Lightning Magic is a branch of Elemental Magic that utilizes electricity, more specifically, lightning, as a form of offense and defense. Mages who possess the ability to utilize such Magic are able to generate these elements from their bodies, and manipulate them, even shaping their attacks as they wish. Users of Lightning Magic are also capable of utilizing lightning from a distance, such as from the ground near them, or down from the sky. Lightning attacks work by electrocuting the opponents to various degrees, and there are spells that are said to be capable of completely paralyzing enemies, due to the extremely high voltage of the electricity employed in their use. Because of the high amounts of light produced with its use, Lightning Magic can also be utilized to blind opponents, albeit for a short amount of time.
Similar to other types of Elemental Magic, Lightning Magic can allow the user to transform their body into the element they control: by transforming into a lightning bolt, the user is able to avoid physical attacks, and have the added advantage of traveling around at very high speeds and damaging everyone or everything they come in contact with, much like real lightning. This Elemental Magic is very versatile and can also be imbued into Lacrima, as seen with Laxus Dreyar's Thunder Palace spell.
According to Laxus, each Mage that uses Lightning Magic has a specific signature, much like a fingerprint. Each Lightning mage can tell if the electricity belongs to their magic.
