Blood Castle
Twenty minutes to break the gate, bring down the statue and hand the weapon to the Archangel. Eight levels, one for each level range.
Updated on August 10, 2026Blood Castle is the most repeated event in Mu Online and it is still the most efficient way to turn time into experience between level 15 and 400. It is 20 minutes inside a closed corridor, with up to 10 players, and the faster the group finishes, the more experience is left to split.
- 8levels
- 20 minmatch length
- 10players per room
- 2 hbetween openings
It opens every two hours, always on the hour by the UTC clock: 00:00, 02:00, 04:00 and so on. In Brasilia time that lands on 21:00, 23:00, 01:00 and the rest of the ladder. The door stays open for 1 minute, so be at the NPC before the time, not after.
Which level you can enter
Each level has a closed level range, and Magic Gladiator, Dark Lord and Rage Fighter get in 20 levels earlier than the other classes. That column exists because those three classes climb more slowly at the start.
| Level | Level for normal classes | Level for MG, DL and RF | Note |
|---|---|---|---|
| Blood Castle 1 | 15 to 80 | 10 to 60 | |
| Blood Castle 2 | 81 to 130 | 61 to 110 | |
| Blood Castle 3 | 131 to 180 | 111 to 160 | |
| Blood Castle 4 | 181 to 230 | 161 to 210 | |
| Blood Castle 5 | 231 to 280 | 211 to 260 | |
| Blood Castle 6 | 281 to 330 | 261 to 310 | |
| Blood Castle 7 | 331 to 400 | 311 to 400 | |
| Blood Castle 8 | 331 to 400 | any level | master class only |
The ticket
The ticket is the Invisibility Cloak, and its `+N` has to match the Blood Castle level you want. A +3 cloak gets into Blood Castle 3 and nowhere else. There is no zen fee.
- 1Get the two pieces
Scroll of Archangel +N and Blood Bone +N, both at the same level. The Scroll is sold from +1 to +8 by Lumen the Barmaid, and from +1 to +2 by Caren.
- 2Go to the Chaos Goblin
He is in Noria, at 180,103. Put the two pieces in the machine.
- 3Combine
Out comes the Invisibility Cloak +N, at the same level as the pieces that went in.
- 4Talk to the Messenger of Archangel
He stands in Devias, at 217.29 and 217.20. He is the way in, and the whole party can go in together.
What to do inside
The sequence is always the same and each step only unlocks the next. Losing time on one of them is losing experience at the end, because the payout per remaining second is most of the total.
- 1Kill 40 monsters per player
The count is multiplied by the size of the group. When it closes, the bridge appears.
- 2Destroy the Castle Gate
The gate has 150 thousand to 650 thousand health, depending on the level. Once it falls, the passage opens.
- 3Kill 2 Spirit Sorcerer per player
Also multiplied by the group. When it closes, the Statue of Saint spawns at 14.95.
- 4Bring down the Statue of Saint
From 65 thousand to 345 thousand health, depending on the level. It always drops the Weapon of Archangel.
- 5Hand the weapon to the Archangel
The NPC stands at 10.9. Handing the weapon in ends the match with a win for everyone inside.
| Level | Gate health | Statue health |
|---|---|---|
| 1 | 150,000 | 65,000 |
| 2 | 205,000 | 105,000 |
| 3 | 260,000 | 145,000 |
| 4 | 325,000 | 185,000 |
| 5 | 400,000 | 225,000 |
| 6 | 480,000 | 265,000 |
| 7 | 565,000 | 305,000 |
| 8 | 650,000 | 345,000 |
What you get
The payout has four parts: experience for bringing down the gate, experience for bringing down the statue, experience for handing in the weapon and, the biggest one, experience for every second left on the clock. Finishing in 8 minutes instead of 15 is worth more than all the fixed bonuses put together.
| Level | Gate | Statue | Delivery | Per remaining second | Zen on a win | Zen on a loss |
|---|---|---|---|---|---|---|
| 1 | 20,000 | 20,000 | 5,000 | 160 | 20,000 | 10,000 |
| 2 | 50,000 | 50,000 | 10,000 | 180 | 50,000 | 25,000 |
| 3 | 80,000 | 80,000 | 15,000 | 200 | 100,000 | 50,000 |
| 4 | 90,000 | 90,000 | 20,000 | 220 | 150,000 | 80,000 |
| 5 | 100,000 | 100,000 | 25,000 | 240 | 200,000 | 100,000 |
| 6 | 110,000 | 110,000 | 30,000 | 260 | 250,000 | 120,000 |
| 7 | 120,000 | 120,000 | 35,000 | 280 | 250,000 | 120,000 |
| 8 | 130,000 | 130,000 | 40,000 | 300 | 250,000 | 120,000 |
Whoever wins and is alive at the end also takes a Jewel of Chaos. Dying does not throw you out of the match, but it does cost you the jewel.
