Knight of Necroz

You have been chosen as the mighty knight of the god of life and death, Necroz. You gain resistance to necrotic damage and you have access to the spell Disguise Self. You can cast disguise self to  shift forms from your usual form, into your Taken Form. When in your  taken form your skin turns dark grey and prismatic crystals begin grow on your face like a tattoo and begin glow, and your hands grow black crystals on them and a crystal “hat” forms on your head, and your clothes harden into black crystals. This transformation is purely cosmetic.
