Starting with League of Legends patch 25.15, champion-select in all draft modes and ARAM will introduce ability previews. This feature provides an efficient way to stay updated with the game's vast champion roster without requiring you to exit the client.

To engage this feature, simply position your cursor over the champion's portrait for a few seconds to conveniently preview the play style of that particular champion.

However, if you possess a thorough familiarity with your champions and find this feature unnecessary, you can disable it through the in-game settings.
