Sense Rolls

“Sense rolls” include Vision rolls,
Hearing rolls, Taste/Smell rolls, and
all rolls to use special senses such as
Scanning Sense (p. 81) and Vibration
Sense (p. 96).
To notice something using a given
sense, roll against your Perception
score, modified by the applicable
Acute Senses advantage (p. 35): Acute
Vision for Vision rolls, Acute Hearing
for Hearing rolls, and so on.
Comprehension Rolls: A successful
Sense roll means you noticed some-
thing. That is often sufficient, but in
some cases, the GM may require a
second roll to understand what you
have sensed; e.g., to realize that the
“owl hoot” you heard is really an
Indian warrior, or that the faint scent
you noticed belongs to the flower of a
man-eating plant. This roll is against
IQ for details that anyone could fig-
ure out, or against an appropriate
skill if the significance would be lost
on anyone but an expert.
Danger Sense: If you have the
Danger Sense advantage (p. 47) and
fail a Sense roll or comprehension
roll to notice something dangerous,
the GM will secretly make a
Perception roll for you. On a success,
you sense the danger anyhow!
