It still took Damian another two months to fully grasp the chaos spell he had been shown. Learning from his previous mistakes, he limited the practical application to times when he was alone—either in his personal lab late at night or in the privacy of his room.
The chaos spell was nameless, so Damian referred to it as "The Eroding Spell" due to its ability to erode any inanimate object it targeted. He was cautious, refraining from using it for anything other than understanding its features and fully breaking it down. To his relief, the spell didn't affect living beings or any tool or weapon imbued with mana. It seemed the spell's eroding function was inherently incompatible with anything possessing a significant amount of mana.
What irony that the spell itself used a shit ton of mana to activate but couldn't go against it..
