adventurer may use his stealth ability only if he has adequate cover (i.e., space in which to
conceal or obscure himself) in the area he wishes to traverse, he is appropriately clad (e.g.,
not in plate armor or luminescent clothing), and he is not currently under observation by the
being(s) from whom he is attempting to conceal his presence. The GM will roll percentile dice
to determine if a character is able to use his stealth ability successfully. The GM only makes
such a check if there is a reasonable possibility that the character could be detected. The GM
makes one check each time the character attempts one continuous action, or each time an
unexpected change of condition has a significant effect upon the character's chance of
remaining hidden (e.g., one of the beings under surveillance heads for a room which happens
to be through the doorway in which the .character is hidden). The GM may modify the success
percentage. A character's base chance of using his stealth ability is ([3 x Agility] + [5 x
Rank])%. The greatest Perception value of the beings who may be able to discover the
character using the stealth ability is subtracted if those beings are unaware of the character's
presence, or three times that Perception value if they are. If the GM's roll is equal to or less
than the success percentage, the character is undetected. If the roll is between the success
percentage and that percentage plus the character's Agility, he has made a slight noise or
given a being a glimpse of himself, and may be (at the discretion of the GM) discovered. If the
roll is greater than or equal to the success percentage plus the character's Agility, he has
been discovered.
