Honkai: Star Rail Firefly Materials and Pre-Farming Guide

October 26, 2026 10 min read

To raise Firefly to level 80 and max all four of her character abilities, you need 65 Raging Heart, the full Thought/Impression/Desire enemy-drop chain, the Borisin Teeth trace family, 120 Moon Rage Fang, 8 Tracks of Destiny, 12 Lost Echo of the Shared Wish, and 2,918,000 Credits in total. You can prepare many items before obtaining her, but there is no permanently guaranteed pre-farm route: stage availability depends on your account progression and the current game version. Use the in-game Interastral Guide to confirm every activity before spending Trailblaze Power.

What does Firefly need for level 80 ascension?

Firefly’s level-80 ascension is a separate cost from upgrading her abilities. The ascension package requires one character-material drop, three tiers of enemy drops, and Credits.

Material Total for level 80 Purpose
Raging Heart 65 Firefly’s character ascension material
Tatters of Thought 15 Enemy-drop material used in ascension
Fragments of Impression 15 Enemy-drop material used in ascension
Shards of Desires 15 Enemy-drop material used in ascension
Credits 308,000 Character-level and ascension expenditure listed for the level-80 target

These figures are the ascension requirement only. They do not include the much larger Credit bill for traces, nor do they include any Light Cone upgrade materials. The material totals come from indexed Firefly guides and character tables; check Firefly’s material panel in your current client before committing your final farming plan.

What does Firefly need to max all four character abilities?

Maxing all four of Firefly’s character abilities uses a different set of materials. Plan for 2,610,000 Credits and the following trace resources in addition to her ascension costs.

Material Total for all four abilities Material group
Tracks of Destiny 8 Rare trace resource
Lost Echo of the Shared Wish 12 High-tier trace resource
Moon Rage Fang 120 Firefly’s Destruction trace family
Shards of Desires 28 Thought/Impression/Desire enemy-drop chain
Fragments of Impression 52 Thought/Impression/Desire enemy-drop chain
Lupitoxin Sawteeth 60 Borisin Teeth trace family
Borisin Teeth 12 Borisin Teeth trace family
Tatters of Thought 36 Thought/Impression/Desire enemy-drop chain
Credits 2,610,000 All four character abilities at their maximum levels

The Destruction trace materials are Borisin Teeth, Lupitoxin Sawteeth, and Moon Rage Fang. Keep this list separate from the ascension table: a stockpile that covers level 80 will still leave you short on trace drops.

How many Credits does a fully built Firefly require?

Adding the listed ascension and ability costs gives 2,918,000 Credits: 308,000 for level 80 plus 2,610,000 for all four abilities. That sum covers the character costs documented in the tables above; it does not include Light Cone upgrades, relic enhancement, or other roster expenses.

Because Credits are a shared account currency, decide whether Firefly is your immediate priority before converting Trailblaze Power into other resources. Keep a written target of 2,918,000 Credits so trace farming does not leave you unable to pay for the final upgrades.

Which materials should you prefarm first?

Start with materials whose totals are large and whose stages you can currently enter, then fill in scarce items as their activities become available. A practical priority order is:

  1. Check the current client’s material panel. Open Firefly’s character screen and record the exact items and quantities shown for your version.
  2. Secure the three enemy-drop tiers. You need 15 Tatters of Thought, 15 Fragments of Impression, and 15 Shards of Desires for ascension, then a further 36 Tatters, 52 Fragments, and 28 Shards for traces.
  3. Work on the Borisin Teeth family. The trace totals are 12 Borisin Teeth and 60 Lupitoxin Sawteeth, so these can become a bottleneck even after ascension materials are complete.
  4. Reserve the high-tier trace items. Set aside 120 Moon Rage Fang, 12 Lost Echo of the Shared Wish, and 8 Tracks of Destiny for the four-ability target.
  5. Build the Credit reserve. Keep 2,918,000 Credits available for the character itself, excluding Light Cone and relic spending.
  6. Farm Raging Heart when its stage is open to you. The level-80 target is 65. The Interastral Guide is the authoritative way to identify the relevant activity and whether your account has unlocked it.

