Item Description:
"Its birth is an incredibly fortuitous accident, a crude imitation concocted by combining mysterious inscriptions in the most brutish and ignorant manner—a task even a Jackal and Wolf could accomplish. But, congratulations are in order nonetheless, for you now possess a 'psychic weapon' in the truest sense of the term.
Perhaps you could give it a name to commemorate this moment."]
"It can be named, huh."
