Channel example

Karthus OriginalSquare Karthus Channeling icon channeling Requiem Requiem.

A Channeling icon channel is a trait of certain abilities which is Silence icon interrupted by Stun icon crowd control effects that inhibit casting. These effects are: Airborne icon airborne, Charm iconFlee iconTaunt icon forced action, Silence icon silence, Silence icon disrupt, Stasis icon stasis, Stun icon stun and Suppression icon suppression. When a caster activates a channeled ability, the caster stops performing any previous actions.

While the effects of the ability are present the caster is channeling the ability. In most cases, the caster can interrupt the channel by performing an action, such as moving, attacking, or casting an ability. Some channels cannot be canceled at all, which prevent the caster from performing any act. Channels that require the caster to be out-of-combat means that entering combat interrupts their channel.

The channeling status disables other effects specified by the ability from being used. This includes attacking, moving, casting abilities, and using summoner spells or item actives.

Unstoppable Channels

The following channeled abilities cannot be Silence icon interrupted by Stun icon crowd control and are only stopped by Death death. Note that any channel can be unstoppable as long as the user is Cc-immune icon crowd control immune in the process of doing so (e.g. Morgana OriginalSquare Morgana could place her Black Shield Black Shield on a channeling target and they would be considered unstoppable while the shield holds):

Champion Ability Channel duration Notes
Aurelion Sol OriginalSquare Aurelion Sol Voice of Light Voice of Light 0.3 seconds; classic channel (unstoppable) Channeling for the full duration is required to deal damage and knock back. Channel starts immediately after a 0.35 seconds cast time.
Irelia OriginalSquare Irelia Defiant Dance Defiant Dance 0-1.5 seconds; charged channel (unstoppable) Channeling grants physical damage reduction and increases the damage over the duration. Can be recast to end the channel early.
Pantheon OriginalSquare Pantheon Aegis Assault Aegis Assault / Aegis Assault 2 Empowered Aegis Assault 1.5 or 2.5 seconds; classic channel (unstoppable) Channeling deals damage every 0.125 seconds and renders him invulnerable in a certain condition. Can be recast after 0.3 seconds to end the channel early. Pantheon can move while channeling, but is slower when moving backwards.
Sion OriginalSquare Sion Unstoppable Onslaught Unstoppable Onslaught 8 seconds; movement channel (unstoppable) Channeling renders him immune to crowd control and increases the damage and stun and pull duration over the first 3 seconds of channeling. Can be recast to end the channel early and apply effects as if he collided.
Urgot OriginalSquare Urgot Fear Beyond Death 2 Mercy (recast of Fear Beyond Death Fear Beyond Death) 1.5 seconds; classic channel (unstoppable) Channeling launches chains which suppress, reel, and execute. Urgot can move while channeling.

Uniquely, Unstoppable Onslaught Unstoppable Onslaught's is a channeled ability which additionally grants him Cc-immune icon crowd control immunity during the channel, therefore it cannot be interrupted as any attempt at cast-inhibiting Stun icon crowd control will be negated.

There are a few exceptions, however:

  • The ability still be interrupted by death, as with all other channels. If so, the effect will end as if he collided with terrain or an enemy champion, dealing the damage and stunning and knocking up enemies around his current location immediately.
  • Due to a bug with Roar of the Slayer Roar of the Slayer, he can occasionally cast his ultimate despite being Root icon rooted. In this case, he will stand in place until the root's debuff duration ends. During this time, the damage, stun duration and movement speed granted by the ability will still ramp up, and enemies that come into contact with him will be affected by the collision normally.
    • The same bug allows him to cast his ultimate during crowd control that inhibits casting and movement abilities. If he starts charging the ability while Stun icon stunned, Airborne icon airborne or Silence icon silenced for example, the channel will be interrupted almost immediately, and he will perform the same leap as he does when the channel ends at maximum duration or is ended via its recast.
  • An allied trigger of the Blast ConeSquare Blast Cone's Airborne icon airborne effect is not considered hostile crowd control and will thus disregard his Cc-immune icon crowd control immunity, interrupting his ultimate in the process. He will turn to face the direction in which he would be knocked into, then initiate the leap as if he collided with an enemy champion or recasted the ability the ultimate or was affected by an enemy's hard crowd control, overriding the initial airborne effect of the plant.
  • If he is put into Stasis icon stasis by an allied Bard OriginalSquare Bard's Tempered Fate Tempered Fate (does not count as hostile crowd control in this case), he will attempt to leap forward (he can't while in stasis however) then initiate the area of effect as if he engaged in a collision. The ability does not appear to go on cooldown for a few seconds according to the HUD but trying to cast it does not bring any result. The steer and channel indicators do not disappear however and he is still able to perform actions as if he were not channeling.

Since Unstoppable Onslaught Unstoppable Onslaught is a channeled spell, Kalista OriginalSquare Kalista's Fate's Call Fate's Call will wait with its effect until the channel has ended, dragging him back to her across a potentially massive distance. The pull transpires immediately after the channel ends, but he will still leap forward despite not colliding with anything. The area of effect still occurs in the landing spot he would've stopped at.

Charged Abilities

A charged ability has two activations - the first begins the charging and the second will fire the ability. While using quick cast, the player must keep the hotkey held down to charge the ability and it will fire upon releasing the key. For most charged abilities, the caster is still able to move freely including the use of Flash Flash and Dark Passage Dark Passage.

Charging is a sub-classification. The forms of crowd control that will interrupt a charged ability depends on the ability's super-type.

Xerath OriginalSquare Xerath Arcanopulse Arcanopulse 0–3 seconds; classic channel Channeling increases the range over 1.5 seconds and gradually slows him. If the channel times out, the ability cancels and refunds half of its mana cost.

Casting Times

Most abilities have a very brief casting time that will interrupt other actions, such as movement or attacking (most will automatically have the champion continue in their previous actions, although some will interrupt previous actions indefinitely). These casting times cannot be interrupted by any other effect than the caster's death, unless it was protected by Revival icon resurrection. Casting times will display a channeling bar above the HUD.

The effects of Stun icon crowd control are ignored while casting, with the exception of Airborne icon displacement effects. Being displaced while casting a Sear direction-targeted ability will still fire the projectile from the point of cast regardless of the caster's position once the cast time has finished (although it's worth noting that the animation will occasionally fire from the new location for certain abilities of the targeting type). For Flash blinks and Dash dashes, they too will move toward the selected target after the casting has finished regardless of crowd control effects suffered during their cast times

These are notable examples of cast times that are much longer than usual, or casting times that are misunderstood as bugs on account of their ability to ignore crowd control:
