Watch Tower
The watch tower is necessary to discover
spy ships.
Without it, an isle can be spied, and the victim has no chance to identify the one who sent the ship.
With the watch tower, there is a good chance that the one who sent the spy ship is identified and the espionage
may even be blasted. For the future, it is planned that the watch tower can be armed with cannons to
strengthen the defence of the islands.
The watch tower can be upgraded to level 20, and every level increases the chance to blast enemy espionage and
to identify the one who sent the ship. However, this chance is never 100%, not even with a level 20 watch tower.
Moreover, every level yields 2 points.
