In role-playing games, a status effect is a temporary modification to a game character’s original set of stats that usually comes into play when special powers and abilities (such as spells) are used, often during combat. It appears in numerous computer and video games of many genres, most commonly in role-playing video games. The term status effect can be applied both to changes that provide a character an advantage (increased attributes, defensive barriers, regeneration), and those that hinder the character (decreased attributes, incapacitation, degeneration). Especially in MMORPGs, beneficial effects are referred to as buffs, and hindering effects are called debuffs.
This matter varies as widely as the effects themselves and the games in which they appear. Some status effects go away on their own after a certain amount of time has elapsed. Most games contain items capable of healing status effects. Often these items heal a specific status effect, though many games also include one or more universal status effect removing items. Many games also include magic spells that can eliminate status effects. Most of the time status effects are removed at the end of a battle, however in some cases they continue to persist until either they are cured or until the character rests. Games with classes most likely will include a class capable of healing, which by default will have a chance to remove negative effects.

Pharmacology (from Greek φάρμακον, pharmakon, "poison" in classic Greek; "drug" in modern Greek; and -λογία, -logia "study of", "knowledge of") is the branch of medicine and biology concerned with the study of drug action, where a drug can be broadly defined as any man-made, natural, or endogenous (within the body) molecule which exerts a biochemical and/or physiological effect on the cell, tissue, organ, or organism. More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals.
