Experience

Vale was unaware of their thoughts but even if he knows what was in their minds, it wouldn't really matter.

As soon as the Darkness Path Class started, Vale informed Professor Lucius about his accomplishment giving the latter a bit of surprise.

Some of his classmates, who didn't hear his conversation with Lisa and the others, looked at him with wide eyes.

"You succeeded? That's good to hear… Although the curse has already weakened a lot, there's no saying whether it could reappear once more. Alright, show me your Darkness Manipulation. For those who want to sense it properly, enter your Phantasm State as well. Your normal eyes may not work efficiently in this case."

"Yes, Professor!" The class answered as they indeed wanted to see how the Darkness Manipulation works for a beginner like Vale.
