Perception
First and foremost, the Perception skill affects how much information your character is able to gather from the surroundings. Watching or searching an area, room, object or being can reveal important features that you can use to your advantage.
It is also possible to SEARCH for characters, depending upon your Perception skill versus the Stalking and Hiding skill of the concealed individuals. The Perception skill is automatically factored in if someone tries to hide in the room from you or stalk you. Additionally, the Perception skill assists in spotting players attempting to move stealthily in and out of the area.
The Perception skill allows for greater success in foraging (FORAGE), spotting traps (DISARM), and spotting characters that may attempt to STEAL from you.
In combat, the Perception skill provides a bonus to strike at an AIMed body location on a specified target. This skill also provides an attack strength (AS) bonus for ranged attacks and a defense strength (DS) bonus for users of missile weapons.
