Magic Items

Wondrous item, very rare (requires attunement by a wizard)
While you are holding this leather-bound book, you can use it as a spellcasting focus for your wizard spells, and you gain a bonus to spell attack rolls and to the saving throw DCs of your wizard spells. The bonus is determined by the book’s rarity.
You can use this book as a spellbook. In addition, when you use your Arcane Recovery feature, you can increase the number of spell slot levels you regain by 1. This item is found in Tasha’s Cauldron of Everything.
This book holds all of the archfey Ananeira’s research notes about the cosmos. The pages are black, and whatever is written on it shines like stars. On its cover is a raw moonstone crystal that shines when the light hits it.
Holding it makes you more aware of your surroundings and place in the universe, and among the stars. It provides a +2 to your Initiative bonus.
