Netmarble is set to host the first 'Clan War' for Vampir on the 27th and 28th.

The Clan War is structured as a three-tier affair: a preliminary round to crown the best clan within a server, a selection round matching servers against one another to determine finalists, and a grand finale where the top two clans battle for the ultimate title.

This inaugural event serves as a pre-season, with the top three clans from each server—ranked by combat power as of midnight on the 27th—taking part. The preliminary round takes place on the 27th, followed by the selection and final rounds on the 28th.

In the preliminaries and selection rounds, points are earned by landing the final blow on named monsters or taking down rival players. The finals shift the focus, requiring clans to seize the Altar of Blood and the Great Altar of Blood for periodic scoring, while also hunting down the Forgotten Monarch and various abominations to pad their totals.

The clan that tops the preliminary round walks away with 500,000 Diamonds and the right to dictate world boss spawn times. As for the grand finale, the champions claim 60% of the 5,000,000 Diamond prize pool. They also earn exclusive perks, including the ability to issue chat bans, set Gehenna boss spawn times, and dictate entry points for Gehenna Zone 2. The runners-up also receive a share of the total prize based on their contribution.
