Hydroculus

The Hydroculus (plural Hydroculi) is an Adventure Item that can be found scattered across Fontaine. Hydroculi can be offered to any Statue of The Seven in Fontaine for rewards, are limited and do not respawn, and will not appear in Chests.

When a Hydroculus is within close proximity of a player, an icon will appear on their minimap along with a sound effect. Players can also use a Hydroculus Resonance Stone to mark the location of a Hydroculus on the map.

225 Hydroculi can be found in the overworld and 46 in the Sea of Bygone Eras, allowing a player to fully level up the Statues of The Seven in Fontaine with one Hydroculus to spare.
