Books - Ye Booke of Polymorphe

Before I start rambling on the last of the magical grimoires that, for the moment, are accesible in the game, I remit all people interested in the spell Crondor's Fabulous Detection to my previous entry on the said spell, as I think a change has been implemented in it of late: a gold ring is now required too as a component. I still haven't tested it, but the output of spellcheck now certainly mentions it as a 'component':

The spell "Crondor's Fabulous Detection" is a miscellaneous spell requiring a gold ring and a staff.
For stage one using the staff skill, you would most certainly succeed.
For stage two using the gold skill, you would most certainly succeed.
For stage three using the turning skill, you would most certainly succeed.
You complete checking the stages in the casting for Crondor's Fabulous Detection.

And now, back to sorcerous books. 'Ye Booke of Polymorphe' appropiately honours its subject-matter by having many changing forms, alternating between them from time to time. When in the room with the book, you'll get from time to time a line that says:
'The book is so bored that it decides to change its shape slightly'.
After which looking at it will give another new description.
The changes are of two classes: some are specific to this grimoire (and the ones I've been able to find are provided below); others are borrowed from the other spell books in the game (of these, I've seen it addopt the forms of Thee Dyscyplyne of thee Stoane, of the Fire tome and of the 'Occult Primer' guide, but I imagine it can alternate through all of them...).

A closed chitin-covered brochure is on the floor.

This is a small black brochure. Its cover seems to be made of a giant insect's exoskeleton.

Small octarine sparks run to and fro across the black surface of the brochure.

or

A closed furry book is on the floor.

This book is covered with soft brown fur and equipped with several sharp-looking boney thingies. If it grows some more fur, claws and fangs, you wouldn't let your pet cat near it.

Octarine sparks play in the fur that covers the book.

or

A closed quivering tome is on the floor.

This tome seems to live its own life: it shivers, quivers and tries to look completely independent of you, this room, and the rest of the world.

A single octarine spark travels across the surface of the book in an independent manner having as much fun as it can.

or

A closed weird dusty grimoire is on the floor.

This is a dusty grimoire with a pair of eyes bulging on its surface. The eyes do their best to watch your every move.

Pure octarine radiance pulses menacingly in the pitch black pupils of the book's eyes.

or

A closed magic tome is on the floor.

This book is an old, leather-bound tome with some strange designs on the front.

Octarine seeps from between the covers.

or

A closed friendly noisy book is on the floor.

This book doesn't want to lie where it should be. Instead, it tries to nuzzle you affectionately and says woof and arrf every now and then. Perhaps you can call it Fido.

On the surface of the book, two octarine dots are busy chasing each other.

or

A closed huge leather-bound tome is on the floor.

This huge tome is bound in leather that looks and feels suspiciously close to hardened human skin.

Fingerprint-like patterns on the cover glow faintly with octarine.
