Changes

Key:  Additions   Deletions
The following information was taken from here. I have slightly edited some of the wording as well as added in pictures to make it easier to understand, but overall it's basically the same.

If you want to see some Castle Siege screenshots, check the Merac Castle Siege screenshots page.

------------------------------

Castle Siege is a contest to decide the owner of Kandant Castle, located in southeastern Merac. The first time Kandant Castle was up for grabs, there were only attackers. At this point in time, however, the Castles on all servers are owned, so for each Siege there are both attackers and defenders. Read on to find out more about these roles and how the Siege actually happens. Kandant Castle

Siege participation and application

You can apply to participate in a Castle Siege through the Chamberlain NPC located in the southwest corner of Kandant Castle. You may participate in a Siege as an Attacker in a guild, a Mercenary Attacker, a Defender of the Castle guild, or a Mercenary Defender.

Guild Application -
Medal of HonorOnly the Guild Master may apply for their guild. The guild needs to be level 5 and have twenty or more members. The Guild Master must also be in possession of a Medal of Honor, which can be acquired from drops off of Boss Monsters.

Mercenary Application -
Mercenaries are individuals who wish to help with the Castle Siege as an attacker or defender. To participate as a Mercenary Attacker/Defender you must be level 15 or higher, and to participate as a Mercenary Attacker/Defender Guild your guild must be at least level 4.

Preparing for the Siege

Ten minutes before a Castle Siege starts all participants move to the Siege areas for the attackers or for the defenders (where you move depends on what you've signed up to be). On the field of battle outside the Castle there will be an NPC named Vagabond Merchant Bella selling various offensive items to help the attackers. Inside the Castle there will be an NPC named Vagabond Armor Seller Neime selling various defensive items to help the defenders.

Castle Siege-specific items

Castle Siege-specific items are only available during a Castle Siege and only available from the Castle Siege vagabond merchant NPCs. By purchasing materials from a vagabond merchant and combining them, you can create new and unique Castle Siege accessories to aid you in combat. There are three types of materials you available for purchase from a Siege vagabond merchant: Concentration Gems, Dusts, and Stones. By combining these three materials in different ways you can get up to 80 different possible results.

(Thanks go to Gospodja for helping me get the missing CS item pictures!)

Castle Siege accessories will lose their power if the Castle Siege ends or if a character moves outside of the Siege area. The Siege Merchants will also disappear after a Castle Siege ends.

Unfortunately, the materials for making these Castle accessories will not disappear. Some people try to sell them on the general market as being "rare accessories." The materials are useless, however, in normal gameplay. Do not fall for this scam.

Map and radar

All participants in the Castle Siege can use the map and radar features after a Castle Siege starts.


Signal button
During the Siege a Guild Master or Guild Advisor can click the Signal Check Icon in the top right-hand corner of the screen above the radar. This will change the mouse cursor into a Signal Mark Icon. They can then click within the radar or on the mini-map to set a beacon for all other guild members to see. The mini-map will alsodisplayalso display the guild's Starting Point, the location of the Throne of Power, the Gate, and the Guard Towers / Giant Statues.

Siege procedure

Basic rules of the Siege -
  1. Castle Siege is limited to 15 minutes for the Field Battle and a maximum of 45 minutes for the Inner Castle Siege. If a Guild Master destroys the Throne of Power and claims the Feudal Lord's Weapon for their own before the time is up, then the Castle Siege ends.
  2. During the Castle Siege all PvP penalties and death penalties are disabled.
  3. During the Castle Siege, Attacking/Defending Guilds and the Mercenary Guilds cannot drop, join, or reassign members to their guild. Also during this time Guild Wars do not apply in the Merac region.
  4. During the Castle Siege, participants within regeneration areas gain an improved recovery rate, offensive power, and defensive power.
  5. During the Castle Siege all participants are distinguished as shown below.

Field Battle -
The Field Battle decides the three guilds who will have the right to challenge the Castle Owner guild. The three top guilds who obtain the most points within the 15 minute limit will have the right to challenge the Castle Owner.
  1. The Castle defenders may participate in the Field Battle by using Warpgates found in the Castle. By challenging and defeating members of enemy guilds, the defenders add to the Giant Statues' and Guard Towers' defense points.
  2. The attacking guilds must fight with all characters on the field of battle excluding their own guildmates. Guilds gain points by defeating enemy characters during the Field Battle.
  3. The three guilds with the Highest Points at the end of the 15 minute limit, will then be eligible to challenge the Castle Owner and begin the Inner Castle Siege.

Inner Castle Siege -
After the Field Battle, the top three "chosen" guilds will begin the true Castle Siege!
  1. When the Castle Siege begins the Defenders move to the inside of the Castle, and the two Outer Gates and one Inner Gate are closed. The Guard Towers and Giant Statues are then raised on either side of the Gates. Attackers must destroy the Guard Towers and Giant Statues before the Gates will open.
  2. Defenders can move to the outside of the Castle to assault the attackers by using Warpgates found within the Castle Walls. There are four different Warpgates (A, B, C, and D) connecting the inside and outside of the Castle. Paths for the Warpgates are explained below.

Castle ownership -
After the Gates have been opened, the Throne of Power can be challenged. Only the Guild Masters of the top three guilds have the right to become Castle Owner, and they are the only ones who can attempt to destroy the Throne of Power, remove the Feudal Lord's Weapon, and claim rightful ownership to Kandant Castle.
If no Guild Master is able to destroy the Throne of Power and remove the weapon within the 45-minute time period, then the Castle Defenders are successful and retain ownership of Kandant Castle.
  1. Points increase as a Guild Master attacks the Throne of Power and decreases when the Guild Master is killed.
  2. The Throne of Power can only be destroyed by using close range default attacks. Ranged attacks do not count and the Throne's HP decreases by 1 regardless of the attack's power.
  3. Guild Masters are identified by a glowing shield over their head, making them a very visible target.

Rights of the Castle Owner

Reigning a region -
Castle Notice button Once a player becomes the Owner of Kandant Castle, they can make server notices announcing their ownership and reign over Kandant Castle. This is done by clicking the Castle Owner Notice button in the Guild Action window

Feudal Lord's Weapon -
When a guild becomes owner of Kandant Castle, they do so by having their Guild Master pull the Feudal Lord's Weapon from the Throne of Power. It is then placed in the Guild Master's inventory and may be equipped at any time. Its abilities are based upon the owner's level. This is quite possibly the most powerful weapon in all of Iris.
  1. The Feudal Lord's Weapon cannot be purchased, exchanged, dropped, or upgraded, and can only be used by the owner of Kandant Castle.
  2. If the Castle Owners fail to defend the castle, the Feudal Lord's weapon will be removed from their Guild Master's inventory. Therefore, they must be successful in defending the castle if they wish to retain it.

Tax collection -
Taxes are 2%. All sales and purchases made from the Castle Siege NPCs shall be taxed. All sales made while a character is in package mode shall be taxed. All collected taxes will be found in the guild's safe located in the Guild Hall.

Castle Sieges happen on Katar-1, Cariae-1, Sarrisa-1, Hatzering-1 and Azura-1.Azura-1, and Tairen-1.
Castle Siege times are all EDT.


Upon winning castle siege -

After winning the castle siege, each member of the winning guild receives a full set of Castle Siege c2 covers, which can be seen and explained on the Castle Siege Covers guide.
