After Duke became a Level 1 Arcanist, he learned that applying to become a Level 2 Arcanist requires one thousand arcane points and also involves the certification session.
Gathering points is relatively easy; the hard part is passing the certification, as becoming a Level 2 Arcanist is not that simple.
After the certification ended, Grace came over with folded arms and said, "Kid, you did well. You've reached this point even faster than Vivian did. Seems like I should have taken you in back then."
Back then, Grace said that Duke's spiritual power aptitude wasn't sufficient, so she didn't allow him to enter the Thorn Holy Tower.
But in reality, that was just an excuse. Even if Duke had a better spiritual power aptitude, she wouldn't have let him enter the Thorn Holy Tower, mainly because she didn't want the trouble.
