The Enemy upgrades its entire Capital City by advancing an Action Token on a 6-space track, which marks its Capital City Level.
The Enemy MUST pay the Ore amount listed on the next open space. If it reaches the end of the track, it triggers the end of the game.
Increasing the Capital City Level grants more strength, VP, Constructs, and special abilities.
This action will fail if the Enemy does not have the required Resources available.
