淨化

Template:Spell data 淨化

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[]

Cleanse will remove any and all of the following effects: Blinds, Charm, Fear (including Flee), Movement Slows, Polymorph, Silences, Snares (including Entangle, Roots and Immobilizes), Stuns and Taunts.
- Cleanse will not remove non-CC effects, such as: damage over time, attack speed reductions, defence shredding and grievous wound. Quicksilver Sash is an alternative to Cleanse that will remove all of these effects.

Cleanse will provide 3 seconds of 65% crowd control reduction after activation (or 4 with Summoner's Resolve 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 Exhaust's 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.

Cleanse will remove all effects contained within the crowd control debuff.
- For example, it will remove the following attack speed slows: Glacial Storm, Crippling Strike, Cripple, Wither, Ice Blast, Absolute Zero, Warden's Mail and Randuin's Omen.
- Tryndamere's Mocking Shout is an example of an ability where the two parts are separate debuffs. This is also true for Anivia's "Chill" debuff, applied by Flash Frost and Glacial Storm.
- Interestingly, Ground Slam and Barrel Roll are the only attack speed slows in the game not connected to a movement speed slow and so are the only attack speed slows that Cleanse will not remove.

Trivia[]

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.
