Genshin Impact: Hydroculus Locations Guide

Finding Hydroculi in Genshin Impact can be challenging as there are a total of 271 to collect. However, it’s a worthwhile endeavor, as collecting them all allows you to upgrade the Statues of the Seven in Fontaine. In return, you will earn rewards like Primogems, Hydro Sigils, Fontaine Shrine of Depths Keys, and more. To assist you in your search, we’ve put together detailed maps outlining the best routes for finding Hydroculi, including those in the newly added Sea of Bygone Eras from Genshin Impact version 4.6.

How to Locate Hydroculi in Genshin Impact

In Fontaine, the northwestern region of Teyvat, Hydroculi appear as small, floating orbs with a bright blue hue. While they are often found perched atop buildings and mountains, a few are submerged underwater, making them trickier to locate.

Once you spot a Hydroculus, simply touch it to collect it — it will automatically be added to your inventory. You’ll need to gather a total of twenty Hydroculi to unlock the first upgrade for the Fontaine Statue of the Seven.
