Regulus Corneas

Equipment

Witch Cult's Gospel (魔女教徒の福音): As a member of the Witch Cult, Regulus was the owner of a copy of the Witch Cult Gospel. Each Witch Cult Gospel was a replica of the Book of Wisdom, a book that had been in the possession of the Witch of Greed Echidna. The Book of Wisdom would provide exact details of future events concerning the Witch of Greed, essentially bestowing Echidna with a form of precognition. Unlike the original Book of Wisdom, the Gospels of the Witch Cult were imperfect replicas, meaning that, although they detailed the future of its owner, the events conveyed were subject to change and the information provided was often up for interpretation. The Gospels took the form of small black books that could only be read by their owners.

Abilities

Authority of Greed (強欲の権能 Gōyoku no Ken'nō): Regulus was able to use the Authority of Greed until his Witch Factors were taken by Natsuki Subaru following his death. The Authority itself is split into two main abilities–Stillness of an Object's Time and Lion's Heart:

Stillness of an Object's Time (物体の時間の静止 Buttai no Jikan no Seishi): The so-called Stillness of an Object's Time was Regulus' mainly offensive ability, named by Subaru. Regulus could stop the time of anything he was wearing, touching, or even his breath, which in turn stopped the object's or thing's interference from the outside world, only allowing its interference outwards and even granting Regulus the ability to freely manipulate the objects' shape. Small objects imbued with Stillness of an Object's Time could be used either as a form of platform which allowed Regulus to freely traverse on it, or be utilized as objects of imminent death and destruction as they created devastating and destructive attacks when used with malicious intent.

Dirt, sand and pebbles imbued with Stillness of an Object's Time: Regulus frequently showed the ability to pick up or kick things like dirt or sand, stopping their time and throwing them towards his enemies. As the time of these small objects was stopped, the objects effectively acted as anomalies in the world, being cut off from the flow of time. They passed through anything they collided with, no matter the sturdiness, leaving behind only small holes–if the structure was still left standing in the first place. If thrown at an individual or an animal, the objects would naturally travel through them, completely shredding and goring them, usually leaving behind nothing more than an unrecognizable pile of flesh or a bloody mist. Regulus used this ability to shred Pandora into a bloody mist during the attack on Elior Forest, roughly one century before the start of the main story. He used the same attack once more during the events of Arc 5, when he shredded Subaru's right leg, as a form of revenge for Subaru spoiling his plans and mood.

Water imbued with Stillness of an Object's Time: Though not very practical in most fights, Regulus did resort to using water, if he had the chance to do so. The ways of attacking were pretty much the same, as Regulus usually just scooped up a fistful of water and threw it towards his enemies, rendering them to nothingness. However, after being forced to engage in combat with the Sword Saint, Regulus was forced to get a bit more creative. By kicking the water in a water canal, he unleashed a devastating tsunami, hurling towards Subaru and Emilia during their escape. The tidal wave crushed everything in its path and did not stop until Reinhard cut it in half, destroying it in the process. By freezing the water from a nearby water canal in place, Regulus could pick it up with his hands, similarly to having a tatami mat made out of water. He manipulated it in a similar way as he manipulated the aforementioned water from a nearby canal, creating a giant tsunami. If needed, Regulus was also shown to be able to walk on frozen water droplets, as if he was walking on solid ground. Furthermore, by just stepping into the water, Regulus created a pillar of water with its time stopped, using it to propel himself high in the air. There was even a time when he collected the water from an entire nearby water canal, shaped it into a giant blob of water, jumped (according to Subaru, the jump itself was more akin to teleportation) onto the Third Control Tower in the Water Gate City of Priestella, reshaped it into thousands of smaller droplets and proceeded to bomb the entire district underneath him, while referring to the ongoing bombardment as "purification rain".
