Chapter of an Ancient Chord

To obtain Chapter of an Ancient Chord, you'll need to challenge the Echoes of the Deep Tides Domain located in the Court of Fontaine region.

You will be rewarded with Chapter of an Ancient Chord by successfully challenging the Domain of Forgery: Robotic Ruse at level II or higher. It's only open on Mondays, Thursdays, and Sundays. The recommended party level for the Domain of Forgery: Robotic Ruse II is 39, but it's always best to challenge the highest level Domain for better rewards.

It's recommended to have Hydro, Pyro, Cryo, and Anemo characters in your party, but they are not required to complete the challenge. The Domain features the following Ley Line Disorder: After a character triggers Hydro-related Reactions, all party members will be granted a Hydro DMG Bonus. As such, place Hydro characters in the party to defeat your opponents more effectively.

After challenging the Domain, collect rewards using 20 Resin. You can also receive double the rewards by spending one Condensed Resin.

The Echoes of the Deep Tides is located in the Court of Fontaine. Refer to the image below for its exact location.

Legends say that the survivors of that ancient dynasty once cast a harp out of black iron to commemorate and mourn. A harp cast of black iron cannot be played. To mourn that ancient dynasty that was once so proud of its golden music, those remaining forged this heavy instrument and its yet weightier silence. But no matter what, the black iron harp remained as silent as that lost era.
