Research · collegium

Every town learns its own.

Advances are studied in a town’s collegium, paid for from that town’s stores, and known in that town alone. A collegium studies one at a time, and the advances it masters decide which troops its Castra can drill.

Cheap next to the buildings, but every town pays it again, and a collegium busy with one advance cannot start another.

How the collegium works

Opening

The Curia at level 3

A town cannot found its collegium until its Curia reaches level 3. Most towns get there early: it is the door to recruiting.

One at a time

Each collegium studies a single advance

The cost is paid from the town’s stores when the study begins, and the next can start the moment it is done.

Town by town

What a town learns, it keeps to itself

An advance unlocks what it unlocks in that town alone. Want legionaries in three towns? Three collegia study Discipline.

Conquest

Take a town, take its learning

A rival town you capture keeps what its engineers knew. Neutral towns have never had a collegium, so they come with nothing.

On the town map, the collegium’s label counts what it knows: Collegium 1/6 is a town with one advance studied and five to go.
