Nebulous Walker (5e Subclass)
From D&D Wiki
A Nebulous Walker is a rogue who uses the dark not only to hide but merge with it.
Blend in with the Shadows
At 3rd level, you can use your bonus action to hide in the shadows without the need of a Stealth check. This grants you invisibility as long as you do not attack any creature. In addition, you can use your cunning action to teleport to an unoccupied space, that you can see, within 60 feet. You must wait 1 minute (10 rounds) before using this ability again. This decreases to 1/2 minute (5 rounds) at 9th level, 1/4 minute (2 rounds) at 13th level, and at 17th level you can do this anytime.
At 9th level, as an action, you can create a copy of yourself as a shadow which moves independently until destroyed but obeys your orders (bonus action). The Shadow has 10hp and 10 AC + your proficiency bonus. The shadow cannot attack but can perform actions such as Restrain, Stun, Blind or Frighten a creature. The Save DC against this effects is equal to 8 + your charisma modifier + your proficiency bonus. It may act as an unseen servant you can sense through. You can use this ability three times per long rest.
Manipulate the Shadows
From 13th level you may create a shadow of any form which can performs one of this tasks:
-You can stow one object the shadow is holding in a container worn or carried by another creature.
-You can retrieve an object in a container worn or carried by another creature.
-You can use thieves’ tools to pick locks and disarm traps at range.
-You can hold and use some other object that you would normally be able to use single-handed.
You can perform one of these tasks without being noticed by a creature if you succeed on a Dexterity (Sleight of Hand) check contested by the creature’s Wisdom (Perception) check.
Creator of Shadows
By level 17th you have become part of the shadows; once per short or long rest, as an action, you can create a dark fog which heavily obscures an area up to 120 feet with magical darkness for 10 minutes removable only by a spell of 6th level or higher or a wind of at least 30 miles per hour. It doesn't impose disadvange you and your allies. Your base speed in this shadow is doubled and the noise you make is reduced. You can now see in magical darkness and suffer no disadvantage on perception from dim light.
