Magic

"Magic" is an integral part of the world of "Arifureta". While only one form of magic have been showcased in the "Main Series" and "Zero", but during the "After Story" in the Web Novel, various other concepts of magic have been revealed.

"Tortus" Magic
Its unknown if "Magic" existed in Tortus from the beginning or not. But the current form of magic is derived from the magical technology and the "Ancient Magic", which originally originated in a different world, and was brought to Tortus by people who had escaped the destruction of the said different world. It is believed that the present form of magic is a degraded version of the original "Ancient Magic", which could control over the core elements that govern the laws of a world.

Elements, Levels & Aptitude
Like with Magic in general, it is divided into various basic Elements as follows; "Light", "Dark", "Earth", "Wind", "Fire", "Water", "Ice", "Thunder". Many type of Magic Spells fall under one of these Element categories, like both "Barrier" and "Healing" Magic Spells fall under the "Light Element".

Each Spell is graded a Level depending on their base power, strength and usage difficulty. The grades of Spell are as follows; "Beginner Level", "Intermediate Level" and "Advanced Level".

Aptitude with Magic or Spell can differ between people either because they were born with it, or because they belonged to a particular race. Aptitude with Magic can also help someone to either easily learn a Spell, or focus more power more easily into a Spell. In general, 'Humans' as a race have average aptitude towards Magic and Spell, while 'Demons' have a high aptitude towards it. It is said that the 'Vampire' race had the highest Aptitude towards Magic and Spell, while the 'Demi-Human/Beastman' had almost no aptitude towards Magic. 'Dragonman' being a race which is more close to a monster, has high aptitude towards Magic and Spell.

Mechanics
In order to be able to use this form of Magic, a person must first possess Mana in their body, and then channel their Mana to a Magic Circle (which has the Spell inscribed within it) with the help of an Incantation, and then cast a Spell. There is no limit as to what type or kind of a Spell a person can use.

An Incantation is a chant which helps channel the Mana of a person, and the length of an Incantation is directly proportional to how much Mana one could pour into a Magic Circle, so the effectiveness of a Spell was directly proportional to the amount of Mana used to cast.

As for the Magic Circle, the more complicated a Spell is or has a larger area of effect, it required more inscriptions which needed to be added to the Magic Circle, making it quite large in many cases. So, even a basic simple spell like "Fireball" might need an intricate Magic Circle which could span over 10cm in diameter, since the Magic Circle have to contain the inscriptions for the element, strength, range, span, mana required and maintain duration. Magic Circle are generally of two different types. The most common method is to inscribed it onto a special kind of disposable paper, which while allows for many different variations of Spell usage, but has the limit of one time only. The other method is to carve the inscription for the Magic Circle on various kind of specific minerals, which while bulky and limited in Spells they can cast, but they are reusable and are far more powerful in general.

However, all the requirements of casting a Spell can be ignored depending on the Skills of Magical Affinities a person possess. Magical Affinity allowed a person to apply various effects depending on their affinity to the Spell without it losing either power or strength. Like, if a person possess an Elemental Affinity, they can ignore the need to add the inscription of the element into the Magic Circle, thus shortening its size. Instead they have to imagine the form of the element while chanting the Spell, and are able to add the element into the Spell in that way. Possessing Magical Affinity to an element also increases the base strength and power of a Spell, depending on the additional Skills or Derivative Skills a person might possess. Some affinities might also increase the efficiency of usage, decease the Mana consumption and can also affect the cast time of a Spell. As most people who possess Mana have some form of Magical Affinity, so in general people can cast a Spell with a Magic Circle of less the 10cm in diameter.

Though for a person with no Magical Affinity Skill whatsoever, even a basic simple spell like "Fireball" would need a Magic Circle of over two meters in diameter, because of additional additions of inscriptions needed to make up for the lack of Magical Affinity, thus making the spell practically useless.

But Skills like "Mana Manipulation" or "Image Composition" can remove the requirement of needing an Incantation or Magic Circle completely; as "Mana Manipulation" allows a person to directly manipulate their own Mana thus removing the need for the Incantation, while "Image Composition" allows the user to create an imaginary Magic Circle in their mind, in place of a physical one, thus removing the need for either a Spell paper or magical equipment.

"After Story" - "World of Nature" Magic
The existence of magic is mostly related to nature and the energy that inhabits living things called Blessing Power. The technique that allows the humans of this world to manipulate the power of nature and blessing power is called Blessing Arts.

Mechanics
This world relies on the power of life energy generated by nature called Blessing Power which is present in all nature and living beings such as animals and humans. The only exception to this is the "Dark Beings", who exist as a parasitic species which feeds upon Blessing Power. Blessing Power aids in development of this world’s plants so if a area is overflowing in Blessing Power, it's flora would grow and develop in a very fast rate. Conversely, if a area was lacking in Blessing Power the growth of flora would slow down and if the Blessing Power was completely removed from a area, it would turn into a desert wasteland.

With the life energy of the planet flowing through nature, the inhabitants there possess a degree of nature worship. Though they worship the nature goddess called Foltina, who is thought of as the mother of all nature and a living manifestation of the Blessing Power that inhabits nature and of the flora that dwells in the world.

Blessing Power can be harnessed by humans to be used as a way of aiding them in either development or combat. The method of allowing humans to harness Blessing Power is called Blessing Art. Blessing Art allows humans to invoke various natural phenomena by offering their prayers to nature and '''Foltina. '''

According to Kouki Amanogawa, while the energy properties of the Blessing Power that is invoked by Blessing Art is different from the magic that is utilized on Tortus, the operation procedures for Blessing Art and Tortus Magic is similar.

Blessing Art can be used to invoke various natural phenomena such as elemental forces like fire, water, earth, wind, sunlight but it can also be used in various other ways such a body strengthening or healing.

Blessing Art can be invoked by any human, the talent of a individual would determine if they would be skilled enough to invoke Blessing Arts in combat. Similar to Tortus Magic, a individual can have a greater affinity for invoking a certain elemental force.

While normal Blessing Art can be invoked by any human, there exists a special Blessing Art called Heaven's Blessing Art which is exclusive power of the royalty of Synclea Kingdom. Each royal person has one unique Heaven's Blessing Art which is extremely powerful. However as a consequence of it's power, Heaven's Blessing Art is very taxing for the user to invoke, draining stamina at a great rate when continuously invoked, which can lead to it's user getting weak and suffering aftereffects that will be permanent, in some cases causing death if the user continuously uses Heaven's Blessing Art while already reaching their limit.

"After Story" - "World of Sky" Magic
The existence of magic was minimal in this world. It primarily dwelled in the dragons that inhabited it, and in a special blue ore known as "Sky Core". A special race of dragons, called Monarch Dragon, were especially proficient in using certain magical abilities.

Mechanics
This world maintained a balance of positive and negative energy. The dragons and sky core take in negative energy, then turn that energy into positive energy that they release back. After the released energy accomplished its objective, it would turn back into negative energy, then that energy would be taken in by dragons and sky core once more. If either substance is severely depleted, the world would be overrun by negative energy that can cause a huge impact on the planet in the form of rain that would kill anything it touches.

Sky Core posses unique traits where it can be changed into various kinetic energy, stimulate the growth of crops, and neutralize gravity. Unfortunalty, the process to extract it was very difficult and it required a sufficient amount in order for it to be of use. It was later discovered that the cores of a dragon could accomplish that same feats at a fraction of the size of sky core.
