Prognosticars are especially sensitive to the fluctuations of the Warp, which allows them to detect the psychic tremors that are inherent in daemonic incursions into realspace.

Thus, a Prognosticar is capable of determining the location and severity of such an event. This skill appears similar in manner to an oracle in form, though in function it is similar to a highly specialised form of hunting instinct.
