OotD* - The Sphinx

You have made your pact with a sphinx, a creature as powerful as it is inscrutable. Unflinching guardians of divine treasures, from temples to enchanted artifacts, as well as living repositories of lore and ancient knowledge, sphinxes desire only to fulfill their divinely appointed missions. Bound eternally to a single place of stewardship, some sphinxes choose to cede fractions of power to mortals, empowering warlocks to act as their agents in the world abroad. Sphinxes mighty enough to forge such pacts include the ancient sphinx Firaleene, as well as Isperia, supreme judge of Azorius.

Roar of Censure

Starting when you choose this patron at 1st level, you can manifest your patron's prideful roar as a reaction when you take damage from a creature within 30 feet of you. The creature must make a Strength saving throw against your warlock spell save DC. On a failed save, it takes thunder damage equal to your warlock level and is knocked prone and pushed up to 30 feet directly away from you. On a success, it takes half as much damage and suffers no other effect. This effect is audible within 100 feet.

You can use this feature once and regain the use of it after finishing a short or long rest.

Knowledge of the Ancients

Also at 1st level, you are blessed with a portion of the Sphinx's eternal wisdom. You learn Sphinx and one other language of your choice. You also gain proficiency in your choice of two of the following skills: Arcana, History, Nature, or Religion.

Arcana

You gain proficiency in Arcana.

History

You gain proficiency in History.

Nature

You gain proficiency in Nature.

Religion

You gain proficiency in Religion.

Chronic Slipstream

At 6th level, the Sphinx teaches you how to step through time just ahead of others around you. When you make an initiative check, you can add a bonus to the check equal to your Charisma modifier.

Inscrutability

Beginning at 10th level, you can shield your mind and self, becoming as indiscernible as the mysterious sphinx. You are immune to any effect that would sense your emotions or read your thoughts, and you can't be targeted by any divination magic or perceived through magical scrying sensors unless you allow it. Wisdom (Insight) checks made to ascertain your intent or sincerity have disadvantage.

Glimpse of Eternity

Also at 10th level, you learn to parse portentous visions of the future in imitation of your patron. You can't be surprised.

Roar of Time

By 14th level, you can use an action to channel a small portion of the Sphinx's mastery over time and space with a reality-twisting roar. Each creature within a 30-foot cone originating from yourself that can hear you must make a Constitution saving throw against your warlock spell save DC. On a failed save, a creature takes 6d8 thunder damage, ages 2d10 years, and suffers 2 levels of exhaustion. On a success, it takes half as much damage and suffers no other effect. This action is audible out to 500 feet.

Once you use this feature, you can't do so again until you finish a long rest.

Additional Eldritch Invocations

If an eldritch invocation has a prerequisite, you must meet it to learn the invocation. You can learn the invocation at the same time that you meet its prerequisite. A level prerequisite refers to your level in this class.

 

If you pick an Additional Invocation, be sure to leave that level's choice blank in the regular Invocations feature. Likewise, if you choose regular Invocations instead, be sure to leave this feature blank.

Book of Prophecy

Prerequisite: The Sphinx patron, Pact of the Tome feature 

Your Book of Shadows serves as a powerful conduit for the divinatory powers of the Sphinx. When you cast a divination spell of 5th level or lower while your Book of Shadows is on your person, you can do so without expending a spell slot. Once you use this invocation, you can't use it again until you finish a long rest.

Fleeting Eternity

Prerequisite: 17th level, the Sphinx patron

You can expend the use of your 9th-level Mystic Arcanum to cast time stop.

Lion's Claws

Prerequisite: The Sphinx patron, Pact of the Blade feature

You can summon a pair of clawed gauntlets using your Pact of the Blade feature. While wearing these gauntlets on your hands, you can treat them as melee pact weapons that inflict 1d8 slashing damage on a hit and have the finesse property. Also, you can use Charisma instead of Strength when you make an Athletics check to attempt or contest a grapple or a shove.

Lion's Share

Prerequisite: 5th level, the Sphinx patron 

You can cast create food and water once using a warlock spell slot. You can't do so again until you finish a long rest. When you cast create food and water this way, the food is deliciously heavenly to your taste.

Pseudosphinx

Prerequisite: The Sphinx patron, Pact of the Chain feature 

While you have a cat as your familiar, it gains additional hit points equal to your warlock level. Your cat can speak any languages you can, and its Intelligence, Wisdom, and Charisma scores each become 15. When it would be reduced to 0 hit points, you can use a reaction to allow your cat to slip through time and be reduced to 1 hit point instead.

Once you take this reaction, you must finish a short or long rest before you can do so again.

Visions of Old

Prerequisite: 7th level, the Sphinx patron 

You experience the cumulative 25 percent chance of getting a random reading when casting divination when you cast the spell three or more times before finishing a long rest, instead of two or more times.
