Damning

"Welcome, young Ramurtha, to your Damning."

- Satan Damning(also called Demonization) is the process by which new demons are made. it is sometimes used by Demons to increase their power, but can also be used by other participants.

Components(Demons, regular Earthlanders/Edolisians)
the subject needs to be laid down inside a pentacle typically used with demon summoning(Come To Me!) and dismissal(Away With You!) however, instead of preforming the particular incantations and Wards, the pentacle merely has the subjects name inscribed in the middle. The subject will then be circled by a demon of equal or greater power to the class they will become, however, if you already a demon, you may only raise one class at a time, and you have to be maximum level in a class to move up (level can be improved via training) the higher-up Demon will chant in a strange dialect that roughly translates to "Great power, awaken inside!" repeatedly. there will be a great surge of magical energy coming up from below and entering the subject's body, then the ritual is complete.

Components(Devil slayers)
Same as before except the process will force them to enter Devil Sync. Their tatoos that signify a Devil Slayer will change to a Demons mark briefly before fading entirely, with the devil characteristics remaining. The subject will then gain all the strengths and weaknesses of a Demon, except that their Devi; Slayer Magic will leave them and be replaced by Devil's Magic. They then will be a full demon. The class achieved by a Devil Slayer during Demonization is entirely random.

Trivia

 * Unlike possession, the newly created Demon will act of it's own free will.
