Spring of Pure Sacred Dewdrop is a 4-star weapon ascension material in Genshin Impact, tied to a long list of Fontaine weapons that scale with HP, healing, and Bond of Life effects. It only becomes available on certain days, so timing matters if you want to level a weapon without waiting an extra week.
Quick answer: Clear the highest tier of the Echoes of the Deep Tides domain in the Court of Fontaine on a Tuesday, Friday, or Sunday, then spend 20 Original Resin to claim the drop.
Where Spring of Pure Sacred Dewdrop comes from
The material is farmed at the Echoes of the Deep Tides domain, located north of the Court of Fontaine. It belongs to the Domain of Forgery line, meaning it rewards weapon ascension materials rather than artifacts or talent books.
The drop is gated to three days of the week. On any other day, the domain still opens, but it gives a different Sacred Dewdrop tier instead. This is the same item group that includes Dross of Pure Sacred Dewdrop, which shares the same weekly schedule.
Farm Spring of Pure Sacred Dewdrop at Echoes of the Deep Tides
Step 1: Open your map and travel to the Court of Fontaine, then head north to the Echoes of the Deep Tides domain entrance. Make sure the in-game day is Tuesday, Friday, or Sunday before you commit.
Step 2: Enter the domain and select the highest difficulty your party can clear. The top tier (level III) has a recommended party level of 59, and clearing the highest level you can handle gives the best rewards.
Step 3: Build your team around the Ley Line Disorder. After a character triggers a Hydro-related reaction, the whole party gains a Hydro DMG Bonus, so a Hydro unit makes the run faster. Pyro, Cryo, and Anemo characters help but are not required.
Step 4: Finish the challenge, then claim the rewards using 20 Original Resin. Spending one Condensed Resin doubles the haul from a single clear.
You know it worked when the post-clear reward screen lists Spring of Pure Sacred Dewdrop in your pickup and the items land in your inventory under Character Development Items.
Craft Spring of Pure Sacred Dewdrop with alchemy
You can also produce the material at any alchemy crafting table by converting a higher tier down. This is handy when you over-farmed the top-tier drop and need more of the lower ones for early ascension stages.
| Output | Ingredients |
|---|---|
| Spring of Pure Sacred Dewdrop ×1 | Sublimation of Pure Sacred Dewdrop ×3 + Mora ×350 |
To do it, open the map, travel to any alchemy crafting table, pick the material you want, and confirm. The table will only let you craft if you hold enough of the required higher-tier item.
What Spring of Pure Sacred Dewdrop is used for
The material feeds into a single crafting recipe and a set of Fontaine weapon ascensions. Crafting Essence of Pure Sacred Dewdrop, the next tier up, costs three of these plus Mora.
| Use | Cost / Detail |
|---|---|
| Craft Essence of Pure Sacred Dewdrop | Spring of Pure Sacred Dewdrop ×3 + Mora ×1,075 |
| Weapon ascension | Used by 7 Fontaine weapons |
The weapons that ascend with this material span both 4-star and 5-star pulls, and most of them lean into HP scaling, healing payoff, or Bond of Life mechanics.
| Weapon | Rarity | Type focus |
|---|---|---|
| Finale of the Deep | 4-star | ATK and Bond of Life |
| Flowing Purity | 4-star | Elemental DMG Bonus |
| The Dockhand's Assistant | 4-star | HP and Elemental Mastery |
| Tome of the Eternal Flow | 5-star | HP and Charged Attack DMG |
| Splendor of Tranquil Waters | 5-star | HP and Elemental Skill DMG |
| Silvershower Heartstrings | 5-star | HP and Burst CRIT Rate |
| Symphonist of Scents | 5-star | ATK and healing buffs |
No playable character uses this item for ascension, so every copy you farm is going straight into weapon leveling or into crafting the next tier. If you are planning around a Fontaine support or healer weapon, line up your domain runs with the Tuesday, Friday, and Sunday window and bank the surplus through the Parametric Transformer on off days.
