The Master was able to somehow bring forth psychic abilities in certain humans after they were injected with FEV (usually the pineal gland, but also the amygdalae or medulla oblongada), but most of the experiments were failures (resulting in insanity) or used to line the corridor of revulsion. He was able to attack humans mentally, although his attacks could be repelled with proper training.

Canonically, all pyskers were wiped out with the destruction of the Cathedral in 2162, but psykers continue to pop up throughout the wasteland through the conditions stated before.Īfter being dipped in FEV vats, absorbing some other people and being connected to the LA Vault computer, the Master gained some psychic powers to an unknown extent. These abilities include, but are not limited to: control over electricity, fire and light, short and long-range telepathy, premonition and the ability to foretell future events. These strange powers have many causes: Forced Evolutionary Virus, mutations from radiation, natural mutations and centuries of seclusion are among the conditions that can foster these psionic abilities.
