Notes

• Movement includes basic movement and mobility abilities (i.e. dashes and blinks, e.g. Ezreal's Arcane Shift or Shen's Shadow Dash).
  • Ground does not impede basic movement, but existing sources will also apply a slow.
• Attacking refers to a champion's basic attacks (by default right-click).
• Abilities refers to a champion's castable spells (by default , , , and ).
• Removal refers to cleansing effects that can remove the crowd control debuff.
• Root and Ground will only interrupt channeled movement abilities.
• Airborne, Knockdown, and Stasis are the only crowd control effects that interrupt  dashes and displacements (airborne status while knocked up is not changed by stasis however).
• Crowd control applied by one's self or an ally cannot be countered in any way (neither reduced, resisted, nor removed), with the exception of self slows (e.g.  Pyke's Bone Skewer, Rammus' Defensive Ball Curl, and  Galio's Shield of Durand), which are reduced by slow resist. There are exceptions to this rule.
• Brittle is a debuff that reduces a unit's effective Tenacity by 30%. It ends prematurely when the affected unit is immobilized.
• Forced action crowd control effects end prematurely if the Source dies.
• Charm, Flee, and Taunt all individually apply the same debuff even from different ability sources.
  • Forced action effects override each other when they're applied on the same target; an ongoing forced action will end prematurely when another one is applied.
• All crowd control effects that inhibit attacking also interrupt attack windups. In terms of crowd control, unstoppable basic attacks are interrupted by polymorph only.
• All crowd control effects that inhibit casting will also disable abilities that can be recast, unless otherwise stated by the ability.
• Spell shield blocks all components of an ability, including crowd control, unless the ability itself cannot be blocked.
• Anivia's Glacial Storm is special cased to be deactivated by all forms of crowd control that interrupt channels.
• The following mobility spells are special cased to be interrupted by immobilizations:
  • Aurelion Sol's Comet of Legend
  • Rakan's Grand Entrance and Battle Dance
  • Yasuo's Sweeping Blade
  • Yuumi's You and Me!
  • Gnar's Hop bounce is prevented.
  • Quinn's Behind Enemy Lines buff is lost.
  • Shadow Assassin's Shadow Step's buff is lost.
  • Ziggs' Satchel Charge's explosion does not cause him to fly.
• Taunt is the only crowd control that could theoretically break stealth, as the status effect is interrupted by declaring attacks.

Airborne

EditA unit is made airborne alongside undergoing a forced displacement in a specified direction or to a specific point or for a set duration at its current location. For the duration, the unit is also stunned, becoming unable to control its movement, declare attacks, cast abilities, activate items or use the summoner spells Flash, Teleport, Hexflash, and Mark / Dash.

Interrupts:	The accompanying stun interrupts attack windups (exception: unstoppable basic attack) and all channeled and charged abilities. The accompanying displacement interrupts all dashes and overrides previous airborne effects.
Reduction:	The duration of airborne and its forced movement execution time is unaffected by Tenacity.
Resist:	Resisted by crowd control immunity and displacement immunity.
Removal:	The forced movement that comes with airborne effects cannot be removed by cleansing effects. However, Cleanses can be used to remove the underlying stun, allowing the user to cast abilities and spells only (moving and attacking are still disabled): a dash or blink ability can be used to overrule the forced movement. Note that Cleanse and Mikael's Crucible, specifically, cannot be used to do this.

To expand upon the countering of airborne effects, consider that the effects are made up of two components: a movement modifier (called a "move block" by Riot, referring to a chunk of code) and a stun (which is responsible for disabling the actions of attacking and casting). As a general rule, the most recent move block will over-rule any previous move blocks, which is how Alistar's Headbutt and Pulverize combo functions. This rule also extends to all beneficial movement modifiers, such as dashes and blinks, which is why Rocket Grab and Rocket Jump will over-rule each other depending on their order of activation. Most beneficial movement modifiers do not prevent the activation of abilities, allowing Tristana to still activate abilities during Rocket Jump but not during Rocket Grab.

