Best for both Energy generation and team buffing. Energy Regen mainstat + 0.6/s passive Energy — critical for Ye Shunguang rotations. Also provides 10% Combat ATK and a near-permanent 25% DMG Bonus.

Effective due to its passive Energy generation, which matters more than Energy Regen% on Sunna. Note: Bubblegum and Cat's Gaze are separate entities and do not trigger its DMG Bonus — treat it as an Energy sustain option only.

Widely used — Energy Regen mainstat and strong team ATK% buff. Bubblegum provides stacks for itself; Sunna can build her own, making maximum stacks achievable with solid management. ER% loses some value vs. Sunna's low base Energy.

Situationally strong — split EX Specials sustain the CRIT Rate buff, but only works on Ether-weak enemies. Less valuable on Ye Shunguang teams where she is often CRIT Rate capped already.

Team
Sunna appears in virtually every top composition as a universal Support. Her most common pairings are with Aria + Nangong Yu (top Shiyu team) and Ye Shunguang + Zhao, where her Energy generation enables critical rotation timings.
