Turrets, also called towers, are heavy fortifications that attack enemy units on sight. Turrets are a core component of League of Legends. They deal damage to enemies and provide vision to their team, allowing them to better control the battlefield. Turrets target one unit at a time and deal heavy damage. Teams must destroy enemy turrets to push their assault into enemy territory.

There are 11 turrets per team on Summoner's Rift and 4 on Howling Abyss.

General information

Turrets have a sight range of 1350, an attack range of 750, and deal physical damage. Their shots travel at a speed of 1200. They are normally immune to all forms of crowd control except stasis. If a turret is destroyed while one of its shots is in mid-flight, that shot doesn't deal damage.

Turrets are units that are centered on impassable terrain. This terrain remains even after the turret is destroyed. Abilities that interact with impassable terrain, such as Vayne's Condemn or Poppy's Heroic Charge, interact with this terrain for both functional and destroyed turrets.

Turrets have a pseudo-inventory that contains items that grant them effects, very much like the items in the inventories of champions. Some turret mechanics are created by those items. This section lists those items and the turret mechanics they provide. Shorter descriptions of these items and effects can be seen in the game.

Unique Passive - Fortification: 50% damage reduction from all sources, this effect expires after 5 minutes.

+30% armor penetration.

Unique Passive - Dodge Piercing: Turret attacks cannot be dodged nor intercepted untargetability

Turret attacks cannot be dodged nor Unique Passive - Warming Up: The damage dealt by turrets increases by 40% each time they hit a champion

Unique Passive - Reinforced Armor: Reduces incoming damage by 66. 66 % and becomes immune to true damage when no enemy minions or Summoned Rift Herald are nearby.

This reduces the effectiveness of backdooring (pushing without minions) compared to conventional pushing. Pets, traps, and neutral monsters do not deactivate this effect.

Unique Passive - Reinforced Armor: Reduces incoming damage by 66. 66 % and becomes immune to true damage when no enemy minions or Summoned Rift Herald are nearby.

Unique Passive: Base turrets have health regeneration, but this regeneration is limited by their current health:

Current health between 67% and 100%: Regenerate up to full health.

Current health between 34% and 66%: Regenerate up to 66% health.

Current health below 34%: Regenerate up to 33% health.

Warden's Eye

Unique Passive - True Sight: Can see all units and traps (including those in stealth) within 1200 range, unless the direct line of vision is obstructed (e.g. by terrain).

Turret rewards

Destroying a turret grants two gold rewards to the team that destroys it: a global reward and a local reward.

The global reward is given to all the champions in the team.

The local reward is shared between champions that are nearby when the turret is destroyed. All the champions within 1200 range get the local reward. Champions beyond 1200 range but within 2500 range receive the local reward only if they assisted in destroying the turret.

The local reward for destroying the first turret grants 150 bonus gold.

Target selection

Turrets attack the first enemy unit that comes into their range and continue attacking that unit until it dies, leaves the attack range of the turret, or stops being targetable. When the current target is lost for whatever reason, the turret selects a new target. If several targets are in range, the turret chooses its new target following this priority list:

However, if an enemy champion deals damage to an allied champion who is within 1400 range of a turret, the turret switches targets to attack the enemy champion. The damage can come from any source, including pets. Turrets don't attack enemy champions who use non-damaging spells, like Karthus' Wall of Pain. They will however attack them if the spell or attack is blocked by a spell shield or if the attack triggers combat effects.

Damaging turrets

Turrets can only be targeted and damaged if they are the outermost structure standing in their lane. Turrets located behind the outermost standing turret are invulnerable and untargetable until the outermost one is destroyed. This means that inner turrets only become vulnerable when their outer turret is destroyed, and inhibitor turrets only become vulnerable when their inner turret is destroyed. Nexus turrets are only vulnerable if one or more of their inhibitors are destroyed.

Turrets fall apart as they take damage.

Aura effects do not affect turrets. Turrets are not valid targets to most champion abilities. Exceptions are listed in the scroll box below. Basic attacks don't apply health based damage modifiers or critical strikes, unless otherwise stated. They do, however, apply armor penetration and magic penetration.

The damage dealt to a turret with a basic attack is the sum of the base attack damage, plus the higher of bonus attack damage and 60% of ability power. If a champion has ability power greater than double the amount of their bonus attack damage, the attack's damage converts from physical damage to magic damage.

The Demolish rune helps to destroy turrets quickly. When a champion with the Demolish rune is within the range of a turret, 6 crystals appear around the turret's base. These crystals act as a countdown timer that indicates when the turret will be vulnerable to Demolish.

Summoner's Rift turrets

There are four types of turrets in Summoner's Rift:

Type Location Number Nexus turrets In front of the nexus 2 Inhibitor turrets In front of an inhibitor, guarding the entrances to the base. 3 Inner turrets In front of the inhibitor towers. 3 Outer turrets In front of the inner towers. 3

Characteristics of each type of turret

Strategy

Turrets can be used to create choke points using traps such as Caitlyn's Yordle Snap Trap

On Summoner's Rift, during the early game melee minions usually die to two turret attacks and one champion auto attack, and ranged minions usually die to one turret attack and two champion auto attacks. This information is especially useful for last hitting minions that are being attacked by a turret.

Turret Variants

League of Legends have had numerous different turrets during its history. Most were primarily used for Summoner's Rift while the remaining ones for ARAM, Twisted Treeline, and other game modes.