• In some instances, the stun duration is longer than the move block (e.g. Sion's Unstoppable Onslaught), but in most cases they are the same duration. There have been cases in the past where the stun duration was shorter, but this usually lead to bug-like interactions and was later "fixed" (e.g. Azir's Emperor's Divide did not apply any stun at all in the initial charge on the ability, which allowed his enemies to use an instant movement ability to supersede the charge's knockback and get over the wall).

Knock Aside

• The target is made airborne in a direction perpendicular from the source.
• Champions with knock aside: Corki, Draven, Urgot (minions and monsters only), Taliyah, Vi.
• Monsters with knock aside: Rift Herald.

Knockback

• The target is made airborne in a direction directly away from the point of cast.
• Champions with knockback: Aatrox (champions and large monsters), Anivia, Alistar, Aurelion Sol, Azir, Camille, Fizz, Gnar, Gragas, Graves (minions and monsters only), Hecarim, Janna, Jarvan IV, Jayce, Kled, Lee Sin, Maokai, Ornn, Poppy, Quinn, Rammus, Shyvana, Syndra, Sion (minions and monsters only), Taliyah, Thresh, Tristana, Trundle, Vayne, Vel'Koz,  Vi,  Xin Zhao, Yorick, Zac,  Ziggs.
• Monsters with knockback: Baron Nashor, Dragon, Rift Herald.

Knockup

• The target is made airborne on the spot.
• Champions with knockup: Aatrox, Alistar, Blitzcrank, Braum, Cho'Gath, Fizz, Galio, Ivern, Janna, Jarvan IV, Kalista, Lee Sin, Lulu, Malphite,  Nami,  Nautilus, Ornn, Poppy, Rakan, Rek'Sai,  Riven, Rhaast, Samira, Sion, Sejuani,  Taliyah, Vel'Koz, Vi,  Wukong, Xin Zhao, Yasuo, Yone, Zac, Zyra.
• Monsters with knockup: Baron Nashor.

Pull

• The target is made airborne in a direction toward the point of cast, and in some cases over the point of cast.
• Champions with pull: Aatrox (champions and large monsters), Blitzcrank, Darius, Diana, Kled, Orianna, Mordekaiser, Nautilus, Pyke, Sett, Singed, Sion, Skarner, Syndra (minions and monsters only), Thresh, Urgot, Vi (non-champions only), Yone.

Blind

EditA unit that is blinded will miss their basic attacks for the duration, comparable to attacking a target that is able to dodge or block, but not mechanically similar. Missed attacks will fail to deal damage or apply on-hit effects, with the exception of some empowered basic attacks. Blind does not prevent the unit from declaring attacks, unlike Disarm.

Note: Blind causes Graves' shotgun to fire pellets with a random spread, excluding the direction of his target.

Interrupts:	Does not interrupt any abilities, but will prevent on-hit effects from being triggered unless otherwise stated.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity.
Removal:	Removed by Cleanses with the exception of Mikael's Crucible.

• Champions with blind: Teemo
• Thornmail's passive deals damage before the attack is reduced by any effect, including blind, meaning it will apply even if the attacker is blinded.
• Blinded enemies will only miss if the attack is declared while blinded; ranged units still hit if the projectile fires before the blind.

Cripple

EditA unit that is crippled has reduced  attack speed for the duration.

Interrupts:	Does not interrupt any abilities.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity, Master Yi's Highlander, and Sejuani's Fury of the North.
Removal:	Removed by Cleanses and specifically Master Yi's Highlander.

• Champions with cripple: Fiora, Malphite, Nasus
• Items with cripple: Frozen Heart, Randuin's Omen, Thornmail, Warden's Mail

Disarm

EditA unit that is disarmed is unable to declare basic attack commands for the duration.

Interrupts:	Interrupts basic attack windups with the exception of unstoppable basic attacks.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity.
Removal:	Removed by Cleanses with the exceptions of Yone's Soul Unbound (recast) and Mikael's Crucible.

• Champions with disarm: Amumu, Lulu, Quinn (non-champions only).
  • Reloading is mechanically similar to being disarmed, which is featured on Graves and Jhin, but is considered a lockout.

