Whisperwind Haven in Rinascita is home to three Fratelli brothers, each offering a unique challenge. Completing all of them rewards you with Advanced Supply Chests containing Astrite and other items, and unlocks a hidden achievement. This guide walks you through each task.

First Brother: Egla Town Book Challenge

Warp to Egla Town’s Resonance Beacon and head to the fountain at the town’s center. You’ll find Fratellino there—but only if the in-game time is between 6:00 and 18:00. Interact with him to start the Echo Challenge: Unfinished Book. You’ll take control of Lottie Lost Echo and must collect book pages by following a glowing golden trail. You need at least 75% accuracy to succeed; if you fall short, you can retry as many times as you like. A solid trick is to use the water fountains as landmarks to stay on track. Passing the challenge rewards you with an Advanced Supply Chest.

Second Brother: Polyphemos Windmills Flight Challenge

Warp to the Polyphemos Windmills Resonance Beacon and go to the cliff edge nearby. There you’ll meet Fratello. His challenge is a timed Flight trial: you link to a Wingray and must pass through a series of checkpoints to reach a marked destination within the limit. The flight itself guides you toward the Silver Moon Grove area. Succeeding grants you another Advanced Supply Chest.

Third Brother: Harder Book Challenge Near Silver Moon Grove

After completing the flight, you’ll land near the Silver Moon Grove Resonance Beacon. Head southwest to an open field with a book monument, where another Fratellino awaits. This is the Echo Challenge: Unfinished Book again, but with a trickier trail. The accuracy requirement is still 75% or higher, and you can retry until you get it. Completing this challenge gives you an Advanced Supply Chest and an additional 20 Astrites.

Second Brother’s Final Puzzle: Plushie Punch

Return to the Polyphemos Windmills area and head north of the Resonance Beacon to a dilapidated building. You’ll find Fratello once more. His final challenge is Echo Challenge: Plushie Punch. You transform into a Cuddle Wuddle Echo and must smash a Seamrock by pressing the button when the pointer is in the highlighted zones. Orange zones fill the progress bar more than yellow ones. If you don’t fill the bar before the timer runs out, you restart until you succeed. Beating this earns you the last Advanced Supply Chest.

With all challenges cleared, the hidden achievement tied to the three Fratelli brothers is yours.
