Version 3.8 Banner Schedule and Timeline

Version 3.8 releases December 16, 2025 (North America), running through January 7, 2026 (UTC-5)—22 days to secure both characters. Version cycle concludes January 29, 2026 when 4.0 arrives.

Trailblaze Power caps at 240, regenerating 1 per 6 minutes at 4:00 AM daily reset = 240 Power daily without refreshes. Each Cavern of Corrosion costs 40 Power = 6 domain runs daily.

For Stellar Jade reserves, Honkai Star Rail Stellar Jade top up for 3.8 Dahlia and Firefly pulls through BitTopup ensures sufficient premium currency with competitive pricing and instant delivery.

Pre-Farm Timeline

Relic farming requires Trailblaze Level 40 minimum. World Level 6+ provides optimal drops with guaranteed 5-star pieces. The 60/30/10 stamina allocation: 60% to priority caverns, 30% to secondary domains, 10% to planar ornaments.

Complete builds for both characters need 15-20 days of focused farming without refreshes. This assumes stopping at 70% optimal substats—the efficiency threshold where further farming wastes resources.

The Dahlia: Complete Relic Analysis

The Dahlia operates as Fire element Super Break damage dealer scaling from Break Effect. Optimal build targets 360%+ Break Effect with Speed breakpoints at 145 or 160+ depending on team composition.

Best-in-Slot Relic Sets

Iron Cavalry Against the Scourge (4-piece) - Path of Cavalier, Penacony Grand Theater

Honkai Star Rail Iron Cavalry Against the Scourge relic set pieces showing Break Effect bonuses

  • 2-piece: +16% Break Effect
  • 4-piece: Ignores 10% enemy DEF on Break DMG at 150% Break Effect
  • At 250% Break Effect: Ignores additional 15% DEF on Super Break DMG

Forge of the Kalpagni Lantern (2-piece) - Simulated Universe World 3+

Honkai Star Rail Forge of the Kalpagni Lantern planar ornament set with Speed and Break Effect stats

  • +6% Speed
  • +40% Break Effect for one turn when hitting Fire weakness enemies

Alternative: Thief of Shooting Meteor (4-piece) from Path of Jabbing Punch, Jarilo-VI offers +16% Break Effect (2-piece) and 3 Energy on Weakness Break (4-piece). However, Iron Cavalry's DEF ignore outperforms for damage ceiling.

Main Stat Priority

  • Body: ATK%
  • Feet: Speed
  • Sphere: Fire DMG% or ATK%
  • Rope: Break Effect%

Non-negotiable configuration. Deviations significantly reduce damage output.

Substat Priorities

Break Effect > Speed > ATK%

  • 145 Speed: Minimum for comfortable rotations
  • 160+ Speed: Advanced team compositions
  • Calculate Speed including Forge of the Kalpagni Lantern's +6% bonus

Firefly: Optimal Relic Builds

Firefly shares identical relic requirements with The Dahlia. Super Break build targets 360%+ Break Effect, 2600+ ATK, and Speed breakpoints at 150 base or 155 (164 with buffs).

Top Relic Sets

Iron Cavalry Against the Scourge (4-piece) - Same as The Dahlia. DEF ignore at 150% and 250% Break Effect maximizes Super Break damage.

Forge of the Kalpagni Lantern (2-piece) - +40% Break Effect when hitting Fire weakness creates burst damage windows.

Alternative: Talia: Kingdom of Banditry grants +16% Break Effect baseline with +20% Break Effect at 145 Speed. Works when Simulated Universe farming proves unfavorable, though Forge generally outperforms.

Main Stats

  • Body: ATK% (reaching 2600+ ATK)
  • Feet: Speed (150 or 155 breakpoints)
  • Sphere: ATK%
  • Rope: Break Effect%

2600+ ATK ensures sufficient base damage. Lower values reduce overall damage even with optimal Break Effect.

