Exploring the massive Hydro nation in Genshin Impact offers countless hidden treasures, but few rewards match the value found within the Fontaine Shrines of Depths. These specialized structures contain luxurious chests filled with Primogems, local sigils, and essential upgrade resources. Unlocking them requires specific adventure keys that players must earn through dedication and regional exploration milestones.

How to Earn Fontaine Shrine Keys

Acquiring the required keys involves engaging deeply with the unique offering systems established within the Nation of Justice. Players can secure these rare items by leveling up any Fontaine Statue of the Seven using Hydroculus orbs gathered throughout the land. Additionally, offering Hydro Sigils to the Fountain of Lucine outside the majestic Opera Epiclese provides a steady stream of keys at specific milestone levels.

Unlike certain regional items, these keys are interchangeable and can open any structure within the territory. This freedom allows travelers to open the vaults in any order they prefer during their journey. Gathering these resources efficiently requires regular chest hunting and solving regional puzzles across the map.

Surface Shrine Locations Across the Nation

Several of these ancient structures rest on high ground or hidden valleys scattered across the terrestrial expanses of the Hydro region. One prominent shrine sits north of the Court of Fontaine, tucked away in an orchard located just beneath the towering cliffs. Another structure can be discovered near the summit of a hill on the western side of the Elynas mountain range.

Adventurers moving toward the northeast will encounter another shrine situated prominently on the hills north of Marcotte Station. Furthermore, players exploring the area near the New Fontaine Research Institute can scale the steep northern hills to find another hidden vault. Navigating to these land-based landmarks usually requires unlocking nearby teleport waypoints to simplify travel times.

Discovering Underwater Shrines of Depths

Fontaine introduces a captivating twist by placing a select number of its ancient shrines completely submerged beneath the waves. A notable underwater vault is located deep at the bottom of the Elton Trench, nestled safely among large aquatic vegetation. Players must adapt to the localized diving mechanics to reach these oceanic depths safely.

Another aquatic shrine can be accessed by diving just southwest of the ruins formerly belonging to the Central Laboratory. These underwater destinations emphasize the verticality of the region and reward players who actively map out the sea floor. Exploring the underwater terrain carefully ensures that no luxurious chest remains hidden beneath the tides.

Maximizing Your Exploration Rewards

Unlocking each individual shrine contributes significantly to your overall regional exploration completion percentage in the game log. The resources inside are highly valuable for leveling up new characters and preparing for challenging high-level combat scenarios. Planning an efficient travel route ensures you collect the maximum amount of treasure with minimal backtracking.

It is always recommended to mark the locations on your personal map once you discover them to track your progress accurately. By systematically gathering keys and visiting these unique points of interest, you will fully conquer the secrets of this beautiful nation.
