The Grin Chorus

Your patron is the small laugh. Your patron is the smile in shadows. Your patron is Thousand Mouths and you have joined their Grin Chorus. In the plague lands of Vilthuum, a thousand prayers and curses are muttered into existence every day, and this dark Eidolon hears them all. They feed on the loathing and aggrandizement of their subjects. Thousand Mouths seeks to keep its chorus chattering and everyone loves talking about themselves. This Eidolon speaks through you when you draw from their menagerie of magic.

A Slow Descent

Beginning at 1st level, your natural destructive tendencies are amplified by your patron. At the start of each day make a DC12 + your Warlock level Wisdom saving throw. For every 3 you miss it, gain a Spiral Point. If you roll a natural 1, you cannot speak until the end of the day. Spells will not require somatic components. If you succeed on the Wisdom save, you can choose to gain a level of exhaustion to receive Spiral Points equal to your proficiency bonus.

The Thousands Know Best

Thousand Mouths has persuaded you to seek their wisdom. Starting at 6th level, spend a Spiral Point to ask a yes or no question and receive a correct answer. If you seek clarification, you must use another point to continue your inquiry, but following the first question, the truth may become up to interpretation.

Additionally, your patron has bestowed you with secrets of the universe, gain resistance to one damage type of your choice.

 

Fermata Feast

At 10th level,  your connection to Thousand Mouths is deeply rooted in your body. You can use your reaction to swallow a creature who just died, within 10 feet of you, of the same or lesser size, at CR2 or higher, to regain a spell slot.

The Coda

All pieces must come to an end

At 14th level, your transformation by the great Thousand Mouths is complete and they can now sing through you. Spend your action to make a ranged attack against a foe. It takes the form of one thousand mouths opening up from your skin shrieking at your foe. If it hits, your foe is cursed by Thousand Mouths and has disadvantage on all saving throws for 1 minute.
