A Lumberjack is made by giving a Worker an axe.
In the event a it is under threat, it will return to the Town Hall, and at night or during a rainstorm will return home.
It is useful for working tree farms. Only one lumberjack should be needed, as they provide ridiculous amounts of wood in their own. It is recommended to give a lumberjack a stone axe, as it is an infinitely farmable tool and the quality of the axe does not greatly affect the chopping speed.
