Promotion

A promotion is a feature awarded to a unit, depending on its level of experience, that gives the unit a certain bonus (strength, defence, abilities...).

Certain promotions are usually available after a certain technology is discovered. Other are available only to certain categories of units, or could be triggered only by special units, such as Great generals.

All new promotions have an escalating cost, i.e. a higher level of experience will be required in order to receive a new promotion.

There are currently 557 promotions.
