Vale returned to his dormitory after having his lunch with Leonore and the others.

He actually asked Leonore if she was aware of the details of Wilfred's Fear Stream and Spectral Hands. 

Unfortunately, because these couple of spells weren't easily seen, she can't provide a satisfying answer. Leonore only knows what was written in the Dark Spell Book.

The Fear Stream affects the mind of the target as the name suggests while Spectral Hands summons a hand that seems to have come from Hell. The summoned hand was also capable of touching the souls of the target.

Based on what they know, the Spectral Hands are made for offensive moves while Spirit Hands was for defensive and the Ghost Hand was for support. 

  Since Ghost Hand's Advanced Realm is already so strong while being a support-type only, it means that the Spectral Hands' higher realm is much stronger than the Ghost Hand. 

Vale sat on the couch in the living room of his dormitory.
