Genshin Impact is an ever-evolving game, and with the introduction of Fontaine, HoYoverse has expanded on Genshin Impact’s diverse combat system even further. This is through the brand new “Arkhe” system, a special form of energy exclusive to characters hailing from Fontaine. The Arkhe system takes the form of different flowers of energy, Pneuma, and Ousia. If you look closely at your Fontaine characters, such as the Hydro Traveler, you might notice they can utilize “Pneuma” and “Ousia” within their attacks. But what are Pneuma, Ousia, and the Arkhe system in Genshin Impact exactly?
What are Pneuma and Ousia in Genshin Impact?
Pneuma and Ousia are described as “the properties found in the life forms, earth, air, and water veins of Fontaine.” It is the “collision between energies of different properties [that] causes annihilation and the production of greater energies.” However, what’s more important in the case of Genshin Impact is how Pneuma and Ousia attacks interact with certain enemies in the game. When fighting the new “Mek” enemies in Genshin Impact, you might notice using Pneuma or Ousia attacks can disable these enemies, giving you the upper hand in battle.
When fighting a Mek enemy, you need to pay close attention to which Arkhe alignment they have. If you are fighting a Mek with a purple glow, these enemies are Ousia-aligned. If you are fighting a Mek with a yellow glow, you are fighting an enemy that’s Pneuma-aligned. To gain the upper hand in battle against these enemies, you have to use an attack with the opposite Arkhe energy to Overload them, decreasing their energy. For example, if you are fighting an Ousia-aligned enemy, hitting them with a Pneuma attack will Overload them, and vice versa.
It is possible to utilize the power of the Arkhe system without having a character with these capabilities. While exploring Fontaine, you might come across objects known as Pneumousia Blocks. When interacting with these objects, your next attack will be imbued with the power of a Pneuma or Ousia attack. (Interacting with a purple Pneumousia Block will result in an Ousia-imbued attack, and vice versa.)
Occasionally, you will encounter different Pneuma and Ousia-related puzzles while exploring Fontaine. Generally, the rule of thumb with these puzzles is to simply hit the puzzle with an Arkhe attack corresponding to the opposite element. (For example, if you come across a yellow Pneuma relay, hit it with an Ousia attack.)
Which characters in Genshin Impact have Pneuma and Ousia attacks?
As Fontaine is currently brand new, there aren’t many characters in the game who have Arkhe attacks. So far, these are your only options:
- Hydro Traveler: Pneuma
- Lyney: Pneuma
- Lynette: Ousia
To better explore Fontaine, consider building these characters so you can easily defeat Mek enemies and solve Pneuma and Ousia-related puzzles. Download Genshin Impact on its official website here.
