Courtier's Pillow Book
This elegant journal has a detailed social dossier on the owner's acquaintances. When you make your daily preparations, you can inscribe a secret or embarrassing foible about a specific individual that you know to be true or have on good authority.

Effect If your next action is to cast a mental spell on a target about whom you've written an entry in the book, you can state that secret or foible before Casting the Spell to give the target a –1 circumstance penalty to their saving throw against the spell. The inscription then disappears from the grimoire.
Traits
Spellbooks are useful tools for any magic user to write down incantations and runes of power, but where most spellbooks are nothing more than ink on parchment, grimoires have absorbed the magic of the spells within—magic that knowledgeable spellcasters can use to augment their spells.
Something with the magical trait is imbued with magical energies not tied to a specific tradition of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
