So... I'm playing through Abomination Vault and we recently picked up the Magical Artifact The Whispering Reed right here.
The important thing is the destruction part.
It was just a really funny idea to me... but what if a Magus used the feat Raise a Tome-
You raise up the book you're holding and flip it open to defend yourself and expedite your studies. The book remains raised until the start of your next turn. While you have a book raised, you gain a +2 circumstance bonus to AC and a +1 circumstance bonus to Recall Knowledge to identify creatures using a skill related to the subject of the book (Arcana if you're using your spellbook). This bonus is in addition to any item bonus the book normally gives to the check.
If you have Shield Block, you can use the tome for that feat (Hardness 3, HP 12, BT 6) as though it were a shield. Whenever you use an ability that allows you to Raise a Shield, such as Emergency Targe, you can Raise a Tome instead, changing any requirements that normally require a shield to apply to your book.
As a shield and then have an enemy break the tome. It would curse them right?
