This is a dangerous and fearful power Luchia possessed in her Alternate Form. This is also the representation of of the Black Plague itself that can kill anyone who breathes in the infected air. The Magic allows her to manipulate black fog or mist, even the damage level of it. The appearance of the magic is similar to Sky God's, but different, it overall appearance is black fog or mist currents.
When not using full power, it powerful enough to make anyone unconscious and can be a powerful shield to block destructive power of Mavis's Yajra and Natsu's flame. It is stated to be the most rarest ancient spell and akin to Ankhseram Black Magic, but Luchia can used it at will. Most of the mist of fog come out from her sleeves but no, it actually produced directly by utilizing an amount of Divinity Power than Magical Power in her palm.
This magic also allows her to be invulnerable, her body can be made of black mist, meaning every attacks on her will be useless, except for Mavis's Yajra. She also made her copies of her with her mist, her mist is actually is can be gunpowder-like mixed mist after Natsu absorbed Mavis's Yajra power and combining his fire magic causing a huge explosion. This is the Absolute Magic that no one could surpassed if there's someone who possessed the same level as her magic does, example, Mavis.
