It would appear that Spell Card crafting fell under Rune Architecture.
What were Spell Cards anyway?
Simply put, there were rare cases where devils were born without innate abilities, and nearly eighty percent of a devil's overall potential depended on the innate power they awakened.
Whether it was combat oriented, sorcery aligned, or utility based, everything hinged on that initial awakening.
Although Lesser Devils suffered from this the most, even Noble Devils were not exempt.
So the Occult Tower approved the Cardmaker profession and allowed a new temporal innovation, the Spell Card, to enter circulation.
By channeling reishi into a blank card along with specific materials, it became possible to create an artificial grimorie and unleash the embedded spell when required or in combat.
In essence, it was the act of coding reishi into a physical object.
You might think something like this would be easy.
How difficult could channeling reishi into a physical medium be?
