• On normal worlds, 2,500 units on each the attacker's and the defender's side are required
  • On Battle Worlds, there are 5,000 (Battleworld 1-5) / 10,000 (Battle AS, EU, US) units required on each side
  • Conquering a city costs 5 times the amount of silver that a regular fortress would cost.
  • When calculating the amount of silver a player needs to conquer another castle/fortress/city, any city that player owns is counted as 25 individual castles.
