Hidden chests that are revealed by equipping the Sacred Staff. They aren’t hard to find if you know they exist, but I thought I’d just compile the ones I found.

The one in the Spring Highlands
This one isn’t revealed by the Sacred Staff, and it shows up once you grow the trees around it using the Sacred Drum. It’s gray and it doesn’t show up in the map, like some of the other ones, so I thought I’d include it.
