The Void

The Void itself is very unknown. It can be seen as a dark purple/blue mist and has taken over a whole plane of existence in the outer realms. Void magic is corrupt, but it can be manipulated to do certain magical abilities. However the void itself will always make those who take advantage of its power pay in many different ways. Luckily for you however, the void has chosen to give its gifts to you willingly - but this is not for free. The Void aims to grow and corrupt as much as possible, however it cannot leave its own realm, however you can. The Void will give you some of its maddening powers so that you can expand its influence through killing or maddening as many creatures as possible, beware however, as if you try to go against its will you will find yourself going insane. 

When creating your character consider - why did the void chose you?

The Void's Blessing

Starting at 1st level, when you reduce a hostile creature to 0 hit points, you gain temporary hit points equal to your Charisma modifier + your warlock level (minimum of 1).

Power of The Void

As a bonus action you may embed the power of the Void with your attack adding [roll]1d6[/roll] psychic damage to your attack and force your target to take a wisdom save, on a successful save they take a random short term madness effect on a failed save they take a random long term madness effect

You can preform this ability only once in substantial light, and regain in a short or long rest. In darker places you can preform this at will, however those around will also have to take a wisdom save, with an advantage for each 5 ft they are away from the target, up to 20ft, on a failed save they will take a short term madness effect - unless they are already mad or a void elf in which they already succeed on the save.

Due to the energy which this takes, you lose 3d8 psychic damage and all (sane) companions lose 1d8 psychic damage from seeing the horrors which you have unleashed.

The Void's Own Luck

Starting at 6th level, you can call on the Void to alter fate in your favor. When you make an ability check or a saving throw, you can use this feature to add a d10 to your roll. You can do so after seeing the initial roll but before any of the roll’s effects occur.

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

The Void's Resilience

Starting at 10th level, you can choose one damage type when you finish a short or long rest. You gain resistance to that damage type until you choose a different one with this feature. Damage from magical weapons or silver weapons ignores this resistance.

Plummet through the Void

Starting at 14th level, when you hit a creature with an attack, you can use this feature to instantly transport the target through the lower planes. The creature disappears and hurtles through a nightmare landscape.

At the end of your next turn, the target returns to the space it previously occupied, or the nearest unoccupied space. The target takes 10d10 + 20 psychic damage as it cripples from its maddening experience.

If the target is killed you regain 2d8 hit points as a reward from the Void.

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