Speed Tuning

  • 150 base Speed: Standard compositions
  • 155 Speed: Reaches 164 with buffs for rotation optimizations

Calculate Speed including Forge's +6% bonus and Feet slot Speed main stat. 5-star relics enhance to +15 maximum.

Relic Set Overlap: Farm Efficiently

The Dahlia and Firefly share identical core requirements, creating unprecedented farming efficiency.

Shared Sets

Iron Cavalry Against the Scourge - Farm Path of Cavalier exclusively until obtaining optimal pieces for both characters. Single domain provides complete 4-piece sets.

Forge of the Kalpagni Lantern - Fire weakness bonus applies to both kits. Speed bonus benefits both breakpoint requirements. Farm multiple copies with Break Effect% Rope.

Every successful relic drop potentially benefits both characters. Perfect Break Effect/Speed/ATK% pieces work interchangeably.

Support Character Relics

Messenger Traversing Hackerspace - Path of Elixir Seekers, Xianzhou Luofu

  • 2-piece: +6% Speed
  • 4-piece: Advances ally actions by 12% team Speed for one turn

Pioneer Diver of Dead Waters - Path of Dreamdive, Reverie Dreamscape serves supports in both teams. Farm during 30% secondary stamina allocation.

Optimized Farming Route

Daily Farming Checklist

Days 1-12:

  • 60% Power (144 = 3-4 runs) to Path of Cavalier for Iron Cavalry
  • 30% (72 = 1-2 runs) to support character caverns
  • 10% (24) to Simulated Universe planar ornaments

Days 13-20:

  • 50/50 split between Path of Cavalier and Simulated Universe World 3+ once achieving 70% optimal substats on Iron Cavalry

Final Days:

  • Focus Simulated Universe for planar ornaments and support domains
  • Stop character-specific relics at 70% optimal substats

Domain Priority

Path of Cavalier (Penacony Grand Theater) - Priority domain providing both characters' 4-piece sets. Requires Trailblaze Level 40, costs 40 Power per run.

Path of Jabbing Punch (Jarilo-VI) - Backup for Thief of Shooting Meteor if RNG proves exceptionally unfavorable. Iron Cavalry superior except in extreme cases.

Path of Elixir Seekers (Xianzhou Luofu) - Messenger Traversing Hackerspace for supports. Farm during 30% secondary allocation.

Planar Ornament Farming

Simulated Universe World 3+ drops Forge of the Kalpagni Lantern. Prioritize weekly point rewards first, then supplement with focused runs.

Trailblaze Power Management

240 Power cap with 1 per 6 minutes regeneration = 240 daily Power without refreshes = six Cavern runs at 40 Power each.

Power Requirements

70% optimal substats for both characters: 3,000-3,600 Trailblaze Power (75-90 runs) = 12-15 days natural regeneration.

90%+ optimal substats: 5,000+ Power (125+ runs) = 20+ days. Rarely justifies marginal improvement.

Stellar Jade Refreshes

Costs per refresh:

  • 1st: 50 Stellar Jade for 60 Power
  • 2nd: 100 Stellar Jade
  • Continues upward

Free-to-play: Poor value vs. saving for character pulls. 70% optimization achieves through natural stamina.

Spenders: Consider 1-2 daily refreshes (150-250 Jade) during final weeks. Accelerates farming ~50%, reducing 15-day timelines to 10 days.

Refresh Value Analysis

50 Stellar Jade (first refresh) = 60 Power = 1.5 runs = 3 relics average vs. 50 Jade toward pulls (160 per pull).

Refreshes make sense when:

  • Within 3-5 days of banner without complete builds
  • Secured sufficient Jade for planned pulls
  • Targeting multiple copies requiring excess currency

Avoid refreshes when:

  • 10+ days from banner with natural stamina meeting needs
  • Jade reserves barely cover planned pulls
  • Free-to-play maximizing pull count

Common Pre-Farming Mistakes

Farming One Character First

Don't farm complete sets for one character before starting the second. Since both share identical requirements, farm simultaneously—every optimal piece benefits either character.

