Flash is a blink summoner spell that activates instantly upon being cast, teleporting the player's champion a short distance in the direction of their cursor.

Strategy

Flash Flash can easily be used to escape from or catch up with a foe. It can be used to dodge or land abilities.

It can also be used to move over walls, either for a quick escape or in response to an opponent's dash.

You may sometimes want to save your Flash in favour of something else, because this summoner spell by default has a 5 minute cooldown.

Trivia

  • For a time, the inclusion of Flash Flash in the game was hotly debated and Riot Games Inc. even considered removing it from the game entirely, with parts of the community for and against removal. As a result, it has suffered several nerfs.
  • One of the pieces of trivia in the loading screen states that it takes 3 hours and 20 minutes (40 Flash uses) to travel from one fountain to another only with Flash Flash.
    • However, you actually need 49 Flash to go from one fountain to another, which would take 4 hours and 5 minutes.
