Gold is the dominant resource in Magitech, having the most use and being used by all Magitech factions. Nearly every unit, building, and upgrade requires at least a little bit of gold. In short, gold is the currency-style resource.
Gold in Magitech must be harvested, namely from gold ore deposits on the map (shown to the right). How exactly this is harvested varies with the faction. In Magic, initiates can extract the gold from the gold ore in bunches of 20. In Tech, the worker can mine the gold ore in bunches of 25. Gold is also given back as a discount on morphing units sometimes, and from canceling the production of a unit that required gold.
Nearly every unit, building, and upgrade requires gold. For example, the Archmage requires 150 gold to morph from a Battlemage (however, since the Battlemage needs 75, as does the initiate, the total cost of the Archmage becomes 300 gold). Gold that is expended cannot be recovered unless the unit or upgrade is canceled before it is complete. It is not recovered if the producing or morphing unit/building is destroyed, as is standard with all resources.
