Please note the following:

• Movement includes abilities (such as Ezreal's Arcane Shift).
  • For example, while airborne you can cast all summoner spells except Flash and Teleport.
• Attack refers to a champion's basic attacks (by default right-click).
• Ability refers to a champion's castable spells (by default Q, W, E and R).
  • Mikael's Crucible cannot be activated where Abilities are disabled, as the item is intended to be used on allies.
• Spells refers to the Summoner Spells.
• Interrupt refers to whether or not the effect will cancel channeled abilities.
  • Contrary to popular belief, Roots and Entangles will NOT interrupt channeling. This is with the exception of two special-cases: Teleport and Shen's Stand United. Roots and Entangles will, however, interrupt charged abilities (namely Elastic Slingshot, Vault Breaker and Piercing Arrow).
• Mercurial Scimitar removes any crowd control effect that Quicksilver Sash would.

Types of Crowd Control

Airborne

• Airborne crowd control 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 to attacking and casting). In the game, the most recent move block will over-rule any previous move blocks.

• Move block
  • The target is unable to control movement.
    • The target remains targetable and will be affected by abilities as if they were on the ground (such as Miasma).
    • The duration of the effect is related to how long the target is in the air. A common bug where a target who is dashing is made airborne causes them to be knocked "into orbit". The duration is largely extended due to the increased distance the target has to fall.
  • Interrupts active move blocks, namely other airborne effects and dashes.
  • Can be interrupted by subsequent move blocks, namely other airborne effects, dashes or blinks.
  • The duration is unaffected by crowd control reduction.
  • The effect cannot be removed by cleanse effects.
• Stun
  • The target is unable to cast abilities or basic attack.
  • The duration is affected by crowd control reduction and can be removed by cleansing effects.
  • Explained in more detail below.

• 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 airborne in a direction directly away from the point of cast.
• Champions with Knockback: Alistar, Azir, Fizz, Gnar, Gragas, Hecarim, Janna, Jayce, Lee Sin, Maokai, Poppy, Quinn, Rammus, Shyvana, Syndra, Thresh, Tristana, Vayne,  Vi,  Xin Zhao,  Ziggs

Knock Aside

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

Knockup

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

Suspension

• The target is unable to control movement, attack or cast abilities.
  • The target remains targetable and will be affected by abilities as if they were on the ground (such as Miasma).
• Interrupts the channeling of abilities.
• Interrupts dash abilities.
• Unlike a knockup, which is visually similar:
  • The duration is affected by crowd control reduction.
  • The effect can be removed by all cleansing effects.
• Champions with Suspension: Nami, Vel'Koz, Yasuo

Blind

• The target will miss auto-attacks, incurring the message "Miss" above their attack target.
  • Blind only mitigates the physical damage portion of an attack, including physical damage sourced from a physical on-hit effect. Other damage types and effects won't miss. See: On-hit effects.
  • Abilities that apply on-hit effects will also miss. ( Miss Fortune's Double Up is exempt from this. *tested*)
  • Blind is considered a form of damage mitigation. As such, it is applied after Thornmail's passive.
• Does not interrupt channeling.
• The duration is affected by crowd control reduction.
• The effect can be removed by all cleansing effects (except for Mikael's Crucible).
• Blind will not affect certain champion abilities.(e.g. Riven's passive Runic Blade)
• Blinded enemies will only miss if they attack while blinded. Ranged units will still hit if the projectile fires before the blind.
• If Vayne is blinded, she can only proc her Silver Bolts if she tumbles. Normal auto attacks do not proc silver bolts while blinded (tested)
• Champions with Blind: Teemo ,  Quinn

Entangle

• The target is unable to control movement or attack.
  • This includes abilities and summoner spells that move the champion.
  • This will not prevent delayed teleports that have already begun channeling, such as Twisted Fate's Gate. The target will arrive rooted, if the duration permits.
• Does not interrupt the channeling of abilities.
• The duration is affected by crowd control reduction.
• The effect can be removed by all cleansing effects.
• Champions with Entangle: Amumu

Forced Action

• ​The target is unable to control movement, attack or cast abilities.
• Interrupts the channeling of abilities.
• The duration is affected by crowd control reduction.
• The effect can be removed by all cleansing effects.

Charm

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

• The target will attempt to move toward the source for the duration.
• If the target does not have vision of the source, they will instead stand still.
• If the source dies, the effect ends.
• Champions with Charm: Ahri

Fear

• The target will walk in random directions with reduced movement speed for the duration.
• Champions with Fear: Volibear (non-champion enemies only)

Flee

• The target will be locked in place for a brief duration and then run directly away from the source with reduced movement speed for the duration.
• Units immune to slowing effects will run away from the source with normal movement speed.
• Champions with Flee: Fiddlesticks, Hecarim, Nocturne, Shaco

Taunt

• The target will attempt to attack the source of the taunt for the duration.
• If the target does not have vision of the source, they will simply stand in place.
• If the target cannot attack the source (such as Zhonya's Hourglass), the target will simply stand in place.
• If the source dies, the effect ends.
• Champions with Taunt: Shen, Rammus, Galio

Polymorph

• ​The target is unable to attack or cast abilities and is slowed for the duration.
  • This is distinct from Blind as the target cannot attack at all: as such, on-hit effects are never used/wasted.
  • Whimsy, when cast on an enemy, transforms the target into a small critter (reducing their size).
• Interrupts the channeling of abilities.
• The duration is affected by crowd control reduction.
• The effect can be removed by all cleansing effects.

  • Will interrupt charged dashes, namely: Elastic Slingshot and Vault Breaker.
• The duration is affected by crowd control reduction.
• The effect can be removed by all cleansing effects.