Stop when both reach 70% optimal substats. Provides two functional characters faster than perfecting one.

Ignoring Support Relics

Super Break teams require specific support sets. Messenger Traversing Hackerspace for action advance and speed-tuned harmony characters directly impact performance.

Allocate 30% stamina to support domains from day one. Complete teams outperform perfectly-built damage dealers with undergeared supports.

Over-Farming Wrong Main Stats

Don't continue farming after obtaining correct main stats with suboptimal substats. 70% rule exists because improvement beyond requires exponentially more runs for marginal gains.

Break Effect% Rope with Speed and ATK% substats at 70% optimization outperforms farming for 90%. Use saved Power for supports, ascension materials, or trace materials.

Team Composition Impact

The Dahlia Teammates

Pairs with Break Effect enablers and action advance supports. These require Speed-focused builds with Messenger Traversing Hackerspace 4-piece for action manipulation.

Farm support relics during 30% secondary allocation. Prioritize Speed main stat Feet and Speed substats. Support investment multiplies damage through break windows and action economy.

Firefly Teams

Mirror The Dahlia's support requirements with Break Effect enablers and sustain. Identical team structure means support relics transfer directly between compositions.

Support overlap creates exceptional efficiency—one set of support relics services both damage dealers.

Memory of Chaos Planning

Endgame requires two complete teams for dual-team format. Farm duplicate support sets when both teams require identical supports, or build complementary rosters eliminating relic swapping.

Resource Planning Beyond Relics

Stellar Jade Requirements

Soft pity at 75 pulls, hard pity at 90 pulls per 5-star. Budget 160-180 pulls per character accounting for 50/50 losses = 320-360 pulls total (51,200-57,600 Stellar Jade).

22-day banner period provides limited earning. Calculate current reserves plus projected earnings from dailies, events, and version content.

Credit and Enhancement Materials

Budget ~500,000 Credits per character for relic enhancement plus trace upgrades. Farm credit content during non-relic farming days.

Maintain 200+ purple enhancement materials and 50+ gold materials for immediate building at banner launch.

FAQ

What are the best relic sets for The Dahlia in HSR 3.8?

Iron Cavalry Against the Scourge 4-piece (Path of Cavalier, Penacony) and Forge of the Kalpagni Lantern 2-piece (Simulated Universe World 3+). Target 360%+ Break Effect with Body ATK%, Feet Speed, Sphere Fire DMG%/ATK%, Rope Break Effect%. Substats: Break Effect > Speed > ATK%.

Do The Dahlia and Firefly share relic sets?

Yes, identical sets: Iron Cavalry 4-piece and Forge 2-piece with matching main stats and 360%+ Break Effect targets. Every optimal piece benefits either character, maximizing Trailblaze Power investment.

How much Trailblaze Power needed for both characters?

3,000-3,600 Power (75-90 runs at 40 each) for 70% optimal substats = 12-15 days natural regeneration. Stop at 70%—further farming yields diminishing returns.

Farm cavern relics or planar ornaments first?

Use 60/30/10 rule: 60% to Path of Cavalier for Iron Cavalry, 30% to support domains, 10% to Simulated Universe for Forge. Shift to 50/50 caverns/planar once achieving 70% optimal Iron Cavalry substats.

What are Firefly's stat breakpoints?

360%+ Break Effect, 2600+ ATK, Speed at 150 base or 155 (164 with buffs). 150 for standard compositions, 155 for advanced optimizations. Calculate Speed including Forge's +6% bonus and Feet Speed main stat.

Worth refreshing stamina to pre-farm relics?

Free-to-play: Poor value vs. saving Jade for pulls. Spenders: Consider 1-2 daily refreshes (150-250 Jade) during final weeks if you've secured sufficient Jade for planned pulls and are within 3-5 days of banner launch.
