Cost (Attribute)

Cost is an attribute of some units that is presented on faction sheets and unit upgrade technology cards. A unit’s cost determines the number of resources a player must spend to produce that unit.

To produce a unit, a player must spend a number of resources equal to or greater than the cost of the unit they are producing.
If the cost is accompanied by two icons—typically for fighters and ground forces—a player produces two of that unit for that cost.
If a unit does not have a cost, it cannot be produced.
  1. Structures do not have costs and are usually placed by resolving the “Construction” strategy card.
