Notes:

All buildings, except for tier 1 towers have this ability (although tier 1 towers have the 60% damage reduction against illusions).

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 50% 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.
