Blood Castle

Blood Castle event occurs every other hour on the :30.
To begin the event, purchase a Cloak of Invisibility from Lumen the barmaid. For the cloak level you need, see the first picture.
Once you have the cloak, speak to the archangel.

The "Jewel Stacking" level is the Master Level, that requires a cloak+8.
Once inside the castle, you must wait for the event to begin.
Once it begins, you must kill a set number of monsters.

The number of monster kills needed will increase with the number of players in your castle level.
After the monsters are killed, you must destroy the gates.

Once inside the gates, you must kill a set number of "magic skulls".

Again, the number needed increases with the number of players in your castle.
After the skulls are killed, you must destroy the statue, and retrieve the weapon.


The weapon may be a sword, staff, or crossbow.
Once you have the weapon, you must return it to the archangel.
Here is where it gets tricky.
If you try to return it immediately, you will receive this message:

What you need to do, is wait for the timer to say under 5 seconds remain, like this:

Then talk to the archangel to receive your prize; one jewel of soul.

I hope this guide has been helpful for both new players who don't know how Blood Castle works and veterans who are confused about why they cannot return the weapon right off.
