i was trying to make something for governors which is not so hard but what im uncapable of making is giving exp to them

the only reference is the adv guild but it uses something i cant use in a simple way

is there any unitstatbonus that i can apply to units instead of stationedunitstatbonus etc etc ?

adjustunitstat doesnt seem to work with experience

otherwise i was thinking something more complicated like giving a buff to the city similar to adv guild

then i give another buff to the champion "is governing"

then i make a calculation for the city buff that get the stat is governing so only the stationed champions with it gain the exp

the problem here would be another, how can i make the spell target the city? the spell its a self buff but i want 1 effect to target the tile or something

is there any modtype/attribute to target the tile the unit is in or its stationed city?
