Cannon Tower

The Cannon Tower is an upgraded version of the Level 10 Watchtower. Its cannon deals AOE (Area of Effect) damage to all ground troops within range, though it cannot hit targets that are too close (within a few spaces.)

It is the perfect tower to take out many units on the ground, but it cannot targetflying units. Note that the Cannon Tower has the highest range of all defensive buildings (without garrison).

Cannon Tower is super effective in Here Be Monsters A, B and C because of ground-only enemies. From D to J, Cannon Towers becomes useless due to flying units sets on every waves..

Due to the minimum required range, placing Cannons in the center of the base is better than the corners to avoid ground units staying too close to Cannons.

Being unable to hit flying units makes Cannon Tower the most underrated tower in the game. If there are chances of meeting a base full of Arrow, Magic, and Cannon Towers, Arrow Tower would be 98%, Magic Tower 1.5% and Cannon 0.5%.

Garrison in depth

Unlike Arrow Tower and Magic Tower, Cannon’s projectile hits the ground, not the enemies. In fact, it hits the ground where the targeted enemies stand right at the time the Cannon makes a fire. The further away the enemies are from the Cannon, the longer time the projectile flies and hits the ground. Within this moment, if the enemies leave the spot, Cannon’s attack will miss.

Each attack that Cannon fires will hit 8~22 enemies, depending on the area splash range (green garrison). This also helps Cannon’s projectile to miss less often, due to enemies moving away from a projectile’s target area after they’ve been fired.

In respects to targeting, Purple garrison on Cannon works the same as a single projectile. All consecutive shots will follow the first one and hit the specified target spot. If the first one misses the targets, all following shots will miss as well. This requires heavy enough green garrisons to cover enemy movement speed, or good tank buildings such as Guild Hall and Heroes Altar to make the enemies stand at a spot long enough for Cannon to attack.

Purple garrisons produce more damage than blue garrisons, when comparing even garrison levels.
