Tips


Tip: Once your borders have been extended, be sure to smash your guard towers on the interior of your realm to recover the resources and get your soldiers into action. 
Tip: Keep an eye on your tool stocks and shut off your weapon maker immediately when they get low. 
Tip: Always have two woodcutters and two sawmills for every forester or you'll quickly find yourself buried in trees.
