Deals Fire DMG equal to 50%–110% of Topaz's ATK to a single enemy.


Skill - Difficulty Paying?

Inflicts a single target enemy with a Proof of Debt status, increasing the DMG it takes from follow-up attacks by 25%–55%. Proof of Debt only takes effect on the most recent target it is applied to. If there are no enemies inflicted with Proof of Debt on the field when an ally's turn starts or when an ally takes action, Topaz will inflict a random enemy with Proof of Debt.
Numby deals Fire DMG equal to 75%–165% of Topaz's ATK to this target. Using this Skill to deal DMG is considered as launching a follow-up attack.

Numby enters the Windfall Bonanza! state and its DMG multiplier increases by 75%–165% and CRIT DMG increases by 12.5%–27.5%. Also, when enemies with Proof of Debt are hit by an ally's Basic ATK, Skill, or Ultimate, Numby's action is Advanced Forward by 50%. Numby exits the Windfall Bonanza! state after using 2 attacks.


Talent - Trotter Market!?

When enemies afflicted with Proof of Debt receive an ally's follow-up attacks, Numby's action is Advanced Forward by 50%. The action Advance Forward effect cannot be triggered during Numby's own turn.
When Topaz is downed, Numby disappears.


Technique - Explicit Subsidy

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
Blade / Clara: Follow-Up DPS
Bronya / Asta / Yukong: Buffer
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


Eidolons

E2: Bona Fide Acquisition

E3: Seize the Big and Free the Small
Skill Lv. +2, up to a maximum of Lv. 15.
