Debuff

A term used in massively multiplayer online role-playing games (MMORPGs) to describe a negative status effect, usually placed on a enemy by casting a spell. Debuffs may decrease the targets movement rate, attributes (stats), attack speed, luck, hit points (HP), magic points (MP), or decrease the regeneration of either HPs or MPs. Targets may also be blinded or silenced.
