Supernatural Awareness
The fallen are inherently attuned to the fabric of reality, and they are sensitive to energies and influences beyond the awareness of mortals. Players can make a Perception + Awareness rolls for demons to get a "feel" of the supernatural qualities of a given area. A hospital room might emanate a sense of pain and loss, imprinted by the emotions of the patients and doctors who've struggled and died within its walls. An otherwise unassuming basement might reek of the foul rituals performed there days before.
Additionally, an alert demon can sense the use of supernatural energies within her general vicinity. The fabric of reality distorts momentarily when powers are used, and the fallen can feel the ripples caused by this brief disturbance. Highly perceptive demons can draw extensive information from these ripples, gaining a sense of where the supernatural event took place.
Demons can sense supernatural energies at work within an area equal to their Faith score in miles (so a fallen with a Faith of 5 can sense energies within five miles). If a character wishes to sense the energies at work in her area, make a successful Perception + Alertness roll (difficulty 7). If the roll succeeds, your character detects the momentary distortion caused by these energies. Additional successes provide further detail.
One success: The demon knows that something has occurred (or is occurring) in the vicinity and a general idea of how powerful the effect was or is.
Two successes: The demon gains a rough idea as to the direction from which the distortion emanates.
Three successes: The demon knows without a doubt the direction from which the distortion emanates, and he has a rough idea of the distance.
Four or more successes: The demon knows pre- cisely how far away the disturbance is, and in what direction. If she knows the area well, she can work out exactly where the event took place or now occurs.
While demons can gain a sense of where an event occurs, it's impossible to tell from a distance exactly what kind of power or evocation is used. If they want more details they must investigate in person or send their agents to learn what they can.
While a demon's supernatural awareness usually functions only when the character actively searches for signs of distortion, the Storyteller can, at her discretion, make a reflexive roll on the character's behalf in the event of an exceptionally large flare of power in the vicinity.
