Fortification is adding defenses to buildings that can deal damage to troops. Once a building is fortified, it will add a 1 by 1 space to the building. Fortifications can be upgraded. Every level it gets additional damage per second. Fortification can be upgraded until what level you can upgrade your walls. Their appearance will look like the same but it will be spiked.
