Healing Aura
Healing Aura
The Healing Aura is the only defensive structure capable of healing players. It does not affect towers.

It can aid in the survival of a player who intends to hold an area without the aid of defensive structures, thus saving Defense Units. It can also save mana since the healing bestowed by this aura is much more cost effective than using the self heal spell.

  • 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.



  • 7.16c: Healing Auras now cost only 4 defense units, and heal for 3x more.
