Golden Goblet of the Pristine Sea

To obtain Golden Goblet of the Pristine Sea, you'll need to challenge the Echoes of the Deep Tides Domain located in the Court of Fontaine region.

There is a chance for you to be rewarded with Golden Goblet of the Pristine Sea by successfully challenging the Domain of Forgery: Curious Contraptions at level IV or higher. It's only open on Wednesdays, Saturdays, and Sundays. The recommended party level for the Domain of Forgery: Curious Contraptions IV is 80.

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.

When the Usurper of the sunken city played the last movement of the golden symphony, the favored musician stole the golden goblet brimming with Ichor. Shocked by the foolhardy betrayal of the God King, the musician summoned the last guards, and used the insoluble Ichor to seal the dragon beneath the tall tower, and sank into the abyss with the capital. Afterwards, this noble thief vanished silently from history, and only the "Golden Troupe" faithfully remembers his prophecy.
