When to research

Research early enough to receive more intervals, reserve population, and keep a safe rally point so the arrivals can join the army.

Defensive package
The 60-second research costs 600 Wood and 600 Coin at a Trading Post or Tambo on a House of Wettin palace. It sends a Fort Wagon, increases the Fort build limit by one, and allows Forts to be constructed in the Commerce Age. It also unlocks Revetment and Star Fort. The effect combines an immediate mobile construction option with access to a longer defensive technology line.
Battery Tower Wagon deliveries
Königstein also provides one Battery Tower Wagon for every 10 minutes of game time, up to the 30-minute mark, for a maximum of three. These timed rewards make game time relevant when deciding whether to research it and when to plan construction. Fort Wagons still need a safe site and the resources required to place their structure; the technology does not instantly create a completed Fort or protect an exposed wagon.
