A spell is any action in League of Legends that directly affects gameplay, whether it comes from a champion’s abilities, items, runes, or other interactive effects. Basic abilities, empowered Auto attacks, summoner spells, and item actives all fall under the category of spells, and activating one is referred to as casting. Because spells define how a champion functions, understanding their cooldowns, targeting types, and resource costs is essential for both trading and Teamfights.

In everyday usage, players often refer to summoner spells specifically when they mention “spells.” Common examples include Flash, Ignite, and Exhaust, which can change the outcome of skirmishes or provide critical Utility during engages and escapes. Knowing the status of enemy summoner spells helps players plan ganks, pressure lanes, and coordinate plays around major objectives. Since every champion relies on spells in some form, mastery of spell usage and timing is one of the core skills that separates experienced players from beginners.
