Honkai Star Rail Topaz and Numby kit – All Skills, Traces, & Eidolons

Topaz and Numby make up Honkai: Star Rail's first two-in-one unit: Topaz, a young but accomplished Senior Manager of the IPC's Strategic Investment Department, and Numby, a Warp Trotter searching for riches. The two flit from world to world, collecting debt and forcing citizens to fall under the IPC's management. In battle, Topaz and Numby are a Fire unit following the Path of The Hunt. If you're undecided about pulling for this unique unit, then here's everything you need to know about Topaz and Numby's Skills, Traces, and Eidolons in Honkai: Star Rail.

Basic Attack: Deficit…

Deals Fire DMG equal to a percentage scale 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 a percentage scale (1). 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 a percentage scale (2) of Topaz's ATK to this target. Using this Skill to deal DMG is considered as launching a follow-up attack.

• Level Ten: 50% (1) / 150% (2)
• Level Twelve: 55% (1) / 165% (2)

Talent: Trotter Market!?

Summons Numby at the start of a battle. Numby has 80 SPD by default. When taking action, Numby launches follow-up attacks on a single enemy target afflicted with Proof of Debt, dealing Fire DMG equal to a percentage scale of Topaz's ATK.

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

Summons Numby when Topaz enters the overworld. Numby will automatically search for Basic Treasures and Trotters within a set radius.
