A Mejora (buff) is any status effect given to a champion or minion that gives it a beneficial performance boost. The opposite is called a debuff. Upgrades can benefit almost any character's attributes, such as health, mana, attack damage, and ability power, but in some cases they can provide more than a mere stat change. Most of the best are temporary, but some can last indefinitely (such as In the sights of
Tristana, which grants a permanent range increase for attack distance and abilities). Many, but not all, are lost upon death.
Some upgrades can stack a specified number of times, but most don't stack on their own. This means that repeated applications of the buff on the same target will not grant any increased effect and will only cause the duration of the buff to reset.
Certain abilities that have a unique cooldown before they can be used on the same enemy twice such as Blade to the Wind of
Yasuo and
Bear position
Udyr are not considered buffs applied to an enemy.
There are several sources of improvements in League of Legends; specifically, abilities, epic monsters, specific field upgrades, items, relics, speed altars, and summoner spell.
