This is a mad idea!
Would work well combined with
Johnstone's spellbook creation move:
My spellbook… (choose up to 4 options):
? …consists of multiple volumes.
? …constantly reorders its own contents.
? …has a reputation.
? …is dedicated to a specific extraplanar entity.
? …is beat to shit and falling apart.
? …is bound in human skin.
? …is engraved and decorated with gold.
? …is lavishly illustrated.
? …is made of metal.
? …is my own creation.
? …is perfumed and scented.
? …is stolen.
? …is written in a dead language.
? …was made from the corpse of a fantastic beast.
? …was written by demons.
? …was written in human blood.
By default, your spellbook can hold up to a dozen spells or rituals. Give it a name and choose up to 2 tags for it:
? Alive: Your spellbook is a living thing (+alive).
? Copy: There are multiple copies of this book in existence.
? Encrypted: Written in code that cannot be read by others without powerful magic.
? Inconspicuous: Does not look or read like a magical tome.
? Insight: Grants +1 to rolls involving one type of magic when consulted.
? Large: Holds up to two dozen spells or rituals but is bulky and cumbersome.
? Limitless: Holds an infinite amount of non-magical writing.
? Monograph: Choose one subject from the Sage's list of specialties. Your spellbook contains extensive information about this topic.
? Poisonous: Those who touch it, save for you, are poisoned. Choose a poison type.
? Secure: Magical locks or wards prevent others from opening it.
? Small: Holds half a dozen spells or rituals but is easy to conceal and transport.
? Trapped: Those who open or read it without your permission suffer harm (2-harm intimate; applied, magic, trap). Choose a damage type.
? Unusual shape: You spellbook is not a book. It is a scroll, perhaps, or a memory cube, a box full of intricate clockwork, a collection of engraved coins or knotted strings, or a deck of playing cards that must be laid out in specific patterns.
? Warded: You always know where your spellbook is and who touches it.
