Dahlia's Kit Meets Firefly's Firepower
Picture Dahlia at Lv80 (ATK 679/DEF 606/HP 1086/SPD 96/Energy 130). Her Skill drops a 3-turn Withering Garden—160% ATK Fire DMG plus 50% ally Break Eff boost, all feeding into Super Break DMG debuffs.
Talent locks onto your highest BE ally (that's Firefly): 35 Energy on entry, 60% Super Break conversion, and 5x 30% ATK FUAs at 200% Super Break/turn.
Firefly at Lv80 (same stats) thrives under Dahlia's Ult: +100% action advance, +60 SPD, +50% BE Eff, +20% enemy Break DMG taken, and 10% Energy from Fire breaks (50% cap). Enhanced Skill? Implants 2-turn Fire Weakness and Combustion (150 SPD to 210; sweet spot at 165 SPD).
Rotation flows like this: Dahlia Skill (Zone up) → Firefly Ult → Fugue FUAs/Super Breaks.
Traces prioritize +37.3% BE/+18% Effect RES/+10% HP; A2 adds 24-50% BE (1 turn); Technique gives a 20s Zone (+60% Super Break). Order: Skill=Talent>Ult>Basic.
(Editor's aside: This synergy? It's chef's kiss for PF—Dahlia turns Firefly into a Break monster.)
Break Effect Breakpoints That Actually Win
Chase 360%+ BE total, 145+ SPD minimum. Why? It smokes SPD>145 setups in 5-cycle/one-wave clears, thanks to Iron Cavalry's DEF ignore.
Key breakpoints: 150% BE (10% DEF ignore), 250% (15-25%), 360%+ caps Talia at 145 SPD.
Super Break math: Firefly gets (0.2×BE+200%) ATK + (0.1×BE+100%) adjacent (360% cap); Module β hits 35%/50% at 200%/360% BE. Dahlia amps it with Zone +50% Eff, Talent's 60% conversion +5x 200% FUAs/turn.
Build smart:
Relics/LC: Stack 360%+ BE in combat (BE>SPD>ATK%>HP subs).
Firefly traces: Ult>Talent>Skill=Basic; sustain that 50% Super Break.

Relics and Planars for Break Dominance
Iron Cavalry 4pc rules (2pc +16% BE; 10% DEF ignore at 150%+, 15-25% at 250%+). Farm Caverns of Jabbing Punch W5-6 (20+ pcs). Mains: Body ATK%, Feet SPD, Sphere ATK%, Rope BE.
Alts? Thief 4pc (+16% BE/+3 Energy Break); Watchmaker 4pc (+30% team BE post-Ult, 2 turns).
Planars shine with Forge of Kalpagni Lantern 2pc (+6% SPD/+40% BE vs Fire-weak, 1 turn); Talia Kingdom 2pc (+16-36% BE at 145+ SPD). Firefly? Iron Cavalry 4pc + Forge; hit 360% BE/165 SPD.
Grind plan: Iron Cavalry>Thief>Watchmaker; subs BE>SPD>HP.
Pre-farm these 6 weeks: Wk1-2 snag 100+ Tatters (dailies/SimUniv/Omni-synth); Wk3-4 Shadows + Echo of War; Wk5-6 relics/ores. Daily 90 TB (30/run x3 Shadows); weekly 3 Echo of War.

Teams and Rotations That One-Shot Waves
Core squad: Dahlia/Firefly/Fugue/Lingsha (or Gallagher/H.TB) for pure one-wave destruction. Heat variant: Firefly+Dahlia+Fugue+Lingsha. F2P flex: Firefly+Dahlia+H.TB+Gallagher. Alt: Boothill+Dahlia+Ruan Mei+TB (Boothill Skill 220% ATK Phys 2-turn Standoff, +50% Toughness Red, 35-170% Break DMG).
Rotation: Dahlia Technique/Zone > Firefly Ult > Enhanced Skill (E1 15% DEF ignore, SP-free). Dahlia Ult blasts 300% ATK AoE Fire +4-turn Wilt (-18% DEF, implants weaknesses).
Break it down:
Dahlia Skill/Ult (Zone/Wilt).
Firefly Ult + Enhanced Skill (360% BE).
Fugue FUAs + sustain; loop Super Breaks.
Build priority: Firefly/Dahlia > Fugue/TB > Lingsha.
(Quick take: Fugue's the glue—underrated for these loops.)
Eidolons, LCs, and Smart Pull Priorities
Dahlia Eidolons: E0 + Sig LC > E2 (+20% BE/field +1 turn) > E6 (+150% BE Dance/+20% FUA advance) > E1 (Ult -20% DEF ignore) > E4 (+5 FUA hits/+12% DMG taken). Sig LC Never Forget Her Flame Lv80 (ATK 529/HP 1164/DEF 463; +60-120% BE/+32-72% Break DMG self/highest BE, 1 SP refund Break). Alts: Whereabouts (+60% BE/+24% Break DMG); Resolution Shines (60-100% Ensnare/-12-16% DEF).
Firefly: E1/E2 (extra turns); E6 +20% Fire RES PEN. Sig LC > most Eidolons; E1 spikes Super Break.
Pull plan: E0 Dahlia + Sig (Phase 1); chars > LCs.
Skip Eidolons if you're risking <360% BE or SP drains.
