Hey, Trailblazers! It's 2026, and our favorite debt-collecting duo, Topaz and her adorable trotter Numby, have solidified their place as one of the absolute best follow-up attack enablers in Honkai: Star Rail. I remember when she first dropped back in 1.4, and the community was a bit unsure about her. Fast forward to now, and she's an S-tier staple in so many of my teams! Her unique kit, where Numby does most of the heavy lifting, makes her gameplay super fun and dynamic. She's not just a DPS; she's an incredible sub-DPS and support that makes other follow-up attackers like Dr. Ratio and Feixiao absolutely shred through content. Let's dive into the best ways to build her in the current meta!

🔥 Best Relic Sets for Topaz & Numby

Since Numby's follow-up attacks are the core of their damage, we need to build around that. The old 4-piece Firesmith set? Forget it! It's not optimal anymore.

Here are the top-tier relic sets for them in 2026:

  • 4-Piece The Ashblazing Grand Duke: This is the BIS (Best in Slot) for her as a main follow-up DPS. The damage boost is insane!

  • 4-Piece Pioneer Diver of Dead Waters: An amazing alternative, especially if you're running her in a debuff-heavy team with Dr. Ratio. The extra damage against debuffed enemies is perfect.

Don't have those perfect sets yet? No worries! You can use these solid 2+2 combinations while farming:

  • 2pc Musketeer of Wild Wheat (+12% ATK) / 2pc The Ashblazing Grand Duke

  • 2pc Champion of Streetwise Boxing / 2pc Musketeer

  • 4pc Champion of Streetwise Boxing is also a decent temporary holdover.

Main Stats to Target:

  • Body: CRIT Rate / CRIT DMG (Aim for a good balance, like 70/140+)

  • Feet: SPD (Getting her to act faster is key) or ATK%

  • Sphere: Fire DMG Boost

  • Rope: Energy Regeneration Rate OR ATK% (ER rope is often preferred to get her Ultimate up faster for Numby's enhanced attacks!)

💫 Planar Ornament Recommendations

Your planar ornament choice can really fine-tune her role. Here's the breakdown:

Ornament Set Best For... Why It's Good
Duran, Dynasty of Running Wolves Primary DPS Topaz The absolute best for maximizing her personal follow-up attack damage.
Izumo Gensei and Takama Divine Realm Dual-Hunt Teams Perfect if she's paired with another Hunt DPS like Dr. Ratio or Feixiao. The ATK and CRIT DMG buffs are huge!
Inert Salsotto Reliable & Accessible Provides a nice CRIT Rate boost and directly buffs follow-up attack DMG. A classic, safe choice.
The Wondrous BananAmusement Park Numby-Focused Build Gives a massive Crit DMG bonus specifically to summoners like Topaz. Very strong!

✨ Light Cone Guide (From F2P to Whales!)

Topaz is a bit picky with Light Cones because many Hunt cones boost Basic or Skill damage, which isn't her main thing. We want cones that boost follow-ups, overall damage, or her debuffing utility.

S-Tier Signature:

  • "Worrisome, Blissful" (Signature): Obviously her best. It's tailor-made for her and Numby, providing massive follow-up attack buffs and energy.

Excellent 4-Star & F2P Options:

  • "Cruising in the Stellar Sea" (Herta's Shop): The best F2P option! Easy to superimpose, gives ATK% and CRIT Rate. A no-brainer.

  • "Swordplay" (Gacha): Surprisingly strong if you can keep its stacks up on a single target.

  • "Return to Darkness" (Battle Pass): Great if you need that extra CRIT Rate.

  • "Final Victor" & "River Flows in Spring"**: Solid free-to-play picks.

5-Star Stat Sticks:

These aren't perfect, but their high base stats make them work if you have them lying around:

  • In the Night

  • Sleep Like the Dead

  • Baptism of Pure Thought

  • I Venture Forth to Hunt

For Brand New Players: The 3-star "Darting Arrow" can be used temporarily for its CRIT Rate boost!

⚡ Trace Priority & Playstyle Tips

Leveling her traces efficiently is crucial! Here's the order I recommend:

  1. Skill (MAX THIS FIRST!): This applies the "Proof of Debt" debuff. This is the MOST important part of her kit! It makes enemies take 50% more damage from follow-up attacks, which buffs HER, Numby, AND ALL YOUR OTHER FOLLOW-UP ATTACKERS. It's what makes her such a powerful support.

  2. Talent & Ultimate (Level Together):

    • Talent: Governs Numby's actions and damage. Super important.

    • Ultimate: Doesn't deal damage itself but supercharges Numby's next 2 attacks, making them hit MUCH harder. Essential for burst phases.

  3. Basic Attack (Level Last): You barely use it, so just get the minor stat bonuses from leveling it last.

Quick Playstyle Notes:

  • Use her Skill on the main target to mark it with Proof of Debt.

  • Numby acts on its own turn based on its SPD AND whenever Topaz uses her Skill. It's a dance!

  • Use her Ultimate right before you want Numby to unleash a big burst of damage, or to force Numby to act immediately if its turn is far away.

  • She shines in teams with other follow-up attackers. My favorite combos are with Dr. Ratio, Feixiao, Aventurine, or Clara. The damage amplification is unreal!

So that's the 2026 lowdown on building Topaz & Numby! They've gone from a questionable pick to a meta-defining unit. Building them correctly unlocks a whole playstyle centered around powerful, chain-reaction follow-up attacks. It's so satisfying to watch Numby zoom around and enemies just melt. Happy building, and may your relic rolls be blessed with perfect CRIT stats! 🐷✨