This order is a planning method, not a claim that every account receives the same drop rate or stage access. Your Trailblaze Power efficiency depends on the difficulty tier you can enter and the current version’s activity rules.

Where do Firefly’s trace materials come from?

HoYoWiki identifies Calyx (Crimson) as the activity category that awards Trace Materials. Use the Interastral Guide to select the currently listed Calyx (Crimson) stage for each item, because the exact stage route and unlock requirements can change with progression and version updates.

Calyx (Crimson) trace drops

Trace-material stages are the place to spend Trailblaze Power when you need Moon Rage Fang or the other trace items shown in Firefly’s panel. The guide will display the available difficulty, rewards, and power cost for your account. Do not assume that a stage visible in another player’s guide is already open on your account.

Enemy-drop materials

Tatters of Thought, Fragments of Impression, and Shards of Desires form Firefly’s ascension-and-trace enemy-drop chain. The totals are 51 Tatters, 67 Fragments, and 43 Shards when ascension and all four abilities are considered together. Borisin Teeth and Lupitoxin Sawteeth are trace materials in the separate Borisin Teeth family; their documented trace totals are 12 and 60 respectively.

Before using Trailblaze Power, inspect Firefly’s material screen and the Interastral Guide entry for the exact source. This prevents farming a similarly named drop from the wrong enemy family or spending power on a stage that does not award the tier you need.

Raging Heart and the ascension activity

Raging Heart is Firefly’s Fire ascension material, with 65 required for level 80. The game client will identify the corresponding ascension activity and its unlock state. If the activity is unavailable through normal progression, check whether a current event Warp has temporarily opened the relevant stage.

Can you prefarm Firefly materials before obtaining her?

Often, yes, provided your account can access the relevant activities. HoYoWiki documents a temporary early-access rule: while an event Warp is active, players may enter the corresponding Calyx (Crimson) or Stagnant Shadow stages for materials needed by featured limited five-star characters, even if those stages are not yet unlocked through normal progression.

This access is tied to the active event and can disappear when the Warp ends. Treat it as an opportunity rather than a permanent route. Open the activity from the event or the Interastral Guide, confirm that Firefly’s materials are listed as rewards, and spend power only after the reward preview matches your checklist.

What to verify before farming during an event Warp

  • Firefly is the featured limited five-star character associated with the active Warp.
  • The unlocked activity’s reward preview names the material you need.
  • Your account can enter the displayed difficulty and pay its Trailblaze Power cost.
  • The event’s end time leaves enough time to claim rewards and finish the required runs.

When the event access closes, normal story and account-progression gates apply again. Recheck the Interastral Guide after each major version update instead of relying on an old farming route.

How do you check Firefly’s current stages in game?

The Interastral Guide is the safest source for stage names, unlock status, rewards, and power costs on your account. Follow this workflow whenever you begin a farming session:

  1. Open Firefly’s character screen and select the material icon for the ascension or ability level you intend to raise.
  2. Tap the item’s source or acquisition button to open the Interastral Guide entry.
  3. Read the activity name, reward preview, difficulty options, and Trailblaze Power cost shown for your account.
  4. Compare the displayed reward with your checklist before launching the stage. Confirm whether you need Raging Heart, a Thought/Impression/Desire tier, a Borisin Teeth tier, Moon Rage Fang, or another item.
  5. Record the remaining quantity after each farming session. Stop when the target is met rather than continuing to spend power on a completed material.
  6. Return to the character screen and refresh the total after converting or using materials, since the required amount can be displayed differently for ascension and traces.

This process also catches version changes. If the client’s material panel differs from an older guide, use the client’s current requirement and treat the older figure as historical.

What is the complete Firefly farming checklist?

Use the following combined checklist when your goal is level 80 plus all four maxed character abilities.

Material Combined target Where to validate it
Raging Heart 65 Firefly’s ascension material panel and its linked activity
Tatters of Thought 51 Firefly’s ascension and trace panels
Fragments of Impression 67 Firefly’s ascension and trace panels
Shards of Desires 43 Firefly’s ascension and trace panels
Borisin Teeth 12 Firefly’s trace panel
Lupitoxin Sawteeth 60 Firefly’s trace panel
Moon Rage Fang 120 Firefly’s trace panel and linked Calyx (Crimson) activity
Lost Echo of the Shared Wish 12 Firefly’s trace panel
Tracks of Destiny 8 Firefly’s trace panel and your inventory
Credits 2,918,000 Character ascension and ability upgrade screens

The combined enemy-drop totals are simple additions of the ascension and ability requirements. Keep the original split visible if you are building Firefly in stages: reaching level 80 uses 15 of each Thought/Impression/Desire tier, while the remaining quantities belong to the ability upgrades.

How should you spend Trailblaze Power without wasting it?

There is no single permanent Trailblaze Power budget that applies to every player. Drop yields vary by difficulty and activity rules, and the retrieved material tables do not establish a Firefly-specific run count. Plan from the quantities shown in your client rather than multiplying an assumed yield.

Use the highest unlocked relevant difficulty

For each Calyx (Crimson) or ascension activity, choose the highest difficulty your account can reliably clear. The Interastral Guide displays the reward preview and power cost before entry, allowing you to compare the remaining target with the reward actually offered.

Separate guaranteed targets from opportunistic drops

Raging Heart and the trace families have distinct roles. Do not substitute a surplus of one family for another: excess Borisin Teeth does not satisfy a Moon Rage Fang requirement, and ascension drops do not replace Credits. Track each row independently.

Stop at the target

Once a row reaches its combined target, redirect power to the next deficit. This matters most for Moon Rage Fang, which has the largest listed trace quantity at 120, and for the 2,918,000-Credit reserve that can be consumed quickly by consecutive upgrades.

What mistakes cause Firefly pre-farming problems?

  • Mixing ascension and trace totals: Level 80 needs 65 Raging Heart and 308,000 Credits; maxing all four abilities needs a separate 2,610,000 Credits and its own material list.
  • Counting only the high-tier enemy drops: The lower tiers remain part of the final total. The combined targets are 51 Tatters of Thought, 67 Fragments of Impression, and 43 Shards of Desires.
  • Assuming a permanent early-access stage: Event Warp access is temporary. When the event ends, the normal unlock path may apply.
  • Using an old route guide: Stage names, unlock conditions, and event access can change. Validate the route in the current Interastral Guide.
  • Budgeting for Light Cone upgrades by accident: The listed 2,918,000 Credits cover Firefly’s character ascension and four abilities only.
  • Farming by memory instead of the reward preview: Open the item source from Firefly’s screen and confirm the exact material before every session.

When should you recheck the material list?

Recheck immediately after a major game update, when a new Firefly event Warp begins, and when you reach a previously locked account-progression milestone. The quantities cited here are guide data indexed through September 30, 2026, while stage access is version- and account-dependent. If Firefly’s in-game panel changes, the current client takes precedence.

Frequently Asked Questions

Can I farm Firefly’s materials before I own the character?

Yes, if the relevant activity is already unlocked for your account or a current event Warp grants temporary early access. You do not need Firefly in your roster to accumulate materials, but you should confirm that the activity’s reward preview is tied to her requirements before spending power.

How much Trailblaze Power will Firefly’s full build take?

A universal number of runs or power cannot be established from the published totals alone. Your cost depends on the difficulty you can enter and the reward yield shown in your current client, so use the Interastral Guide’s preview and track the remaining quantity after each session.

Are Firefly’s Light Cone materials included in these totals?

No. The checklist covers Firefly’s level-80 ascension and all four character abilities. Her Light Cone has its own credit and material requirements and should be budgeted separately.

What should I do if my game shows different Firefly requirements?

Use the values displayed on Firefly’s current ascension and ability screens, then confirm the linked activity in the Interastral Guide. Character tables can lag behind a version change, whereas the client reflects the requirements that apply to your account.
