Wondrous item, rare (requires attunement by a wizard)

This thick book is bound in dark leather, crisscrossed with inlaid silver lines suggesting a map or chart. When found, the book contains the following spells, which are wizard spells for you while you are attuned to the book: Arcane Gate , Dimension Door , Gate , Misty Step , Plane Shift , Teleportation Circle , and Word of Recall . It functions as a spell book 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 conjuration school.
• When you are hit by an attack, you can use your reaction to expend 1 charge to teleport up to 10 feet to an unoccupied space you can see. If your new position is out of range of the attack, it misses you.
