Umbrakin Archetype

This archetype reaches into the black to touch a power beyond this world, and in doing so discovers more than just a place to hide. Everywhere shadows fall, the Umbrakin see extensions of their bodies, and wellsprings of power.

Shade Traversal

Starting at 3rd Level, you can link shadows together through physical space, and use them to step in and out of the world at will. Use a Bonus Action to teleport into any space under dim light or darkness you can see within 30ft of you. This ability costs no movement and does not provoke opportunity attacks. The range of this ability extends to 60ft at 9th Level, and to 120ft at 17th Level.

Shadowcrawler

At 9th Level, you gain access to the Spider Climb ability across any surface covered by dim light or darkness. This ability is innate and does not require Actions or Bonus Actions to activate. However, the ability will end the moment light is shone into your space.

Black Omen

At 13th Level when in dim light or darkness, any enemy within 30ft who cannot see you is under the effect of the Bane spell.

Umbra Betrayal

At 17th Level, the shadows themselves become yours to puppet against their casters. You can use an attack roll on your turn to animate a shadow doppelganger of any target you can see to attack them. The shadow can only attempt to attack once, but rolls with advantage and with your weapon attack bonus, It will also deal your Sneak Attack damage if it hits (the damage type is always Necrotic, immunities and resistances apply).
