Path of the Moonshroud

They are the darkness that chokes out the light in but a moment, rending their enemies with their shifting shadows. 

Stance of Whispers

At 3rd level, you learn to be as quick and quiet as the untold things in the dark. You can use your bonus action to take the Dash, Disengage, or hide action while standing in dim light or darkness. 

In addition, you gain proficiency in stealth and sleight of hand. 

Moon's Embrace

At 3rd level, when you enter rage, you can cover your limbs in flickering shadows and use it as a natural weapon you are proficient with. You use your strength modifier for attack and damage rolls using these shadows, and deal 1d8 necrotic damage on a hit.

When you use the Attack action, you can make one additional attack with these shadows as a bonus action. If the attack succeeds, you can choose to attempt afflicting the targeted creature with the frightened status condition against a save DC equal to 8 + charisma modifier + proficiency bonus. You can do this as many times as your proficiency bonus before a long rest. 

Umbral Evasion

At 6th level, your instinctive agility lets you dodge out of the way of certain area effects and your hardiness lets you push through excruciating pain.

When you are subjected to an effect that allows you to make a Dexterity or Constitution saving throw to take only half damage, you instead take no damage if you succeed on the saving throw, and only half damage if you fail. This ability can be used as many times equal to your proficiency modifier.

Cloaked Cadaver

At 10th level, the shadows surrounding you grow more intense with your malice. The damage die of searing shadows increases to 1d10, and they score a critical hit on a roll of 19-20. In addition, you can create a burst of shadows around you as a reaction, posing disadvantage on ranged attacks. 

Darkness Bringer

At 14th level, the darkness from within you emanates with even greater force. While you're raging, you are under the effects of the shadow of moil[ spell, giving enemy creatures disadvantage on attack rolls against you.
