“The main purpose of a watchtower is to provide a high, safe place from which a sentinel may observe the surrounding area. Sometimes it is also a part of the communication system. Famous examples are fortifications like Hadrian’s Wall in Britain and ancient China’s beacon towers. ”
Watchtower is a great defense building that will help you to deal more damage to the enemy.
Watchtower haves Health. The health of watchtower is not great so if your city gets attacked by max rally your watchtower will be destroyed very fast.
To upgrade watchtower you will need a lot of Arrows of Resistance.
Arrows of Resistance you can get by farming barbarians, Lohar event and by spending gems.
I would not recommend you to spend gems on arrows of resistance.
How to spend gems in Rise Of Kingdoms you can see in our guide about spending gems.
Upgrading Watchtower to level 25 is needed to unlock Tier 5 Units.
