MU Online Castle Siege Guide - How to Join Fast

Castle Siege Requirements (Can I Join?)

Here is a simple checklist to see if your guild can join MU Online Castle Siege:

• Guild Required: You must be in a guild. Only guilds can own the castle; solo players cannot win it. Tip: you can create a guild at davias town (215, 45) in the center of the city where the NPC "Royal Guard Captain Lorence" is located.
• Minimum Members: Your guild must have at least 20 members to be a real siege guild.
• Guild Master Level: The Guild Master must be at least level 200 (any class).
• Sign of Lord / Mark of Lord: Your guild must submit enough Sign of Lord items during the registration period to be in the top 3 guilds. These items drop from monsters and can stack up to 255.
• Alliances Required: To use all castle features, your main siege guild should have at least one ally guild. You can have up to 2 allied guilds in total.
• Max Siege Guilds: Only 3 main guilds plus their allies can join each Castle Siege. Others can still enter as neutral but cannot win the castle.
• Defender Guild: The guild that already owns the castle is always the main defender. The other 2 siege guilds are usually attackers.
• Neutral Participants: Other guilds or players may enter as neutral to PvP, but they cannot become Castle Lord.
• Gear & Supplies: Bring repaired gear, wings, potions, scrolls, and buffs. Castle Siege is full PvP with many deaths.

Castle Siege Time & How to Enter the Map

• Event Map: Valley of Loren is the main Castle Siege map. It is a full PK and PvP-enabled area.
• How to Reach Loren: Go from Lorencia (239, 13) to Loren Canyon, then to Valley of Loren (32, 41).
• Castle Entry Points:
  • First gate of the castle: Valley of Loren (94, 112)
  • In front of the Throne Room (Dragon Tower): Valley of Loren (90, 240)
• Who Can Enter the Siege Area: Registered attackers, defenders, their allies, and neutral characters can enter Valley of Loren. Only registered siege guilds can win the castle.

How Castle Siege Works in MU Online

Castle Siege is a weekly event where guilds fight to control the only castle in the server cluster. The event has several phases with different goals:

• Guild Registration: Guild Masters talk to Guardsman and click “Announce” to show they want to join Castle Siege.
• Sign of Lord (Rank) Registration: Guild members turn in Sign of Lord / Mark of Lord to Guardsman. The game shows a ranking list of guilds by score.
• Selection: The top 3 guilds in this ranking, plus their allied guilds, are chosen as siege participants. One of them is the defending castle owner, the others are attackers.
• Preparation: The castle guild uses a special NPC (often called Senior NPC) in the castle to upgrade gates and guardian statues, set taxes, and place guards, archers, soldiers, and Life Stones.
• Castle Siege Battle: Attackers try to break through the gates, destroy guardian statues, move into the Dragon Tower, and register their guild seal on the throne. Defenders try to stop them and protect the castle.

Castle Siege Rules & Event Mechanics

• Attack & Defense Icons: During the siege, attackers have a sword icon above their heads, defenders have a shield icon, and Guild Masters have a crown (blue for defenders, red for attackers). Neutral players have no icon.
• PK Rules in Valley of Loren: Siege participants (attackers and defenders) can attack each other without pressing CTRL and there is no PK penalty and no item drop on death. Neutral players still use normal PK rules and must press CTRL to attack.
• Siege Weapons: Attackers can use Siege Golems and Catapults to destroy castle gates and barricades faster.
• Castle Gates: Gates have high HP and defense. They can be upgraded up to 3 levels. When you attack gates or guardian statues, your weapon durability loses faster, so use Potion of Bless/Soul to protect gear.
• Guardian Statues & Guard Towers: There are 4 guardian statues inside the castle. They heal nearby defenders and control a magic shield to the Dragon Tower. Guard towers protect these statues. Destroy all 4 statues to remove the shield and open the Dragon Tower entrance.
• Life Stones: Only the Guild Master or Assistant Guild Master of the invading team can place a Life Stone. It becomes a respawn point for that guild and also slowly restores HP/MP/AG to allies around it. Life Stones can be destroyed by both sides.
• Life Stone Recipe (Chaos Mix):
  1x Life Stone = 5x Jewel of Bless + 5x Jewel of Soul + 1x Jewel of Guardian + 1x Jewel of Chaos + 5,000,000 Zen.
• Movement & Warp: The guild that owns the castle (and its united guilds) can warp around Loren. During siege, the normal warp command is limited, but the defending team can still warp in front of the castle using Town Portal Scroll.
• Guild Lock: You cannot change guild, alliance, or cancel registration once Castle Siege starts.

How to Win Castle Siege

The guild (or alliance) that controls the Throne Room and has its official seal registered on the pedestal when the siege timer ends becomes the new Castle Lord.

• Dragon Tower & Pedestal: At the top of the castle is the Dragon Tower. Inside is the pedestal where the castle’s official seal is registered.
• Who Can Register the Seal: Only the Guild Master of a siege guild can stamp the official seal on the pedestal.
• Stamping the Seal: The Guild Master must stand on the pedestal and channel for about 30 seconds. Two allies must stand on the foot holders nearby. If any of them move or the Guild Master dies, the stamp fails.
• Changing Sides: If an attacker successfully registers the seal, they become the new defender, and the former defenders become attackers for the remaining time.
• Final Winner: When the siege time is over, the guild that has its seal on the pedestal at that moment is the winner and keeps the castle until the next siege.
• Play with Roles: Tanks guard gates and the Guild Master, damage dealers wipe enemies, supports keep buffs and heals up, and fast classes rush switches and Life Stones.
• Use Voice Chat: Short calls like “kill Life Stone”, “protect GM”, “push gate”, and “defend Throne” help a lot more than typing.

Castle Siege Rewards

• Zen & Jewels: Players can receive Zen and jewels such as Jewel of Bless and Jewel of Soul for joining and doing objectives.
• Castle Lord Privileges: The winning Guild Master becomes Castle Lord and can access special shops and systems inside the castle.
• Lord Mix: The castle guild can craft Lord Mix for powerful high-end gear and bonuses.
• Tax System: The Castle Lord can set tax rates for NPC shops and the Chaos Goblin. Tax is applied after clicking “Apply” and is stored at the Senior NPC as Zen. Only the Castle Lord can withdraw this Zen.
• Server Buffs: On many servers, if the castle is under good leadership, everyone may enjoy better drop rates or cheaper services.

Castle Siege Tips & Simple Strategies

• Prepare Before Siege: Repair all items, restock potions, and set your skill hotkeys. Make sure you have Town Portal Scrolls.
• Use Parties: Make full parties with clear roles (tank, damage, support). Parties are allowed in Valley of Loren.
• Focus Fire: Do not hit random players. Focus the Guild Master, supports, and high DPS enemies first.
• Watch the Timer: The last 5–10 minutes decide who keeps the seal. Plan your strongest attack or defense for this time.
• Control Life Stones: As defenders, always destroy enemy Life Stones. As attackers, protect your Life Stones and place them smartly near key areas.
• Learn Siege Skills: Some special Castle Siege-only skills exist, like Stun, Cancel Stun, Swell Mana, Invisibility, Cancel Invisibility, and Abolish Magic (for Battle Masters, Guild Masters, and Dark Lords). Use them for big team fights.
