Buff refers to any improvement in effectiveness or desireability made to an existing element; such as Health, Damage, Range, or any number of other improvements. Players might references game elements being buffed in-game, via perks or other pickups, or being buffed in the meta via game patch changes.
Buff is a term used in some video games, especially MMORPGs and MUDs, to describe increases in the power of a game element. There are two main usages:
The first describes a permanent (or at least indefinite) increase in power levels as a result of adjustments to game mechanics, usually in pursuit of game balance. In this usage, buff is the opposite of nerf.
The second usage of buff describes an effect (usually cast as a spell) that temporarily enhances a player or target area.
