The book Marvin handed Jessica was naturally the one about Ghost Barriers that he got from the Snake Witch's library.
That kind of book can only be read by a caster with a large amount of spiritual power.
This ancient book had far more demanding reading conditions than ordinary spell books. It required a high Appraisal skill and proficiency in Ancient Common.
But Jessica was no ordinary caster.
Although she wasn't a Legend Wizard, the kind of caster that the spell was intended for, the Fate Sorceress Halo was too powerful.
In all of Feinan, Fate Power was above everything else. As long as it was a spell book for any sort of caster, she would be able to use it.
Otherwise, Marvin might not have bothered trying to get the book.
Jessica had a serious expression on her face when Marvin handed it to her.
She flipped through the pages and then looked at Marvin strangely. "Where did you find this thing?"
