Playstyle Guide & Rotation
Sunna skill kit and abilities highlights her ability as a mainly off field support character that can amplify the damage output of Attack and Anomaly Specialty Agents while also facilitating different Ether Veil effects.
Sunna’s main gimmick revolves around her Angel’s Accord buff on allies and the Cat’s Gaze debuffs on enemies. When Angel’s Accord is granted to allies, they will gain a massive attack and damage buff proportional to Sunna’s own attack stat. Additionally, Sunna’s attacks while she is on the field will inflict the Cat’s Gaze effects on enemies. Enemies marked by Cat’s Gaze will take more damage and additional effects based on if an Attack Specialty Agent or an Anomaly Specialty Agent attack into them. Cat’s Gaze can be applied to enemies even when Sunna is off field.
Additionally, Sunna can help set up the special Ether Veil effect for allies and help maintain Ether Veil, allowing characters that want Ether Veil to remain on the field for as long as possible to take full advantage of its effects.

| Ye Shunguang | Dialyn | Sunna |
| Main DPS | Sub DPS | Support |
| Essential | Flexible | Flexible |
