Chaos Castle in MU Online: complete guide
Chaos Castle in MU Online: level range and entry fee of each castle, how to enter with the Armor of Guardsman, how to win solo and how many jewels it pays.
Chaos Castle is MU's survival event: everyone against everyone, and the floor vanishes under whoever is left. A match lasts 10 minutes and opens every 2 hours, on the hour. The exact time in your time zone is on the events page.
It is also the best source of Jewel of Bless and Jewel of Soul on the server, and you can win it solo.
Which castle is yours
The castle depends on your character's level. Magic Gladiator and Dark Lord have their own range. The entry fee is paid in zen.
| castle | Dark Knight, Dark Wizard, Fairy Elf | Magic Gladiator, Dark Lord | fee |
|---|---|---|---|
| Chaos Castle 1 | 15 to 49 | 15 to 29 | 25,000 |
| Chaos Castle 2 | 50 to 119 | 30 to 99 | 80,000 |
| Chaos Castle 3 | 120 to 179 | 100 to 159 | 150,000 |
| Chaos Castle 4 | 180 to 239 | 160 to 219 | 250,000 |
| Chaos Castle 5 | 240 to 299 | 220 to 279 | 400,000 |
| Chaos Castle 6 | 300 to 400 | 280 to 400 | 650,000 |
| Chaos Castle 7 | 400, third class only | 400, third class only | 1,000,000 |
Chaos Castle 7 requires level 400 and the third class: Blade Master, Grand Master, High Elf, Duel Master or Lord Emperor.
The ticket: Armor of Guardsman
The Armor of Guardsman drops from monsters: 1% chance from monsters level 2 and up, on the hunting maps. No NPC sells it, it can't be crafted and it needs no jewel.
How to enter
- Stand in a safe zone, such as a town.
- Right-click the Armor of Guardsman in your inventory.
- Have the zen for the fee. The game takes you to the castle for your range.
The entrance stays open for 5 minutes after the event opens. Chaos Castle doesn't allow parties: entering removes you from your party. Your active buffs are removed when you enter.
How the match works
- Up to 70 players enter. The map starts as a safe zone; when the event begins, it no longer is.
- Monsters fill the map up to 100 fighters, and they also fight each other.
- Die and you're out. A monster that dies doesn't respawn and may explode, pushing anyone nearby.
- The map shrinks three times: when fewer than 40, 30 and 20 fighters are left. Whoever is standing on the floor that vanished falls, and falling is dying.
- The winner is the last one standing, or whoever has the most kills when time runs out.
Each monster killed is worth 2 points and each player 1. The score goes to the event ranking.
Solo works too
Chaos Castle starts with a single player. Alone, you face 99 monsters and win when you kill them all. It is the surest way to collect jewels on the server: the whole quota is yours.
What you get
During the match, monsters drop a fixed quota of Jewel of Bless and Jewel of Soul, assigned at random among the kills. The higher the castle, the bigger the quota.
The winner, if alive, also gets a 90% chance of a random jewel among Bless, Soul, Chaos, Life and Creation. It is one of the few sources of Jewel of Creation. See them all in jewels and economy.
Tips
- Stay away from the edge. Exploding monsters push you, and the map shrinks from the edges. Fight in the middle.
- Pick up the jewels right away. They drop on the ground where the monster died. After the end you have only 1 minute before you're taken out.
- Leave inventory space. The winner's reward goes to your inventory; if it's full, it drops on the ground.
- Bring plenty of potions. There is no second chance inside the castle.
- Keep every Armor that drops. Each entry uses one, and Chaos Castle opens every two hours.
- Between events, play with Idle. Idle gathers the zen for the fee and hunts the next Armor while you wait for the next opening.
