Turret

A turret, also called a tower, is a heavy fortification that blocks the enemy's minion waves and champions' path to the nexus. Turrets are one of the core components of League of Legends. They deal damage to enemies and provide vision and general control of the battlefield to their team. Champions must destroy enemy turrets to push their assault into the enemies' territory. Turrets deal heavy damage to enemy units, but they only target one unit at a time. Turrets visually fall apart as they take damage.

There are 11 turrets per team on Summoner's Rift, 7 on Twisted Treeline, and 4 on Howling Abyss.

General Information

The following information is for Summoner's Rift turrets.

Turrets have 1095 sight range, 775 attack range and deal physical damage. They grant their team true sight, allowing it to see all traps and stealth units within their vision range.

There are four kind of turrets depending on their location:

• Outer towers: Located in front of the inner towers.
• Inner towers: Located in front of the inhibitor towers.
• Inhibitor towers: Located in front of each inhibitor, guarding the entrances to the base.
• Nexus towers: Located in front of the nexus, there are two of them.

Towers can only be targeted and damaged if they are the first structure standing in their lane. Turrets located behind the first standing structure are invulnerable and untargetable until the first one is destroyed. Inner towers only become vulnerable when their outer tower is destroyed, and inhibitor towers only become vulnerable when their inner tower is destroyed. Nexus turrets are invulnerable and untargetable until at least one inhibitor is destroyed. If a turret is destroyed while one of its shots is in mid-flight, that shot will not deal damage. Turret shots travel at a speed of 1200.

Aura effects do not affect turrets.

Turrets count as terrain, even after they are destroyed. Any abilities that interact with terrain, such as Vayne's Condemn or Poppy's Heroic Charge, can be used on them.

The first turret killed yields 150 total bonus gold split between nearby champions.

Turrets deal modified damage to minions.

Turret Passives/Items

Turrets have a pseudo-inventory that can be viewed, with each pseudo-item explaining a specific turret mechanic.

[[File:Template:Tip data/Fortification|20px|link=Template:Tip data/Fortification]][[File:Template:Tip data/Fortification|20px|link=Template:Tip data/Fortification]][[File:Template:Tip data/Fortification|20px|link=Template:Tip data/Fortification]] [[:Template:Tip data/Fortification|Fortification]]

• Unique Passive - Fortification: 50% damage reduction from all sources, this effect expires after 5 minutes. (Reduction applies before armor.)

Penetrating Bullets

• +30% armor penetration.
• Unique Passive - Dodge Piercing: Turret attacks can not be dodged, except by spells where a champion becomes untargetable.
• Unique Passive - Warming Up: Turrets gain 40% damage each time they strike a champion, up to 120% bonus damage.
  • This effect doesn't reset when switching targets.

[[File:Template:Tip data/Reinforced armor|20px|link=Template:Tip data/Reinforced armor]][[File:Template:Tip data/Reinforced armor|20px|link=Template:Tip data/Reinforced armor]][[File:Template:Tip data/Reinforced armor|20px|link=Template:Tip data/Reinforced armor]] [[:Template:Tip data/Reinforced armor|Reinforced Armor]]

• 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 ( Tibbers, Voidlings), traps ( Shaco's Jack in the Box), and monsters (brought by Syndra's Force of Will) do not deactivate this passive.

[[File:Template:Tip data/Warden's eye|20px|link=Template:Tip data/Warden's eye]][[File:Template:Tip data/Warden's eye|20px|link=Template:Tip data/Warden's eye]][[File:Template:Tip data/Warden's eye|20px|link=Template:Tip data/Warden's eye]] [[:Template:Tip data/Warden's eye|Warden's Eye]]

• Unique Passive - True Sight: Can see invisible units within 1000 units.

Attack Prioritization

Turrets will continue to attack their current target until the target dies, leaves attack range, or becomes untargetable due to abilities or items.

A turret will prioritize an enemy champion if that champion deals damage to an allied champion who is within 1400 range of the turret. Damage dealt can come from any source (pet, aura, item, etc.) in order for a champion to be targeted. Additionally, turrets will target an enemy champion if no other valid target is within range. Turrets will not attack an enemy champion who uses a non-damaging spell (e.g. Karthus' Wall of Pain). A spell or attack that is blocked (by a spell shield or ability effect) and deals no damage will still draw turret aggro.

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:

1. The closest Zz'Rot Portal.
2. The closest targetable Trap (e.g. Jack in the Box).
3. The closest enemy Pet (e.g.  Summon Tibbers).
4. An effectively random enemy siege minion or super minion.
5. An effectively random enemy melee minion.
6. An effectively random enemy caster minion.
7. The closest enemy champion to the tower.

Strategy

Turrets can create a choke point for traps such as Caitlyn's Yordle Snap Trap, especially in the smaller area closer to the wall, as minions will not normally walk through that area of the lane.

On Summoner's Rift, 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.

Damaging Turrets

Turrets can only be damaged by basic attacks, with basic attack modifiers (excluding critical strikes) fully applied unless otherwise stated. There can be special circumstances of ability damage towards turrets, such as Explosive Charge or Satchel Charge.

Damage to a turret is based on  base attack damage plus the higher of bonus attack damage or 60% of  ability power. When your attacks trigger Ability Power damage conversion (occurs when attacking a turret while your AP is more than double your bonus AD), the whole attack converts to magic damage instead of physical. Turrets are vulnerable to  armor penetration and  magic penetration.

• Draven's passive will also grant him 1 stack for last hitting a turret and count towards the 6 he needs for 2 bonus stacks.
