Chevreuse is a support character who can provide various buffs in an Overloaded team composition.

When all party members are Pyro and Electro characters and there is at least one Pyro and one Electro each in the party, after a character triggers the Overloaded reaction, the Pyro and Electro RES of the opponents(s) affected by this Overloaded reaction will be decreased, and an Overcharged Ball will be generated.

For a short duration after Chevreuse fires a shot using her Elemental Skill, she will continuously restore HP to the active character on the field. If an Overcharged Ball is fired, party members' ATK will be increased.

Chevreuse's Elemental Burst deals AoE Pyro DMG and splits into many secondary explosive shells that will burst after a short interval, dealing further Pyro DMG.
