 When he knew about Enfrea’s innate ability, he had fantasised about the possibility of obtaining it by activating 「Wish Upon a Star」. This speculation was not wrong. In this world, 「Wish Upon a Star」 had already become a magic which made the realisation of one’s innermost desires possible. Although it would be based on the value of the consumed experience, 「Wish Upon a Star」 had become a magic which made the impossible possible. Moreover, if five levels were consumed—— five-hundred percent of experience, the magic would even enable the realisation of even stronger desires.

It makes the impossible possible now, so he can use it to learn other spells or even Other Classes but its based on how much XP he is willing to sacrifice.
