The Void

You have made a pact with the vast darkness that surrounds the realm with ever-creeping tendrils that reach into all places void of light and life.  While not evil, the darkness seeks to consume all.  It has no emotion or hatred for life, but only wishes to creep into all corners of the universe and bring the universe to an end if only to reset life, cleanse all corruption, and return the universe to an inert state.  It employs the assistance of those who share the wish to lay the world to rest.  The pact made is not with a physical being, but the endless void that surrounds the realm.  It grants to power of nothingness and senselessness.

Senseless

When a creature other than you ends it's turn under any of your effects that removes any one of it's senses, roll a D6. The number on the D6 correlates to another sense it loses shown by the Senseless table. This effect continually stacks so long as it is affected by the feature. Each effect is removed individually in the order they were applied every round the creature is not affected by one of your effects that applies this.

If a duplicate is rolled, the creature does not gain any additional effects.

Senseless

d6	Effect
1	The creature's sight dims and is considered blinded.
2	The creature's ears fill with a ringing and it is considered deafened.
3	The creature's mouth makes no sound as if screaming into the void and is considered silenced.
4	The creature's sense of smell fails them and they have disadvantage on perception checks using sense of smell.
5	The creature's body feels numb and has disadvantage on saves from being disarmed or displaced.
6	Nothing additional happens to the creature.

 

Lightless

The void follows you as you gain the ability to beckon others into it's depths.  You gain the ability to cast darkness an amount of times equal to your Charisma modifier.  This resets on a long rest.  Once you gain access to this feature, you always have darkness prepared, and it doesn't count against the number of spells you can prepare each day.

Lifeless

The cold tendrils of the void reach into the essence of life to stop new life from sprouting.  As it reaches further into the world of the living, it's grasp only holds stronger than before.

While a creature other than you is under one of your effects that removes any one of it's senses, it is unable to recover health points.  Your darkness spell is also considered difficult terrain.

This includes effects such as an area of effect left from a feature and the effects of a single target feature.

End

The Void hungers to end all life and will not stop until it is satiated.

Once per turn, choose an enemy that is under one of your effects that removes one of it's senses.  Lower one of it's ability scores of your choice by 1 point.  This effect last for 1 hour after a creature is no longer affected by you.  This can stack to -5 in total to the ability scores of a creature and cannot reduce a stat below 1.

This increases to 2 distinct targets at 17th level and 3 distinct targets at 20th level.
