Authority - Re:Zero
Authorities are abilities used by Sin Witches and Sin Archbishops that manifest in people after absorbing Witch Factors. Loi hinted at the ability to control the White Whale due to Daphne 's Witch Factors, and it is assumed that Sin Archbishops inherit or receive Authorities that originally belonged to Sin Witches.
Authority of laziness
Notable users of this authority are Subaru Natsuki None Pételgeuse Romanée-Conti an Archbishop of the Sin of Sloth, Satella the Witch of Envy, and Sekhmet the Witch of Sloth.
The user can emit a black wave into the surrounding area that aims to corrupt the minds of the affected people.
Invisible Hand - The user manifests invisible hands that vary in power, area of effect, and quantity, depending on the user. Satella the Witch of Envy was able to control 2,000 hands at once according to Palet . The user can also make their hands pass through objects if they concentrate hard enough. Subaru gains a much weaker form of this ability that he calls Invisible Providence. Subaru is only able to control a single hand at close range using this ability.
Authority of Gluttony
Notable users of this authority are Ley Baitenkaitos, Roy Alphard , and Louis Arneb who are all Archbishops of the Sin of Gluttony and Daphne the Witch of Gluttony.
The user can eat a target's name and memories by first touching the target with their left hand, then licking the palm of the same hand. Experience, talent, and likes and dislikes in human relationships are "eaten" by the authority user, allowing them to use the target's abilities and memories. However, eating a false name in this manner causes the user to experience severe nausea. This ability has three consequences.
First, eating a target's name erases them from the world, erasing their very existence and destroying all human relationships, preventing the use of magic, and voiding any spiritual contracts. In comparison, consuming only a target's memories causes amnesia and effectively transforms the target into a different person. Finally, eating both the name and the memories renders the target an empty shell that no longer eats, excretes waste, or ages.
Eclipse - An ability under the authority of Gluttony that is considered the user's trump card. It is confirmed to have two types: Solar Eclipse and Lunar Eclipse. The specifics of this ability have not been explained at this point, but Otto Louis described it as Ley becoming sinister on another level. Indeed, Ley's speed had increased enough to give the illusion of moving in an instant. Louis in Ley's form claimed that his current body was incapable of properly using this ability, but still boasted of being able to completely destroy his opponents.
Authority of Greed
Notable users of this authority are Subaru Natsuki, Regulated Corneas who is an Archbishop of Greed's Sin, and Echidna who is the Witch of Greed.
This authority is primarily manifested through an ability called Time Stillness. The user is able to stop the flow of time affecting themselves, anything they are wearing, anything they have touched, or even their breath. Targets of this ability cannot be affected by outside forces, and any attacks against the user in this state are negated. However, the user is still able to interact with the rest of the world with increased efficiency. For example, a wave of the user's hand can cut through anything in its path, air released from stillness causes shockwaves, and thrown gravel acts as unavoidable shots. The difference in time flow also allows the user to travel at extremely high speeds during normal time. This ability puts a strain on the user's heart as it also stops and can be fatal if used multiple times.
Little King is an ability associated with the Authority of Greed that bypasses the weakness of an object's Stillness of Time . It allows the user to fuse their heart with a person in their kingdom, which in practice is any woman the user has confirmed as their wife. Destroying the fusion places the burden back on the user with no other discernible effects. No other specific conditions or area-of-effect limitations are currently known for this ability.
Cor Leonis , also known as "Lion Heart," is an ability under this authority that Subaru acquired in Arc 6. It works in an inverse manner to Petit Roi and allows Subaru to take on the burdens (physical and mental) of others. By doing so, he is able to temporarily increase the target's combat abilities. It is limited to only working on people Subaru has an emotional connection with. He must also be able to sense them through his authority. This is described as seeing people as points of light, and he can further use this to deduce everyone's relative positions to himself as well as their emotional states.
Authority of anger
Notable users of this authority areSirius, an Archbishop of the Sin of Wrath, and Minerva, the Witch of Sin.
Users of this power can share or transmit their own emotions and feelings to others. Polarizing emotions such as anger or sadness can be used to take control of a group of people or transmitted through a group to escalate emotions to the point of madness. In extreme cases, if one person in the affected area dies, the user can force others in the area to die in the same way.
Chain Control or Fire Control is a subset of this ability that allows the user to control chains wrapped around their body in normal chain form or after transforming them into fire.
Authority of Lust
Notable users of this authority are Capella Emerada Lugnica a Sin Archbishop of Lust and Carmilla the Witch of Lust.
The ability under this authority is known as Variation and Change , which allows the user to transform themselves and others into various forms. Additionally, users of this ability can use it to heal themselves by simply transforming the damage they take. Replacement parts regenerated through this method dissolve after being replaced.
Authority of Vain Glory
Pandora, the Witch of Vain Glory, is a notable user of this power. This power allows the user to rewrite a phenomenon in their favor as many times as they wish. This includes undoing their death, instantly burying people in the ground, and altering their memories. The black serpent cannot be controlled through this ability, but can be directed to any location the user desires.
Authority of Melancholy
Hector, the Sorcerer of Melancholy, is a notable user of this power. This power allows the user to create an invisible gravity field that crushes both living beings and magic.
