Art was acquirable once an Awakener experienced a Temporary Awakening state, and each level of the spells corresponded to their rank.
As of now, Kopi had a Divine Rank Art inherited by Elder Isolde, but it didn't mean he wouldn't create another one.
In fact, with the existence of the Extraction, he was confident he would become a Battle Mage or a Combat Mage, whatever it was called.
Therefore, Kopi aimed to create as much art as possible.
After all, it was necessary with the existence of Mana Aura.
Mana Aura aids the awakener, even other beings who possess it, to attract as many mana as possible, increasing their sensitivity to mana and the absorption process.
If Kopi didn't have a single trump card, this battle was already a disadvantage to him.
He was thankful that his opponent underestimated him.
