Divine Spark: Infallible Darkness

The dark nature of your power has taken root within you and has bound itself wholly to your soul. By giving yourself to your drives and ambitions, you have discovered that the most pure form of your power was within you all along, it just needed to be accepted. While the ominous nature of this gift may seem as though it bears evil energy, the truth is that this is a pliable power that may be wielded as the user sees fit, after all, the very beginning of this path began with your choice and is only strengthened by following through with those choices without wavering.

By binding the truth of your soul with the energy granted by your guide, you may now fully manifest ambient mana and you may manipulate the very shadows as being free of the chains of fate grants you the ability to change the unknown. The abilities associated with this feat describe what you may control as well as the boons granted by fully committing yourself to the path of the Onyx Legion.

***Soulbound Weapon Pact: You choose a weapon with which you have proficiency. You must have been wielding or had wielded this weapon while you gained an inspiration point in accordance to your Dark Ambition class feature. The chosen weapon must also be free of any hostile spirits or intelligence that would prevent you from sharing a fraction of your soul with it. If your weapon fits the above criteria, you may initiate your soul bond with it. While bonding, you must maintain concentration for 1 hour, after which, you will become attuned to it. The cost of this ritual is your body's inner life force, which permanently consumes your Hit Dice, disabling them forever after this ritual. After attuning, your soul will become that of a pure, shadowy energy and your generated life force (your own hit dice) creates an effigy of your soul which will act as a homing device should your soul ever be removed from your body or your body can no longer house your soul. This creates a shadow-bound phylactery. The strange energy used in this ritual causes your phylactery to possess unique capabilities that are dissimilar to that of a lich. 

First, your phylactery acts as a receptacle for your soul should your body be destroyed or killed. As long as your phylactery remains free of restrictions or wards, your soul will immediately enter it, joining with your sacrificed fraction once more. While in this state, your body crumples to dust, leaving only your possessions behind. Your body will reform within 1d6 hours as long as there are any shadows within 120 feet during that time, your body will be forged anew from the nearest shadows. Any scars or physical imperfections you once possessed will be removed, replaced with the shape of a pristine body of your original race (any defining features such as ear shape or eye color remain). Your Hp and spell slots return when your body is recreated.

Next, your weapon becomes supernaturally resistant, gaining immunity to all non-magical damage and resistance to all magic except for Radiant damage. Should your weapon be destroyed, you must immediately make a Constitution save (DC 15) and if successful, the weapon will reappear in the nearest shadow large enough to conceal it from all light. If you fail this save, your weapon is destroyed and you will be removed from the game. You will be able to reenter the game once your weapon is repaired, if it is not repaired within 1 week's time or it is incapable of being repaired, your soul disperses into the ambient energy of the world's shadows and cannot be reclaimed in any way.

In addition to your Weapon Phylactery, you also gain the ability to manipulate, and sometimes, even control the very shadows. Upon gaining this divine spark and attuning to your chosen Weapon, you will feel an intense calling to the darkness around you. From the tiniest shadow cast by a twig to the great depths of the underground, you are able to exert your will onto the darkness that is ever present in the world.

While you are wielding your Weapon Phylactery, you may manipulate the shadows and your dark energy in the following ways:

*You may teleport up to your speed as a move action as long as you end the movement in shadows or darkness. You can use this movement as a reaction against an attack you can see coming from melee or ranged with an Athletics or Perception check contested by the incoming attack's roll. If you use this reaction and fail your skill check to move, you may still move your speed by teleporting but you take damage from the triggering attack.

*You can use your bonus action to extend up to 20 cubic feet of shadows or darkness within 15 feet of you. Extended squares of shadows double in size and grant concealment if you are fully surrounded by them on all sides. The shadows remain extended for a number of rounds equal to your Constitution modifier or until radiant damage is dealt to you or cast in the area of the shadows.

*As a bonus action, you can manipulate the properties of shadows, causing them to become tangible for a moment. Any affected shadows become three dimensional structures in accordance to their original size. These shadows are tangible until the end of your next turn. You may ultimately determine the function of the shadows (Platforms, walls, sharp edges, simple items/shapes, etc.) but the strength of the material they emulate must be determined by a Constitution or Strength check made when using this power with the results as follows:

   *1-8: As sturdy as wood.  *9-16: As sturdy as stone  *17-20+: As Sturdy as hardened steel
