A strange device, constructed from an odd technology.

A psychic nullifier is a strange device, possibly the product of an alien technology, that blocks incoming and outgoing telepathic or psychic commands.[1]


It is placed on the head of a psyker to disable or prevent them from using their powers. A psychic nullifier also blocks incoming telepathic attacks when worn by a non-psykers, such as those frequently experienced in the Corridor of Revulsion, which is why it is required by all members of the Unity that are allowed audience with the Master to wear when in his presence.[2]


  • Cathedral: Gideon, Lucy, Wiggum, and Moore each have a psychic nullifier. The Vault Dweller can persuade Gideon to give him his psychic nullifier. They all can be obtained either through theft or killing.

    Vicious: "{209}{}{You cannot be serious. In fact, you must be lying.}"
    The Vault Dweller: "{211}{}{I'm not. The Lieutenant could not trust this message to the usual method. I have to see the Master right now! There is no time to waste!}"
    Vicious: "{212}{}{Then use the door, and beware the Corridor. I assume that you have your protection in place?}"
    The Vault Dweller: "{214}{}{No, not really. Should I?}"
    Vicious: "{215}{}{Of course! You cannot hope to pass the Corridor without it. What did you do with your nullifier!}"
