Limbo Magic: A Caster-type forbidden Lost Magic which allows the user to interface with the invisible world known as Limbo (輪墓, Rinbo, Literally meaning: Wheel Grave). Limbo is the realm between Earth Land and Edolas, and is stained with the essence of every creature and their counterpart from the opposite world. Limbo Magic lets the user access that essence, and can even make it possible to bring it to their world in some form. Limbo Magic uses the eyes, and is distinguishable by one or both eyes turning grey in color with ripple patterns surrounding the pupil. When Sasuke uses Limbo Magic, his left Sharingan is overtaken and morphed into a combination of the two eyes. It retains the features of the Limbo Eye, and gains the tomoe of the Sharingan on each ripple.
Susanoo - Susanoo is a gigantic, humanoid being made of the ambient Ethernano of Limbo that surrounds the user. When activated, Susanoo forms around the user and becomes an extension of their will, acting and attacking on their behalf. By default, Susanoo is anchored to its user and they to it: in its less developed forms it will move around with the user; in its more completed forms the user will be suspended within Susanoo, being brought with it as it moves around. This connection allows Susanoo to shield against physical attacks, one that becomes more difficult to penetrate as it is manifested more fully. If it is damaged, Susanoo does not regenerate and it can only be repaired either by advancing it to the next developmental stage or by dispersing it and then forming it anew. Although Susanoo is quite effective as a defense, it is able to distinguish in what it blocks. For example, the user can still perform spells while within Susanoo and the attacks will pass through it without complications. Others can be brought within Susanoo with the user's permission, and users can likewise choose to leave Susanoo's protective envelope. The latter property can be used against the user, as if an opponent can bypass Susanoo, however slightly and latch onto them, they can be pulled out of Susanoo. Susanoo is also only able to defend against physical attacks, so they are still vulnerable to things like visual or auditory attacks.
Susanoo has several developmental stages. Practiced users go through all the stages every time they manifest it, layering more advanced stages over earlier ones or stripping them away as is needed; they can choose to stop at any developmental stage along the way if they choose to. At its simplest level, users only manifest aspects of Susanoo's skeletal structure, such as a rib cage for basic defense or an arm for interacting with the surroundings. Once a full skeleton is made, musculature and, later, skin forms until finally a complete humanoid is shaped. In these early stages, typically only the upper half of Susanoo is materialized, with legs becoming common once it reaches its full humanoid form; however, not all Susanoo users can accomplish the latter feat. In its next stage, armor forms around the humanoid for further protection, causing it to resemble a yamabushi. In its final stage, users stabilize the Ethernano that comprises Susanoo to create a colossal form known as the Complete Body — Susanoo (完成体 須佐能乎, Kanseitai — Susanoo). In this state, Susanoo gains a tengu-like nose, wings for flight, and is clad with robes and ornate armor. Users can also channel their own techniques into the Complete Body - Susanoo.
Devil Slayer Magic (滅悪魔法 Metsuaku Mahō): Not much is known about this form of Magic except that it allows its users to use a specific element to slay Demons. It also lets the user eat their respective element to replenish strength and become immune to its effects like other types of Slayers. It has also been suggested that Devil Slayer Magic is a very fickle Magic, and that learning it too quickly and making use of its properties in rapid succession have adverse effects on the user, causing them to become afflicted with black markings that spread across their entire body. The users who master this Magic are able to summon these markings at will, allowing them to become immune (to a limited degree) to the effects of Curses, including the "Ultimate Curse" Memento Mori, which is supposed to completely annihilate whatever it touches. This Magic also allows its users to obtain information about a Demon by just observing it for a second.
Fire Devil Slayer Magic - This Devil Slayer Magic allows the user to produce the element of fire for various purposes. Like other Slayers, the user is able to consume external sources of fire, even ones formed from nothing, in order to replenish their strength and enhance their power, as well as having a tremendous resistance to the element of fire. Additionally, the user is able to somewhat control the flames of others and is able to just as easily burn a large scape of land with a mere flick of their wrist. Unlike other Slayer Magics, this Magic allows its user to obtain a basic analysis of a Demon's bodily composition based on sight alone.
Fire Devil's Rage - The Devil Slayer's equivalent to the Dragon Slayer's Roar and God Slayer's Bellow spells. The user, after inhaling, releases a large purple torrent of fire from their mouth, directing it towards an area of their choosing. The flames inflicts great damage upon those it contacts, causing everyone unable to resist it to be sent flying away with great force, as well as leaving behind a trail of destruction in its wake, heavily damaging the area it passes through.
Flame Wrapping Fire - The manipulated flames of Fire Devil Slayer Magic are used to cover the ribs of Susanoo, surrounding the user with a shield of black fire. In addition to the damage it can inflict, this technique has the psychological effect of causing melee enemies to hesitate in attacking the user of this technique.
Lightning Magic (雷系各種魔法 Kaminari Kei Kakushu Mahō): 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.
