The Broken Goblet of the Pristine Sea is a weapon ascension material tied to Fontaine. It sits at the lowest rarity in a three-tier set and is the green base item you burn through fastest when leveling Fontaine-era weapons. Most players hit a shortage of it long before they run low on the higher tiers.
Quick answer: Claim it by clearing the Echoes of the Deep Tides Domain in the Court of Fontaine, which opens only on Wednesday, Saturday, and Sunday, then spend 20 Original Resin to collect the drop.
Where Broken Goblet of the Pristine Sea drops
The material comes from the Echoes of the Deep Tides Domain, a Domain of Forgery located in the Court of Fontaine. You reach it by teleporting to the nearest waypoint in Fontaine and heading to the marked forging domain.
The domain runs on a fixed weekly schedule. It is only open on Wednesdays, Saturdays, and Sundays, so plan farming sessions around those days. Outside that window the domain is locked and will not award the goblet.
Higher domain tiers drop more material per run, so challenge the highest level your team can clear. The recommended party level for the first tier is 15, but the better rewards sit at the upper difficulties.
Domain requirements and Ley Line Disorder
The Echoes of the Deep Tides Domain leans heavily on Hydro. Its Ley Line Disorder grants a Hydro DMG Bonus to all party members after a character triggers a Hydro-related reaction. Bringing a Hydro unit lets you keep that buff active and clear faster.
Hydro, Pyro, Cryo, and Anemo characters all perform well here, but none of them are mandatory to finish the run. After you defeat the final wave, collect the loot using 20 Original Resin, or one Condensed Resin for the doubled payout.
Other ways to get the goblet
Domain runs are not the only path. The material also turns up at a Fontaine souvenir shop, where you can exchange currency for it without spending Resin. That route is useful when you are short a single goblet and do not want to wait for a domain day.
You can also push the goblet up the rarity ladder through alchemy. Combining three Broken Goblets plus 125 Mora crafts one Wine Goblet of the Pristine Sea, the next tier in the set.
Weapons that use Broken Goblet of the Pristine Sea
The goblet feeds a wide spread of Fontaine weapons across rarities and types. If you are leveling any of these, you will need this material in bulk.
| Weapon | Rarity | Secondary stat |
|---|---|---|
| Tidal Shadow | 4★ | ATK% |
| Ballad of the Fjords | 4★ | CRIT Rate% |
| Rightful Reward | 4★ | HP% |
| Portable Power Saw | 4★ | HP% |
| "Ultimate Overlord's Mega Magic Sword" | 4★ | Energy Recharge% |
| Cashflow Supervision | 5★ | CRIT Rate% |
| Crimson Moon's Semblance | 5★ | CRIT Rate% |
| Lumidouce Elegy | 5★ | CRIT Rate% |
Each of these pairs the goblet with one of two enemy drop materials and a forgery item, so stock up on those alongside your domain runs.
Treat the Wednesday, Saturday, and Sunday window as your only reliable bulk source, lean on Condensed Resin to halve the grind, and top off any last-minute shortfall at the Fontaine souvenir shop. That combination keeps a full weapon ascension on track without waiting an extra week for the domain to cycle back open.
