The Fontaine Research Institute of Kinetic Energy Engineering in Genshin Impact is an intriguing area filled with ruins, floating water bodies, and hidden treasures. But one of the most valuable collectibles here is the Hydroculus, an essential resource used to upgrade the Statue of the Seven in Fontaine. This guide will walk you through the exact locations of all 40 Hydroculus in this region, helping you secure every last one.

Why Collect Hydroculus in the Fontaine Research Institute?

Hydroculus are special collectibles in Fontaine that you can offer to the Statue of the Seven for rewards like:

• Increased Stamina Capacity

• Adventure EXP

• Primogems

• Sigils (for in-region purchases)

The Fontaine Research Institute is a challenging area to explore, with many Hydroculus hidden behind puzzles, locked gates, or perched on difficult-to-reach ledges. But don’t worry — this guide will help you grab them all.

How to Use This Guide