One Thousand Birds (千鳥, Chidori) - To perform, the user first gathers lightning to their hand; the high concentration of electricity produces a sound reminiscent of many birds chirping, hence the name. The strength of this lightning has been shown on occasions to damage the user's hand, peeling the skin and causing it to smolder slightly, but this does not appear to actually be debilitating. Once the lightning is gathered, users charge at their target and thrust the Chidori into them, piercing them and typically causing fatal damage. Despite the sound it makes, the rapid speed at which it's used makes it useful for assassinations. The speed at which the Chidori is performed, despite being one of its greatest assets, also represents one of its biggest drawbacks: users move at their target so fast that its causes a tunnel vision-like effect for them. Because they charge in a straight line it is easy for opponents to attack them, and because of the tunnel vision it is difficult for the user to see these attacks, much less react to them. For this reason, most Mages cannot use the Chidori safely. If the user has a Sharingan, however, these drawbacks are overcome: the Sharingan's heightened visual perception prevents the tunnel vision from occurring and its predictive capabilities make it easy for the user to avoid counterattacks. When imbued with Limbo Magic, Sasuke's Chidori turns black/grey, and can be used to damage and potentially kill a Dragon, whose body is otherwise impervious to standard spells.
Six Paths (六道, Rikudou): Six Paths is a Caster-Type Lost Magic, which allows its users to control each path every human belongs to. As a result, the user is granted overwhelming power and a wide range of abilities to fight with.
Deva Path (天道, Tendou) - Grants the user the ability to manipulate attractive and repulsive forces with objects and people.
Banshou Ten'in (万象天引, Heavenly Attraction of All Creation) - Banshou Ten'in is a technique that manipulates attractive force (引力, inryoku) to pull matter towards the user at will. It is possible to attract multiple targets at once, causing them to collide with each other.
Shinra Tensei (神羅天征, Heavenly Subjugation of the Omnipresent God) - Shinra Tensei is the Deva Path's ability to manipulate repulsive force (斥力, sekiryoku) at the user's will to push matter or techniques away. Depending on the amount of power the user puts into this technique, its strength and area of effect can be greatly increased. By using this technique as a defensive measure, all attacks directed at the user will be deflected, spiritual or physical, no matter the size, nature, power or mass, it can easily shatter wood, bones, metal, or stone walls. It was also seen capable of repelling flames caught on the user's body. Shinra Tensei can be used on a larger scale for massive destruction. A massive amount of repulsive force is placed above the target, crushing everything beneath in an enormous explosion.
Chibaku Tensei (地爆天星, Heavenly Body Bursting from the Earth) - The user releases a black sphere from his hands which acts as a center of gravity, drawing in everything in its surroundings to create an enormous satellite. He can also simultaneously release several black spheres and then subsequently drop the satellites on targets below.
Preta Path (餓鬼道, Gakidou) - Grants the user the ability to absorb magical energy in any form using the Blocking Technique Absorption Seal.
Fuujutsu Kyuuin (封術吸印, Technique Absorption) This ability was primarily defensive in nature as it is capable of absorbing magic, thereby nullifying its effect. This technique can also take the form of a barrier around the user's entire body, allowing them to absorb attacks from all directions. In addition to this, the Preta Path is able to absorb energy from an individual through physical contact.
Sharingan (写輪眼, Copy Wheel Eye): A powerful Eye Magic among the Uchiha clan that appears selectively among its members. It is regarded as one of the Three Great Eye Techniques (三大瞳術, San Daidōjutsu). The Sharingan grants the wielder two broad abilities: the "Eye of Insight" (洞察眼, Dōsatsugan) and the "Eye of Hypnotism" (催眠眼, Saimingan).
Eye of Insight (洞察眼, Dōsatsugan) - The user can see Magic energy, giving it color in order to distinguish it by its composition and source. It can see through some (but not all) obstructions and detect irregularities in a person's flow of Magic Power. The user is granted incredible clarity of perception, enabling them to read lips or mimic something like pencil movements. Sasuke's Sharingan is even able to see on a cellular level. In combat, this allows them to see fast-moving objects and, once fully developed, offers some amount of predictive capabilities: they can anticipate an opponent's next move based on the slightest muscle tension in their body and act accordingly to dodge or intercept. Although a Sharingan user can see these things, they also need the physical ability to actually act on the visual information. The user is able to copy almost any basic Magic they see, memorizing it with near-perfect accuracy. They can then either perform that spell or modify it to suit their needs. Again, Sharingan users need the prerequisite abilities before they can mimic a spell they have seen, and for that reason they cannot, for example, reproduce abilities they do not have or the lack the ability to perform without meeting certain conditions.
Eye of Hypnotism (催眠眼, Saimingan) - The user can perform what is generically called Genjutsu: Sharingan. While there are various manifestations and purposes of the ability, the better known one is to, through eye contact, suggest thoughts and actions to a target, coercing them to divulge information or act in a particular way, potentially without the target's awareness. In extreme cases, the Sharingan user can take complete control of a weaker target's body, forcing them to do exactly as the controller wishes; this control is visually indicated by the Sharingan's design appearing in the target's eye. The Uchiha are particularly infamous for using this ability on great Demons, and in fact can enter its or another Devil Slayer's subconscious to more precisely control the beast's power. Multiple targets can be taken control of in this way, though the more divided the user's attention is, the easier it is for targets to escape this control. While not an ability per se, the Sharingan user can appear as if they are able to "see the future". First, the user must perfectly mimic every move their opponent makes and possibly their thoughts and words through careful observation. Then, they suggest an action to the opponent such as a technique that the opponent and Sharingan user already know and copy that. With these things done, the user can complete the action even before the opponent does, possibly using the Sharingan's genjutsu to confuse or delay them.
