Research condition
Available to Cossack Hetmanate from the Fortress Age. Research it at Rada. It requires Koniecpolski Estates.
When to research
The technology combines a 25% Villager bonus at Mines and Mountain Monasteries with a 50% Sejm automatic Coin bonus. It costs 1,200 Food and takes 40 seconds, and requires Koniecpolski Estates. Research it when the Cossack Hetmanate can use both mine income and the passive Sejm stream; a workforce focused elsewhere receives no value from the mine portion.
Mining and automatic Coin income
Vyshnevetsky Architecture raises Villager gathering from Mines and Mountain Monasteries by 25%, while increasing the Sejm’s automatic Coin gathering by 50%. The worker and building effects apply to different sources and should be assessed independently.
Cossack Hetmanate prerequisite
Available in the Fortress Age at the Rada after Koniecpolski Estates, the research costs 1,200 Food and takes 40 seconds. It is a focused economy investment whose return depends on continued mining and Sejm income.
