Otherworldly Patron

At 1st level, a warlock gains the Otherworldly Patron feature. The following option is available in addition to those offered in the Player's Handbook.

The Grimoire

Your patron is an unknowable mystery revealed on dusty pages in obscure libraries. You have bound yourself to a desperate life of searching for forgotten books and texts best left unread. Perhaps there is a great text that calls to you, such as the infamous Necronomicon, or perhaps the mystery of your patron will always be one more ancient tome away, forever to be veiled in arcane secret.

Being bound to such mystery changes the nature of your magic. The books you find can grant you access to powers other warlocks cannot achieve. However, some of those texts were not meant to be found by mortal readers, and your sanity may be lost among the tomes.

Expanded Spell List

The Grimoire lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Grimoire Expanded Spells

Spell Level Spells 1st comprehend languages, identify 2nd locate object, phantasmal force 3rd counterspell, major image 4th confusion, locate creature 5th hold monster, legend lore

Personal Grimoire

Starting at 1st level, you posses a spellbook in which you may inscribe warlock and wizard spells. At first level and as you gain levels, the warlock spells you learn and the spells from your expanded list are added to the book at no cost. Additionally at 1st level, the book begins with two spells from the wizard spell list written in it. If you elect to take the Pact of the Tome feature, this book may serve as your Book of Shadows.

You may inscribe wizard spells you encounter in other spellbooks or on scrolls into your spellbook for the same cost in time and materials as it would cost a wizard to do so.

At the start of each day, you may elect to study your book for one hour. If you do, you prepare a number of spells from your book equal to your intelligence bonus + your warlock level in place of your known warlock spells. For the rest of the day, intelligence is your spellcasting ability for these spells and for the cantrips you know.

While your spells are prepared in this way, any ongoing spells you have cast end when you regain spell slots by taking a short rest.

Extraplanar Athenaeum

At 6th level, you gain access to a library located in an extradimensional space.

The library is an 80' by 40' space with 20' ceilings, furnished however you choose. The furnishings cannot be removed. While in the space, time passes at one seventh its usual rate, so a week of time passes in the library while only a day passes on the material plane. While in the library you do not become tired, hungry, or thirsty. You cannot benefit from a short or long rest in the library. The library is warded from the scrying and divination of any being less powerful than a god.

As an action, you may summon a book from the library, or send a book that is in your possession to it. You may spend ten minutes performing a ritual that will transport you and any number of willing companions within 30 feet to the library, or transport all of the creatures in the library to your point departure or to a library that is well known to you.

Fruits of Research

Starting at 10th level, the Grimoire can reach across dimensions to grant you knowledge when you need it most. In place of a prepared spell, you may cast any wizard or warlock spell of a level you can cast that is written in one of the spellbooks in your Extraplanar Athenaeum. You must finish a long rest before you use this ability again.

Knowledge Unbounded

At 14th level, your research into forbidden knowledge has expanded your mind beyond the bounds of mundane sanity. Your intelligence increases by 2 and your maximum intelligence becomes 22 if it is lower than that. You gain permanent disadvantage on saves to resist illusions and madness.
