The Flow Matches are one of the more rare artifacts a traveler may find on a journey.
The first recorded instances of the Matches showed a distinct reaction when close to running water. This feature made them invaluable in searching for hidden water sources.
Since the first records, travelers have reported coming across Flow Matches that react to wind or electricity. Scholars have predicted the existence of Matches that react to other kinds of flow as well, but this has yet to be proven in the field.
