This last stat is an enigmatic one, and may influence play in a variety of ways. It is a rough measure of a characters level of subconscious awareness of the Zone. Some people are simply a bit more in touch with the things not seen than others. Call it psychic awareness if you want, but understand that the character is not always cognizant of such things.
