The Demon Master Voronum spent thirty years practicing sacred geometry in order to more fully channel his Demonic energy into the patterns required to achieve the "Heaven Blast of the Dragon".
This has allowed him to understand that the Demonic Aura does not simply need to be a representation of the Demonic Self but can be shaped freely with the right mindset.
He has also found that calling out attack names DOES seem to impart power into his energy. More research is required.
