Lumber Mill

Cities cannot be sustained by mere burning and binding of faggots and twigs any more than men may live by eating raw grain or fish-scales. Hence, a dedicated facility to convert raw harvested Timber into components for the use of mankind is required: the Lumber Mill.

The Lumber Mill's main job is increasing the output of Timber produced by Logging Camps located within the radius of your Settlements. While it can do so from the beginning it is erected, the magnitude of Timber output can be increased by researching Woodworking upgrades - with a total of 3 levels. Additionally, the Lumber Mill also hosts Construction upgrades, which increase buildings' construction speed and durability. These upgrades are also vital as they help unlock a plethora of new units, particularly ships and siege weaponry.

A Lumber Mill will always require Level 1 Commerce except for the the Phrygians who begin with on in their starting city in normal scenarios, and the Mitanni who have no restrictions whatsoever.
