Chevreuse is a 4-star Pyro character who wields a Polearm in Genshin Impact. She serves as the captain of the Special Security and Surveillance Patrol in Fontaine, wearing justice as an ever-present seal upon her heart. As an off-field support character, she excels in Overloaded teams, providing valuable buffs such as ATK% and Pyro and Electro RES Shred. Her combat abilities center around her musket, which fires explosive grenades that split into secondary shells. Her Elemental Skill offers both healing capabilities that scale with her max HP and the ability to generate Overcharged Balls through Overloaded reactions. Like all Fontaine characters, Chevreuse possesses an Arkhe aligned to Ousia, which triggers special explosions when hitting Pneuma-aligned enemies or objects, useful for both combat and puzzle-solving throughout Fontaine.
