Definition of “Buff” in League of Legends?

A buff is a temporary effect that increases the strength of a champion, minion, or monster. Buffs can raise offensive stats such as AD (attack damage) or AP (ability power), boost survivability through shields or bonus defenses, or grant unique enhancements like movement speed, regeneration, or empowered abilities. Buffs are commonly gained from champion abilities, items, jungle monsters, or neutral objectives and typically last for a limited duration.

In gameplay, managing buffs is an important part of team strategy. Some buffs, such as those from jungle camps or objective control, provide significant advantages that can influence fights, Push pressure, or map control. The term buff is also used in patch notes to describe when a champion or item receives improvements to increase its effectiveness. The opposite of a buff is a nerf.
