Castle Siege is the heart of guild PvP in MU Online. Configuring it well keeps guilds engaged and gives life to the server. Here are the key points.

The Castle Siege cycle

The event has phases through the week:

  1. Registration: guilds sign up by paying a fee;
  2. Marking: defining who attacks;
  3. Siege (battle): the war for the castle;
  4. Possession: the winning guild runs the castle until the next cycle.
Nota: The phase names and durations vary by season, but the register → battle → possess logic is always the same.

Atenção: Announce the Castle Siege time in advance (on the site and in game). Guilds need to organize — a siege without notice becomes an empty one.

Benefits for the owning guild

The winning guild usually gains: control of the castle and its associated Crywolf (in some seasons); tax collection at NPCs; access to exclusive areas/commands; and top prestige on the server.

Dica: Attractive (but not broken) rewards make guilds truly fight for the castle. That's what keeps the server's end game alive.

Perguntas frequentes

Where do I configure Castle Siege?

In the MuServer event files (often in an events folder or the database), where you set days, times, registration fee and phase durations.

How often should I run Castle Siege?

The classic default is weekly. Too often tires the guilds; too rarely cools interest. Weekly is usually the ideal balance.
