The Gas Trap is a Huntress/Ranger defense. It engulfs enemies in coughing gas, stunning weaken foes for the duration. It does not affect enemies immune to poison or any of the following enemies (regardless of their elemental affinity):

When placed on a narrow path or doorway, the enemies effected by this trap can completely block the path, preventing anything from passing through, including foes unaffected by the trap. Combined with any defense or weapon capable of hitting multiple targets at once, this can be a very powerful trap.

On Nightmare difficulty, this trap is very useful against the Sharken and Djinn, protecting other defenses from getting pushed or destroyed instantly.

Gas Trap stun duration scales up with Defense Base HEALTH stat. The Defense Base Damage stat does NOT affect the Gas Trap in any way.

  • Upgrading a hero defense increases its damage by 10% each level, and its health, lifespan or detonation count by 20% (a level 5 defense will deal 50% more damage and have 100% more health than a defense with no upgrades).
  • 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 gets a bonus of +2 to all stats, while a level 5 turret gets +36.
  • While the hero who summoned the tower is active, its damage is increased by 33% (PC).
