For a brief moment, Rod almost thought he was doomed to become the King of Devouring Excrement like Asa. Fortunately, he quickly understood the description of Star Energy.
The role of [Glutton] is very clear: devour ash and generate a specific substance.
The "ash" here refers to Monster Ash.
After a monster is killed, the foundation of its existence collapses, Black Fog undergoes Quantization, the Source returns to the Void, becoming once again a formless and intangible existence, and the power remaining in the monster congeals into Monster Ash. This is the purest form of Life Energy, generally used to create Potions and Fuel Elements, but the useless residues turn into ash, which is what the [Glutton] needs to devour.
