What is the use of the Flute of Echoes in the remake of Dragon Quest 3
The function of the Echo Flute is to let you detect whether there are orbs nearby. It functions similarly to the Monster Tamer's "Animal Sense" skill, telling you when you're near one of the many six orbs. That said, once you collect all the orbs, the Echo Flute is effectively useless.
However, there is one orb that the Echo Flute cannot detect, and that is the yellow orb. The yellow orb does not have a fixed position in the world like other orbs, but is constantly moving. This is hinted at by a person in Lansong Temple. This means you'll have to find the Yellow Orb entirely on your own, and won't be able to rely on the Echoing Flute.
So try to find the Echo Flute as early as possible so you can really take advantage of its power. If you've collected all the orbs, at least you've got some cool new items to play with.
