Debuff

Tristana OriginalSquare Tristana under the effects of Nasus OriginalSquare Nasus' Wither Wither

Crowd control (commonly shortened to CC) is a blanket term used in League of Legends to describe abilities or spells that remove or diminish the control a target unit has over aspects of itself - aspects such as being able to cast spells or initiate movement commands. As crowd controls impact a unit's combat ability, they are essentially more specialized forms of debuffs - however, this ability to directly hinder a unit's ability to fight means that crowd controls are often given significantly more importance in regular gameplay than normal debuffs, resulting in their special classification.

There are many different forms of crowd control, each of which is unique in the way it affects its target and the ways it can - if at all - be resisted, mitigated or removed. Some crowd controls can be exclusive or near-exclusive to certain champions or items, and different champions can apply the same crowd control in multiple different ways. A few specific mechanics (such as Yasuo OriginalSquare Yasuo's Last Breath Last Breath) even require a catalyst crowd control to function.

All crowd controls, at the exception of Blind icon Blind or Cripple icon attack speed slow, even the ones without any damage, will count toward assists.

Types of Crowd Control

For the complete article, see Types of Crowd Control.

The following are the current forms of crowd control that exist within League of Legends:

  • Airborne icon Airborne: A unit that is airborne is unable to control its movement, attack or cast abilities for the duration.
    • Knock aside: A knock aside causes the target to be made airborne in a direction perpendicular to the direction of cast.
    • Knockback: A knockback causes the target to be made airborne in a direction away from the point of cast. The duration depends on how far the target travels, from 0.75 seconds (Rammus OriginalSquare Rammus' Powerball Powerball) to 1.5 (Lulu OriginalSquare Lulu's Wild Growth Wild Growth).
    • Knockup: A knockup causes the target to be made airborne on the spot. The duration depends on how high is the target thrown into the air, from 0.75 seconds (Rammus OriginalSquare Rammus' Powerball Powerball) to 1.5 (Lulu OriginalSquare Lulu's Wild Growth Wild Growth).
    • Pull: A pull effect causes the target to be made airborne in a direction toward the point of cast.
  • Blind icon Blind: A unit that is blinded will miss its basic attacks for the duration. Miss occurs on-hit, and does not prevent attacks from being declared.
  • Disarm icon Disarm: A unit that is disarmed cannot declare attacks for the duration.
  • Silence icon Polymorph: A unit that is polymorphed is Silenced and turned into a critter. All basic attack windups (including Excessive Force 2 unstoppable basic attack ones) are cancelled. The only example also disarms and reduces movement speed for the duration.
  • Forced Action: A unit that is under the effect of a forced action cannot control its own movement or attacks, and is unable to cast abilities.
    • Charm icon Charm: A unit that is charmed will move toward the source for the duration.
    • Flee icon Fear: A unit that is feared move around randomly at reduced movement speed for the duration. There are currently no examples of this type that affects champions.
    • Flee icon Flee: A unit that is fleeing will move directly away from the source with reduced movement speed for the duration.[1]
    • Taunt icon Taunt: A unit that is taunted will attempt to basic attack the source for the duration.
  • Grounded icon Ground: A unit that is grounded is unable to activate mobility spells.
  • Knockdown icon Knockdown: A unit that is knocked down is placed on the ground.
  • Nearsight icon Nearsight: A unit that is nearsighted has their sight radius reduced and loses their allied vision.
  • Root icon Root: A unit that is rooted is unable to control its movement for the duration.
  • Silence icon Silence: A unit that is silenced cannot cast abilities or activate items for the duration.
  • Drowsy icon Drowsy: A unit that is drowsy is gradually slowed over the duration, falling asleep thereafter.
    • Sleep icon Sleep: A unit that has fallen asleep is unable to move, attack or cast abilities for the duration as long as it doesn't get damaged.
  • Slow icon Slow: A unit that is slowed has reduced movement speed for the duration.
    • Cripple icon Cripple: A unit that is crippled has reduced attack speed for the duration.
  • Stasis icon Stasis: A unit that is in stasis is unable to perform any action while being Playful untargetable and Cosmic Radiance invulnerable. The duration is also unaffected by crowd control reduction.
  • Stun icon Stun: A unit that is stunned is unable to move, attack or cast abilities for the duration.
    • Stun icon Suspension: A unit affected by suspension is considered airborne and stunned. It is also modified by crowd control reduction.
  • Suppression icon Suppression: A unit that is suppressed is unable to control its movement, attacks, abilities or use spells. The duration is also unaffected by crowd control reduction.

Notes

Categorization

To facilitate easier communications, crowd controls are usually described under one of the following systems:

Loss of Control

Crowd controls are grouped into one of two categories depending on whether or not the effect removes total control of the player's character.

