A buff is any status effect given to a champion or a minion that gives them a beneficial boost to their performance. The opposite is called a debuff. Buffs can benefit almost any attribute of a character, such as health, mana, attack damage, and ability power, but may provide more than mere statistical changes in some cases. Most buffs are temporary, but some may be permanent (such as permanently granting a range increase for her attacks and abilities). Most, but not all, are lost upon death. A buff given to Champion B by Champion A, such as , will apply Champion B's magic penetration, spell vamp, damage modifiers, , etc...

and are not considered to be buffs applied to an enemy.There are several sources for buffs in League of Legends; specifically, abilities, epic monsters, field-specific buffs, items, relics, speed shrines and summoner spells.
