Slow

A slow is a soft form of crowd control that reduces a champion's movement speed by a percentage for a short time. It does not stop a target outright, but it makes them far easier to chase down or escape from.

Slows are the most common CC in the game and are often attached to a champion's basic abilities or items. Stacking several slows, or pairing one with a root, can keep an enemy in range almost as effectively as a hard stun. They are the bread-and-butter tool for kiting melee threats and for securing kills on fleeing opponents.
