The Tower will throw bombs, just like the Bomber, to any enemy cards in its defensive radius. However, it cannot attack air units.
The thrown bombs have an area damage effect, perfect against swarming units with relatively low health such as Skeleton Army and Barbarians.
It is very effective against a swarm of low hitpoint ground troops, such as the Skeleton Army.
It is also very useful against cycle decks as many of the cycle card has low health which the Bomb Tower makes short work of.
The Bomb Tower can be effectively placed in the radius of the player's Tower, as it will attract most enemy troops and any opposing offensive troops attacking the Bomb Tower will be targeted by the defending Arena Tower.
Keep in mind that the Bomb Tower cannot attack air units. This means that Minions can take it out without taking damage.
The Bomb Tower is a very effective counter against the Hog Rider + Barbarians push; it will attract the Hog Rider, kill the Barbarians with its splash damage, and delay the Hog Rider as it has good hitpoints.
As with any defense, it is not wise to play the Bomb Tower in the beginning of the match or to play it proactively. This will allow the pig push technique to ignore the Bomb Tower, or, if a Golem is deployed in the back, the lifetime on the Bomb Tower will have depleted so that the Golem can kill it with one swing, barring the levels of the Tower and the Golem.
The Bomb Tower can counter Elite Barbarians due to its splash damage and high health, but this will leave the Bomb Tower either destroyed or heavily damaged.
Due to the Bomb Tower's relatively high attacking delay, very fast troops can evade a bomb while in motion.
The Bomb Tower's high health and moderate damage per second mean that if timed correctly, the Bomb Tower can take out a Royal Giant.
Bomb Towers are also capable of distracting and/or destroying troops that have medium health, including the Mini P.E.K.K.A., Knight, and Valkyrie, due to its high damage per second and fast hit speed.
