Investigation is the art of analyzing evidence, piecing together clues, solving mysteries, and making logical deductions from groups of facts. Investigation differs from Perception in that it is the conscious search for clues or pieces of a puzzle.
Use Investigation to draw conclusions from assorted details. For example, Investigation could be used to determine the likely sequence of events at a crime scene, determine a possible social connection between two people, or deduce how an enemy made their escape. Investigation is a great way to provide clues to players, especially when the subject matter is something their character might know well but the player does not.
Example (optional) specializations include Evidence Analysis, Logical Deductions, Physical Investigation, Physical Tracking.
