While calls of mysterious power crowd the multiple planes of existence, there are those who, while in the process of seeking this power, look beyond those competing voices. Those who persist in this hunt find the impenetrable void, where nothing lives, no one goes, and nothing returns.  While other patrons speak directly to those who beseech their power, the void is ever silent, causing many to go insane with the unbearable emptiness of their own existence. Those who survive, find that the void speaks to them through their own thoughts and intuition, and within this emptiness the warlock is able to find a part of themselves that controls this dark void.

Shadows of the Void

Starting at 1st level, the touch of the void creates shadows around you that dims the light. In a 5-foot radius around you, bright light becomes dim light, and dim light becomes darkness. Creatures with darkvision can't see you while in darkness unless an effect specifies that it can. You are able to see up to 10 feet around you as if it was in bright light regardless of the current light level. 

Void Cloak

At 6th level, as an action, you wrap yourself in a cloak of void energy. While you concentrate on this feature for up to 10 minutes, you are not considered a valid target for any attack or spell. You are able to speak and interact with objects as normal, and can still be affected by attacks or spells that have an area of effect.

If you make an attack, cast a spell, or use an action that is hostile towards another creature, the cloak ends immediately.

Once you use this feature, you can't use it again until you finish a short or long rest.

Empty Vessel

When reaching 10th level, the small piece of the void within you allows you to hold a spell without worry of losing concentration. When you cast a spell that requires concentration, you may use this feature to enhance that spell. While concentrating on this spell, you automatically succeed Concentration checks to maintain concentration after taking damage from any source.

You can use this feature once. You must finish a long rest before you can do so again.

Infinite Darkness

At 14th level, you have carved your own space in the void that you can summon to your aid. When you hit a creature with an attack, you can use your bonus action to force it to make a Wisdom saving throw against your warlock spell save DC. On a failed save, they are blinded and deafened for 1 minute. At the end of each of the creatures turns, it takes 1d10 psychic damage for each turn it has been blinded. A creature can reroll the saving throw at the end of each of its turns after taking psychic damage. On a successful save, the effect ends.

When using this feature, you must concentrate on it as if you had cast a spell that requires concentration.
