Shadow Adept - Sorcerer Archetype

Flickering, wavering, dancing between the border of light and darkness, your innate magic is drawn from the dark and gloomy reflection of the Material Plane, the Shadowfell. Perhaps you traveled briefly through a shadow crossing, unknowingly bringing back with you a wisp of the starkly colorless Plane of Shadow that is now a part of you, or maybe you are just innately in tune with the nature of the Shadowfell itself. Sorcerers with this origin feel at home immersed in the darkness, finding sanctuary deep within the recesses of the world and drawing upon the great power inherent to the nature of shadows, using it in a multitude of ways.

Shield of Shadows:
Starting at 1st level, you can mold nearby shadows to obscure you from attacks. Whilst in dim light or darkness, you can use your reaction to gain Half Cover against attacks, spells and abilities that target you or allow a Dexterity saving throw to reduce the damage. Once you reach 5th level, when you use this ability you can also expend 1 sorcery point to gain Three Quarters Cover instead of Half Cover. The Shield of Shadows lasts until the beginning of your next turn.
You can use this ability a number of times equal to your Charisma modifier (minimum 1) per long rest.


Shadow Spell:
At 6th level, you can manipulate the inherent shadows of certain spells to recreate its effects.
When a creature you can see casts a spell that targets you, a creature or area you can see within 30 feet of you, you can use your reaction and expend 1 sorcery point to add that spell to the list of spells you know. This spell does not count towards the number of spells you know, is considered a sorcerer spell for you, and you retain knowledge of it for a number of rounds equal to your Charisma modifier (minimum 1). Once you cast a spell learnt in this manner, or a number of rounds passes as described above, you lose all knowledge of this spell and remove it from your list of spells known.
If this spell has a duration of concentration and you lose knowledge of it whilst concentrating on it, you must succeed on a concentration check (DC = 10 + the spells level) at the beginning of your turn to be able to maintain it.

Additionally the spell must meet the following requirements:

• The spell must be of a level that you can cast.
• The spell cannot have a casting time longer than 1 action.
• The spell cannot have an effect that specifically generates light (such as the Daylight spell), nor can it deal radiant damage.
  
• The spell cannot have a healing effect unless it is from the Necromancy school.
  
• The spell is not a spell cast from the use of this ability.

Enshrouding Gloom:
From 6th level, you gain the ability to subtly control the shadows around you. You can use a bonus action to lower the level of ambient lighting within a 60-foot radius centered on you. Areas of bright light are reduced to dim light, and areas of dim light are reduced to darkness. The lighting remains this way until the end of your next turn. 
This lighting is considered natural, and can be seen through as normal by creatures with darkvision. You cannot use this ability if you are in an area of direct sunlight or a spell that creates equivalent light (such as the daylight spell).


Shadow Double:
Starting at 14th level, whilst in dim light or darkness, as an action you can create a double of yourself woven from shadowstuff that rises out of your own shadow. The double lasts for 1 minute, or until you lose your concentration (as if concentrating on a spell). 
The double has the ability scores, AC, saving throws, and proficiencies as you, 1/2 your total hit points, but no equipment (any apparent clothing or equipment is nonfunctional).
The double can attack your enemies if given a weapon or items (since it can use anything you can), and functions in the same way as the Project Image spell, except that it only requires a bonus action to mentally command it. The double acts on your initiative count in combat, though it is a separate creature.
For the duration, you can cast spells as though you were in the double’s space (no distance limitation). Using the double as the originator of a spell counts as an action for both you and the double. Anything that causes you or the double to leave the plane you share dismisses the double.
The death of the double does not affect you.
Once you've used this ability, you cannot use it again until you complete a long rest.


Living Shadow:
From 18th level, you can infuse your body with the energies from the Shadow Weave. Whilst in dim light or darkness, you can use your action and expend 5 sorcery points to gain immunity to all damage except force, psychic or radiant for up to 1 minute or until you lose your concentration (as if concentrating on a spell). You have vulnerable to radiant damage during this time.
Whilst Living Shadow is active and you in an area of dim light or darkness, instead of moving normally you can teleport a distance up to your normal movement to an unoccupied space that you can see that is also in dim light or darkness.
You can use this ability once per long rest.
