Babbling Book

This ancient leather-bound tome radiates arcane power and manic glee in equal measure. Its pages are etched in ever-shifting ink, and its eyes—yes, it has eyes—blink open whenever it senses spellcasting nearby.

Sentience. This excitable, leather-bound spellbook has a singular obsession: casting spells. The Babbling Book is sentient and Chaotic Neutral with an Intelligence of 16, a Wisdom of 8, and a Charisma of 10. It has hearing and Darkvision out to 60 feet. It speaks Common. Its voice is light and jolly. The book constantly urges its wielder to use magic and gets restless if ignored.

Spells are fun! The Babbling Book has 5 charges and contains 10 spells (listed below). As a Magic Action, you can command it to cast one of these spells, expending a number of charges based on the spell’s level. The book regains 1d4+1 charges daily at dawn. The book is the caster, but it can target you with any of its spells. The spell has a +6 to hit and a save DC of 14 but doesn't require Material components. It holds its own concentration, but you make the concentation checks using your Constitution when you take damage.

Ooh! This One! When you use the Babbling Book to cast a spell, roll 1d6. On a roll of 1, the book ignores you and picks a different spell "for fun", spending the required charges.
