Reader of the Books of Study and Prophecy

 Every long rest, you can choose a sourcebook that either the DM or a player has to have access to. You cannot choose an Adventure book, and if you choose a book with creature stat blocks in it, you choose a creature type. You cannot only look at creatures with that creature type. When you are reading the book, you have disadvantage on all Strength, Dexterity and Charisma checks and Saving Throws, all attack rolls against you have advantage and time doesn’t pause while you read the book. In combat, you have to use a bonus action to pull out the book at the end of your turn.
