Devouring Void

Through some event in your bloodline's past, a strange force became connected to it. Be it some nightmarish entity from the Far Realm or perhaps somewhere even further beyond, has found itself intertwined with you. With its insatiable hunger now pulsing through you and shaping your bodily functions to suit its own curious tastes.

Nightmarish Metabolism

Through the endless void that now resides within you, you can now consume near any non-magical material and gain sustenance, destroying it in the process. 

On your turn, as a bonus action you can choose to eat an object with this ability. When you do so, you gain 1d4+your constitution modifier in temporary hit points. You may use this feature a number of times equal to your proficiency bonus per long rest. 

When you reach second level in this class as part of the same ability you may also regain a sorcery point. 

The temporary hit points gained through this ability increase by 1d4 at levels 6, 14, and 18. To 2d4, 3d4, and 4d4 respectively. In addition to this, 

You know the Thaumaturgy cantrip.

Arcane Absorption

Through the Void-space inside, you may store magical items through consumption

As an action you may consume one magical item up to a number equal to your proficiency bonus. Items stored this way can be attuned to in one minute. Upon the DM’s discretion* you may manifest the effects of attuned magic items without removing them from the void. You may remove items stored this way as an object interaction.

*Daren’s instant fortress and the immovable rod are examples of items that might NOT work.

While a magic item is consumed in this way It cannot be removed from your person against your will

Consuming Cravings

Upon gaining this feature, you learn Counterspell and Dispel Magic if you don’t already know them.

When you successfully counter a spell with Counter Spell, or dispel an effect with Dispel Magic, you may spend a sorcery point to store the spell’s energy within you.

If it is of a spell level which you are able to cast, you may cast it as if it were a sorcerer spell, at the level it was cast.

A spell stored this way lasts until used, countering or dispelling a new effect, being knocked unconscious or upon finishing a long rest. 

Insatiable Appetite

Your insatiable hunger allows you to convert the energy you create from matter itself into bodily manifestations. 

When you use your Nightmarish metabolism feature you may choose one of the following effects

Wings of the Void - you gain a flying speed of 40ft

Yearning Hunger - your walking speed is doubled

Eldritch Abomination - Choose an ability score, ability checks and saving throws of the chosen score are made at advantage

Gift of the Crushing Depths - You can breathe underwater and gain a swimming speed equal to your walking speed.

Abyssal Hide - Your AC increases by 2

This Effect persists until you finish a short or long rest, or use this feature again
