Teleportation in Loren

The guild that owns the castle (including the merged guild) can teleport through Loren canyon to the castle.

*Teleportation cannot be used during a Siege, however the besieged team can teleport to the castle using the "Town portal scroll".

Main functions (components) of the lock

Castle Gate

  • Castle gates have a certain Defense, HP, and Durability, and can be attacked (but do not attack) during a siege. When attacking a gate, weapon durability rapidly decreases, so using a Potion of Bless is highly recommended.
  • The gates will not be restored until the siege is over.
  • Gates can be upgraded to a maximum of 3 levels of defense and durability. (Upgrading and restoring gates during battle is not possible.)
Castle GatesThe castle is divided into three parts (sections) by walls and gates. Each subsequent section can be reached by destroying only one gate.

Guardian Statues

  • Once all 4 statues in the castle are destroyed, the Dragon Tower shield will be removed.
  • Only players on the defending team can pass through the shield.
  • HP/MP/AG are restored near the statue. The restoration level can be raised to a maximum of 3.
  • Statues have a certain amount of defense, strength, and durability. They can be attacked (but do not attack) only during a siege. While attacking statues, weapon durability drops rapidly, so using a Potion of Bless is highly recommended.
  • Statues can be upgraded to a maximum of 3 levels of defense, strength, and durability (upgrading and restoring statues during battle is not possible).

[Destroy 4 Guardian Statues to enter the Dragon Tower.]

Towers (Cannon Towers)

Once the battle begins, the Statues will be protected by towers.

Towers attack players around them.

Towers can be attacked and destroyed in the same way as Statues or Castle Gates. However, this is not mandatory.

Dragon Tower

This enormous tower is located at the very end of the castle. It is divided into a walled entrance and an upper floor.

On the top floor of the tower there is a "room" for the owner of the castle and a pedestal with a seal.


The entrance to the tower is protected by a shield, which blocks entry for the attacking team.

To get there, you need to destroy 4 statues.


Setting up a seal

On the top floor of the tower there is a "room" for the owner of the castle and a pedestal with a seal.

Once the Guild Master of the attacking alliance sets their seal, the Sword Icon above their head will change to a Shield Icon, and they will have to defend their castle.

The guild whose seal is present at the end of the siege becomes the Owner of the castle.

Siege weapons

Siege weapons are placed in the appropriate locations for the attacking and besieged teams.

Click on a weapon to view the menu and select the area to attack.

Players can observe the attack of a siege weapon.

Only the Guild Master and Assistant GM can place soldiers.

A maximum of 100 soldiers can be deployed at any time after the siege begins. Soldiers will appear where you place them and will begin attacking the attackers immediately upon arrival.
