Class evolution
The four evolutions, the real requirement of each one and what they actually unlock on the server.
Updated on August 10, 2026You create the first generation and reach the fifth through four evolutions, all of them by quest. The first two happen before level 400 and use the normal level; the last two use the total level, which is the level plus the master level. No evolution is optional: each one unlocks a system the previous one did not have.
- 11st to 2nd
Level 150, with Sebina in Devias
- 22nd to 3rd
Level 400, with Priest Devin
- 33rd to 4th
Total level 800, three trials against Cent
- 44th to 5th
Total level 1200, with Eunice
First to second class
The first evolution is the Treasures of MU quest, with Sebina the Priestess, in Devias (183, 32). It asks for level 150 and charges 2,000,000 zen to accept. Before it there is a warm up quest with the same NPC, Find the 'Scroll of Emperor', which also asks for level 150, charges 1,000,000 and gives 10 points.
| Class | Item the quest asks for | Where it drops |
|---|---|---|
| Dark Knight | Broken Sword | monsters level 62 to 76 |
| Fairy Elf | Tear of Elf | monsters level 62 to 76 |
| Dark Wizard | Soul Shard of Wizard | monsters level 62 to 76 |
| Summoner | Eye of Abyssal | monsters level 62 to 76 |
- Reward: 10 stat points and the evolution into Blade Knight, Muse Elf, Soul Master or Bloody Summoner.
- What it unlocks: items and skills marked for second class, and access to the quests only a second class can take.
- It opens Gain Hero Status, at level 220, with Marlon: that one gives +1 point per level forever and is the most valuable quest in this range. Only the Muse Elf gets a skill along with it, Infinity Arrow.
- It opens the Blade Knight combo, through the Secret of the 'Dark Stone' quest, also with Marlon, at level 220.
To the master class
The evolution into the third generation is the biggest turning point in the game. It is the Into the 'Darkness' Zone quest, with Priest Devin (Crywolf 228,48 or Devias 181,35), it asks for level 400 and charges 10,000,000 zen. What it asks for in the field is simple: kill one Dark Elf.
The hard part is getting to it. Before it come two mandatory quests with the same NPC: Evidence of Strength (level 380, 5,000,000 zen, requires the Flame of Death Beam Knight, the Horn of Hell Maine and the Feather of Dark Phoenix) and Infiltrate The Barracks of Balgass (level 400, 7,000,000, requires 20 kills of each of the three Barracks monsters).
| What the evolution unlocks | Detail |
|---|---|
| Master level | Experience above level 400 starts turning into master level, which goes up to 1100 |
| Master skill tree | The tree on the A key, with 400 points and three roots |
| The 13 Season 20 base skills | Handed out for free on the spot, filtered by your class |
| The Season 20 attack skills | Bought by orb at the Skill Master, requiring level 400 and third class |
| Mastery gear | The first tiers of the top end weapons and armor |
Third to fourth class: the Cent trials
This is the most laborious evolution in the game and the only one with mandatory boss combat. There are three chained quests, all with the NPC Cent in Lorencia (126, 143), all requiring total level 800, and none of them charges zen.
- Trial 1Eligibility Test
Defeat Cent in his test version, who fights with three of the six skills and no escorts. Reward: 20 stat points.
- Trial 2New Battle
Kill 5 of each of the three Deep Dungeon creatures (Skeleton Warrior, Larva and Cyclops) in 5 minutes. The waves refill every 5 seconds, at most 2 at a time. Reward: 30 points.
- Trial 3New Battle (2)
Cent again, this time with all six skills, 30% stronger and with escorts. Reward: 50 points and the evolution.
The arena
| Item | Value |
|---|---|
| Map | Trial Area (number 121) |
| How to get in | Accept one of the three quests with Cent, or use the Trial Area warp, which costs 0 zen |
| Instance | One arena per party. What happens in yours affects nobody else |
| Maximum players | 5 |
| Time on the boss trials | 15 minutes |
| Time on the wave trial | 5 minutes |
| Dying | Does not cost you the attempt. Talking to Cent puts you back in the arena |
The boss
Combat Cent is a level 160 monster with 1,000,000 health, 1750 defense and damage from 2600 to 2800. He has six skills: Fire Slash, Twister, Nova, Fire Blood and Ice Blood, plus a Nova wind up. On the third trial his health and damage go up 30% and the escorts go up 20%.
What the fourth class unlocks
- The Enhance Skill Tree, on the N key, with another 400 points and a different structure from the master tree: groups per skill, two prerequisites per node and 16 passives whose ceiling rises as you invest.
- Retroactive points: when you evolve, you receive at once the enhance points you would already have earned from your master level, capped at 400. Without that, anyone already at the master cap would never earn a single point.
- Gear that asks for a high total level: the mastery weapon and armor tiers above Holyangel.
- The fifth evolution, which only opens from here.
Fourth to fifth class
The last evolution is the simplest of all: the 5th Class Upgrade quest, with Eunice in Devias (193, 11). It asks for total level 1200, charges no zen and asks for no kills and no items. The reward is 200 stat points and the evolution.
Corrections to what people say
- The fourth class costs 20 million zen.
- The fourth class quest is number 7, and the fifth is 8.
- For the fourth class you just reach the total level and talk to the NPC.
- The fifth class opens the Season 20 ability tree.
- The last two evolutions are free. The original charges no zen and the server followed that.
- The fourth uses quests 7, 8 and 9 and the fifth uses 10, as in Season 20.
- There are three trials with mandatory combat against Cent, in an instanced arena.
- The one that opens the Enhance Skill Tree is the fourth class. The fifth opens nothing today.
