One of the main new mechanics presented in Genshin Impact’s Fontaine is the use of Pneuma and Ousia. In a region that is represented with duality and justice, these new mechanics both within the Visions of the Fontaine Characters and within orbs scattered about the map, the Traveler can use this new batch of puzzles to achieve balance and great rewards.
The Difference Between Pneuma and Ousia-Aligned Visions and Puzzles in Genshin Impact
There are two different types of visions in Fontaine, the Pneuma and Ousia so characters that are exclusive to this region will have one of the two that can be used in battle and to help you solve puzzles. For example, the Traveler’s Hydro Element is aligned with Pneuma but Lynette, who you can claim for free with the release of Fontaine, is aligned with Ousia.
