Among the Mysteries you can solve in , is among the trickiest to figure out at first. This optional side quest rewards you with a powerful combat upgrade if you manage to complete it.
However, the instructions for this Mystery are somewhat vague, making it harder to finish than you may expect when you start it.
Similar to the Mystery in , takes place in the Sukhothai region. Unlike many of the other side quests in this location, you don't have to worry about encountering any enemies during this Mystery.
That being said, you do have to explore more locations than you may expect, which can easily get you turned around if you aren't familiar with the Sukhothai map.
You start the Mystery in Sukhothai Village, the first area you explore when you arrive in the region. From where you fast travel into this location, head down the stairs next to the NPC fishing to wade into the water that occupies the settlement.
