The clan hall belongs to the category of elite clan residences: the clan leader can use a wyvern.
Siege registration
The clan hall siege takes place every two weeks on Thursday at 21.00.
A candidate clan for the residence must be at least level 4.
A registered candidate clan can have no more than 14 representatives, and each participant's level must be above 85.
Registration for the capture ends 2 hours before the siege starts.
The clan that owns the residence is registered for the siege automatically.
After registering, the player gets a skill to summon HeraldLoken, which sends clan hall capture parties into time zones.
NPC lets people in for 5 minutes after being summoned.
The clan hall capture procedure
The clan hall siege lasts an hour, from 21.00 to 22.00.
If the candidate clans don't finish within the time allotted for the capture, the residence stays with its current owner.
If the candidate clans finish within the allotted time, the clan that completed the time zone's tasks fastest becomes the clan hall's owner.
On the grounds of the Devastated Castle there are three bases, and next to them are three bosses - Mikhail, Dietrich and Gustav - who are invulnerable at first.
To remove the invulnerability, you need to capture the base next to the boss.
Monsters appear on the grounds of Devastated Castle; killing them can give special Scroll: Stronghold Siege. The scrolls come in 10-50 seconds; the number of seconds is the scroll's casting time.
After a scroll is used, the base of Mikhail starts moving; when it reaches the opposite side, the boss's invulnerability is restored and/or the boss is resurrected. To prevent this, players have to use sleep and immobilizing debuffs.
After a scroll is used, the base of Dietrich starts restoring its own HP; when it reaches the maximum, the boss's invulnerability is restored and/or the boss is resurrected. To prevent this, players have to keep attacking the base.
To remove the invulnerability from Gustav, Mikhail and Dietrich must be destroyed, and their bases must be in the captured state. After a scroll is used, you have 3 minutes to destroy Gustav. After 3 minutes the invulnerability is restored, and Gustav's health recovers to 100%. Until Gustav is killed, you mustn't let the first and second bases return to the uncaptured state, or the bosses will be resurrected and everything will have to start over.
After killing Gustav, the clan gets 100 clan reputation points and the players 1000 fame each.
If a clan holds on to the clan hall, it gets 500 clan reputation points.
