Resource buildings exist in every castle at a set number that cannot be changed. New players begin with 6 farms and 4 of each other resource in their first city. Empty city spots may have a different distribution of resource fields.
Players can increase production by upgrading resource buildings, by appointing a hero to the garrison, or by using game items to boost production. Four types of research affect resource production: Quarry, Smelt, Harvest, and Lumber.
It is also possible to get additional resources by levying a castle's population, but that produces resentment that can cause other problems. The Fortune Wheel sometimes gives away 40,000 of a resource. Players can buy and sell resources from other players through the Market, and can purchase resources instantly with game coins.
