Night Dragon Slayer Magic

Shadow Dragon Slayer Magic (影の滅竜魔法 Kage no Metsuryū Mahō) is a Caster Magic, Lost Magic and a type of Dragon Slayer Magic, that utilizes the element of shadows.

Description
Shadow Dragon Slayer Magic is a sub-type of Ancient Dragon Slayer Magic, which can be utilized only by Dragon Slayers. This magic allows its user to transform their physical bodies into a Dragon's, granting them various characteristics, that are typical for a Shadow Dragon. The user is capable of freely creating and manipulating shadows, or even turning their body into a shadow, that can't be touched by normal means. With this Magic, or rather with the ability of taking the shadow form, the user is also able to move swiftly, dodging efficiently and making surprise attacks. However, this shadow form doesn't give them invincible from, as the user can be vulnerable to attack, if theu face another user of shadow form, or is caught, when they were in tangible form. But, as it was shown by Gajeel Redfox in his battle with Rogue Cheney, the opponent needs great reflexes and feeling of time to take advantage and transform the attack of Shadow Dragon Slayer into the opening for coutner attack.

Shadow Dragon Slayer Magic allows its users to create and control shadows from any part of their body, which can be used both in melee combat for an offense and a defense. It is known, that while shadow form gives its user the intangibility, a Light or White Dragon Slayer Magic user can deal the damage for Shadow Dragon Slayers, but it is unknown, if Solar Dragon Slayers can reach such benefit. Being a form of Dragon Slayer Magic, this Magic allows its user to consume external sources of shadows to restore their body's health and regain strength. Also, the Shadow Dragon Slayer is immune to shadow element. Howerer, the user, like all Dragon Slayers, can not consume their own produced element. But, Shadow Dragon Slayer, when they are mastered their Magic, can reach some unique advantage, when they become more powerful in places with great darkness or even great light. As a result, they can reach the peak of their power at night times, while the light can make the shadow stronger. It is unknown, but can be truth, that like all Dragon Slayers, Shadow Dragon Slayer can consume some shadow or darkness of "higher class", like God Slayer's shadows, and in order to consume such shadows, the user must do a self-nullyfying of their Magic Power, which will grant enough room to consume and even use such shadows. Finally, it must be said, that the shadows produced by Shadow Dragon Slayer are able to be utilized in several different ways, allowing for a high level of adaptability; the shadows are able to be released in freeform, as condensed, or even molded into the shape of a weapon, taking on the properties of said chosen shape.

While, there can be pure Shadow Dragon Slayers, also, there can be the enhanced one. As the phenomenom of Dual Modes and Dual Element Magic us progressing, a Shadow Dragon Slayer also can attain it. If he or she is somehow capable of successfully eating an opposite to shadows element, i.e. light or whiteness, they will enter White Shadow Dragon Mode, as it was seen with Future Rogue Cheney. In this form, the shadows and light will fuse together, and the user gains the ability to use both elements simultaneously. As result, the user's attacks will possess the properties and destructive ability of both elements i.e. shadow slicing and intangibilty with the piercing properties of light. After entering said Mode, half of the user's body becomes cloaked in shadows, whilst the other half remains normal in appearance. Also, as it was seen with Cobra, if user of Poison Dragon Slayer Magic is somehow capable of successfully eating a shadow element or vise versa, they will enter Poison Shadow Dragon Mode. In this form, the shadows and poisons will fuse and the user's attacks will possess the properties and destructive ability of both elements i.e. toxin infection and slicing and intangibilty. While user can damage his victim with slicing of shadow, these shadows will infect the victim. As a result, for user it's much easier to infect his opponent.

Drive is a type of Magic-amplification technique, which is common for the Third Generation of Dragon Slayers and used by its users to bring out the true power of their Shadow Dragon Slayer abilities, excluding the power boost granted by Dragon Force, yet, at the same time, seemingly enhancing his physical prowess to a degree, particularly their speed. The user cloaks their body in an aura of shadows, that completely cloaks and continuously rises from his body. With this, they are amplifying the powers of their Shadow Dragon Slayer Magic.

Aside from improved performances, the user gains the ability to morph in and out of shadows, allowing for swift, intangible movement and an erratic fighting style. This state either grants its user the ability to perform new spells or makes them stronger, as the Sabertooth Mage has been shown employing several skills only while in said Drive.
 * Dark Mode (影の滅竜魔法・暗面の覚醒 (ナイトモード), Naito Modō lit. Shadow Dragon Slayer Magic: Awakening of the Dark Side): The most unique and a secret art of the Shadow Dragon Slayer Magic. It's a very rare ability, which can be awakened by a Shadow Dragon Slayer, who reached their full potential. Because of its unique capabilities and affect on the user's body, it's highly lost and abandoned even with Shadow Dragon Slayers. As every Shadow Dragon Slayer has their own Dark Sides, which are representing their darkest and negative emotions, they can achieve a great force, from using such state. The Dark Side can take control over the user's body, how it happened to Rogue in his battle with Gajeel. With some training and reaching the peak of their power, Shadow Dragon Slayers can connect to their Dark Side, and when they will accept it as their own part, they can fully control their new-found strength. Dark Side's source are user's emotions, so the power of Dark Side is directively depend on which emotions user has. When possessed or using this Mode, the body of user attains some shadow markings, and when the user has a deep connection to his Dark Side, they can attain even more shadowed appearance, as their parts of body become covered in black-coloured shadows. When using it, both physical and magical performances of the user grows in several times, as it was shown with Rogue. The user of Dark Side attain a better control over their shadows, as well, as become more cruel and savage fighter, who relies on their own instincts and physical capabilities, which can reach the level of becoming a berserker, who doesn't matter on his wounds and body's condition and has no hesitation in greatly harming or even killing somebody. The user is also able to use some new spells, while his own spells become stronger and taking more shadows in using. As a first user of this mode for the last decade, Rogue possesses great control over his Dark Side. The Dark Rogue, as it was called by Sting Eucliffe, takes its power from Rogue's positive emotions, however used to take his negative emotions. Also, as Rogue has great control over his Dark Side, he can enter his Dark Mode fully and partially. When entering this mode partially, Rogue's appearance changes to what he had, when he was firstly possessed. With this, both of his physical and magical performances become enhanced on 50%. When entering fully, Rogue's shadow markings changes, as he gets special markings near his eyes, which Future Rogue had. His body also becomes covered in shadows, as they take the appearance of his long cape or a scarf, when Rogue faces the strongests enemies. When used on full, Rogue's power become enhanced on 100%, i.e. in four or even five times, by his words.

Dragon Force
Dragon Force (竜の力 (ドラゴンフォース), Ryū-ryoku (Doragon Fōsu)): It is an advanced ability, an ultimate form, which can be reached by an every Dragon Slayer. When a Dragon Slayer enters this form, they effectively turns into a humanoid Dragon, gaining reptilian scales and traites, such as alongated and sharper canine teeth and scale-like patterns on their skin. It is a most powerful state of Dragon Slayers, which is give them a power, that can be compated to that of real Dragon. Dragon Force greatly increases the damage done by standard Dragon Slayer spells, and grants the user access to more advanced, powerful attacks. It also drastically enhances the user's physical prowess, making them far stronger, more resistant to damage, and faster, and considerably boosts their Magic Power, which becomes visible, taking the appearance of a Dragon. When exuded at its fullest, said Magic Power takes on a violent corporeality, likely as a result of the immense amount of Magic power employed.

To achieve the state of Dragon Force, Dragon Slayer of each generation has different way to enter it: as First Generation must consume some very powerful Magical Sources of their own element, while other elements are also can be consumed, but will be similar to "poison" for the user, causingheavy after effects, for example, great pain while activation of Dragon Force Form.

Being a product of the Third Generation of Dragon Slayers, Rogue is capable of entering the one of the most powerful form of the Dragon Slayer at his will, without the need to consume strong, external sources of Magic. Such a feat greatly surprised those who had intimate knowledge of Dragon Slayer Magic. When this state is activated, Rogue body becomes much more akin to an actual Shadow Dragon's, with his whole body becoming covered in an shadow aura, which is even thicker and darker than that provided by Shadow Drive, and with thick dark intricate scale-like patterns appearing to cover the outer edges of his face, underneath and around his eyes, extending down from the side of his neck and onto the rest of his body. These are shown to be more and more uniform as they get farther from the central portion of his body, which instead bear several scattered, distinct scales, elongated and placed diagonally. These patterns serves as is dragon's scales.
