There are four main resources in Art of War: Legions - gold, food, wood, and stone. These resources are used to train and upgrade your troops, as well as construct buildings and defences. Gold can be acquired by winning battles, questing, and looting enemy camps. Food is needed to sustain your troops, and can be acquired through farming or scavenging. Wood and stone are used for construction projects, and can be gathered from resource sites around the map.
