Whenever a demon is subjected to an effect that might reveal
her to be a supernatural being, she may attempt to “spoof” the
effect, fooling it into thinking she’s an ordinary human. A
demon cannot spoof in demonic form, for obvious reasons.
The demon does not have to be aware of the effect to spoof it;
spoofing happens reflexively. The demon does not necessarily
know where the incoming detection attempt is coming from.
Spoofing doesn’t affect any power or effect that doesn’t
explicitly detect whether a target is human or supernatural,
nor does it inhibit any effects other than that detection. It
also doesn’t replace a demon’s ability to contest the effect. For
example, if a human psychic tries to read a demon’s aura, the
demon can spoof the psychic’s ability to detect that she isn’t
human, but not his ability to read her emotional state. She
might, however, get a contested roll against the power.
Spoofing does work against effects that would detect the
demon as supernatural by implication. For example, if a mage
cast a spell that lets him detect every human mind in a 20-yard
radius, a demon could spoof the effect since not registering as a
human is a dead giveaway that she’s a supernatural entity.
Dice Pool: Cover
Dramatic Failure: Not only does the demon fail to spoof the
effect, anyone observing becomes aware that she’s not human
even if the effect would only impart that information to one
person. Knowing that she’s not human does not specifically tell
an observer that she is a demon unless they would have another
way of knowing or recognizing that information.
Failure: The effect functions normally.
Success: The effect is spoofed. It registers the demon as an
ordinary human. Further readings by the same effect during the
same scene continue to read the demon as a normal human.
Exceptional Success: As a normal success, but any uses of
the same effect by the same character for the rest of the story
register the demon as human.
