Vincent did his best to explain the origin of the Fairer Potion.
Of course, he can't tell that he made it since he would certainly be questioned how it was made and there was no way he could answer that.
He can only reveal that he has a team in his residence that was able to successfully produce it. For now, Severin can only take all the credits since he can't mention his ability to modify potions as well.
Although Faviona and her disciple are already somewhat aware of his ability regarding this, he decided to just limit the information he could give to these Archons.
"Very well… We'll wait for the appraiser before we try your potion, Vincent." Ignacy replied.
Although he trusts his disciple about this matter, the other Purple-Robed Grand Magus may not be satisfied with only an explanation.
Getting a Master Appraiser to inspect the potion is certainly the best option that they have.
