Requirements: Willpower 40, Psyker Talent

Simply denying a psyker access to the warp isn’t enough for you. You twist their power, redirecting it to sear their mind, punishing them for their sorcerous transgressions and unforgivable blasphemies. When you successfully use Deny the Witch (page 163) to prevent a psyker from manifesting a psychic power, that psyker suffers Wounds equal to the Warp Rating of the power they attempted to manifest.
