The Ethereal Spike Trap ("Thunder Spike Trap" in DD Awakened) is a Huntress/Ranger defense. It skewers the single enemy closest to the trap's center for high Lightning damage. This trap can 1-shot ogres on Easy/Medium difficulty.

When positioned close together, multiple of these traps will detonate in one trigger. Large enemies such as ogres can therefore be hit multiple times by a single trigger for massive damage, assuming the target is in range of each individual trap.

This is the only form of trap that can detect wyverns, goblin copters and other flying enemies.

  • 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).
