The Fontaine region of Genshin Impact, which made its debut in Version 4.0, is associated with the Hydro element. Keeping with tradition, the main collectible of Fontaine is the Hydroculus, which is a Hydro-themed version of the orbs that Genshin Impact players have been collecting since the game’s initial release all the way back in 2020.
While Fontaine might seem like a smaller region than Sumeru or Inazuma, its size is deceiving since it is home to multiple underground sections and freely explorable bodies of water. There are 85 Hydroculi hidden across Fontaine, and if you’re looking to collect them all to upgrade the region’s Statues of the Seven, this guide will walk you through where to find them all.
All Hydroculus Locations in Genshin Impact
As always, you can find Hydroculi floating throughout Fontaine. Some of them are laying in plain sight, while others require puzzles to be solved in order to claim them. Since Fontaine has such a huge focus on swimming, remember that most will be underwater. Plus, some may be hidden underground.
