Now you have a buried treasure map. Take a look. If you're not standing near the treasure, you can see the outline of the land, the ocean streaked with orange.

As you approach buried treasure, the map fills with color. In the image above, you can see that the map has been partially filled in. Most of the time, you'll find these boxes on the beach or near the shore. Though rare, you might find a box in the middle of the ocean. If this is the case, make sure you have breathing and water affinity magic on your armor so you can reach the bottom of the sea without drowning.
