The Framework

Some warlocks bargain with entities. Others with gods.
You bargained with existence itself.

The structure of reality is not a passive thing — it strains, tears, and repairs itself constantly. You are one of those repairs. A living correction. A consciousness partially overwritten by the fundamental laws that bind time, matter, and possibility together.

Power flows through you not as a gift, but as a side effect of being used as a stabilizing anomaly. Each time you invoke your patron, the universe borrows more of you than it returns.

Your thoughts do not move in straight lines. Your sense of self feels… optional. And somewhere, in the silent space between moments, something vast and impersonal is aware of you — not with interest, but with necessity.

4th	Banishment, Greater Invisibility
5th	Wall of Force, Hold Monster

 

Nihil Self

Starting at 1st level, as a bonus action, you may enter your Nihil Self state for up to 1 minute. You can end it early on your turn (no action required). You can use this feature a number of times equal to your Charisma modifier per long rest.

While in this state:

• Attack rolls against you are made with disadvantage.
• You cannot regain hit points.
• At the end of each of your turns, you take force damage equal to your proficiency bonus + your Charisma modifier (this damage ignores resistance and immunity).

If you drop to 0 HP while in this state:

• You fall prone and are restrained by void static.
• You begin making death saving throws as normal.
• You cannot be healed or stabilized by external means.
• An ally within 5 ft can use an action to make a Strength check against your Spell Save DC to pull you free, ending Nihil Self.

Any effect that suppresses magic ends Nihil Self.

Controlled Instability

Starting at 6th level, you can corrupt the space inbetween two creatures as an action, making them swap place. Both creatures must be within 60 ft of you. Unwilling creatures may make a Charisma saving throw against your spell save DC, negating the swap on a success. You may use this feature a number of times equal to your Charisma modifier and regain all uses after a Short or Long Rest

Nihil All

Starting at 10th level, while in Nihil Self you gain these effects:

• You have advantage on saving throws against spells.

• The area within 15 ft of you is warped. Creatures that start their turn within 15 ft of you take force damage equal to your Charisma modifier.

• Whenever a creature returns from your banishment spell after you maintained concentration for the full duration, it must make a Charisma saving throw against your spell save DC. On a failure, the creature’s hit point maximum is reduced by an amount equal to twice your warlock level + twice your Charisma modifier. It also takes an ammount of force damage equal to this reduction. This reduction lasts until the creature finishes a long rest.

Concious Glitch

Starting at 14th level, at the start of your turn in Nihil Self, you may use your reaction to revert to the state you were in at the start of your previous turn, regaining the HP you had at that time. You do not regain spell slots, pact magic slots, or class resources. Conditions affecting you are removed unless they were also affecting you the previous turn. Once you use this feature, you can’t use it again until a long rest.
