Base Class: Warlock
Nobody knows just what the mask is or where it came from. Indeed, how you got it is a puzzle that mystifies even you. What you do know is that the mask grants you powers you could never even imagine
Respiratory Technique
At 10th level, the Mask is able to filter any air that you breathe. While wearing the Mask, you gain immunity to all poison and disease
Thought Shield
The mask shields the mind. Starting at 14th level, your thoughts can’t be read by telepathy or other means unless you allow it. You also have resistance to psychic damage, and whenever a creature deals psychic damage to you, that creature takes the same amount of damage that you do.
Sight of the Eyeless
You can see normally in darkness, both magical and nonmagical, to a distance of 120 feet.
Silence of the Veil
The mask seals the wearer's lips together so no sound may be created. The wearer is now unable to speak. The mask also bolsters telepathic ability to allow the wearer to communicate with any being within 300 feet as long as they know a common language. The mask doesn't affect any spells requiring Verbal components, and the wearer is still affected by the Silence spell
