Building Types & Decay Rates

  • Wood: 8 hours to start decay, 24 hours total
  • Stone: 24 hours to start decay, 48 hours total
  • Metal: 48 hours to start decay, 96 hours total
  • Armored: 72 hours to start decay, 144 hours total
  • HQM: 96 hours to start decay, 192 hours total

Tool Cupboard Mechanics

  • TC provides 24 hours of protection
  • Requires building materials for upkeep
  • Different materials have different upkeep costs
  • Upkeep costs increase with base size
  • Empty TC decays in 24 hours

Raiding Strategy

  • Decay weakens walls, making them easier to raid
  • Check for decay before planning raids
  • Decayed bases require fewer explosives
  • Timing raids around decay can save resources
  • Monitor enemy base decay times
