The Shadow

Tales of aberrations have been passed on generation to generation for centuries. Tales of men made of darkness that spread death and dread across the lands they haunt. For many, these are tales of legend, but for those very few that know the truth, they know the tales are not myth at all. This is the stories of the Shadows. Shadow rogues have and uncertain origin. Whether blessed or cursed by beings of great power, left to dwell too long close to the lower planes of existence, one thing is for certain, they find their home where no light shines. This order is one of the thieves' guild most well guarded secrets. Inexplicable murders and feelings of dread might all be the work a Shadow. 

Umbral Vision

Starting at 3rd level, your eyes are adapted to tenebrosity. You can see normally in darkness, both magical and nonmagical, to a distance of 90 feet. 

Shadow Strike

At the 3rd level, you gain the ability to step into the shadows. As a bonus action you can teleport up to 30 feet to an unoccupied space you can see that is in dim light or darkness. You then have the advantage on the first melee attack you make before the end of your turn. You can use this ability once plus the times equal to your charisma modifier before needing to take a short or long rest. 

Dreadful Aspect

Starting at 9th level, your presences terrifies even the bravest. As an action you can make a charisma (Intimidation) check contested by a creature's wisdom (insight) check. If you succeed and the creature is hostile to you, it becomes frightened of you, terrified that you will strike out of any shadows. This effect applies even if you are not within line of sight, in which case the creature can still move. This effect last 1 minute, or until you and the target are more than 120 feet apart, or until you fall unconscious. If you succeed on the check and the creature isn't hostile to you, it is charmed by you for 1 minute. While charmed, it will try its utmost to satisfy your request, not wanting to incur your wrath. This effect ends immediately if you are your companions do anything harmful. 

Dark Absorption

By 13th level, you have learned to temporarily to become a shadow yourself. When you use your uncanny dodge feature, you can choose, once per short rest, instead of halving the incoming damage, to reduce it to 0 and make a single weapon attack against that foe as part of the same reaction. 

One with the Shadows

When you reach 17th level, you have become one with the shadows. While you are standing in dim light or in darkness you become invisible at will (no action required).
