Investigation is a Non-Combat Activity that focuses a character’s Perception onto an object, area, or scene/interaction in order to discover something about it. It relies on their other skills for context and is NEVER passive, and requires Concentration for more than a round of Time. Characters can develop these types of actions as Accomplished Activity.
This activity does not trigger anything. Generally it trades time for safety, and requires at least 30 second to a minute minimum to to complete fully.
The Observant trait can improve the chances and outcomes of good investigation.
