Why this duo works
Qiyana can dive into a fight with multiple dashes and lock enemies down with Supreme Display of Talent(R), while Yuumi stays attached and follows her into the engage. Yuumi's shield, healing and slow help Qiyana reach her burst and survive the return damage.
Playing the duo
Yuumi's You and Me!(W) lets her follow Qiyana's Audacity(E) and Terrashape(W) dashes while remaining untargetable, and Zoomies(E) passes its shield and movement speed to Qiyana.
Qiyana's Supreme Display of Talent(R) stuns enemies in its shockwave, giving Yuumi time to land more waves of Final Chapter(R) while healing Qiyana and nearby allies.
How to play as Qiyana
Signal your river or wall engage so Yuumi can attach and prepare her shield before you commit. Use Supreme Display of Talent(R) to hold the group in place for Yuumi's follow-up waves.
How to play as Yuumi
Attach before Qiyana enters, then use Zoomies(E) as she dashes in and channel Final Chapter(R) while Qiyana's ultimate holds enemies in place.
