Exploring the Hydro nation of Fontaine in Genshin Impact offers players an incredible opportunity to gather high-tier rewards by unlocking the ancient Shrines of Depths. Scattered across both the vertical surface cliffs and the deeply layered underwater trenches, these structures contain Luxurious Chests filled with valuable Primogems and upgrade materials. To open these vaults efficiently, planning a streamlined route saves significant time and minimizes backtracking through complex aquatic zones.

Securing Your Keys Before Departure

Before plotting your map course across the regional territories, travelers must acquire the corresponding Hydro keys required to break the ancient seals. These keys are earned by offering Hydro Sigils to the Fountain of Lucine situated outside the Opera Epiclese. Additionally, upgrading the Statues of the Seven across Fontaine will reward you with the remaining keys needed for complete completion.

Gathering these items beforehand ensures that your exploration route remains uninterrupted as you move from one location to the next. You can check your inventory screen to verify that you have enough keys to unlock multiple structures in a single run. Once your materials are ready, the collection process becomes much faster.

Mapping the Northern Surface Route

The surface exploration begins in the Court of Fontaine region, where multiple structures are easily accessible via nearby teleport waypoints. One prominent shrine is situated on the high ridges north of the main city, offering an easy drop-down point for active gliders. Navigating this open terrain requires minimal stamina management if you utilize the local wind currents effectively.

Another surface monument can be found hidden near the cliffs overlooking the northern sea channels. Approaching this area from the higher terrain allows you to avoid unnecessary combat encounters with local wildlife. Clearing these surface locations first establishes a solid foundation for your treasure hunt before you dive into the deep zones.

Navigating Submerged Aquatic Trenches

Fontaine introduces a groundbreaking underwater exploration mechanic that houses several hidden vaults within deep marine canyons. Travelers must plunge into the Elton Trench to discover structures resting along the sea floor amidst vibrant aquatic flora. Reaching these submerged targets requires familiarizing yourself with underwater movement speeds and local dolphin mechanics.

A particularly hidden vault is located within the subterranean currents of the Salacia Plain. Finding this structure demands a keen eye for glowing environmental details and hidden cave systems underneath the reefs. Utilizing these specific coordinates will maximize your efficiency while exploring the multi-layered aquatic zones.

Optimizing the Southern Expansion Path

The final phase of the efficient collection path routes players through the rugged terrain of the Beryl and Belleau regions. Shrines in these areas are often positioned near steep mountain peaks or inside secluded valleys that require careful climbing strategies. Teleporting to the highest nearby waypoints allows you to glide directly to the monument entrances without scaling the rock faces.

Concluding your journey in the southern sub-regions ensures a comprehensive clear of all available open-world vaults. Reviewing your map progress after completing this sequence helps confirm that no Luxurious Chests were overlooked during the run. Following this structured pathing approach provides the fastest path to claiming your premium rewards.
