Wondrous item, rare (requires attunement by a wizard)

This pristine book smells faintly of a random scent you find pleasing. When found, the book contains the following spells: Antipathy/Sympathy , Charm Person , Dominate Person , Enthrall , Hypnotic Pattern , Modify Memory , and Suggestion . It functions as a spellbook for you.

While you are holding the book, you can use it as a spellcasting focus for your wizard spells.

The book has 3 charges, and it regains 1d3 expended charges daily at dawn. You can use the charges in the following ways while holding it:

• If you spend 1 minute studying the book, you can expend 1 charge to replace one of your prepared wizard spells with a different spell in the book. The new spell must be of the enchantment school.
• When you cast an enchantment spell, you can expend 1 charge to impose disadvantage on the first saving throw one target makes against the spell.
