Energy icon.
Energy is a static resource in the MegaPack techtree, used solely by the Magic faction. It is required for producing units, and is not harvested from any tileset object, as many resources are.
Obtaining[]
Energy is only obtained from one source: the Energy Source building, which produces 14 energy when built.
Usage[]
In Magic, energy is only used to produce units, requiring either 1 or 2 energy, depending on the strength of the unit.
