How do you determine the upkeep cost of a unit?

[Endoperez]

The transformed units use the upkeep value of the new creature. I think it's 0 for all or almost all of them.


Prophets' upkeep is either halved or negated. This can be useful for nations with very expensive commanders in early game, especially for something like Luck-scale Pangaea which might not have that much money readily available.
