High Elf |
| Summoner | Bloody Summoner | Dimension Master |
| Magic Gladiator | none | Duel Master |
| Dark Lord | none | Lord Emperor |
2nd class: Sebina and the Scroll of Emperor
At level 150, visit Priestess Sebina in Devias (the fan wiki gives 183,32). For 1 million Zen she tells the tale of the Scroll of Emperor, the record of Muren, the first emperor who united MU. The scroll is said to turn up around the Lost Tower, Atlans and the Dungeon. Bring it back and she helps you unlock its power.
For a further 2 million Zen, Sebina sends you after the treasure your tribe once offered the emperor as a sign of loyalty. Return it to her to finish the quest and become a Blade Knight, Soul Master or Muse Elf (and, per the fan wiki, a Bloody Summoner).
| Class | Treasure |
|---|---|
| Dark Knight | Broken Sword |
| Dark Wizard | Soul of Wizard |
| Fairy Elf | Tear of Elf |
| Summoner (fan wiki) | Abyssal Eye |

Marlon's quests
Marlon shows up in Devias, Lorencia, Noria or Atlans. For 3 million Zen he tells you about the Ring of Glory, once worn by Emperor Muren and said to lie in the deserts across the sea. Bring him the ring to complete the quest and join the vanguard of the Continent of MU. The 3rd class quest needs this Marlon quest done first.
Blade Knights can then talk to Marlon once more. For another 3 million Zen he asks for the Dark Stone from the deserts; handing it in unlocks the Blade Knights' own power to chain their techniques together, something no other tribe can copy.
3rd class: Priest Devin's three parts
Every part starts and ends with Priest Devin in Devias (182,27). The Barracks of Balgass are entered through Werewolf Quarrel in Devias (187,27), and the Refuge of Balgass through the Gatekeeper inside the Barracks (119,168). The party leader must warp in first; party members above level 350 can then follow.
| Part | Needs | Task | Reward |
|---|---|---|---|
| 1. Certificate of Strength | Level 380, 5 million Zen | Bring three items; the fan wiki lists a Death-beam Knight Flame (Tarkan), a Hell-Miner Horn (Aida) and a Dark Phoenix Feather (Icarus) | Unlocks part 2 |
| 2. Infiltration of the Barracks of Balgass | Level 400, part 1 done, 7 million Zen | Kill Balram, Death Spirit and Soram in the Barracks | 10 stat points |
| 3. Into the Darkness | Level 400, part 2 done, 10 million Zen | Kill 1 Dark Elf (Hero) in the Refuge of Balgass, at the far end of the Barracks | 20 stat points and the 3rd class |
- A kill counts for the player or party that dealt the most damage to that monster.
- You can only enter while on the matching part. Party members who are not on that part, or already finished it, get no kills, but their teammates on the quest still do.
- You may hand in the kills you already have to Devin and go back for the rest later.
Tracking and what comes next
A later update put the Change Class quest description in the My Quests window (T) too, not only in the NPC dialogue. The newer Quest Journal, which tracks quests live, cannot hold the Class Change or Marlon quests. After the 3rd class, the next step is the 4th Class Quest; see Classes Overview for every class.