Disrupt

EditWhen a unit is disrupted, it has their channeled and charged abilities interrupted. Unlike Silence, the unit can still cast abilities.

Disrupt is not, and does not apply, a status effect.

Interrupts:	Interrupts all channeled and charged abilities.
Reduction:	The effect is instantaneous. There is nothing to reduce.
Resist:	Resisted by crowd control immunity.
Removal:	The effect is instantaneous. There is nothing to remove.

• Champions with disrupt: Kassadin, Viktor, Camille

Forced action

Charm

For the item, see Faerie Charm

EditA unit that is charmed is forced to move directly toward the Source (the unit that casted the Charm spell) for the duration, during which they're unable to perform issued movement commands, declare attacks, cast abilities, activate items or use the summoner spells Flash, Teleport, Hexflash, and Mark / Dash. All charms also apply a slow.

Interrupts:	Interrupts attack windups ( unstoppable basic attack exception) and all channeled and charged abilities.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity.
Removal:	Removed by Cleanses or when the Source dies.

• Champions with charm: Ahri, Evelynn, Rakan.

Fear / Flee

EditA unit that is fleeing or feared is forced to move directly away from the Source (the unit that casted the Fear spell) for the duration, during which they're unable to perform issued movement commands, declare attacks, cast abilities, activate items or use the summoner spells Flash, Teleport, Hexflash, and Mark / Dash. All fears also apply a slow.

Interrupts:	Interrupts attack windups ( unstoppable basic attack exception) and all channeled and charged abilities.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity.
Removal:	Removed by Cleanses or when the Source dies.

• Champions with flee: Aatrox (non-champions only), Darius (non-champions only), Fiddlesticks, Hecarim, Nocturne, Shaco, Urgot, Warwick.

Note that, while Fear is now synonymous with Flee, it is technically still the name of a now-deprecated form of Crowd Control that had the target move around aimlessly.

Taunt

EditA unit that is taunted will attempt to perform basic attacks on the Source (the unit that casted the Taunt spell) for the duration, during which they're unable to perform issued movement or attack commands, cast abilities, activate items or use the summoner spells Flash, Teleport, Hexflash, and Mark / Dash.

Interrupts:	Interrupts all channeled and charged abilities.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity.
Removal:	Removed by Cleanses or when the Source dies.

• Champions with taunt: Shen, Rammus, Galio.

Ground

EditA unit that is grounded is unable to activate mobility spells for the duration, which include all active dash and blink abilities - including summoner spells Flash, Teleport, Hexflash, and Mark / Dash, plus a number of additional cases. Ground does not disable nor interrupt Recall and Empowered Recall. This effect does not innately knockdown a target that is already performing a dash. Grounded units can still be displaced.

Ground is the only type of crowd control that is most commonly found in persistent area of effects, which will reapply the status effect continously.

Interrupts:	Interrupts movement channels unless otherwise stated.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity.
Removal:	Removed by Cleanses with the exceptions of Yone's Soul Unbound (recast) and Mikael's Crucible.

• Champions with ground: Cassiopeia, Poppy, Singed.

Knockdown

EditKnockdown only affects units that are performing a dash or being displaced by an airborne effect. A unit that is knocked down has its dash or displacement interrupted and is placed on the ground instantly.

Knockdown is not a status effect.

Interrupts:	Interrupts all dashes and airborne effects (displacement and status effects). Knock ups will not have their airborne status removed if there is no sourced debuff, but their displacement still ends.
Reduction:	The effect is instantaneous. There is nothing to reduce.
Resist:	Resisted by crowd control immunity and displacement immunity.
Removal:	The effect is instantaneous. There is nothing to remove.

• Champions with knockdown: Ahri, Amumu, Jinx, Lissandra, Malzahar, Sejuani, Veigar, Viktor, Warwick.

Nearsight

EditA unit that is nearsighted has their sight radius reduced and loses their allied and other external vision (i.e. their ability to see what their allies see; wards and traps; abilities that grant vision) for the duration. This means it prevents unit-targeted effects, such as basic attacking, from being used outside of the unit's reduced sight radius, requiring the unit to have personal vision of their target. True sight and unobstructed vision do not infiltrate nearsight.

