Key Artifacts

Keys can be found as rewards for raids, obtained from the Fortune Teller as a daily prize, or purchased in the Shop. Using a key immediately increases the Town Hall to a perdetermined level, adds a quantity of Stone and Wood resources to the player's total, and increases construction speed for all buildings in a city for a specified amount of time.
