Gluttonous Inferno and Advanced Wizard!
[Magical Powers: Inferno Ascension Technique (Level 4: Gluttonous Inferno, 45%)｣
[Level 4 - Gluttonous Inferno: The flames of Gluttony empower the user to devour the life, spiritual, and mental force of chosen targets for themselves, refining it with the purest hellfire to form nutrients for themselves. The users can also grant this converted and purified essence to others with varying effects.]
That's right, Dante had achieved the fabled devouring all on his own!
Did this mean he could ditch the Absorption of the Apocalypse World? The answer was unfortunately, no. The Gluttonous Inferno did not give him energy that raised his body's quality or stats.
What it did was allow him to turn anything that had energy into purified essence for himself. The essence in this case was used for sustenance as well as to power his various abilities.