Interrupts:	Interrupts target commands if the nearsighted unit's target is outside of their new vision area and prevents automated target acquisition.
Reduction:	The duration is unaffected by Tenacity.
Resist:	Resisted by crowd control immunity with the exceptions of Fiora's Riposte and Morgana's Black Shield.
Removal:	Removed by Cleanses with the exceptions of Yone's Soul Unbound (recast), Cleanse, and Mikael's Crucible.

• Champions with nearsight: Graves, Nocturne, Quinn.
  • The following abilities from said champions apply nearsight:
    • Quinn's Blinding Assault reduces sight radius of the enemy target to 330 units.
    • Nocturne's Paranoia reduces sight radius of enemy champions 「 to 1,030 units. 」「 by 320 units. 」
    • Graves' Smoke Screen reduces sight radius of enemies inside the bubble to 250 units oriented to the center, but grants them vision of the entire smoke bubble.
      • Resisting and removal effects will only apply to the loss of shared vision from this ability. Enemies outside Smoke Screen cannot see through its area of effect and vice versa by any means. This is not a status effect.
• The allied portrait icons do not update while nearsighted unless an ally dies; the health, resource, level, and ultimate indicators do not change from at the time of being nearsighted initially. This also applies to the tab view for seeing the item inventory for all champions in a match.
• Multiple applications of nearsight debuffs will only consider the one with the greatest sight reduction.
• Since sight is shared, allies will not be able to see further than their nearsighted ally's sight radius. This vision can still be effectively granted by other allies near the affected ally, in which case some, or all, of the lost vision is recovered.

Silence

EditA unit that is silenced cannot cast abilities, activate items nor use the summoner spells Flash, Teleport, Hexflash, and Mark / Dash for the duration.

Silence is also a general term used to refer to crowd control effects that inhibit the casting of abilities.

Interrupts:	Interrupts all channeled and charged abilities.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity.
Removal:	Removed by Cleanses with the exception of Yone's Soul Unbound (recast).

• Champions with silence: Blitzcrank, Cho'Gath, Fiddlesticks, Garen, Malzahar, Soraka

The following crowd control types combine silence with additional effects:

• Polymorph
  • Champions with polymorph: Lulu

Sleep

Drowsy

EditA unit that is drowsy is gradually slowed over the duration, and will fall asleep thereafter.

Removing drowsy or being displacement immune or immune to crowd control at its end will prevent sleep from occurring. Activating a spell shield or becoming untargetable does not.

Interrupts:	Drowsy does not interrupt any actions.
Reduction:	The duration of drowsy is unaffected by Tenacity.
Resist:	Resisted by crowd control immunity.
Removal:	Removed by Cleanses.

• Champions with drowsy: Lillia, Zoe.

EditA unit that is asleep is unable to control its movement, declare attacks, cast abilities, activate items or use the summoner spells Flash, Teleport, Hexflash, and Mark / Dash for the duration. Sleep occurs after the duration of drowsiness finishes.

Interrupts:	Falling asleep interrupts attack windups ( unstoppable basic attack exception) and all channeled and charged abilities.
Reduction:	The duration is affected by Tenacity.
Resist:	Resisted by crowd control immunity and displacement immunity.
Removal:	Removed by Cleanses and taking non- persistent damage from non- minions.

• Champions with sleep: Lillia, Zoe.

Slow

EditA unit that is slowed has reduced  movement speed for the duration. Slow percentages cannot reduce a target below  110 movement speed. Some slows will instead modify the target's movement speed to a static value, which may not be further reduced nor increased.

Only the slow with the highest value is taken into movement speed calculations. All additional slows are ignored until the higher-valued slow wears off.

Interrupts:	Does not interrupt any abilities.
Reduction:	The duration is affected by Tenacity. The strength is reduced by slow resist.
Resist:	Resisted by crowd control immunity and slow immunity.
Removal:	Removed by Cleanses (except Yone's Soul Unbound recast), Garen's Decisive Strike, Master Yi's Highlander and Nunu's Biggest Snowball Ever!.
