Recall

Recall is an ability that every summoner has, regardless of champion chosen. The spell allows a champion to hard channel for 8 seconds (or seconds in Dominion) and teleport back to the respawn pool after the channel is completed (provided the channel is not interrupted).

Development history
The Recall function was originally tied to, which was a purchasable item that could be activated to return to base. The function was then made into an optional summoner spell, and eventually into a feature inherent in all champions.

Gameplay
Recall is activated either by clicking the Recall button on the ability panel or by pressing the key to which the function is bound ("B" by default). After activating Recall, the champion will enter a hard channel state for 8 seconds. The channel will cancel if the champion is hit by any attack or spell, by moving, or performing most actions. If the channel is successfully completed, the champion will be teleported to his or her respective team's respawn point.

Strategy
While beginning to fade away to stealth, you can begin casting Recall or Improved Recall. This does not work with instant stealth spells, such as  or.

Enhanced Recall
When Dominion was released, Recall was remade to fit in to the game mode's fast-paced style, creating Enhanced Recall which takes seconds to channel.

Improved Recall
In Season Two, the Utility mastery tree included a tier 1 mastery to reduce the cast time of Recall by 1 second and Enhanced Recall by  seconds.

Recall Animation
Since V1.0.0.140 patch, new champions and certain skins, like legendary skins (e.g. ), have received a special recall animation and a few have received special quotes. Also, when an older champion gets a visual upgrade, all of his or her skins are outfitted with a new recall animation. Below is a list of champions and skins released that currently have recall animations:

Player disconnection
When a player leaves the game his or her champion will automatically attempt to walk back to base. Soon after arriving at the base, the champion gains a huge bonus to magic resistance and armor; this is to prevent enemies from using global abilities (like and ) to instantly kill champions that have disconnected early in the game. Players who have disconnected prior to the game starting are granted the same bonus Magic Resistance/Armor.

Trivia

 * The old is possibly a reference to the film The Matrix. In the film Neo is offered the chance to take a red or a blue pill, signifying his choice of whether to continue living in the world he knows or to wake up.
 * It was previously possible for champions with abilities that make them dash to an enemy champion to follow an enemy that has just finished recalling and teleported to base, making the champion fly all the way to the enemy base.
 * Projectiles will still do so.
 * If you recall while the Nexus is destroyed, the camera will attempt to center on your champion rather than the exploding Nexus.
 * When he was first remade, an oversight allowed to be able to use Recall to trigger his  passive, so he could refresh the cooldowns of all of his abilities by simply rapidly pressing the recall key.
