The Spies/Treason upgrade is a utility technology researched at the Castle. Spies (Random Map games) reveals all enemy units and buildings by showing you their line of sight. The total cost is 200 gold per each Villager from other players; allied Villagers are excluded when teams are locked. Treason (Regicide games) reveals the position of all enemy Kings to your team for a few seconds. The Kings appear on the mini-map as a flashing X. Each time you choose Treason, 400 gold is immediately deducted from your stockpile.
