Numby is here, along with his partner – Honkai Star Rail’s Topaz. Just kidding, Topaz is the star here even if her little Warp Trotter buddy is adorable. She’s a debt collector for the Interastral Peace Corporation and is a five-star, fire-wielding unit, specializing in follow-up damage and buffing her team. Here’s the best Topaz build to max out her damage.

Here’s everything you need to know about building Honkai Star Rail’s Topaz (and Numby):
What’s the best Honkai Star Rail Topaz build?
Topaz is a five-star, fire-using character who follows the path of The Hunt.
| Best light cone | Worrisome, Blissful |
| Light cone substitutes | Sleep Like The Dead, Swordplay |
| Best relic set | Ashblazing Grand Duke |
| Planar ornaments | Duran, Dynasty of Wolves |
| Main stats | Body – Crit rate/damage Feet – Attack Link rope – Attack Planar sphere – Fire damage bonus |
| Sub stats | Crit rate, crit damage, attack, speed |
Topaz specializes in follow-up attacks and relies on crit stats to really pack a punch. Her piggy friend Numby features in most of her attacks. The drawback with Topaz is that she only really deals single-target damage, but can really help in a follow-up and debuff-centered team.
The overall best light cone you can equip Topaz with is her signature ‘Worrisome, Blissful’, but a good Hunt-aligned cone that boosts follow-up damage will also work. As for relics, you want to get her a good set of Firesmith of Lava-Forging to boost her fire damage and focus on attack, crit, and speed substats.
How do I use Topaz?
Topaz excels as a sub-DPS (though Numby is the true star of the show) and as a support unit for characters that deal in follow-up attacks. Her kit allows her to improve the damage that her follow-ups deal to a ridiculous point.
If you’re focusing on a sub-DPS Topaz, then using her skill increases the damage enemies take from follow-up attacks from her and other party members. If you’re using her as your main DPS, then using buffers like Asta, March 7th, or Tingyn will improve her personal damage. And Numby’s, let’s not forget about Numby!
What is the best Topaz light cone?
Topaz’s best light cone is her signature, Worrisome, Blissful. However, if you’re not in a position to pull for that, any of these other Hunt light cones will be good for Topaz.
| Worrisome, Blissful | This light cone increases Topaz and Numby’s crit rate by 18%. Her follow-up damage gets a 30% increase as well. When Topaz uses a follow-up attack, the target gets the Tame state. This can stack two times. When Topaz or other teammates hit this target, each stack of Tame it has increases your crit damage by 12% | Light cone banner |
| Swordplay | Each time Topaz hits the same target, her damage increases by 8%, stacking up to five times. This is reset when she changes targets | All banners |
| Cruising in the Stellar Sea | Increases Topaz’s crit rate by 8%, and increases her crit rate against enemies with 50% or less HP by a further 8%. When she defeats an enemy, her attack increases by 20% for two turns | Purchase from Herta’s Store |
| Only Silence Remains | Increases Topaz’s attack by 16%. If there are two or fewer enemies on the field, her crit rate increases by 12% | All banners |
| Darting Arrow | When Topaz defeats an enemy, her attack increases by 24% for three turns | All banners |
What are the best relics for Topaz?
To get the best damage out of Topaz, the best relics to equip her with is a full set of the Ashblazing Grand Duke. Remember to keep an eye on substats, too, but aim for a fire-damage-boosting piece in there. If you plan on having at least one debuff on enemies at all times, you can use a full set of Pioneer Diver of Dead Waters on Topaz to up the damage her, and her teammates, deal to said debuffed enemies.
Relics
| The Ashblazing Grand Duke | Two pieces: Increases follow-up damage by 20% Four pieces: When Topaz uses a follow-up attack against an enemy, it increases her attack by 6% each time the follow-up deals damage. This can stack a maximum of eight times and lasts for three turns | Cavern of Corrosion: Path of Darkness in Fyxestroll Gardens |
| Pioneer Diver of Dead Waters | Two pieces: Increases damage Topaz deals to debuffed enemies Four pieces: Increases crit rate by 4%. Topaz deals 8/12% extra crit damage to enemies with two/three debuffs. If Topaz inflicts a debuff onto an enemy, these effects increase by 100% for one turn | Cavern of Corrosion: Path of Dreamdive in the Reverie |
| Musketeer of Wild Wheat | Two pieces: Increases attack Four pieces: Topaz’s speed increases by 6% and her basic attack damage by 10% | Cavern of Corrosion: Path of Drifting on Jarilo-VI |
| Firesmith of Lava -Forging | Two pieces: Increases fire damage Four pieces: Increases Topaz’s skill damage by 12%. After unleashing her ultimate, her fire damage increases by 12% for the next attack | Cavern of Corrosion: Path of Conflagration on the Xhianzhou Luofu |
Planar ornament
| Duran, Dynasty of Running Wolves | Two pieces: When allies use follow-up attacks, Topaz gains one stack of Merit. This can stack five times. Each stack increases her own follow-up damage by 5%. If Topaz has five stacks of Merit, her crit damage increases by 25% | Divergent Universe reward |
| Space Sealing Station | Two pieces: Increases Topaz’s attack by 12%. When her speed reaches 120 or higher, attack increases by a further 12% | Immersion Reward devices in World 3 of the Simulated Universe |
| Inert Salsotto | Two pieces: Increases Topaz’s crit rate by 8%. When her current crit rate reaches 50% or more, her ultimate and follow-up damage increases by 15% | Immersion Reward devices in World 6 of the Simulated Universe |

- Body: Crit damage

Sub-stats:
- Crit rate/damage (aiming for a 1:2 ratio)

What are the best Topaz team comps?
Topaz (and Numby) work very well in a mono-fire or almost mono-fire team comp, though any units focusing on follow-up damage – like Jing Yuan – are welcome. Topaz is a key teammate for Dr. Ratio and Feixiao, who both appreciate follow-up attacks.
Buffers such as Asta and Robin will help to improve Topaz’s performance. And Numby’s, of course.
| Topaz | Aventurine | Robin |  Feixiao |
| Topaz | Aventurine | Robin |  Dr. Ratio |
| Topaz | Ruan Mei | Dr. Ratio |  |
| Topaz | Asta | Himeko | |
What are Topaz’s abilities?
Topaz and Numby work together to deal damage on the field, and here’s what their skills do for us.
Active skills
| Basic attack | Deficit… Topaz deals fire damage equal to 90% of Topaz’s attack to a single enemy |
| Skill | Difficulty Paying? Topaz inflicts the Proof of Debt state on a single enemy, increasing damage taken by follow-up attacks by 43%. This only takes effect on the most recent target. If no enemies are inflicted with Proof of Debt when an ally’s turn starts, Topaz inflicts a random enemy with the state. Numby deals five damage equal to 131% of Topaz’s attack to this target. Using this skill counts as a follow-up attack |
| Ultimate | Turn a Profit! Numby enters the Windfall Bonanza state, where its damage and crit damage increase. Every time an ally’s skill, basic attack, or ultimate hits an enemy inflicted with Proof of Debt, Numby’s action moves forward. After Numby launches a set number of attacks, this effect dispels |
Talent
| Trotter Market!? | Topaz summons Numby at the start of the battle. Numby has 80 speed by default. When Topaz makes a move, Numby launches follow-up attacks on a single enemy afflicted with Proof of Debt, dealing fire damage equal to 131% of Topaz’s attack. When enemies afflicted with Proof of Debt receive an ally’s follow-up attacks, Numby’s action advances forward 50% |
Technique
| Explicit Subsidy | Topaz summons Numby while on a map outside of combat, who seeks out trotters and treasure chests in the nearby area. Warp trotters don’t get scared of its presence and will approach Numby. Entering a battle with this skill regenerates energy for Topaz after Numby’s first attack, and finishing a battle started in this way earns more credit or cosmic fragments |
Traces
| Overdraft | When Topaz uses her basic attack to deal damage, it counts as a follow-up attack |
| Financial Turmoil | Increases Topaz and Numby’s damage dealt to enemies with fire weakness |
| Stonks Market | After Numby attacks in the Windfall Bonanza! state, Topaz regenerates energy |
What are Topaz and Numby’s eidolons?
If you happen to get lucky and pull more than one of the fiery duo, here are the perks you can unlock.
| E1 | Future Market When enemies afflicted with Proof of Debt receive follow-up attacks, they enter the Debtor state. This takes effect once within a single attack. This state increases the crit damage of follow-up attacks that hit the target enemies by 25%. It can stack twice |
| E2 | Bona Fide Acquisition After Numby takes action and launches an attack, Topaz regenerates five energy |
| E3 | Seize the Big and Free the Small Increases Topaz’s skill level by two, up to a maximum of 15. Also increases her basic attack level by one, to a maximum of ten |
| E4 | Agile Operation After Numby’s turn begins, Topaz’s action advances forward by 20% |
| E5 | Inflationary Demand Increases Topaz’s ultimate level by two, up to a maximum of 15. Also increases her talent by two, up to a maximum of 15 |
| E6 | Incentive Mechanism Numby’s attack count during the Windfall Bonanza! state increases by one, and its fire resistance penalty increases by 10% when it attacks |
