So, you've met Hanya in the Fyxestroll Garden, huh? That one judge from the Ten-Lords Commission with the intimidating stare and the ability to make your skill point economy sing? Yeah, me too. As a fellow Trailblazer who's been on this cosmic train since the early days, I can tell you that in the wild world of Honkai: Star Rail in 2026, having a solid Harmony unit like her is like finding a credit chip in a forgotten pocket—always a delightful surprise. The game keeps showering us with shiny new five-stars (two per update, no less!), but sometimes, the four-stars are the real MVPs. Hanya, our lone four-star debut in Version 1.5, is one such gem. A Physical Harmony character who doesn't just buff your team but also hands out skill points like they're festival candy. Let me break down everything I've learned about building her, from the grind to the glory.
First things first, let's talk about getting her off the ground. Ascending a character is the bread and butter of progression, and Hanya's menu is… specific. You'll need to cozy up to some IPC Automatons for their Artifex parts and take a trip to a particularly gloomy part of the Luofu.

Here’s the full shopping list for Hanya's Ascension:
| Ascension | Level Req. | Artifex Modules/Cogs/Gyrehearts | Netherworld Tokens | Credits |
|---|---|---|---|---|
| 1 | 20 | 4x Module | - | 3,200 |
| 2 | 30 | 8x Module | - | 6,400 |
| 3 | 40 | 5x Cogwheel | 2x | 12,800 |
| 4 | 50 | 8x Cogwheel | 5x | 32,000 |
| 5 | 60 | 5x Gyreheart | 15x | 64,000 |
| 6 | 70 | 7x Gyreheart | 28x | 128,000 |
| Total | - | 12 Module, 13 Cogwheel, 12 Gyreheart | 50 Tokens | 246,400 |
A quick pro-tip from someone who's farmed this a dozen times: you can't even access the Stagnant Shadow for those Netherworld Tokens until you've finished the Luofu's main story and unlocked the Fyxestroll Garden area. So, if you're a newbie who just pulled her, you've got some Trailblazing to do first! And don't forget to bump up your Equilibrium level—the game won't let you ascend her further otherwise. It's a classic gacha gate, but we persevere!
Now, the real meat of building any character: their Traces. This is where Hanya transforms from "nice support" to "skill point generating, damage-amplifying machine." Her skill tree is split into two groups, and the material costs reflect that. Her Basic Attack caps at level 6, while her Skill, Ultimate, and Talent can go all the way to the majestic level 10.

Let's look at the numbers. For her Basic Attack, you're mostly farming Crimson Calyxes in the Great Mine and… you guessed it, more Artifex parts.
Basic Attack Trace Costs:
-
Crimson Calyx Mats: 2 Harmonic Tune, 6 Ancestral Hymn, 8 Stellaris Symphony.
-
Artifex Parts: 4 Modules, 5 Cogwheels, 5 Gyrehearts.
-
Credits: A cool 192,000.
Simple enough. But the big investment is in her core kit. Leveling her Skill, Ultimate, and Talent is what makes her sing. This table should save your sanity:
| Trace Level | Crimson Calyx Mats | Artifex Parts | Echo of War Mats (Cocolia) | Tracks of Destiny | Credits |
|---|---|---|---|---|---|
| 2 | - | 2x Module | - | - | 2,000 |
| 3 | 2x Harmonic Tune | 4x Module | - | - | 4,000 |
| 4 | 2x Ancestral Hymn | 2x Cogwheel | - | - | 8,000 |
| 5 | 4x Ancestral Hymn | 3x Cogwheel | - | - | 16,000 |
| 6 | 6x Ancestral Hymn | 5x Cogwheel | - | - | 24,000 |
| 7 | 2x Stellaris Symph. | 2x Gyreheart | - | - | 36,000 |
| 8 | 4x Stellaris Symph. | 3x Gyreheart | 1x Regret of Infinite Ochema | - | 64,000 |
| 9 | 6x Stellaris Symph. | - | 1x Regret of Infinite Ochema | - | 128,000 |
| 10 | 11x Stellaris Symph. | - | 1x Regret of Infinite Ochema | 1 | 240,000 |
| Total | 2x Tune, 12x Hymn, 23x Symphony | 6 Module, 10 Cogwheel, 5 Gyreheart | 3x Regret | 1x Track | 522,000 |
Phew. That's a lot of Stellaris Symphonies and three trips to beat up Cocolia's Echo of War. And that one precious Tracks of Destiny? You better believe I hoard those like Gepard hoards defense stats. The total credit cost for her traces alone is over 700,000. I don't know about you, but my credit balance is perpetually crying.
So, why go through all this? Because Hanya is uniquely brilliant. In a game where skill points are the currency of combat, her ability to generate them reliably is pure gold. She doesn't just sit there looking pretty (though she does that too); she actively fuels your hypercarries like Imbibitor Lunae or Jingliu, letting them spam their powerful skills turn after turn. Her Ultimate also applies a juicy damage vulnerability debuff on enemies. It's a simple, elegant kit that slots into so many teams.
Building her is a journey—a grind through the IPC's robot junkyard, the melodic halls of the Crimson Calyx, and the frozen throne of Jarilo-VI's former leader. But when you finally have her at level 80 with her key traces maxed, watching your team operate with seamless, skill-point-positive fluidity? That's the Harmony path working its magic. She may be a four-star in a five-star world, but in my roster, Hanya is priceless. Now, if you'll excuse me, I have some Automatons to disassemble. Again.
