Hi,

Could it be possible to get a new build : observation tower.

Aim of this new building :

• provide a way to get information about troops which are passing near the castle,
• get information like the spy reports to know the number of troops
• and also identify the castle source of this troop
• and if possible identify the destinations castle (or the list of castle which are close to the trajectory of the troops)

Extension : get the capability to intercept the troops, using the report and defining an interception point where the troops must be sent to intercept troops passing near the castle.
