The Bowling Ball Turret, sometimes called the cannon, is the fastest ranged Squire / Countess tower. It also has the longest range of any Squire / Countess tower. The downside is that it has the smallest cone of attack, and the ball has to roll making it impossible to hit air units, fire uphill, or cross uneven terrain. When the ball impacts a target, it will knock it back and bounce off to continue rolling and potentially hit another target.


On flat or downhill terrain, this turret is very effective at blocking bottlenecks; the knockback effect makes it work like barricades but often without taking damage. Since it has no area of effect, it is best if supported by a harpoon or other AOE turret for killing mobs. Care must be taken in placement to avoid having the balls bounce backwards, off of railings, or through other uneven terrain.

Tower range determines how far opponents may be before the cannon begins firing at them, but the distance the ball will roll once fired is unaffected by this stat. There are also limits of 6 bounces per ball and 30 balls active per turret, though these are rarely reached. Although tower attack speed can be used to increase the rate of fire, there is a cap on this once the animation hits max speed.

  • Upgrading a hero defense increases its damage by 10% each level, and its health, aura lifespan or trap detonation charge number by 20% each level. (A level 5 defense will deal 50% more damage and have 100% more health than an un-upgraded defense).
  • On the other hand, upgrading a hero defense will mean that it acts as if the Hero has a higher Defense Area of Effect and Defense Attack Rate. A level 1 turret has a bonus of 2 to all stats, while a level 5 turret has a bonus of 36 to all stats.
  • While the hero who summoned the tower is active, damage is increased by 33% (PC).
  • Current as of PC version: 7.36c.
