The Harpoon Turret is a large crossbow with a wide range and medium-high damage. Its ability to penetrate enemies makes it a good tower for choke points and intersections.


Tower range determines how far opponents may be before the tower begins firing at them, but once fired the harpoon will travel indefinitely, passing through enemies and crystals, but not through walls.

The Harpoon should often be protected behind a physical barrier such as the Bouncer Blockade or preferable a Spike Blockade to keep monsters at a distance.

  • 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.
