A buff is a term used to describe the improvement of a character (or aspect of a character), either through updating a game or by releasing a sequel. Buffs are often done as an attempt to balance the roster, by strengthening characters that are too weak; however, buffs can also be inadvertently added if a character is indirectly strengthed by an external gameplay change. Buffs contrast with "nerfs", which involve the weakening of a character or aspects of a character between sequel games and game updates.
