Cage

Billy couldn't use Appraisal, but he could tell that the walls were at a high level. So, he tried to use his power to move, take the mana from the walls and turn it into an experience for himself. He failed…

"You think that you can use your pathetic powers on our Creation and obtain results?"

"It looks like a few years of success and victories against weak beings got to your head."

"We have been alive for thousands of years, and it would be an embarrassment for us. If someone powerless like you could do anything against it."

"Shut up. No one asked you anything," Billy said.

Billy knew that it wouldn't be easy, but he had to test it Anyway. Regardless, he just had to keep improving his powers, and eventually, his magic would be powerful enough to affect the whole tower. Still, Billy felt that things would be more effective if he could also learn Lucyna's powers.
