Upgrade Icon
The Upgrade Defense icon allows players to upgrade a nearby Hero Defense. It is accessed from the Action Wheel.

Because each upgrade costs more than the previous one, a level 60 or greater hero is required to upgrade a tower to its maximum level.

Upgrade Level Mana Cost Required Hero Level
TowerUpgraded 1 100 4
TowerUpgraded 2 200 9
TowerUpgraded 3 400 19
TowerUpgraded 4 700 34
TowerUpgraded 5 1220 60

Notes

  • When playing the Barbarian, the icon gives player's access to his Battle Stances.
  • 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).
