Craft bars

Spies with 60%, 5% and 100% craft.

Craft Craft is an expendable, renewable "resource" used by various units in the game, appearing as a small blue bar above a unit's hit points bar. Craft Craft is somewhat similar to the concept of mana, magic points (MP) or spell points (SP) employed by many fantasy-themed games.

Craft Craft regenerates automatically at a set rate, which can be increased by researching Strategy technologies at Forts.

Spies, Generals, Patriots, and all Scouts require Craft Craft to use their special abilities.

Craft Craft is also used to simulate fuel capacity of Fighters and Bombers, which in turn is used to limit the operation range of these units.
