Divine Body of Dragon Phoenix Method.
Hex read the Method with care. The baron's notes implied that this Method created him. Perchance, maybe, but still.
Each of the ten steps had harsh requirements for completion. Still, each step consisted of five aspects: energy manifestation, body transformation, soul transformation, elemental fusion, and integration.
Energy manifestation required him to condense refined energy into matter. Basically, he had to turn energy, which was immaterial, into something materialistic. It required immense amounts of energy and control over the energy. A slight mistake and the energy would rip the user apart.
Body Transformation didn't mean that the user had to alter their appearance or become something other than human. According to the Baron, body transformation had two purposes: to increase the storage capacity for the transformed energy and elements while enhancing the conductory abilities.
