Your demonic master prefers subtlety and guile, allowing you to obscure the source of your powers. The flames of your Demonic Fire, Profane Contract, or Unholy Regeneration gifts burn the color of normal flames. In addition, when your Infernal Power gifts are in effect, your aura does not show signs of infernal taint. Anyone who examines your aura while these gifts are in effect does not detect any infernal abnormalities.
