I forget to take "Weapons Mon 1st "

Can i know how to get back the weapon mon 1st ?
I already miss it,and now i have the "ragnarok" plane.
Is that any chances to make the "Lion Heart" without the book? Or can i get the book?

you can get weapons without the books as long as you have the stuff.once you have the items the weapon appears in the store.the books are just help and guidelines.

You can buy it from the book store in Esthar if Tonberry King has learned the Familiar ability.