Total CC Partial CC
Airborne icon Airborne Blind icon Blind
Charm iconFlee iconTaunt icon Forced Action Cripple icon Cripple
Sleep icon Sleep Disarm icon Disarm
Stun icon Stun Grounded icon Ground
Suppression icon Suppression Knockdown icon Knockdown
Stun icon Suspension Nearsight icon Nearsight
Stasis icon Stasis Root icon Root
Silence icon Silence
Slow icon Slow

Disruption

Crowd controls are grouped into one of two categories depending on whether or not the effect disrupts a Channeling icon channeled ability (such as Karthus OriginalSquare Karthus' Requiem Requiem and Katarina OriginalSquare Katarina's Death Lotus Death Lotus).

Note that Silence icon Disrupt will have the same interaction as Hard disruption CC towards channels, but does not have a duration and thus is not a status effect.

Disrupts Does not disrupt
Airborne icon Airborne Blind icon Blind
Charm iconFlee iconTaunt icon Forced Action Cripple icon Cripple
Silence icon Silence Disarm icon Disarm
Stasis icon Stasis Grounded icon Ground
Stun icon Stun Knockdown icon Knockdown
Suppression icon Suppression Nearsight icon Nearsight
Stun icon Suspension Root icon Root
Sleep icon Sleep Slow icon Slow

Immobilization

Crowd controls are grouped into one of two categories depending on whether or not they restrict movement. Hard CCs prevent all forms of movement, while soft CCs do not. This is how hard and soft CC is usually defined.

Hard CC Soft CC
Airborne icon Airborne Blind icon Blind
Charm iconFlee iconTaunt icon Forced Action Disarm icon Disarm
Root icon Root Grounded icon Ground
Stasis icon Stasis Knockdown icon Knockdown
Sleep icon Sleep Nearsight icon Nearsight
Stun icon Stun Silence icon Silence
Suppression icon Suppression Slow icon Slow
Stun icon Suspension Cripple icon Cripple

Modifiers

Crowd controls are categorized by what their effects inhibit. Movement modifiers in some way inhibit the ability to move, while action modifiers in some way inhibit the ability to attack or cast abilities.

Movement Modifiers Action Modifiers
Airborne icon Airborne Airborne icon Airborne
Charm iconFlee iconTaunt icon Forced Action Charm iconFlee iconTaunt icon Forced Action
Grounded icon Ground Grounded icon Ground
Nearsight icon Nearsight Nearsight icon Nearsight
Sleep icon Sleep Sleep icon Sleep
Stun icon Stun Stun icon Stun
Suppression icon Suppression Suppression icon Suppression
Stun icon Suspension Stun icon Suspension
Knockdown icon Knockdown Blind icon Blind
Root icon Root Disarm icon Disarm
Slow icon Slow Silence icon Silence
Cripple icon Cripple

Increasing the duration of Crowd Control

Brittle icon Brittle is a status effect that can be applied by Ornn OriginalSquare Ornn's Bellows Breath Bellows Breath and Call of the Forge God Call of the Forge God.

Each mark reduces the target's Tenacity icon tenacity by 30%. The duration ofAirborne icon Airborne effects are also increased upon consumption of the mark.

Countering Crowd Control

Crowd Control immunity example

Ragnarok Ragnarok causes Olaf OriginalSquare Olaf to become immune to the Airborne icon knock up from Alistar OriginalSquare Alistar's Pulverize Pulverize.

Crowd control can be countered in various different ways.

Immunity

Units that are immune to crowd control will completely negate any attempt at its application on the recipient. This does not, however, necessarily mean the user is now also unaffected by crowd controls already applied (unless the ability had an innate Remove Scurvy cleanse effect). Immunities lasting for a short period of time will prompt that a particular unit "Can't Be Disabled!" or "Can't Be Slowed!" as well as "Spell Immune!" if crowd control is imposed.

Total Immunity

All crowd control debuffs currently in League of Legends can be prevented with Cc-immune icon total CC immunity:

  • Fiora OriginalSquare Fiora's Riposte Riposte provides immunity to all forms of CC applied during the parry.
  • Galio OriginalSquare Galio's Hero's Entrance Hero's Entrance provides immunity to all forms of CC during the dash and for a moment after the landing upon impact.
  • Kled OriginalSquare Kled's Dismounted Skaarl the Cowardly Lizard Dismount provides immunity to all forms of CC applied during the dismount and Chaaaaaaaarge!!! Chaaaaaaaarge!!! provides immunity to all forms of CC applied in the duration.
  • Malzahar OriginalSquare Malzahar's Void Shift Void Shift provides immunity to all forms of CC while active.
Epic Monster in Stasis example

Bard OriginalSquare Bard's Tempered Fate Tempered Fate putting Baron NashorSquare Baron Nashor into Stasis icon stasis regardless of its immunity to Stun icon crowd control.

Slow Immunity

Slow Immunity example

Highlander Highlander causes Master Yi OriginalSquare Master Yi to become immune to the Slow icon slow from Kog'Maw OriginalSquare Kog'Maw's Void Ooze Void Ooze.

Main: Slow_resist#Slow_Immunity

EditSlow immunity is a status effect that prevents the application of Slow icon slows, and in some cases Cripple icon cripples too.

The following effects prevent the application of Slow icon slows and Cripple icon cripples:

The following effects only prevent the application of Slow icon slows:

Displacement Immunity

Unstoppable example

Unstoppable Force Unstoppable Force causes Malphite OriginalSquare Malphite to be unaffected by the Knockdown icon knockdown from Veigar OriginalSquare Veigar's Event Horizon Event Horizon.

Unstoppable icon Unstoppables provide immunity to Airborne icon displacements, (including Knockdown icon knockdown, Realm of Death Realm of Death and The Show Stopper The Show Stopper) Sleep icon sleep, and in some cases to Stasis icon stasis. The effects of other types of crowd control and Fate's Call Fate's Call are deferred until the unit is no longer unstoppable, where their remaining duration may still affect them.

Spell Shields

Main Article: Spell shield

Spell Shield example 2

Banshee's Veil item Banshee's Veil preventing Orianna OriginalSquare Orianna from being affected by Blitzcrank OriginalSquare Blitzcrank's Rocket Grab Rocket Grab.

While not specific to crowd control, Spell Shield spell shields can be considered to provide pseudo-CC immunity against a single spell, but this is not guaranteed - abilities that do not interact with spell shields (such as Karthus OriginalSquare Karthus' Wall of Pain Wall of Pain) will still apply any attached crowd controls if possible. Multiple active spell shields existing on the same unit simultaneously will break against a single hostile ability.

  • Nocturne OriginalSquare Nocturne's Shroud of Darkness Shroud of Darkness provides immunity to CC applied with first instance of ability blocked in the duration.
  • Sivir OriginalSquare Sivir's Spell Shield Spell Shield provides immunity to CC applied with first instance of ability blocked in the duration.
  • Banshee's Veil item Banshee's Veil provides immunity to CC applied with first instance of ability blocked while passive is ready.
  • Edge of Night item Edge of Night provides immunity to CC applied with first instance of ability blocked while passive is ready.

Removal

Crowd control removal example

Karma OriginalSquare Karma activating Mikael's Crucible item Mikael's Crucible on herself to remove a Stun icon crowd control debuff.

Most types of Stun icon crowd control can be Remove Scurvy removed after it has been applied, with the ability or item in question being still castable while affected by the CC it removes, even if that CC normally precludes ability or item usage. Mikael's Crucible item Mikael's Crucible is an exception of this, but the target may still be able to cleanse CC-s affecting him if the item was activated ~0.2 seconds before the CC was applied.

Stasis icon Stasis effects cannot be removed as it prevents the usage of abilities entirely, including cleansing effects. Persistent area of effect Grounded icon grounding can be cleansed but is not reliant as the area checks and applies the effect continuously. The Stun icon stun component of Airborne icon airborne effects can be removed by cleanse effects, but their move block cannot, unless it's being overridden by another move block (i.e another displacing effect, Dash dash or Flash blink).

Reduction

Tenacity icon Crowd control reduction reduces the duration of crowd control effects by a percentage equal to its value. Sources of CC duration reduction will stack multiplicatively or additively with each other, depending on the source of the reduction. The statistical term is referred to as Tenacity.

Nearsight icon Nearsight, Stasis icon stasis, Suppression icon suppression, Drowsy icon drowsy and Airborne icon airborne are not affected by crowd control reduction and will always apply for their full duration.

Potency Reduction

This effect is unique to Slow icon slows; potency reduction reduces the effectiveness, or percentage, of slowing effects.

Self-CC

The following effects are comparable to crowd control, except that the effect is caused voluntarily and affects the user rather than a target.

  • Self-Stun: A champion that Stun icon stuns itself is unable to control its movement, attack, or use abilities.

Cast Times and Channels

The casting (sometimes "charging") of an ability cannot be cancelled by the player or an enemy except by death. Forced actions (such as Taunt icon taunt) will have no effect for the duration of the cast, and using airborne effects to move the player will not affect the trajectory of the skill - which will start from the point of the cast, not from the player's current location. Summoner spells and most items can still be activated while casting.

The channeling of an ability, by contrast, can be cancelled by hard CC, and will also automatically cancel should the champion attempt to perform another action (such as movement, casting another ability or attacking) - there do exist exceptions to this rule, such as Sion OriginalSquare Sion's Soul Furnace Soul Furnace cast while channelling Decimating Smash Decimating Smash, but these are usually specific coding allowances and not standard behaviour. Summoner spells and most items can typically be activated mid-channel without disrupting it.

Channeling and casting animations are generally not considered forms of crowd control, however disruptive they may be. There do exist several notable exceptions, however:

  • Channeled Self-Pacify: These abilities cause the champion to lose access to cast their abilities and issue attack commands. The champion may still freely move and use other summoner spells during this time.
