The Strength Drain Aura reduces the damage inflicted both to towers and players by monsters within its range to the percentage shown. It costs 60 mana and 5 DU. As of patch 7.30 (PC), Strength Drain Auras also temporarily remove elemental affinity of any enemies within its range.
This aura is generally not required on Easy/Normal/Hard difficulties where tower health is sufficiently high; on earlier levels there are usually far better uses of 5 Defense Units. On Insane or Nightmare difficulty, however, this aura can protect melee range towers such as Spike Blockade, Bouncer Blockade and Slice N Dice Blockade from the stronger monsters.
|Level||Health||Effective Range||Enemy Strength||Mana To Upgrade|
- 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.
