Team Recommendations

Follow-Up Attacks Team

Topaz is recommended to be paired with teammates who can frequently trigger Follow-Up Attacks so she can trigger her own Talent.
Topaz: Fire DPS
Himeko / Clara: Follow-Up DPS
Asta / Yukong: Buffer/Debuffer
Fu Xuan / Luocha / Lynx: Healer/Shielder

Xianzhou Luofu Team

Jing Yuan’s Follow-Up attack is not as frequent as Himeko/Clara’s, so he can’t frequently trigger Topaz’s Talent. But Topaz’s role here is to inflict Proof of Debt to an enemy (especially bosses) so Jing Yuan’s Follow-up attack will deal more damage.
It’s best if your Jing Yuan has Relic [Feet: SPD] and stacks his SPD to be at least 134 to ensure his own efficiency, where his Lightning-Lord’s Hits Per Action can maintain 6 stacks to get that extra Crit DMG from Jing Yuan’s ascension.
Topaz: Debuffer
Jing Yuan: Follow-Up DPS
Tingyun: Buffer
Fu Xuan / Luocha / Bailu: Healer/Shielder
