Asmodean Crystal

Asmodean Crystals are a type of magical mineral that allow hellborns to access the human world.

They are mostly given to Succubi by Asmodeus himself for the demons to conduct Earth-related business and are usually disguised as part of everyday jewelry.

History
Asmodean Crystals are first referenced in "The Circus" during the song "Stolas Sings", wherein Stolas procures a book from his personal bookshelf titled "King of Lust - Asmodeus" and skims through pages detailing Asmodean Crystals.

The pages are written in runic alphabet which, when translated, reveal that Asmodean Crystals are mainly given and registered to Succubi by Asmodeus himself, allowing their users to summon a portal to the mortal realm. The book also notes that the crystals are often worn in jewelry.

Asmodean Crystals make their first physical appearance in "Unhappy Campers", where Blitzo forces a succubi to use an Asmodean Crystal disguised as a buttplug to summon a portal to where his sister was. Barbie Wire later uses her own Asmodean Crystal, which is disguised as part of her wristwatch, to remove her Human Disguise and then to return to Hell.

Trivia

 * Similar to Stolas's Grimoire, the crystals have portal-creating properties.
 * This may explain how Verosika Mayday, her posse and Vortex are able to go yearly to Earth as well as in "Spring Broken".
 * It is currently unknown if Loona, Vortex and Stolas also have access to these crystals, as none of them are succubi but have the ability to change into human disguises, however it's possible they can do so via magic rather than use of the crystals.
