Athenaean Scrolls

If you roll a double when making a successful Psychic test for the bearer, your opponent cannot attempt to resist that psychic power with a Deny the Witch test or negate it by any means. Note that the psyker will suffer Perils of the Warp on a roll of double 1 or double 6, and if slain by Perils of the Warp, the power they were trying to manifest will still automatically fail.
