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. Witch Factors are the antithesis of Od Lagna and the Authorities granted by them can be considered the backward compatibility of Divine Protections, according to Beatrice. According to the author, no Divine Protection can be as strong as an Authority.

The Witch Factors and Authorities used by the Sin Archbishops originally belonged to the Witches of Sin, and according to Louis, there is no real difference between the two as they're all just "good-for-nothings compatible with the Witch Factors" that are called differently due to different eras and positions. 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".

If a Witch factor is forcibly inserted into someone incompatible with it, it will greatly alter their personality as seen with Satella and Petelgeuse. It's shown that there are different ways to receive the Witch Factors. Petelgeuse got his from a small black box while in Subaru's case, the Witch Factors of Sloth and Greed latched onto him as soon as their respective hosts died, which suggests that the Factors can manifest in a physical form (as black gue) or in a non-physical form (in Subaru's cases).

Authority of Sloth
The Authority of Sloth (怠惰の権能 Taida no Ken'nō) was formerly used by Sekhmet, later by Petelgeuse Romanee-Conti and currently used by Natsuki Subaru.
 * Sloth (怠惰 Taida) (Used by Petelgeuse Romanee-Conti)
 * 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. This ability is only present in the Web Novel of arc 3.
 * Unseen Hand (見えざる手 Miezaru Te) (Used by Sekhmet and Petelgeuse Romanee-Conti)
 * 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. It can also phase through objects if the user concentrates enough. The Unseen Hands differ between users with Sekhmet having the most advanced, fast and deadly version we know of and Petelgeuse being able to produce up to one hundred Unseen Hands which are slower but powerful enough to crush fully grown threes.
 * Invisible Providence (インビジブル • プロヴィデンス  Inbijiburu Purovidencu) (Used by Natsuki Subaru)
 * Subaru can cause physical interference by creating an invisible force field in the shape of a hand that can phase through objects if he focuses his thoughts. This Authority heavily aches to Petelgeuse's Unseen Hands though he is only able to control one hand and its range and damage are minimal and it also sprouts out of his chest as opposed to his back. Despite it's eerie similarity to the aforementioned Sin Archbishop's very own cherished Authority, Subaru's Invisible Providence is vastly inferior compared to other Authorities of Sloth we've seen so far.

Authority of Gluttony
The Authority of Gluttony (暴食の権能 Bōshoku no Ken'nō) was formerly used by Daphne and Lye Batenkaitos and is currently used by Roy Alphard and Louis Arneb.
 * Gluttony (暴食 Bōshoku) (Used by Lye, Roy and Louis)
 * 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.
 * Killing the user will not result in the memories and names of all their victims to return back to their original owners.


 * Eclipse (蝕 Shoku) (Usedy by Lye, Roy and Louis)
 * 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. Lye, 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, Lye, Roy and Louis do not gain their victims' Divine Protections, Spirit Arts or Authorities.
 * Solar Eclipse allows the holder to harvest his victims' names 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 Lye 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.
 * Daphne's Authority of Gluttony 
 * There currently is no concrete example of Daphne using her Authority of Gluttony in the official novelisation. But considering how she is ranked just behind Typhon in terms of strength, it's safe to assume she holds considerable power.
 * In the Web Novel, Daphne can be seen using her Authority of Gluttony and making people feel extreme hunger by touching or looking at them. Just one eye was enough to force Subaru to experience it, causing him to eat his arm and try to lick his own blood while ignoring everything other than the thought of eating. Despite this, Echidna described Daphne's left eye as "nothing much", stating that she was a terror if she used her right eye or if she "ate" him.

Authority of Greed
The Authority of Greed (強欲の権能 Gōyoku no Ken'nō) was formerly used by Echidna, later 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) (Used by Regulus Corneas)
 * The user can stop the time of themselves or anything they're wearing, touched, or even their breath. This stops any interference from the outside world and only allows the user's interference outwards. While this ability is active, the user cannot receive any sort of damage, no matter the power or destruction of the attack, as seen when he took on Crusch's One Blow One Hundred Felled sword technique that was able to penetrate even the White Whale's sturdy hide and came out unscathed. If the user waves their hand, anything in its trajectory will be cut no matter the toughness. The atmosphere released from the Stillness can cause shock waves 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.
 * Lion's Heart (獅子の心臓 Shishi no Shinzō) or Small King (小さな王 Chīsana Ō) (Used by Regulus Corneas)
 * 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 (used by Natsuki Subaru)
 * 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) was formerly used by Minerva and is currently used by Sirius.
 * Wrath (憤怒 Fundo) (Used by Sirius)
 * 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.
 * Minerva's Authority of Wrath.
 * Minerva is able to heal others by hitting them with any part of her body, though her ability has a side effect of a calamity occurring in a different part of the world every time she does so. It also seems to grant to her super strength and speed which leaves shockwaves in her wake.

Authority of Lust
The Authority of Lust (色欲の権能 Shikiyoku no Ken'nō) was formerly used by Carmilla and is currently used by Capella Emerada Lugnica.
 * Variation and Change (変異と変貌 Hen'i to Henbō) (Used by Capella Emerada Lugnica)
 * 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.
 * Faceless Bride (顔のない花嫁 Kao no nai hanayome)
 * Carmilla was able to captivate people, making them so absorbed in watching her that they wouldn't notice if someone stabbed them or if they were burning. She can also cause people to see and hear her as what they want to see and hear, such as when Subaru saw and heard her as Rem. She also seems to be capable of making people "understand feelings" like love, as seen in the Witch's tea Party when she used her Authority of Lust to help Subaru understand Satella's love for him.

Authority of Pride
The last known user of the Authority of Pride (傲慢の権能 Gouman no Ken'nō) was Typhon. The current holder of the Witch Factor of Pride and the user of the corresponding Authority is unknown.
 * Typhon can break apart her target's body if she determines that her target feels guilty of something. The concept is very subjective, making her one of the most dangerous Witches of Sin.
 * If a person feels guilty, Typhon will deliver punishment and condemn them, even if the deed itself isn't something the person should be punished for.
 * If an opponent hits her, Typhon can activate her Authority and "destroy" the attacker as long as all the conditions are met. The Authority works instantly but it does not nullify the actual damage, as seen when Minerva hit Typhon and instantly, her hands crumbled to dust while Typhon was blown back by the sheer force of the attack.
 * It is implied that Typhon takes the sinner's body parts as "compensation for their sins".
 * It also has no effect on living things that possess limited or no capacity to think like Daphne's Centipede Coffin.

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

Authority of Melancholy
The last known user of the Authority of Melancholy (憂鬱の権能 Yū'utsu no Ken'nō) was Hector. It is unknown if the Witch Factors still belong to him or not.
 * The user can create an invisible gravity field like ability that is able to crush both living things and magic alike.
