In Wuthering Waves, Cartethyia is an Aero sword user who employs the Erosion effect to nuke targets during combat. She can sacrifice her HP and transform into Fleurdelys, unleashing new skill sets. However, her damage output will vary based on the number of sword shadows that are active during combat and the target’s Erosion stacks.
You must also pair her with proper companions to make the most of her kit. This article explores some of the best teams for Cartethyia in Wuthering Waves.

Ciaccona and Aero Rover are certainly the best companions for Cartethyia in Wuthering Waves, due to their ability to apply Aero Erosion. They also have access to several different skill sets, which can further increase the damage output of the frontrunner. For instance, Ciaccona can unleash off-field attacks with her Sylphs and can also group up targets.
Ciaccona’s Ultimate ability can buff the Aero damage of all allies, while her Outro Skill amplifies the Erosion effect. You would want to use Cartethyia to stack the sword shadow and swap over to Aero Rovers. Once their Outro Skill is available, switch to Ciaccona. Use her Resonance Liberation and attack with Fleurdelys.
2) Cartethyia+ Ciaccona+ Shorekeeper

You can swap Aero Rover from the last team comp with Shorekeeper for this one, since Ciaccona can assist Cartethyia during combat by herself. Ciaccona is capable of applying Aero Erosion stacks on enemies. This will allow Fleurdelys to deal more damage via her Resonance Liberation finisher.
Ciaccona’s ability to boost the Aero damage and amplify Erosion stacks is unmatched, making her a crucial member of the team. Meanwhile, Shorekeeper can be swapped for any other ardent support unit. However, by doing so, you will miss out on the buffs she has to offer.
Wuthering Waves’ Shorekeeper can also heal her entire squad, although you may not need it to protect Fleurdelys. The latter can heal back up after activating the massive nuke from her Resonance Liberation.
3) Cartethyia+ Aero Rover+ Aalto

A more accessible yet still effective team composition for Cartethyia consists of Aero Rover and Aalto. This mono-elemental team relies on quick swaps to apply maximum Erosion stacks while also distributing the Outro Skill buffs. Use Cartethyia to deploy the sword shadow and switch over to Aero Rovers to apply Erosion.
The Rovers can also increase the maximum DoT stack the target can receive. Before switching to Cartethyia, fill up Aalto’s Concerto Energy, which should be a quick process. By doing so, Fleurdelys will receive the Aero DMG buff.
