  • Control of a structure (castle/territory);
  • Exclusive benefits (taxes, access, NPCs);
  • Maximum prestige on the server;
  • Rewards for members.
Nota: The Arca War and territory events only exist in modern seasons. The Castle Siege has been present since the classic versions.

How to prepare

  • Build an organized guild (and alliances);
  • Coordinate attack/defense strategy;
  • Have well-equipped members;
