As he used Appraisal in the items, Frank discovered that they were not conventional because they were, in fact, "Divine Materials".
But what were Divine Materials?"
Divine Materials were powerful items that grew within areas where Divine Energy flow freely, such places often grew powerful items that had greater resiliency than normal magical materials, which beings of higher existence levels used to craft powerful artifacts.
In fact, any item above B-Rank that appeared within these loot boxes was made of divine materials!
Through his Creation Skill, Frank was not even capable of replicating the amazing power of such materials… he felt like a 3-year-old trying to build a computer from zero.
However, what could Frank use them for?
After having used the Soul Weapon Creation Manual, Frank was enlightened with many ways of creating Soul Weapons, however, he needed powerful materials to make them.
