Authority

Authorities (権能 Ken'nō) are various abilities the Witches of Sin and Sin Archbishops use.

Information
Authorities can be manifested within people after they take in Witch Factors. Currently, only the Authority of Pride hasn't been revealed as the seat is vacant. As Ley is mentioned to be able to control the Hakugei because it obeyed Daphne's Witch Factors, it can be assumed that the Witch Factors and Authorities used by the Sin Archbishops originally belonged to the Witches of Sin. Furthermore, the powers of each authority are shaped into existence based on a compatible holder's desire, however the hosts have no control over what kind of ability is born out of their "sin".

Authority of Sloth
The Authority of Sloth (怠惰の権能 Taida no Ken'nō) was formerly used by Petelgeuse Romanee-Conti and currently used by Natsuki Subaru
 * Sloth (怠惰 Taida)
 * The user can let out a black wave toward their surroundings, corrupting the minds of those who have no knowledge of Spirit Magic. Those affected experience hallucinations, auditory hallucinations, and severe pain, then expose the whites of their eyes, foam at the mouth, and are nearly driven mad.
 * Unseen Hand (見えざる手 Miezaru Te)
 * The user can cause physical interference by creating an invisible force field in the shape of a hand. The effect area, power, and number of hands is based on the user, and according to Puck, the Witch of Envy was able to manifest 2000 hands at once. It can also phase through objects if the user concentrates enough. Subaru later renames this technique as Invisible Providence (インビジブル・プロヴィデンス Inbijiburu Purovidensu), though he is only able to control one hand and its range is minimal.

Authority of Gluttony
The Authority of Gluttony (暴食の権能 Bōshoku no Ken'nō) is currently used by Ley Batenkaitos, Roy Alphard, and Louis Arneb.
 * Gluttony (暴食 Bōshoku)
 * The user can eat the name and memories of their opponent. To eat a name, the user touches them with their left hand, then licks the palm of the same hand. Things such as experience, talent, and the likes and dislikes of human relationships serve as food for the user, allowing them to take advantage of any abilities or memories their opponents had. However, if the user eats a fake name, they are plagued with severe nausea.
 * Those that have had their names eaten have their existences erased from the world, destroying any human relationships along with preventing the use of magic and negating any contracts with Spirits.
 * Those that have their memories eaten become amnesic and any characteristics they may have had are reset, effectively making them into a different person.
 * Those that have both their name and memories eaten simply become a shell, and although they live, they no longer eat, excrete waste, or age, putting them in suspended animation.


 * Eclipse (蝕 Shoku)
 * Eclipse is considered to be the trump card of gluttony. It is divided into two types; Solar Eclipse (日食 Nisshoku) and Lunar Eclipse (月食 Gesshoku).
 * Lunar Eclipse allows the holder to use the victims' memories and harvest their skills and knowledge. Ley, for example, used Lunar Eclipse to boost his physical strength and perform numerous martial art techniques including The Palm of the Fist King and the Leaper technique. It is worth noting that by eating a person's name and using Lunar Eclipse, Ley, Roy and Louis do not gain their victims' Divine Protections, Spirit Arts or Authorities.
 * Solar Eclipse allows the holder to harvest his victims' name and transform their appearance accordingly. Louis, for example, transformed into Neiji Rockheart and numerous other victims she and her two brothers had eaten throughout the years, using her sibling's body. Both Ley and Roy dislike having Solar Eclipse used on them. According to them, Solar Eclipse made them feel as if their selves were being damaged, making it unendurable.

Authority of Greed
The Authority of Greed (強欲の権能 Gōyoku no Ken'nō) was formerly used by Regulus Corneas and currently used by Natsuki Subaru.
 * Stillness of an Object's Time (物体の時間の静止 Buttai no Jikan no Seishi)
 * The user can stop the time of themselves or anything they're wearing, touched, or even their breath. This stops any interference from outside and only allows the user's interference outwards. This negates any attack against the user, and if the user waves their hand, anything in its trajectory is cut no matter the toughness. Atmosphere released from the stillness can cause shockwaves, gravel thrown around can become inevitable shots, and it can enable the user to travel at extremely high speeds. Normally, multiple uses of this ability can be deadly as the user's own heart also stops, however it can be circumvented when combined with another of the Authority of Greed's abilities.
 * Small King (小さな王 Chīsana Ō)
 * The user merges their heart with one of the people of his kingdom or in other words any woman that the user has confirmed to be their wife. With this, the user can use the effects of Stillness of an Object's Time as long as they wish to. As it is only a pseudo heart, even if the merge is destroyed the only aftereffect is that the user bears the burden again. Any conditions or effect area haven't been shown.
 * Cor Leonis
 * Alternatively known as "Lion Heart". A reverse positive form of "Small King" which Subaru gained in Arc 6. As such it works inversely to how Small King does in which Subaru takes on the burdens of others, be it physical or mental by transferring them to himself temporary in-exchange for increases in their combat abilities. It only works on people Subaru has an emotional connection to whom he can sense by seeing them as points of lights when the authority is active. It can be used to derive the relative positions of everyone and their emotional states to himself.

Authority of Wrath
The Authority of Wrath (憤怒の権能 Fundo no Ken'nō) is currently used by Sirius.
 * Wrath (憤怒 Fundo)
 * The user can share or transmit their emotions and senses to others. After polarizing emotions such as anger or sorrow, the user can transmit it to any people in their vicinity, either taking control of them or resonating a certain emotion between a certain amount of people to raise it to the point of madness. Also, since the user can share senses such as distress or pain, if anyone dies within the effect area the user can force others within the same area to die the same way.
 * Chain Control (鎖操作 Kusari Sōsa) or Fire Control (炎操作 Honō Sōsa)
 * The user can control the chains wrapped around their body or transform the chains into fire and control them.

Authority of Lust
The Authority of Lust (色欲の権能 Shikiyoku no Ken'nō) is currently used by Capella Emerada Lugnica.
 * Variation and Change (変異と変貌 Hen'i to Henbō)
 * The user can transform themselves or others into various things. This ability can also be used to heal by transforming damaged parts into uninjured parts, with Al mentioning that Capella was able to heal "after I cut her head off and crushed her heart", and any spare parts generated through healing dissolve on their own.

Authority of Vainglory
The Authority of Vainglory (虚飾の権能 Kyoshoku no Ken'nō) is currently used by Pandora.
 * The user can rewrite phenomenon in their favor as many times as they want. Using this, they can negate their death, bury people into the ground instantly, teleport people without leaving any trace of their actions behind, and change people's memories. Although the user can't control the Kurohebi with their power, they are able to direct it to wherever they want.

Authority of Melancholy
The Authority of Melancholy (憂鬱の権能 Yū'utsu no Ken'nō) is currently used by Hector.
 * The user can create an invisible gravity field like ability that is able to crush both living things and magic alike.
