Lumber Mill Tips & Gameplay in Rise of Kingdoms

In Rise of Kingdoms, Lumber Mill plays an important role in training your troops, upgrading your buildings and researching technologies. A well maintained Lumber Mill means you will have enough resources to support your city independently.

Always keep your wood protected to avoid them being plunder by raiders. You can do so through increasing the Storehouse to further protect your wood whenever you are inactive or not watching your city.

If you are running a mini farming account, it’s good idea to max out your Lumber Mill and do these following steps to draw in additional resources for your main account.
