Hydrograna are the Hydro variant of the Grana spirits in Genshin Impact , and are abundant in Fontaine. See what these grana are, what they're used for, how to use them, and all known information about them here!

How to Use Hydrograna and Effects

Acquire 3 Hydrograna for a Hydro Core

Obtaining 3 Hydrograna will result in a Hydro Core, which will form a Hydro Ring around your active character that will perpetually apply Hydro to targets within their immediate vicinity.

Activation and Expiration

The Hydro Core and its Ring will activate when your active character gets affected by Hydro, even when you've acquired only one Hydrogranum

The Core and Ring will also expire after a certain duration, so you'll need to move fast if you want to solve those puzzles!

Used to Solve Puzzles

Along with a new nation or region comes new sets of puzzles that offer big rewards to Travelers. Hydrograna is often used to solve many of these said puzzles, but are not very useful in combat unless you're looking to set up Hydro-related Elemental Reactions.

Hydro Core Totems

In certain puzzles, Hydro Core Totems will be present, wherein you can install Hydro Cores within them.

While installed within a totem, the Hydro Core and its Ring will stay in place and not expire, effectively freeing your hands to grab more Hydrograna and solve a puzzle in a different area!
