Example
Cleanse in action

Cleanse is a 'non-targeted' summoner spell. Its primary function is to remove active crowd control effects, allowing the summoner to continue pursuit or escape.

Strategy Edit

  • Cleanse will provide 3 seconds of 65% crowd control reduction after activation (or 4 with Summoner's Resolve). This stacks multiplicatively with other sources, such as Tenacity and champion abilities.
    • This crowd control reduction will have no effect on additional Ignites, but will reduce the duration of Exhausts movement speed slow.
  • Cleanse has no effect on Suppression, knock-ups, knock-backs, grabs and flings. This is true for both the removal and reduction effects.

Trivia Edit

  • Previously the tool tip stated that Cleanse was able to remove the Sleep debuff, although no such effect existed in the game.
  • Cleanse was named Boost up until V0.9.22.15.
