Adv. Lumber Mill

Benefit
Lumber Mills turn your stockpile of Wood into Lumber. The Advanced Lumber Mill obviously does this at a higher rate of production. Lumber isn't as required of a resource when compared to Concrete or Steel, but players will want to keep their reserves full and plentiful, especially if they plan on promoting Critter units, such as the Battle Raptor or Imperial Boar, or upgrading buildings to very high levels.

Refer to the Lumber Mill for more information on how  Lumber is used.
