ST: Investigate

Investigate	You follow tracks or look for clues. You learn how to start Investigating as an Exploration Action \| ▼, which differs from Seeking or Scouting. While Investigating, you may attempt an active Insight or Perception check vs a set DC, usually a Concealed roll or something set by an adventure or from a creature, and this DC may be adjusted up or down, depending on the context (such as weather, darkness, track freshness, etc). This check is made once per hour while following a single trail or for a set of clues. On a Success, you find the trail or continue to follow a trail you've already found or were following. On a failure, you lose the trail, and must wait another hour to find it again.
