A "debuff" is a term commonly used in video games and role-playing games to describe a negative effect applied to a character or enemy. These effects can reduce a character's abilities, such as lowering their attack power, defense, or speed. Debuffs can be caused by various actions, including spells, skills, or environmental factors, and they often last for a specific duration. Debuffs are important for strategic gameplay, as they can turn the tide of battle by weakening opponents or enhancing the effectiveness of a player's team. Players often need to manage debuffs carefully, using items or abilities to remove them or counteract their effects. Understanding debuffs is crucial for success in games that feature them, such as MMORPGs or turn-based strategy games.
