Psychic nullifier (Fallout)

A psychic nullifier is a miscellaneous item in Fallout.

Gameplay
The psychic nullifier is a strange device, possibly the product of an alien technology. It blocks telepathic or psychic commands.

Uses
It is placed on the head of a psychic to disable or prevent them from using their powers. A psychic nullifier also blocks incoming telepathic attacks when worn in the Corridor of Revulsion, which is why it is required by all members of the Unity that are allowed an audience with the Master to wear when in his presence.

Locations

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