City Protection Tokens are used to give the player's city a full eight hours of protection from other player's Plundering attempts in the Wilds. While protected, your city will display a countdown timer informing other players how long the protection lasts. The tokens are stackable allowing you to leave for the weekend or on vacation with no fear of being attacked. The protection will be removed if the player attempts to plunder another player's city in that period. A popup will warn you of this before your attack may proceed.
City Protection Tokens can be bought in the Shop for 195 Balens. They may also be obtained from the Guild Altar or found in Mystery Boxes in Campaigns or Multiplayer Dungeons. Outside the shop, the tokens are very rare.
