Kapitel 757: Killing One Tension For Another

The concept behind generating Aura stemmed from how one's body, which had been enhanced by growth through Stages, could strain the mana core into concentrating vast quantities of mana into Aura.

The Aura produced when one became an Advancement Stager was rough, because their body was less refined, only several degrees stronger than when they had been a Foundation Stager. Therefore, with the highly inefficient method the body resorted to in order to influence the mana core into Aura generation, only an inferior product (Full Body Aura), whose production weakened the mana core's capability very quickly, could be born.

This was why Full Body Aura could only be used once a day, that was in one go. Even if one stalled, it couldn't be used for long within 24 hours.
