I'm a volume full of a mystical art.
Want to be a Spellcaster? Try reading me for a start.
In battle, with me by your side,
To you, shall shift the tide.

I can instruct you on many magicks,
Spells, summons, maybe even a few tricks.
Flip through my pages,
You'll find I'm on the reading list of many sages.
Even Harry Potter sought after this book you see,
For Clow Reed had nothing on lil' old me!

So read a chapter, skim through a section,
I'm an essential to a Spellcaster's perfection.
Short on power? Equip me with your mage,
Watch as I turn him into an almighty sage.

But remember, Duelist, everyday my pages increase,
For magic is an art that will never cease.
