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 damag.

Here’s how to build Honkai Star Rail’s Topaz.

What’s the best Honkai Star Rail Topaz build?

Best light cone Worrisome, Blissful
Light cone substitutes Sleep Like The Dead, Swordplay
Best relic set Ashblazing Grand Duke
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 is a five-star, fire-using character who follows the path of The Hunt, and her piggy friend Numby features in most of her attacks. She specializes in follow-up attacks and relies on crit stats to really pack a punch. The drawback with Topaz is that she only really deals single-target damage.

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 Honkai Star Rail’s 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.

Light cone Effect How to obtain
Worrisome, Blissful (five-star) 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 (alongside Topaz)
Swordplay (four-star) 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
Sleep Like the Dead (five-star) Increases Topaz’s crit damage by 30%. When her basic attack or skill does not result in a crit hit, her crit rate increases by 36% for one turn. This can only trigger once every three turns Standard banner
Only Silence Remains (four-star) 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 (three-star) When Topaz defeats an enemy, her attack increases by 24% for three turns All banners

What are the best relics for Topaz?

While we don’t know the ins and outs of her full kit, a two or four-piece of fire-boosting relics won’t go amiss, nor will it be a bad thing to add extra attack to her stats.

Relic Effect How to obtain
The Ashblazing Grand Duke Two equipped: Increases follow-up damage by 20%
Four equipped:
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

Topaz’s speed increases by 6% and her basic attack damage by 10%

What are the best Honkai Star Rail 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. Buffers such as Asta and Tingyun will help to improve Topaz’s performance. And Numby’s, of course.

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:

Skill Effect
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:

Skill Effect
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:

Technique Effect
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:

Trace Effect
Overdraft (unlocked at ascension two) When Topaz uses her basic attack to deal damage, it counts as a follow-up attack
Financial Turmoil (unlocked at ascension four) Increases Topaz and Numby’s damage dealt to enemies with fire weakness
Stonks Market (unlocked at ascension six) 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.

Eidolon Effect

Level two: Bona Fide Acquisition After Numby takes action and launches an attack, Topaz regenerates five energy
Level three: 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
