Sieges are the most ambitious aspects of Lineage II, so their scale and systems are exciting factors in the game. Clans that have reached level 4 can occupy a castle and enjoy the fame and riches therein. Once they own a castle, clans can exercise tremendous influence in terms of tax rate adjustments and political activities..
Sieges take place at the castles of Gludio Castle, Dion Castle, Giran Castle, Oren Castle, Innadril Castle, Goddard Castle, Schuttgart Castle, Rune Castle, and Aden Castle. There are also unique clan halls where ownership is acquired by battle with NPCs.
Only clans of level 4 and above can officially participate in a siege. Clans that are less than level 4 or players not belonging to a clan may still participate as non-related parties, but they do not have the right to own a castle.
Unless the castle is captured by a clan, it remains in NPC control.
If there is a PC clan that defeats the NPC clan and occupies the castle according to the rules of the siege, the castle becomes the property of that PC clan.
The very first castle lord must, within 24 hours of becoming castle lord, designate the time for the next siege. If this is not done, the default siege time will be applied automatically.
The Grand Olympiad is a one-on-one PvP competition held to determine the Hero. It is held in one month period, and at the end of each period, the Noblesse with the most Olympiad points in each class is appointed Hero. Only Noblesse who have completed the third class transfer can participate in the Olympiad competition.
The Grand Olympiad is classified into two competitions: the class competition and the non-class competition. Only members of a certain class can partake in class competitions. There are no class restrictions for participating in non-class competitions.
Seven Signs as the Seven Seals that bind the power of Shilen, the goddess of death, are opened one by one, the world moves closer to the brink of chaos. Each Seal contains a great power that could cause the world to tremble. The one who opens the Seals can control the power contained within them. The Revolutionary Army of Dusk and the Lords of Dawn compete against each other toward this end. Players join one of these two cabals who vie for control over the power of the Seals
An unlimited number of players can join the Seven Signs quest, which repeats in two-week intervals. Based on the results of the Seven Signs, players can change the status of their server.
Players participating in the Seven Signs gather their forces. The fight between the Cabals reflects the nature of the confrontation between those who hold a castle and those who do not. However, players who fail to make a second change of occupation fall into a "neutral group" and may participate in either the Dusk or Dawn side .
