Strategic Resources

Strategic Resources are used to create weapons, armor and accessories that increase the effectiveness of heroes and units, and are also required to create some of the more advanced City Improvements and Expansions. The Vaulters can use Strategic Resources as a special booster, similar to Luxury Resources, making the selected strategic resource the Holy Resource for the duration. Strategic Resources current totals are recorded in the Empire interface.

Strategic Resources are obtained either by constructing Extractors on resource deposits found on the map, or by direct purchase from the Marketplace. Extractor construction is unlocked in specific Eras by technological research, whereas the ability to purchase resources from the Market is unlocked by the Era II technology Imperial Coinage.

Having a Strategic Resource on a terrain tile adds an additional +1 Science to the terrain tile.
