Exploring the vast Hydro region of Fontaine in Genshin Impact reveals a beautifully layered world filled with unique exploration mechanics and ancient architecture. Among the most lucrative targets for dedicated adventurers are the regional Shrines of Depths, which seal away high-tier Luxurious Chests packed with Primogems and rare materials. Successfully locating and unlocking every single one of these structures requires a calculated approach that covers both the towering surface cliffs and the deeply submerged aquatic trenches.

Securing Your Keys Before Departure

Before plotting an efficient path across the Hydro nation, travelers must acquire the corresponding keys required to break the ancient seals. These specialized items are earned primarily by leveling up the Statue of the Seven and offering collected Hydroculi to the regional pool system. A few additional keys are unlocked as milestones when you increase your overall Fountain Reputation level through weekly tasks and world exploration quests.

Attempting to reach the structures without these keys will result in unnecessary backtracking through complex multi-layered zones. Players should prioritize gathering their keys first to ensure their journey remains efficient and uninterrupted. Once your inventory is properly stocked, you can begin executing an optimized pathing sequence across the sub-regions.

Navigating the Surface Shrines of the North and South

The first stage of a streamlined route focuses on the landmarks situated firmly on the surface terrain. Travelers should start by teleporting to the rolling hillsides of the Belleau Region to claim the southernmost structure near the standard pathways. From there, you can chart a course northward toward the Court of Fontaine, where another shrine sits prominently on the high cliffs overlooking the main city structures.

Moving further northeast reveals additional surface monuments nestled within the rugged terrain of the Fontaine Research Institute. Navigating these mountainous zones efficiently requires utilizing nearby teleport waypoints to bypass steep climbing challenges. Ensuring you clear these high-altitude locations early allows you to focus the rest of your expedition on the massive underwater segments.

Diving Into Submerged Treasures and Aquatic Trenches

Fontaine introduces a groundbreaking underwater exploration mechanic that expands the horizontal map into deep vertical layers. To find the remaining reward locations, players must dive directly into the deep aquatic trenches, such as the Elton Trench and the Thalatta Submarine Canyon. These hidden structures are often tucked away behind giant coral formations or inside dark trenches that require careful camera tracking to spot.

While exploring these depths, players will encounter unique environmental mechanics that require underwater combat or solving quick light puzzles to gain full entry. Utilizing the marine abilities borrowed from local aquatic creatures will help you navigate the heavy currents and defend against hostile ocean creatures. Successfully mapping out this aquatic path ensures that you can unlock the luxurious chests hidden beneath the waves with absolute ease.
