Book of infinite wisdom

You summon a minimum 100 page to maximum 10,000 book, of anything you wish to have all knowledge about, however you may not stop reading the book after you start, and as soon as you re-close the book the pages shrivel and decompose, leaving you with just it's cover. 

Each turn you can play at disadvantage, and every bonus action is stripped away until the book is finished, to progress the book, you roll a 1D10 + intelligence or wisdom modifier to progress that many pages through the book. Any effects of a short rest are gained at a quarter, and a long rest being halved, weather that be spell slot gain, HP regain, etc. 

however the limits of the book are infinite, weather you want to be proficient in a Armor or weapon, or just gain 1 extra proficiency (your DM will make your proficiency gain cap from the book. )

AT HIGHER LEVELS: level 5 - you can have 2 books at once gaining 2x the knowledge with the same disadvantages
