Blood Castle in MU Online: complete guide

Blood Castle is MU's party event: up to 10 players per castle cross the bridge, break the gate, smash the statue and bring the weapon back to the Archangel. A match lasts 20 minutes and opens every 3 hours, on the hour. The exact time in your time zone is on the events page.

Which castle is yours

The castle depends on your character's level. Magic Gladiator and Dark Lord have their own range.

castle	Dark Knight, Dark Wizard, Fairy Elf	Magic Gladiator, Dark Lord
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, third class only	any level, third class only

Blood Castle 8 requires the third class: Blade Master, Grand Master, High Elf, Duel Master or Lord Emperor.

The ticket: Cloak of Invisibility

Hunt a Scroll of Archangel and a Blood Bone of the same level as the castle. Both pieces drop from monsters, at 1% each, and no NPC sells them.
Take both pieces and one Jewel of Chaos to the Chaos Goblin, in Noria 180,103.
The combination succeeds 80% of the time and gives you the Cloak of Invisibility of that level.

The piece's level follows the level of the monster that dropped it:

piece	monster level
+1	2 to 31
+2	32 to 44
+3	45 to 56
+4	57 to 67
+5	68 to 75
+6	76 to 83
+7	84 to 94
+8	95 and up

The Cloak's level must match the castle for your range: a +3 Cloak only opens Blood Castle 3. The ticket is used up when you enter.

How to enter

Talk to the Archangel Messenger, in Devias 217,29, with the Cloak in your inventory. Get there before the hour: the entrance stays open for only 1 minute after the event opens.

Your active buffs are removed when you enter. Buff again inside.

How the match works

The bridge. Kill the monsters in the first area until the bridge to the castle opens.
The gate. Break the Castle Gate. Whoever breaks it gets bonus experience; party members who already died get half of it.
The statue. Stronger monsters wait behind the gate. After them, the Statue of Saint appears. Breaking it announces the name of whoever broke it to the whole map and drops the Archangel's weapon.
The delivery. Whoever picks up the weapon has to carry it to the Archangel, at the castle altar. Delivering it ends the event and decides the winner.

Whoever dies carrying the weapon drops it on the ground, and the race starts over. If nobody delivers it before the 20 minutes run out, nobody wins.

What you get

Experience for every second left: the sooner the weapon reaches the altar, the more EXP for everyone.
Zen: the winning party gets double.
Jewels:

castle	jewel	who gets it
Blood Castle 1 to 6	1 guaranteed Jewel of Bless or Jewel of Chaos	whoever delivers to the Archangel, and their party
Blood Castle 7 and 8	1 guaranteed Jewel of Soul or Jewel of Bless, plus a 60% chance of Chaos, Creation or Life	the guaranteed one goes to the whole party; the 60% one only to whoever delivered

Finishing Blood Castle is one of the few sources of Jewel of Creation. See them all in jewels and economy.

Tips

Go in as a party. The reward goes to the deliverer's party, and the winning party gets double zen.
Agree on who carries the weapon. The toughest character takes the weapon; the rest clear the way to the altar.
Leave inventory space. The reward goes to your inventory; if it's full, it drops on the ground. After the end you have only 1 minute before you're taken out.
Keep the pieces that drop. With a pair ready and a Jewel of Chaos saved, you won't miss the next run.
Between events, play with Idle. The ticket pieces drop from monsters, and Idle hunts on its own while you wait for the next opening.
