Outpost is used for scouting, alerting around nearby territories, scouting on other territories, and attacking on nearby approaching enemy troops.
Without Outpost established : Players will not be able to detect any inbound invasion movement. After Outpost established : It will detect any inbound invasion movement. After Outpost upgrades are done : Scouting, Alerting, and Defense abilities will increase.
If outpost can provide offensive power, wooden palisade can provide defensive power. Players can always check the durability of the wooden palisade from its window and repair the durability by executing “Repair” command in the window.
Once wooden Palisade’s upgrade level increases, it will become Stone Wall > Massive Stone Wall > Forged Wall which its defensive power will significantly increase against inbound invasions.
