Shadowfell Thief

You are a myth. A rumor. A ghost. Your presence rarely goes detected. The only trace you leave is the whisk of a crossbow bolt fired from a location unknown. Even those close to you may find it difficult to perceive you in the shadows as this is where you spent most of your life

Clinging Shadows

When you choose this archetype at 3rd level, you are able to hide in dim light or darkness even if you are only lightly obscured. Creatures have disadvantage on Wisdom (Perception) checks against you, while you are hidden in dim light or darkness.

Shadow Robes

Starting at 6th level, at will you call on the shadows drawing them in covering your form so completely. You gain expertise in stealth and you now have a passive stealth. It is 10 + your stealth modifier.

Shadow Touch

Starting at 3rd level, you can use the bonus action to reach through the Shadowfell and physically touch any object in shadow, to make a Sleight of Hand check, use your thieves’ tools to disarm a trap or open a lock, or take the [Tooltip Not Found] action.

Shadowfell Sniper

Beginning at 9th level, whenever you make a ranged attack from hiding, you no longer give away your location.

Shadowfell Vision

By 13th level, you have lived in the shadows so long your eyes have adapted. You have gained Darkvision both magical and non up to 120ft.

Shadow Melt

Starting at 17th level, you can take on a shadowy form as a bonus action. In this form, you have resistance to all damage except force and radiant, and you can move through other creatures and objects as if they were difficult terrain. You take 5 force damage if you end your turn inside an object.

You can remain in this form for up to 10 minutes. It ends early if you are incapacitated, if you die, or if you dismiss it as a bonus action. You regain use of this feature when you complete a short or long rest.
