Honkai: Star Rail’s first two-in-one character is Topaz and Numby, and this duo includes the Fire Hunt character Topaz and her faithful Warp Trotter Numby.
Since you effectively have two units to work with, Topaz and Numby are an interesting duo to use in battle and a fairly complex character to build. There are many factors to consider, so before you bring Topaz and Numby to the battlefield, be sure to understand how their skills work, what materials you need to level them up, and what their best Light Cones and Relics are.
Topaz and Numby skills in Honkai: Star Rail
Topaz and Numby have five different skills you can use in battle, but some of these abilities also have secondary effects or attacks that make their skillset feel a bit more complex.
- “Deficit…” basic attack: Deals Fire damage equal to 50 to 130 percent of Topaz’s attack against a single selected enemy.
- “Difficulty Paying?” skill: Apply the Proof of Debt status to the target opponent, which increases follow-up attack damage against it by 25 to 62.5 percent. Proof of Debt is only active on the most recent target it was triggered on. If there are no opponents affected by Proof of Debt when an ally’s turn begins or when a teammate takes action, Topaz will apply it to a random opponent. Numby will deal 75 to 187.5 percent of Topaz’s attack as Fire damage against the selected target. Using this ability to deal damage is considered a follow-up attack.
- “Turn a Profit!” Ultimate: Numby activates the Windfall Bonanza! state and raises their damage multiplier by 75 to 187.5 percent. This state also increases critical damage by 12 to 31.25 percent. Additionally, when opponents affected by Proof of Debt are struck by a basic attack, skill, or Ultimate delivered by a teammate, Numby’s action is advanced forward by 50 percent. Numby will end the Windfall Bonanza! state after making two attacks.
- “Trotter Market!?” talent: Summons Numby at the beginning of the battle, who starts with 80 speed. When taking an action, Numby initiates follow-up attacks on a single target affected by Proof of Debt effect and deals Fire damage equal to 75 to 187.5 percent of Topaz’s attack. When foes affected by Proof of Debt are hit by a follow-up attack, Numby’s action is advanced forward by 50 percent. This cannot be activated during Numby’s turn, and if Topaz is vanquished in battle, Numby will vanish.
- “Explicit Subsidy” technique: Calls Numby to the overworld. Numby will instantly start searching for Warp Trotters and treasures in the nearby area. Additionally, this ability will restore 60 energy to Topaz after the first attack Numby makes in the next battle. If Topaz is still on the team after using her technique and defeating overworld opponents, the player gets Credits after the battle concludes. This ability can give players up to 10,000 Credits a day. If Topaz uses her Technique in the Simulated Universe and she defeats opponents, she’ll also acquire Cosmic Fragments and have a small chance of gaining one randomly chosen Curio for the team.
