Shadow Hand Initiate
Rogues who adopt the ways of the Shadow Hand are formidable foes. Disappearing seemingly at will and wielding supernatural powers to manipulate shadows around them, they make perfect spies when the task is to difficult for a common scoundrel. The Shadow Hand discipline teaches the arts of stealth, deception, and ambush. Its maneuvers allow a warrior to take on a shadowy aspect and channel dark energies with a mere thought.
Cloak of Shadows
As you focus your inner connection to the shadow realm, you generate flowing specters that swirl around you in a haunting manner, your own shadow joining their wicked dance.
Starting when you adopt this path at 3rd level, you gain resistance to Cold and Necrotic damage. Furthermore, while you are in dim light or darkness, you may add your Charisma modifier as a bonus on all Stealth (Dexterity) checks.
Child of Shadow
Shadows are your family and darkness is your friend, you feel most welcome in its soft and familiar embrace.
Starting at 3rd level, you gain Darkvision out to a range of 60 feet. If you already have darkvision from another source, its range is increased by 30 feet. Also, while you are in dim light or darkness, the reach of your melee weapon attacks is increased by 5 feet, as your shadow stretches out and lunges on your behalf.
Dance of the Spider
Black, shadowy energy covers your hands and feet, allowing you to scuttle across the walls like a lurking spider.
Starting at 9th level, as long as you are in dim light or darkness, you can cast Spider climb at will, targeting only yourself and requiring no components.
Shadow Stride
You slide through the dark like a bird of prey, emerging only to strike down your foe before sliding back into shadow’s welcoming embrace
Starting at 13th level, while in darkness, you are invisible to any creature that relies on darkvision to see you in that darkness. Furthermore, while in dim light or darkness, you may substitute any part of your movement for a teleportation of the equivalent distance.
When teleporting in this way, both your starting and final location must be in dim light or darkness.
Obscuring Shadow Veil
You cloak yourself in a swirling nimbus of shadow energy. These shadows spin and lash out, preventing any creature near you from being able to anticipate your attacks.
Starting from 17th level, you may use a bonus to cast Greater Invisibility as a 4th level spell, requiring no components. Once you use this feature, you can't use it again until you finish a short or long rest.
Additionally, you may cast Mirror image as a bonus action, requiring no components. Whenever an opponent within your reach hits one of your duplicates that are summoned by this class feature, you may immediately use a reaction to make a melee weapon weapon attack against them. This attack has advantage. Once you use this ability, you can't use it again until you finish a short or long rest.
