• Each Backdoor Protection search radius functions independently of the other.
  • The Ancient has a 4000 search radius, granting Backdoor Protection to all buildings inside the base, excluding the Fountain.
  • Since the buildings within the base are based on the Ancient's search radius, they lose Backdoor Protection at the same time as the Ancient.

• The unit detection is aura-based. If an enemy lane creep enters the search radius, the Backdoor Protection for that building is automatically disabled.
  • The aura's effect lingers for 0.5 seconds, so the total reactivation delay is effectively 15.5 seconds.

• Grants the following effects to the protected building while active:
  • Self-heals 18 health in 0.1 second intervals upon any damage instance.
  • Only heals from enemy damage sources, ally damage dealt (e.g. from denying) is not healed. It is possible to destroy protected buildings by dealing more than 270 damage per second (before reductions).
  • Applies generic incoming damage reduction on the building. Affects all damage types the building takes that is not flagged as HP removal.
    • Stacks additively with other sources of generic incoming damage manipulation.
  • Applies a unique incoming damage reduction with the incoming damage reduction of Reinforced.
    • Stacks multiplicatively with other sources of unique incoming damage manipulation. Therefore, it further reduces the incoming damage from the following units while Backdoor Protection is active:
    • EXPR
      • Against illusions attack damage: IllusionDamageDealt × 0.1
      • Against illusions spell damage: SpellDamageDealt × 0.25
      • Against summons and Dominated creeps: AttackDamageDealt × 0.225
