Magic

Magic (魔術 Majutsu) refers to the manipulation of mana stored in the body to generate supernatural effects known as Magic Spells.

Mana
Magic requires an energy source in order to produce its effect in the corporeal world. Mana (魔力 Maryoku, lit. "Magical Power") is the natural energy source for employing and invocation of magic.

All living beings existing in the Six-Faced World innately have mana in their body. Souls normally dissipate into mana after death and can get reincorporated into the environment. The only known exception to this is people from outside the Six-Faced World that have been summoned. Summoned people are incapable of holding mana inside their body, thus incapable of using magic.

Mana or magical power reserve of a person is generally believed to be inherited and the amount one has is determined at birth. Due to the existence of individuals with the Laplace Factor (such as Rudeus, Sylphy) having enormous amounts of aggregate mana that increased since their birth, they were considered to be the only exception. This is later proved to be incorrect and not linked to the Laplace Factor. All people are capable of increasing their aggregate mana amount by stimulating their mana from a young age (seen in Julie). The ability to learn silent spell-casting is also linked to young age.

History
Long before the Great Human-Demon War, the world was engulfed in an unceasing spiral of battle and chaos. During that time, in order to fight their enemies the High Elves race entreated with the spirits of the forests to control natural inorganic elements like the wind and the earth. In this manner, the first magic spells were born. Modern form of magic took its form from humans imitating the spells used by the High Elves in battle and reworking them to convenience. Magic was mostly used only in battle and fending off obstacles. As a result, a large portion of the spells that came to exist are combat spells.

Incantations
In this method, one recites a set of words to cast a spell. Incantation acts as an activation trigger for spells, where uttering the words would create the effect without having to focus on the Mana coursing through one's body. As such, incantations are much less flexible than silent spell-casting due to a restricted amount of control one has while tuning the magic.

Incantations are the common method for casting spells as it is relatively easy to use. A magician typically uses incantations from when they were a beginner all the way to when they became a master.

Magic Circles
Invented by Demon Empress Kirisis Calisis, this method involves one inscribing patterns using a specialized ink or carved patterns to cast a spell. Magic circles cast the inscribed spell at a predetermined power whenever mana is poured into it. Because of this, magic circles have the least flexibility of all spell-casting methods, albeit being the easiest and fastest to use.

Earlier, magic circles were widely used until one magician succeeded at greatly shortening incantations. But for the more complex rituals involved in Summoning magic, where greater efficiency wasn't attainable, magic circles remained the primary means.

Melded Magic
Melded Magic or Combined Magic is magic where the caster uses consecutive spells to alter or enhance the effects of a single spell. Spells such as Dry Steaming (Wind and Fire) and Frost Nova (Wind and Water/Ice) are examples of melded magic. Melded magic is exclusive to attack magic; these are familiar and easy to piece together with basic knowledge of science.

Truncated Spell-casting
Truncated or shortened incantations are very similar to conventional spell-casting; the caster recites a predetermined set of words corresponding the magic they are using. With shortened incantations, as used by Roxy and Rudeus, cast times and flexibility are drastically improved over conventional casting. The casting of melded magic also becomes much easier due to the reduced downtime between incantations.

Silent Spell-casting
Silent spell-casting or Incantation-less spell-casting involves the caster manipulating mana itself in order to produce the desired effect. This method, unlike incantation and magic circles, does not require preparation for invocation as the caster only needs strong imaginative power to mold mana to their will.

It follows a process the caster calculates in their mind: First, the caster calls forth the shape of the spell they wish to use. Next, there is a window of time where they can add additional magical power to impact its size. Third, the velocity of the spell with which it will travel is adjusted. Finally, the caster releases the finished spell from their hand.

Silent spell-casting is a particularly unorthodox method of performing magic for almost no mages are able to completely skip the incantation. Since the process is convoluted and relies heavily on the caster's understanding of the spell, this method of spell-casting is not formally taught anywhere. Though even the most accomplished mages are not capable of this feat, it has been conjectured that this method can be taught during childhood as young minds are more flexible to pre-determined concepts of magic.

Main Category:

 * Attack Magic

Attack magic is comprised of spells that manipulate mana into tangible elements. The power, speed, effective range, and area of these spells are dependent on the amount of mana poured into them.

It is divided into four schools: Fire: Generate fire/heat Water: Generates water and in extension, ice and steam (melded with fire magic) Wind: Manipulates gases Earth: Generates earth, Manipulates earth and minerals

Healing magic mainly comprises of spells used for healing injuries and removing toxins.
 * Healing Magic

It is further divided into four schools: Healing: Magic for healing injuries Detoxification: Magic for purging poisons and disease Divine Strike: Magic used against incorporeal monsters and demons Protection: Magic for increasing one's defenses and create barriers (distorts mana in a finite space. Effects include nullifying magic activation and altering magic regeneration rate)

Summoning magic is used to call forth powerful beings to carry out the summoners's bidding.
 * Summoning Magic

It has two types of summons: Fiends: A class of beast that have intellect Spirits: An intelligent being called forth to reside in an artificial body, has been stated by Rudeus to be much akin to Mana Programming.

Magic Rank Title

 * Spell rankings are typically proportionate to the amount of mana necessary to cast the spell. There are exceptions however, such as with Badigadi and Orsted, Rudeus's magic is considered to be of a higher rank despite using lower ranked magic as the base.


 * It has been stated that only 1 in 20 people is born with the capacity of using mana and of those, only 1 in 20 is capable of learning how to master it and becoming a mage. However, only 1 in a 100 of those is actually capable of becoming an advanced magician in only 1 element.


 * The magician's ranking title is determined by the most advanced spell s/he could cast.

Diseases
Since the Human-Demon Wars, there are also several magic related diseases that are known to exist and in time the denizens of the Human World became immune to it or a way to treat them has been discovered.

Magic Stone Disease

 * Magic Stone Disease is an extremely rare magical virus that turns that kills its host by gradually turning it to a purple magic stone starting from their feet and eventual death upon reaching half of their body at the very least.

Drain Syndrome

 * Drain Syndrome is a magical illness first found in Humans from the early ages into the Laplace Wars that affects a child born with out any magic capacity who absorbs magic externally and after accumulating it for 10 years, they will fall ill and die.

Trivia

 * The amount of magician capable of using shortened or silent spell-casting are very few since the method of learning it was previously unknown. Roxy, Rudeus, Sylphy and Moore are of the few capable before the method of nurturing silent spell-casting was popularized by Rudeus.
 * It is stated by Future Rudeus that "magic in this world is omnipotent. Once you realize that, you can essentially do anything."
 * Many attack magic functions by converting mana into physical substances. It appears that the materials manifested take a while to stabilize, evidenced by the fact that projectiles from attack magic can be disintegrated by using manatite stone, but figurines created by Rudeus aren't affected.
