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.
• Impaired movement refers to crowd control effects that inhibit the unit's movement, which includes all immobilizing effects as well as Drowsy, Ground, and Slow.
• Immobilizing effects refer to crowd control effects that render the unit unable to control their movement, which includes Airborne, Forced Action ( Berserk, Charm, Flee, Taunt), Root, Sleep, Stasis, Stun ( Suspension), and Suppression.
• 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) unless otherwise stated.
  • Self- slows (e.g. Pyke's Bone Skewer, Galio's Shield of Durand, and Varus' Piercing Arrow) will be reduced by slow resist.
• 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 (excluding Berserk) end prematurely if the Source dies.
• Berserk, 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, basic attacks with uncancellable windups 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 and Samira's Inferno Trigger are special cased to be deactivated by all forms of crowd control that interrupt all channels.
• Crowd control applications trigger a stack for Electrocute and Phase Rush.
• Taunt is the only crowd control that could theoretically break stealth (due to it being interrupted by declaring an attack).

Airborne

Template:Crowd control info 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 the disabling 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 will interrupt Rocket Jump (although beneficial effects are not usually combined with a disabling effect, allowing Tristana to still activate abilities during Rocket Jump but not during Rocket Grab).

• Through the use of cleansing effects or tenacity, players can remove the stun and subsequently activate abilities such as Flash or champion-specific dashes to break the airborne's move block.
• 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 Flash/dash to supersede the charge's knockback and get over the wall).

Knockback

• The target is made Template:Cctip in a direction directly away from the point of cast.
• Champions with Knockback: Anivia, Alistar, Aurelion Sol, Azir, Fizz, Gnar, Gragas, Hecarim, Janna, Jayce, Lee Sin, Maokai, Poppy, Quinn, Rammus, Shyvana, Syndra, Taliyah, Thresh, Tristana, Trundle, Vayne, Vel'Koz,  Vi,  Xin Zhao,  Zac,  Ziggs.

Knock Aside

• The target is made Template:Cctip in a direction perpendicular from the source.
• Champions with Knock Aside: Corki, Draven, Vi.

Knockup

• The target is made Template:Cctip on the spot.
• Champions with Knockup: Aatrox, Alistar, Blitzcrank, Braum, Cho'Gath, Fizz, Janna, Jarvan IV, Kalista, Lee Sin, Lulu, Malphite,  Nami,  Nautilus, Poppy, Rek'Sai,  Riven, Sion, Sejuani,  Taliyah, Vi,  Wukong, Xin Zhao, Yasuo, Zac, Zyra.

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: Blitzcrank, Darius, Diana, Orianna, Nautilus, Singed, Skarner, Syndra (against minions and monsters), Thresh, Viktor and Volibear.

Blind

Template:Crowd control info

• Champions with Blind: Teemo
• Thornmail's passive returns 30% of all physical damage back to the attacker as magic damage before the damage is reduced by any effect, including blind. So it still applies if the target is blinded.
• Blinded enemies will only miss if they attack while blinded; ranged units still hit if the projectile fires before the blind.

Disarm

Template:Crowd control info

• Champions with Disarm: Quinn (non-champions only).
  • Reloading is mechanically similar to being disarmed, which is featured on Graves and Jhin.

The following crowd control types combine Disarm with another crowd control type:

• Template:Cctip
  • Champions with Entangle: Amumu
• Template:Cctip (aka Pacify)
  • Champions with Polymorph: Lulu.

Forced Action

Charm

"Charm" redirects here. For the item, see Faerie Charm.

Template:Crowd control info

• Champions with Charm: Ahri.

Fear / Flee

Template:Crowd control info

• Champions with Flee: Darius (non-champions only), Fiddlesticks, Hecarim, Nocturne, Shaco, Urgot and Volibear (non-champion enemies only).
  • Uniquely to Volibear, Fear causes the target to wonder around aimlessly instead of away from the source.

Taunt

Template:Crowd control info

• Champions with Taunt: Shen, Rammus, Galio.

Ground

Template:Crowd control info

• Champions with Ground: Cassiopeia.

Nearsight

An argument can be made that Nearsight is a debuff, rather than a form of crowd control, due to it not being affected by crowd control reduction nor immunity, as well as being resistant to cleanse effects. However, as the effect disables the use of some abilities and all but one source is a persistent effect (i.e. they cannot be removed or reduced anyway), it is being listed here.

Template:Crowd control info

• Champions with Nearsight: Graves, Nocturne, Quinn, Rek'Sai (self) and Tahm Kench.

Root

Template:Crowd control info

Stasis

Template:Crowd control info

• Champions with Stasis: Aatrox, Bard, Lissandra, Syndra (minions only), Zilean and Zhonya's Hourglass.
  • While Devour does make his target untargetable, the target remains vulnerable (which is thematically at odds with what "stasis" means).

Stun

Template:Crowd control info
