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.


Flash.png 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.


  • The cooldown of this spell can be reduced by Insight and the Distortion item.png Distortion boots enchantment to 255 seconds, and by Ionian Boots of Lucidity to 270 seconds. Combining either the mastery or enchantment with the boots will provide a cooldown of 225 seconds. Combining the mastery and enchantment will result in a cooldown of 210 seconds. When all three are combined, Flash.png Flash has a cooldown of 180 seconds.
  • Flash.png Flash cannot be activated if the player is affected by hard crowd control.
  • Flash.png Flash and Teleport.png Teleport cannot be cast while silenced. This does not hold true for other summoner spells.
  • If cast while in possession of Distortion item.png Distortion boots, it grants a 20% movement speed buff for one second.


  • For a time, the inclusion of Flash.png Flash in the game was hotly debated and Riot 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) to travel from one fountain to another only with Flash.png Flash and without masteries.
