Effect & research conditions
Research costs 1,500 Food and 2,000 Coin and takes 60 seconds. The age transition and Guard Cossacks access are granted when the research completes; the technology does not itself train Cossacks or pay for their later upgrade. Keep the Lavra Monastery active and protected throughout the full research window.
Research condition
Cossack Hetmanate Revolution; Lavra Monastery; 1,500 Food · 2,000 Coin; 60 seconds.
When to research
Begin the transition when the economy can spare both the resources and a minute of research time without losing the position. Decide in advance which Industrial Age units or upgrades will use it, then prepare Barracks or Stable production for the newly enabled Guard Cossacks improvement. If the army needs immediate reinforcements or the Lavra is under threat, delay the research until the base can support it.
Advance the Cossack Hetmanate
Grand Duchy of Ruthenia is a Cossack Hetmanate Revolution technology at the Lavra Monastery. It costs 1,500 Food and 2,000 Coin, takes 60 seconds and advances the player to the Industrial Age. It also enables the Guard Cossacks upgrade at the Barracks and Stable.
Prepare the Industrial transition
The long research time and high cost require a protected economy. Plan which Industrial Age units or upgrades will use the transition, then maintain the Lavra Monastery until completion. The Guard Cossacks unlock matters only if the army can produce the unit and afford the follow-up upgrade.
