Economic buildings are those centered around resource generation and storage. They include the storage and harvesting facilities for all of the game's key resources: Gold, Wood, Stone and Iron, as well as the Vault, which protects a portion of your resources even if your base is defeated by enemy attack. Below, you will find a close look at each of these buildings, the benefits of upgrading them, and any tactics associated with their construction and placement.
Function: This Building provides you with Gold every hour (or sooner if you tap on it in the meantime)
