Resource
Resource is a common name for all basic and magical resources rescoureses. Basic resources include wood, ore and gold, while magic resources include mercury, sulfur, crystal and gem. Wood and ore are required to build town structures along with gold. Wood is also needed to build boats. Magical resources may also be required for buildings, but it is also needed to hire some of the 7th level creatures. Gold is basically needed for everthing from hiring heros and troops to constructing buildings and ships. Additionally, some Adventure Map locations (e.g. School of War) require Gold in exchance for their services.
Resources are typically received from mines, gathering loose resourced on Adventure map or visiting certain locations like windmill. A Freelancer's Guild allows hero to trade creatures for resources and Artifact Merchants allow heroes to exchange artifacts for gold. Additionally, resources can be given/received from other players through Marketplace.
