Control the units, control the game.
In League of Legends, hundreds of abilities can affect other units with crowd control effects, also known as CC. Crowd control effects will reduce the amount of control that the targeted unit will have on its ability to move, attack, cast spells, or reduce items, to varying degrees.
With hundreds of crowd control abilities spread across the massive roster of champions, it can be a lot to keep up with or a lot to learn if you’re a new player. That’s why learning the categories and types of crowd control effects is important.
