The arm has the aesthetic of a spectral wraith, it flows with wisps of blues, greens, and gray. The fingers come to sharp points, almost like claws. 

You cannot un-attune yourself from Wraith's Grasp. You are bound to the death realm and when your journey is over, you will be too. While you remain alive however, the guardian of the death realm has gifted you with a spectral arm that can aid you for your limited time on the material plane.

While attuned, you gain access to the Wraith Hand cantrip. 

Notes: Character who has escaped death.
