Metamagic is a special term used by erudite and educated wizards to describe a single class of spells and magical items—those powers that alter or affect other magical spells and items. Met a magic spells do not directly affect people, objects, or events. Instead, the powers of metamagic are used to alter the fabric of spells themselves. Through metamagic spells, such as far reaching or squaring the circle, the once inviolable limits of a spell can be altered. Range, duration, casting time, area of effect, and even sound and color can be tailored through the use of metamagical spells.
Although the concept of metamagic has existed since the beginning of magical study, it has generally been ignored by most wizards, who have been far more interested in spectacular effects and immediate results. However, a few independent researchers have continued to explore and expand this esoteric field of study.
