Backdoor Protection

Play

Ability
Passive / Aura

Affects
Self

Structure takes reduced damage, and quickly regenerates any damage taken while no enemy creeps are nearby.

Search Radius (Tier 2 Tower): 900

Search Radius (Ancient): 4000

Heal per Second: 90

Damage Reduction: 40%

Protected Illusion Damage Reduction: 75%

Unprotected Illusion Attack Damage Reduction: 60%

Reactivation Delay: 15

Aura Linger Duration: 0.5

Modifiers

Backdoor Protection Active: Undispellable.

Notes:

• All buildings, except for tier 1 towers and shrines have this ability.

• Tier 2 towers have a search radius of 900 centered on them, each of them independent from each other.

• The base buildings depend on the Ancient's search radius of 4000 centered on it. This means they all lose the protection together.

• The unit detection is aura-based. If an enemy lane creep gets within the search radius of the tower/ancient the protection is lost.
  • The aura's effect lingers for 0.5 seconds, so the total reactivation delay is effectively 15.5 seconds.

• While protected, the building takes 40% less damage from any source, and 75% less damage from illusions.
  • This includes spell damage, not only attacks, including spells cast by illusions.
  • While unprotected, the building only takes 60% less damage from illusion attacks (excluding their spells).

• If a backdoor-protected building is damaged by an enemy, it immediately starts healing back.

• Heals 9 health in 0.1 second intervals, which translates to 90 health per second.
  • This means, it is possible to destroy protected buildings by dealing more than 90 damage per second (after reductions).

• Only heals back damage dealt by enemy units. Damaged dealt by allies is not healed back.

True Sight

Ability
Aura

Affects
Enemies

Adds the ability to see invisible units and wards to any allied vision within the structure's range.

Radius: 900

Modifiers

Notes:

• The True Sight is provided within the whole area, regardless of the buildings actual vision. It is fully unobstructed.

• The True Sight is provided by an aura which affects enemies. Its debuff lingers for 0.5 seconds.

• Cannot detect units under the effect of Shadow Dance, Smoke of Deceit, and Techies' traps and mines within the aura of Aghanim's Scepter upgraded Minefield Sign.
