The Story of the Archangel and Blood Castle
Blood Castle |
The Archangel, one of the most powerful warriors on the continent of MU, has secretly protected these lands for centuries. However, the threat of Kundun now looms over the castle and its surroundings, and hordes of monsters are trying to invade the continent.
The Archangel, despite his strength, cannot fight alone. Wounded and on the brink of collapse, he calls upon the brave warriors of MU to come to his aid in his most critical hour. Without his divine weapon, the Archangel cannot defend the castle — and this is where your courage and skill come into play. Your mission is to infiltrate Blood Castle, now dominated by enemy forces, recover the Archangel’s weapon, and return it to him to restore his power. With the help of the Cloak of Invisibility, you can enter undetected and face the challenges that await. Do you have what it takes to overcome the dangers of the castle and complete your mission? |

Divine Sword of Archangel
Divine Crossbow of Archangel
Divine Staff of Archangel
Once you deliver the weapon, all remaining monsters will disappear, and you can choose whether to keep hunting for extra experience or finish the event.
Remember to coordinate with your party and use proper strategies to clear the harder levels, taking advantage of the Cloak of Invisibility to enter the castle undetected.
How to Enter Blood Castle
To enter Blood Castle, you need a Cloak of Invisibility, which is obtained by combining a Scroll of Archangel, a Blood Bone, and a Jewel of Chaos at the Chaos Goblin machine.
Only the first 10 players who show the Cloak of Invisibility to the NPC Spirit of Archangel can enter the castle.
Important Rules:
- Entry is available 6 times per day (may vary on different MU Online servers).
- PK status characters cannot enter.
- If you die inside, you will be automatically transported to Devias without losing experience or Zen.
- Trading and PvP are not allowed inside Blood Castle.
- Keep your party active during the event to coordinate entry and increase chances of success.

How to Create the Cloak of Invisibility
To enter Blood Castle, you need a Cloak of Invisibility. This is obtained by combining the following items at the Chaos Goblin machine:
Important: Only items of the same level can be combined. For example, a Scroll of Archangel +3 can only be combined with a Blood Bone +3 and a Jewel of Chaos to create a Cloak of Invisibility +3. If the combination fails, all items are destroyed.
Scroll of Archangel +N
Blood Bone +N
Jewel of Chaos
Cloak of Invisibility +N
Example of levels:
- Scroll of Archangel +3 + Blood Bone +3 + Jewel of Chaos = Cloak of Invisibility +3
- Scroll of Archangel +5 + Blood Bone +5 + Jewel of Chaos = Cloak of Invisibility +5
Remember: combining items of different levels will fail and destroy all items. Always use items of the same level to guarantee entry into Blood Castle.
