Dahlia hits NA servers Dec 16, 2025, 10:00 PM UTC-5, Phase 1 through Jan 6, 2026. We're talking peak Firefly-Fugue optimization: chase 360%+ Break Effect ahead of Speed over 145, Iron Cavalry 4pc locked in. Full stats on relics, teams, traces, Eidolons, pre-farm, rotations—all tuned for max Super Break damage in 3.8. Benchmarks? +50% BE Efficiency, straight DEF ignore.
Why Dahlia Dominates Firefly-Fugue Teams in 3.8
Ever wonder why some supports just click with hypercarries like Firefly? Dahlia's the answer right now. Her 3-turn Withering Garden cranks up team Break Effect and efficiency. It flips debuffs into Super Break DMG, her Ultimate shreds 18% enemy DEF for 4 turns, and yeah, it implants weaknesses too. Skill drops a Zone: 160% ATK Fire DMG plus 50% ally Weakness Break Efficiency, turning Toughness Reduction straight into Super Break. Talent? Hands Firefly a Dance Partner—35 Energy regen on entry, 60% Super Break conversion on broken foes, and 5x 30% ATK FUAs (Follow-Up Attacks) at 200% Super Break per turn.
Firefly's Ult piles on: +100% action advance, +60 SPD, +50% BE Efficiency, +20% enemy Break DMG taken, 10% Energy from Fire Weakness breaks (capped at 50%). Lv80 base stats: ATK 679, DEF 606, HP 1086, SPD 96, Energy 130. That Zone stacks multiplicatively with Firefly's buffs—boom, 5-cycle clears. F2P folks, save 14,400 Jade for the guarantee (114 pulls +25 Special Passes). Go E0 with her Sig LC first.
(Quick aside: I've theorycrafted dozens of these teams—Dahlia feels like she was made for Fugue-Firefly shredfests.)
Super Break Mechanics Crash Course
Super Break DMG scales straight-up linear with BE. Iron Cavalry 4pc kicks in 10% DEF ignore at 150%+ BE, ramps to 15-25% at 250%+. Dahlia makes it happen through Zone conversion and Fugue's Toughness accel. Key benchmarks: Zone's +50% BE Efficiency, Talent's 60% Super Break conversion, those 5x FUAs at 200% Super Break. Farm Caverns of Jabbing Punch for Iron Cavalry. Truth is, 360%+ BE laps Speed builds every time.

Core Build Breakdown
Top Light Cone: Never Forget Her Flame Deep Dive
Her signature 5★ LC? +60-120% BE, +32-72% Break DMG at battle start for herself and the highest BE ally. Weakness Break applies? Refunds 1 SP—resets Ult economy. Lv80: ATK 529, HP 1164, DEF 463. Priority: E0 + Sig > E2 > E6 > E1 > E4. Keeps Firefly-Fugue humming with SP sustain.
Alternatives like Whereabouts Should Dreams Rest (+60% BE, +24% Break DMG) or Resolution Shines (60-100% Ensnare, DEF -12-16%) work in a pinch. How to: 1. Slap on Sig for that 360% BE ramp. 2. Farm 20 Tatters/Fragments/14 Shards. 3. Run rotations, watch SP refunds flow.
Relic Sets: Iron Cavalry Edges Out the Rest
Iron Cavalry 4pc delivers +16% BE (2pc) and DEF ignore that scales with BE thresholds—god-tier for 360% BE Firefly squads. Thief 4pc matches +16% BE with +3 Energy on Break for draggy fights. Watchmaker 4pc pumps +30% team BE post-Ult for 2-turn bursts. At 250% BE, Iron Cavalry ignores 15-25% on Super Break DEF.
Get it done: 1. Grind Iron Cavalry 4pc. 2. Mix in Thief if Energy's tight. 3. Reroll those BE subs like your life depends on it.
Planar Ornaments Ranked
Forge of Kalpagni Lantern 2pc: +6% SPD, +40% BE against Fire-weak foes (1 turn). Talia Kingdom 2pc: +16-36% BE once you hit 145+ SPD. Nail 145 SPD to trigger Talia, then stack BE heavy.
Build path: 1. Mains—Body ATK%, Feet SPD, Sphere ATK%, Rope BE. 2. Subs: BE > SPD > ATK% > HP. 3. Confirm 360%+ BE total.
Break Effect vs Speed: The Hard Math
How Super Break Damage Formulas Shake Out
Super Break loves BE linearly—stack to 360%+ over SPD >145, since raw damage trumps turn speed in 5-cycle clears. Iron Cavalry: 10% DEF ignore at 150% BE, max 25% at 250%+. Dahlia's Zone amps +50% BE Efficiency on top. Math checks out: 360% BE smokes SPD; Talia adds 16-36% BE after 145 SPD. Firefly's Ult tacks +60 SPD anyway.
Steps: 1. Tally base BE from relics/LC. 2. Sub up to 360%+. 3. Cap SPD at 145+ for sync.
3.8 Meta Breakpoints
Hit 145 SPD? Talia activates, balances turns and BE. 250% BE unlocks 15% Super Break DEF ignore. 360%+ BE? Optimal territory vs 145 SPD Firefly-Fugue.
BE Threshold | DEF Ignore (Iron Cavalry) | SPD Requirement
---|---|---
150%+ | 10% | None
250%+ | 15-25% | None
360%+ | Max scaling | 145+ Talia
Data shows higher BE wins; Firefly Ult's +60 SPD covers the rest. (Editor note: Simulated this in planners—BE pulls ahead 20-30% in sustained DPS.)
Real Scenarios: MoC and Pure Fiction
MoC loves Dahlia's +50% Eff and conversion for quicker clears than SPD spam. Pure Fiction? BE shreds Toughness faster. Benchmark: Full Fire team with 5x 200% Super Break FUAs. Simulate in planners: 360% BE + 145 SPD nails 3.8 clears.
