Shadow Thief

Some Rogues have acquired dark powers from occult sources such as the Shadowfell , the Far Realm, or from participating in dark rituals that imbued them with these powers. They have become one with darkness, a creature of the night. A rogue gifted with these strange powers is known as a Shadow Thief.

Shadow Thieves tap into the power of elemental shadow to enhance their roguish skills. They can pass through vault doors, travel between shadows, or hide from detection. Some can even transform into living shadow, able to move about and avoid obstacles unhindered.

Shadow Touched

Their connection with elemental shadow grows as the Shadow Thief gains levels. This gives them access to new abilities.

Shadow Walk
At 3rd level, you gain the ability to step from one shadow into another. You can use your Cunning Action teleport up to 60 feet to an unoccupied space you can see that is in dim light or darkness. This includes the shadow of a creature or object. You then have advantage on the first melee attack you make before the end of the turn.

Darkvision
At 3rd level, the Shadow Thief's sight has grown increasingly accustomed to the darkness. They can now see clearly as if it was daylight, in darkness of any sort, even magical darkness.

Shadow Move

As their connection to the shadow grows stronger, the Shadow Thief is able to move more easily through dark areas. They are also able to move in and out of shadow with ease.

Shadow Rush
Starting at 9th level, you can move and attack more effectively when surrounded by darkness.
When you are in an area of dim light or darkness, you can move at twice normal speed.

Shadow Meld
At 9th level, you have learned to become one with the shadows. When you are in an area of dim light or darkness, you can use your action to become Invisible. You remain Invisible until you make an Attack, Reaction, or are in an area of bright light.

Dark Touch

Once you reach 13th level, your Sneak Attacks are capable of draining the life force of your enemies to heal you.
Whenever you land a critical hit and use your Sneak Attack, you can choose to regain hit points equal to half the sneak attack damage.

Shadow Form

Starting at 17th level, you can spend a Bonus Action to magically transform yourself into a shadowy form. In this form, you have resistance to all damage except force and radiant damage, and you can move through other creatures and objects as if they were difficult terrain. Otherwise, you cannot Attack or be attacked in this form. You take 5 force damage if you end your turn inside an object.

You remain in this form for a number of rounds equal to your rogue level. It ends early if you are incapacitated, if you die, or if you dismiss it as a bonus action.
