I've been reworking my Topaz & Numby in Honkai: Star Rail here in 2026, and let me tell you, figuring out exactly what to farm for this Fire Hunt duo still trips up plenty of players. Topaz isn't your standard single-target Hunt character—she and Numby operate almost like a two-for-one deal. Numby acts like a tiny independent partner with its own turn, which honestly makes the pair feel more like a follow-up attack tag team than a lone sniper. Before you can push Topaz to level 80 and max out her Traces, you'll need to grind a very specific shopping list of materials.

The first big chunk of farming happens on Jarilo-VI, and no joke, you'll be seeing a lot of Silvermane enemies. Once you understand where everything drops, though, the process becomes a steady rhythm rather than a chaotic grind.

Ascension Materials for Topaz & Numby

When it comes to getting Topaz through all her Ascension stages, the Silvermane family of items sits at the top of the list. You'll need Silvermane Badge, Silvermane Insignia, and Silvermane Medal. These drop from a wide range of enemies on Jarilo-VI, including Silvermane Cannoneer, Silvermane Soldier, Silvermane Gunner, and Silvermane Lieutenant. You can also grab them from enemies like Vagrant, Everwinter Shadewalker, Incineration Shadewalker, Automaton Beetle, and Automaton Hound.

If you're short on a specific tier, remember to use the Synthesizer. Converting three lower-quality items into one higher-quality version is a lifesaver, especially as your Ascension needs start demanding Insignias and Medals instead of plain Badges. You can also buy a small number from the Embers Exchange shop, but most of your stock will come from simply exploring and fighting across Jarilo-VI.

The other Ascension item is Searing Steel Blade, which was introduced back in Version 1.4. Unlike the Silvermane materials, this one can't be pre-farmed on older maps. You'll need to challenge the Stagnant Shadow: Shape of Scorch a few times. In total, Topaz requires 65 copies of Searing Steel Blade to reach level 80. Since each run costs Trailblaze Power, you may need to split this across several days—trying to do it all in one sitting is a quick way to drain your reserves.

Here's a quick overview of what each Ascension stage asks for:

On top of the materials, you'll also need 308,000 Credits to finish Topaz's Ascension. That amount is easy to earn by running the Calyx (Golden): Bud of Treasures a few times. Compared to what comes next, the Ascension grind feels almost relaxing.

Trace Materials for Topaz & Numby

Now, the real time sink is Topaz's Traces—her abilities. This is where the material list gets longer and your Synthesizer gets a workout.

First, you'll need even more of the Silvermane Badge, Silvermane Insignia, and Silvermane Medal family. The amount needed for Traces is significantly higher than for Ascension, so don't stop farming Jarilo-VI just because you hit level 80. Constantly converting lower-tier badges into higher-tier medals is essential here, otherwise you'll end up with an absurd surplus of basic Badges and nothing to spend them on.

Next up are the Hunt-specific materials: Arrow of the Beast Hunter, Arrow of the Demon Slayer, and Arrow of the Starchaser. These come from the Calyx (Crimson): Bud of the Hunt. If you've previously built another Hunt character like Seele, you might already have a stockpile. If not, be prepared for a day-long grind—each Calyx run only drops a limited number of arrows, and Topaz needs a lot of them.

For her higher-level Traces, you'll also need Regret of Infinite Ochema, which only drops from the weekly boss fight against Phantylia. Because weekly boss rewards are capped, this part can take several weeks to complete, especially if you're building another character at the same time. Finally, you'll need Tracks of Destiny, which you can earn from limited-time events, Nameless Honor, and the weekly Simulated Universe reward track.

Here's a breakdown of the Trace resources and their main sources:

And the Credits? You'll need a whopping 3 million Credits to fully level all of Topaz's abilities. That's nearly ten times the Ascension cost, so keep that Golden Calyx on your daily rotation.

At times, Numby almost feels like it's judging my farming route, but in a cute way. The little guy just keeps trotting along while I grind out another round of Silvermane badges. If you pace yourself and focus on one material family at a time, building Topaz & Numby becomes a satisfying long-term project rather than an overnight rush. Take your time, run the Calyxes and Stagnant Shadows when your Trailblaze Power allows, and before you know it, you'll have a fully maxed follow-up attack duo ready to melt enemies.
