Grimoire Infinitus

Several of these spellbooks with gilded pages and silver-plated covers were created during the Age of Arcanum, but only one has been found since the Calamity ended. The book has an infinite number of pages, is three inches thick, eight inches wide, twelve inches long, and weighs three pounds.

Most of the book is blank, but the following spells are recorded in the first pages of the tome: Alarm, Antimagic Field, Bigby's Hand, Blight, Charm Person, Confusion, Control Weather, Create Undead, Detect Thoughts, Enlarge/Reduce, Fear, Foresight, Gaseous Form, Glyph of Warding, Legend Lore, Leomund's Tiny Hut, Mass Suggestion, Mislead, Misty Step, Mordenkainen's Faithful Hound, Prismatic Spray, Ray of Enfeeblement, Silent Image, Teleport, and Thunderwave.
