Mill

The Mill is your in-city resource building that produces Bread (Food) for your account. Unlike Bread gathered from resource nodes on the world map, this Bread is a secured resource that cannot be pillaged in the event that your Town loses to an opponent’s attack.

The Mill is a highly important building in the early game since it will be your main source of Bread. Increasing the building level of the Mill does not directly upgrade its efficiency, but it does allow you to build more (and higher level) Furniture within the Mill building that increases its productivity as well as provide additional slots for Resident workers. This efficiency can be further enhanced with research in the Economy research tree of the Academy building.

While the Mill’s productivity output is described in terms of “harvests”, it mathematically equates to the same base resource output speed as an equivalently invested Sawmill. Unlike other resource buildings, a small amount of bread will be continuously used to feed your residents via the Kitchen building. This is a negligible amount compared to other uses of Bread.

Just like other resource buildings, resource gathering on the world map will start to outpace in-town resource generation due to diminishing returns of additional Mill levels, usually around the mid-20s of Town Center level. While the Mill never stops being an important source of this important resource, it does mean its priority can fall slightly behind other buildings you are upgrading if you have to make tough choices.
