A Turret, also called a Tower, is a heavy fortification that blocks the enemy's minion waves and champions' path to the Nexus. In order for a Champion to push forward and continue its assault into the enemies’ territory, the champion must destroy these turrets. Charging minions will not be able to pass any further up a lane until the turret closest to them is destroyed. Turrets do heavy damage to enemy units. Summoner's Rift has 11 turrets per team.
Turrets will continue to attack their current target until the target dies, leaves attack range, or becomes untargetable due to abilities or items.
If an enemy champion within range deals damage to an allied champion (including via damage over time or a pet), the turret will change targets to that enemy champion unless the turret is already targeting another enemy champion. The tower will not change target if the spell does not deal damage, yet applies a Crowd Control effect or debuff.
When the current target is lost for whatever reason, the turret will select a new target—whichever of the following, in order, is found in range first:
- The closest targetable Trap (i.e. Rampant Growth).
- The closest enemy Pet (i.e. Mirror Image, Hallucinate, Summon: Tibbers, Children of the Grave, Summon Voidling, H-28G Evolution Turret, Decoy, Spider Swarm, or Omen of Death).
- The closest enemy Siege Minion or Super Minion.
- The closest enemy Melee Minion.
- The closest enemy Caster Minion.
- The closest enemy Champion.
Turret healing and invulnerability
- Inhibitor turrets have 15 Health Regeneration per 5 seconds.
- The Nexus Turrets also have natural Health Regeneration. However, if inhibitors have been destroyed this far, it would be difficult to "turtle" the match by turret-hugging.
- Inner turrets are invulnerable and untargetable until the corresponding Outer turrets are destroyed. Likewise, Inhibitor turrets are invulnerable and untargetable until the corrsponding Inner turrets are destroyed, and Nexus turrets are invulnerable and untargetable unless at least one inhibitor is destroyed.
- Turrets deal 70% damage to siege minions and super minions .
- Turrets first attacks on champions deal 105% damage .
- The Nexus Obelisk deals a flat 1000 damage every 0.5 seconds, ignoring all damage reduction and resistance.
Damage from the other turrets is mitigated by your armor - minus the Armor penetration due to the Penetrating Bullets passive.
Passives described by the Turret's Inventory items
Turrets have an item inventory that can be seen by clicking on them. Each item in the inventory explains a specific turret mechanic.
- Reinforced armor
- +60 Armor and +100 Magic resist
- Unique passive - Backdoor plating : Gains 150 Armor and 150 Magic resistance when no enemy minions are in range for attack. This makes backdooring less effective than conventional pushing. It is not tested whether traps (Shaco's Jack in the box), pets (Annie's Tibbers or Yorick's ghouls) and monsters (a Golem brought around by Syndra's Force of Will) deactivate this passive too.
- Penetrating Bullets
- +30% Armor Penetration
- Unique passive - Dodge Piercing : Turret attacks can not be dodged
- Unique passive - Warming Up : Turrets gain 25% damage each time they strike a champion (Max 75% bonus damage). It should be noted that this passive is not champion-specific, meaning it keeps stacking even when switching between champions. In other words, it resets only when attacking a non-champion (pet, minion or monster).
- Unique passive - Heated Up : After the turret is fully heated, consecutive attacks against the same champion deal 25% additional damage (Max 50% bonus damage).
Both Warming Up and Heated Up bring a total of 105% damage on the first hit, then 125%, 150%, 175%, 200%, and up to a maximum of 225% on the sixth hit and beyond. If the turret attacks another champion, only Heated Up stacks will be reset, and the damage will stay at 175%. If a non-champion (pet, minion, monster, trap...) is hit, both passives reset and damage returns to 105%.
- Warden's Eye
- +1000 vision radius
- Unique passive - Magical Sight : Can see invisible units
Turrets have 1095 sight range and 775 attack range.

(* Estimated values )
(** That can be checked only on spectator mode as Nexus Obelisk is untargetable while playing. As mentioned above, the damage dealt is true damage. )
(*** See last point in the chapter below for damage reduction)
- Damage to a turret is based on your base attack damage plus the higher of your bonus attack damage or 40% of your ability power. It is not affected by any kind of armor or magic penetration .
- Critical strikes will register against turrets. However, they are not affected by them, and no bonus damage will be incurred.
- Top and middle lane outer turrets have 20 damage reduction from champion basic attacks since V4.1. The phrasing in the patch notes makes it ambiguous whether this is permanent or happens only during the first 8 minutes of the game; feel free to test and update.
