Teleport Trace
Source
Galaxy Exploration Manual pg. 23
As a reaction when you observe a creature casting a spell or using a supernatural ability with the teleportation descriptor (such as dimension door), you attempt a Survival check whose DC equals 10 + 1-1/2 the creature’s CR. If you succeed, you learn the creature’s destination. This knowledge is precise if the creature traveled to a location within 2,000 feet of you or traveled to a location that’s familiar to you. For a distant location you’ve never visited or studied, you sense the creature’s general coordinates, narrowing down its destination to a town or 5-mile-radius region, but not its exact location.
