Weekly Top Donor Rewards

Every Monday at reset, the top 10 active donors in each alliance receive bonus Alliance Credits. The weekly donation leaderboard shows the current reward tiers.

Alliance Territory

Alliance Leadership can project a territory on the Galaxy Map by deploying an Ephoran Vault. The radius of this territory can be expanded via Alliance Research.

Claimed territory borders, owning alliance, and alliance color are visible to every player in the relevant Galaxy Map area. The strategic view keeps its existing visibility rules.

  • Vault Placement: An Ephoran Vault requires maximum Territory Size clearance from Trading Stations and other Ephoran Vaults, preventing future territory expansion conflicts.
  • Home Advantage: Fighting within your Alliance Territory grants a +10% bonus to Unit Attack and +10% bonus to Unit Defense.
  • Territory Control: Prevents enemies from teleporting their bases or deploying vaults inside your territory.
