Nowhales
Surreal, intelligent whale-like beings who inhabit The Nowhere, and may help the lost find a way home. They also, very rarely, act within existence by being the patrons of warlock.
Nowhales as Warlock Patrons
Your patron is a surreal entity native to The Nowhere resembling a whale, if a whale were eternal, inscrutable, and sat astride the line between Being and Non-being. For reasons of its own, it has contacted and bound you into its service, that it might act among the planes of Being. Your pact with a Nowhale allows you to experience and control the bizarre ontological properties of The Nowhere.
Expanded Spell List: The Nowhale 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.
1st Level: Absorb Elements, False Life
2nd Level: Blindness/Deafness, Rope Trick
3rd Level: Blink, Nondetection
4th Level: Greater Invisibility, Death Ward
5th Level: Teleportation Circle, Mislead
Bonus Cantrips: At 1st level, you learn the Spare the Dying and Resistance cantrips. They count as warlock cantrips for you, but they don't count against your number of cantrips known.
Embody Nothingness: At 1st level, you gain the ability, as an action on your turn, to manifest a bit of the nothingness of The Nowhere in your body, perhaps causing attacks to go through you as if nothing was there. Add your proficiency bonus to your Armor Class for 1 hour. You cannot use this ability again until you finish a long rest.
Negation: Starting at 6th level, you become more like The Nowhere, able to bring things into non-existence. As an action on your turn, you can either end one spell or magical effect on yourself a creature you touch, or, as a reaction, cause one attack that hit you to miss. You regain this ability after completing a short or long rest.
Going Nowhere: At 10th level, your non-existence progresses, as you gain the ability to briefly enter The Nowhere...and return where you wish. As an action, you step into The Nowhere for an instant, re-emerging anywhere you choose within 1000 ft. of your starting point. You cannot do this again until you finish a long rest.
The Being of Non-being: At 14th level, your mastery over being and non-being is complete. As an action on your turn, you may cease to exist for one round, during which you cannot be sense anything or be sensed, cannot affect anything or be affected by it, and cannot move. When your next turn would start, you re-appear as if newly esisting: you have your maximum hit points and no conditions. You cannot use this ability again until you finish a long rest.
