The Divine Tome

“I cannot combine some characters . . . which the divine Library has not foreseen and which in one of its secret tongues do not contain a terrible meaning. No one can articulate a syllable which is not filled with tenderness and fear, which is not, in one of these languages, the powerful name of a god." 

- Jorge Luis Borges

You have been made a Librarian of the Divine Tome, a mystical book containing all the writings that have been and can be conceived.  The Omnibook's goals may be unfathomable, but its servants are mighty champions of knowledge and truth.  Preserving, expanding and disseminating knowledge from the Library is the life's work of its Librarians.  Similarly, people and cultures that would destroy or hinder the growth of knowledge must be changed or stopped.  The Tome has taken many forms throughout the eons: a book with infinitely thin pages, a library that is a sphere with an undetermined diameter,  a single scroll that rewrites itself to be utterly new each time eyes fall upon it.

Font of Knowledge

Starting at 1st level, you may as a bonus action implore the Divine Tome for knowledge about a creature you can see.  Make a Charisma check (DC equals the creatures Challenge Rating rounded up), on a success you know any and all immunities, resistances and vulnerabilities of the target.  You may use this feature once per long rest.

Well Read

Starting at 6th level, your patron's vast stores of knowledge slowly seep into your mind. When you make an Intelligence check or a saving throw, you can use this feature to add your Charisma modifier to your roll.

Torrent of Knowledge

Starting at level 6 you can as a reaction cause a massive amount of information to flood the mind of a creature you can see.  The creature must make a Intelligence saving throw against your warlock spell save DC.  On a failed save the creature has disadvantage on its next attack and on any Intelligence or Wisdom saving throws until the start of its next turn.  On a successful save, the creature only has disadvantage on its next attack.

Foreknowledge

At 10th level you can be blessed with the Divine Tome's knowledge of the future.  As an action you may cast divination without using material components or expending a warlock spell slot.  You cannot use this feature again until you have completed a long rest.

Written by the Victors

Starting at 14th level, your patron has gifted you knowledge of arcane secrets.  You can as a bonus action cast one of the following without expending a warlock spell slot: Crown of Stars, Power Word Pain or Regenerate (without material components).  You must finish a long rest before using this feature again.
