Secret-Keeper's Mask (Blackfingers)

Each of these full-face masks is made of stitched materials—often including humanoid skin—and has a single, bulbous eye. While wearing the mask, you gain a +1 item bonus to Deception checks to Lie and the mask doesn't impair your vision. The mask can also be activated, with an ability based on its type.

This featureless mask is made of thin, papery skin. Its single eye is a fragile bubble of venom-filled glass.
