Notes

• Movement includes mobility abilities (i.e. dashes and blinks, such as Ezreal's Arcane Shift Arcane Shift).
  • Ground does not impede basic movement.
• 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).
• Spells refers to summoner spells.
• Interrupt refers to whether or not the effect will cancel channeled abilities.
  • Roots and Entangles will not interrupt channeling, with the exception of Teleport Teleport and Shen's Shen's Stand United Stand United.
  • Roots and Entangles will interrupt Vault Breaker Vault Breaker and Elastic Slingshot Elastic Slingshot by virtue of disabling their second casts.
  • Nearsight prevents the activation of "long ranged" abilities, which seems to include any ability that can input targets via the minimap. By virtue of disabling the second cast, Nearsight will interrupt Elastic Slingshot Elastic Slingshot. This may be a bug, although it is thematically appropriate for an effect that removes the target's ability to see.
  • Knockdown and Ground only interrupt dash and blink abilities.
• 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.

Airborne

A unit that is made airborne is moved in a specified direction or to a specific point. For the duration, the unit is also 20px stunned and cannot move, attack, cast abilities, activate items or use the summoner spells Flash and Teleport Teleport.

Interrupts:	Interrupts all channeled and charged abilities, as well as Glacial Storm, all dash abilities and other airborne effects.
Reduction:	Only the stun component duration is reduced by Tenacity, which stacks multiplicatively. Forced movement's execution time remains unaffected.
Resist:	Resisted by Black Shield Black Shield, Ragnarok Ragnarok, Riposte Riposte and Void Shift Void Shift, as well as dashes that grant immunity to disables.
Removal:	The forced movement of airborne effects cannot be removed by cleansing effects. However, Quicksilver Quicksilver, Mikael's Crucible Mikael's Crucible, Battle Roar Battle Roar, Ragnarok Ragnarok, Remove Scurvy Remove Scurvy and Unbreakable Will can be used to remove the stun effect. Once the user is able to activate abilities: a dash or blink ability can be used to overrule the airborne. Note that Cleanse Cleanse, 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 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 Rocket Grab and Rocket Jump 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 Tristana to still activate abilities during Rocket Jump Rocket Jump but not during Rocket Grab 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.
  • Note that Cleanse Cleanse is special-cased to not remove the stunning effects, but is still available to cast. One or the other may be a bug.
• In some instances, the stun duration is longer than the move block (e.g. Sion's Sion's Unstoppable Onslaught 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 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: Anivia, Alistar, Aurelion Sol Aurelion Sol, Azir, Camille Camille, Fizz Fizz, Gnar, Gragas Gragas, Graves Graves (minions and monsters only), Hecarim Hecarim, Janna Janna, Jayce Jayce, Kled Kled, Lee Sin Lee Sin, Maokai Maokai, Ornn Ornn, Poppy Poppy, Quinn Quinn, Rammus Rammus, Shyvana Shyvana, Syndra Syndra, Sion Sion (minions and monsters only), Taliyah Taliyah, Thresh Thresh, Tristana Tristana, Trundle Trundle, Vayne Vayne, Vel'Koz Vel'Koz, Vi Vi, Xin Zhao Xin Zhao,  Zac, Ziggs Ziggs.

• Champions with knock aside: Corki Corki, Draven Draven, Urgot Urgot (minions and monsters only), Taliyah Taliyah, Vi Vi.
• Monsters with knock aside: 20px Rift Herald.

Knockup

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

• Champions with pull: Blitzcrank Blitzcrank, Darius Darius, Diana Diana, Kled Kled, Orianna Orianna, Nautilus Nautilus, Singed Singed, Sion Sion, Skarner Skarner, Syndra Syndra (minions and monsters only), Thresh Thresh, Urgot Urgot, Vi Vi (non-champions only), Viktor Viktor, Volibear Volibear.
• Monsters with pull: 20px Vilemaw.

Blind

A unit that is blinded will "Miss" their basic attacks, similar to when attacking a target with dodge. Missed attacks will fail to deal damage or apply on-hit effects, with the exception of Rolling Thunder Rolling Thunder and Devastating Charge Devastating Charge. Unlike Disarm, Blind does not prevent the unit from declaring attacks. Blind causes Graves' 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. This does not waste the effects, however, and they will simply wait until a successful attack lands.
Reduction:	The duration is reduced by Tenacity, which stacks multiplicatively.
Resist:	Resisted by Black Shield Black Shield, Ragnarok Ragnarok, Riposte Riposte and Void Shift Void Shift. Dashes that grant immunity to disables will ignore the effects of Blind for the duration of the dash, but the target will be affected upon landing if the disable duration permits.
Removal:	Removed by Cleanse Cleanse, Quicksilver Quicksilver, Battle Roar Battle Roar, Ragnarok Ragnarok, Remove Scurvy Remove Scurvy and Unbreakable Will.

• Champions with blind: Teemo.
• Thornmail 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.

Cripple

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

Interrupts:	Does not interrupt any abilities.
Reduction:	The duration is reduced by Tenacity, which stacks multiplicatively.
Resist:	Resisted by Highlander Highlander, Black Shield Black Shield, Ragnarok Ragnarok, Riposte Riposte and Void Shift Void Shift. Dashes that grant immunity to disables will ignore the effects of Slow for the duration of the dash, but the target will be affected upon landing if the disable duration permits.
Removal:	Removed by Cleanse Cleanse, Quicksilver Quicksilver, Mikael's Crucible Mikael's Crucible, Shadow Step Shadow Step (as Shadow Assassin Shadow Assassin), Decisive Strike Decisive Strike, Highlander Highlander, Battle Roar Battle Roar, Ragnarok Ragnarok, Remove Scurvy Remove Scurvy and Unbreakable Will.

Resist:	Resisted by Black Shield Black Shield, Ragnarok Ragnarok, Riposte Riposte and Void Shift Void Shift. Dashes that grant immunity to disables will ignore the effects of Disarm for the duration of the dash, but the target will be affected upon landing if the disable duration permits.
Removal:	Removed by Cleanse Cleanse, Quicksilver Quicksilver, Battle Roar Battle Roar, Ragnarok Ragnarok, Remove Scurvy Remove Scurvy and Unbreakable Will.

• Champions with disarm: Quinn Quinn (non-champions only).

  • Tahm Kench's Devour Devour or Kalista's Fate's Call Fate's Call don't belong in here (untargetable targets can sometimes move or be vulnerable to area of effect and/or damage over time effects, which is thematically at odds with what "stasis" means).

Suspension

A unit that is suspended is made Airborne on the spot and is also 20px stunned, preventing them from moving, attacking, casting abilities, activating items or using the summoner spells Flash and Teleport Teleport.
