COOL FOR: FINE DETAIL DETECTIVES. SENSUALISTS. URBAN SCAVENGERS.
Perception wants you to be open to the world — with eyes, ears, and nose working at full capacity. It enables you to take in what others don't notice. The little wad of bills hidden away in the sugar bowl; the odor of a perp, hiding beneath the floor boards; the gulp of a suspect, after claiming they've nothing to hide.
At high levels, Perception takes in every final detail of the physical world — enough to overwhelm all but the strongest mind. However, with low levels, you are going to miss out on everything. After all, you can't arrest what you can't see, hear, or smell.
