HSR The Dahlia Light Cones: Best Options for the Break Queen

If you’ve been following the current Break meta, you already know how incredibly strong The Dahlia is. She’s essentially the core support of any Break-focused team, offering steady Break Efficiency and Break DMG buffs. And of course, with a unit this central, her Light Cone choices matter a lot.

Let’s break down her best-in-slot picks, why they work, and what you can use if you’re not planning to pull for her signature.

Best-in-Slot: Never Forget Her Flame (5★)

Stats (Lv. 80): HP 1164 | ATK 529 | DEF 463

The Dahlia’s signature Light Cone is extremely powerful, and honestly, it fits her kit perfectly.

What it does

Immolation:

• Increases Break Effect by 60%–120%.
• At the start of combat, boosts Break DMG for the wearer and the ally who triggered combat by 32%–72%.
• If no ally triggered combat, the bonus goes to The Dahlia + the ally with the highest Break Effect.
• When The Dahlia applies Weakness, she refunds 1 Skill Point (once per Ultimate cycle).
• Same-type buffs don’t stack.

Why it stands out

That 32% Break DMG (S1) buff is one of the rarest multipliers in the game. It’s a huge deal for any Break-focused team. Combine that with the huge Break Effect boost and some SP comfort, and it covers everything The Dahlia needs.

If you’re building around Break teams, this is the ideal pick.

 

5★ Options

Long Road Leads Home (5★)

Stats (Lv. 80): HP 953 | ATK 476 | DEF 662

If you’re looking for a strong 5★ option, Long Road Leads Home is absolutely worth considering. Even though it’s technically Fugue’s signature Light Cone, it fits The Dahlia surprisingly well because it doubles down on exactly what Break teams need: big Break Effect and consistent Break support utility.

Effect (S1):

• Increases Break Effect by 60%.
• When an enemy’s Weakness gets broken, inflicts Charring (100% base chance), increasing Break DMG taken by 18% for 2 turns (up to 2 stacks).

Why it works on The Dahlia

The Break Effect boost is already great, but the real value comes from Charring, which stacks and gives your team a reliable Break DMG increase. Since The Dahlia is constantly helping your team trigger Weakness Breaks, she procs this effect naturally, making it a very comfortable and surprisingly competitive option.

 

4★ Alternatives

Holiday Thermae Escapade (4★)

Stats (Lv. 80): HP 1058 | ATK 529 | DEF 331

Effect:

• Boosts DMG dealt by 16%–32%.
• After hitting an enemy, inflicts Vulnerability (100% base chance), increasing DMG taken by 10%–16% for 2 turns.
• Same-type debuffs don’t stack.

Why it’s the best 4★ choice for The Dahlia

It gives your team a reliable damage increase that doesn’t require a complicated setup and applies Vulnerability to enemies after attacking.

As you know, a lot of players already run Resolution Shines As Pearls of Sweat on Fugue. If The Dahlia equips the same Light Cone, the effect doesn’t stack, meaning you’d get almost no value from it.

Holiday Thermae avoids this problem and gives your team a reliable Vulnerability debuff plus a straightforward damage bump. It’s simple, effective, and works perfectly alongside Fugue.

If The Dahlia and Fugue are in the same team, this is easily her best 4★ option.

Resolution Shines As Pearls of Sweat (4★)

Stats (Lv. 80): HP 953 | ATK 476 | DEF 331

Effect:

• Hitting an enemy can inflict Ensnare (DEF reduction 12%–16%).

When it’s good

It’s good when you just need simple, guaranteed DEF shred to help your team’s Break damage hit harder.

The Catch: If you're pairing The Dahlia with Fugue, chances are your Fugue is already holding this Light Cone.

Before the Tutorial Mission Starts (4★)

Stats (Lv. 80): HP 953 | ATK 476 | DEF 331

Effect:

• Boosts Effect Hit Rate by 20%–40%.
• Attacking DEF-reduced enemies restores 4–8 Energy.

When it’s good

The Dahlia doesn’t desperately need Effect Hit Rate, but the extra Energy is nice for more frequent Ultimates. It’s not a top pick, but if you have a high Superimposition copy lying around, it can feel surprisingly smooth.

 

Final Recommendation

Best option overall:

Never Forget Her Flame (her signature)

Great ★5 alternative:
Long Road Leads Home

Best 4★ option (especially with Fugue):

Holiday Thermae Escapade

Other options:

Besides Resolution Shines As Pearls of Sweat and Before the Tutorial Mission Starts, if you have access to Herta’s Store, Solitary Healing is another solid option. It helps The Dahlia hit important Break Effect breakpoints while giving her a bit of extra energy.

 

Conclusion

The Dahlia gets a lot stronger with the right Light Cone, so picking the one that matches your team can really boost her impact. Whether you’re going all-in on Break teams or building around more accessible options, these recommendations will keep her performing at her best.
