Unit upkeep

The upkeep of a unit represents how much it costs in gold per day to keep that unit fed and supplied. Units with a higher unit level and heroes with a higher experience level cost more to upkeep. If a leader is not able to supply a unit with sufficient funds, the unit's morale decreases. Low morale units may defect.

Upkeep costs by unit:

• Leaders cost no upkeep
• Heroes cost 5 plus 2 per experience level
• Other units cost  2 plus 2 per unit level
