Can Summoner Spells Be Cast While Under A Suppressor?

In League of Legends, summoner spells are a unique feature that can be used in various situations. Suppression is the only CC condition that prevents the use of summoner spells, but silence, knockup, stun, snare, etc. can be used while under the effects of Silence icon cast-inhibiting crowd control. Items like Quicksilver Sash can still be used, so summoner spells are safe to use while being stunned.

Suppression acts as a normal stun and locks all summoner spells, such as flash and cleanse. The only two spells you cannot use/channel while CC’d (silence, stun, snare, etc.) are Flash and Teleport. To get out of suppression, either the caster gets interrupted or you use the active on Quicksilver Sash.

Silence effects, which prohibit champion abilities and summoner spells but do not inhibit control of your champion (allowing auto-attack only), are less common. However, Suppression is the only CC condition that prevents you from using any summoners whatsoever. Cleanse does work to get rid of silence, removes all stuns, slows, taunts, fears, snares, silences, blinds, and immobilizers.
