The Dahlia (Constance) is a 5★ Fire Nihility support built around Break Effect and Super Break. Her base kit already transforms break teams by letting allies deal Super Break damage before enemies are fully Weakness Broken, while also providing Weakness Break Efficiency, DEF reduction, and elemental implants.
Eidolons push that further, but their impact and cost efficiency differ a lot. Some are transformative for endgame break teams, others are minor bonuses or simple level bumps.
Overall ranking of The Dahlia’s Eidolons
The table below focuses on Eidolons that change how teams play, rather than simple level increases. E3 and E5 are noted separately because they only raise trace levels.
| Rank | Eidolon | Key effect | Pull priority |
|---|---|---|---|
| 1 | E2 – Fresh, Ethereal, and Beloved | Universal -20% All-Type RES for enemies and automatic Wilt on entry. | Best overall Eidolon; ideal stopping point for spenders. |
| 2 | E6 – And Yet, Always, Deathly Beautiful | Huge Break Effect buff and action advance for Dance Partners. | Premium luxury upgrade after E2 (and signature cone) for heavy spenders. |
| 3 | E1 – When a Bud Readies to Bloom | Spreads her Talent’s Super Break bonus to the whole team and adds a one-time fixed Toughness chunk. | Situational; good in some matchups, but generally weaker than her signature light cone or E2. |
| 4 | E4 – Pity Its Heart Gnawed by Worms | More Talent follow-up hits and a small teamwide damage amp after each follow-up. | Lowest-impact functional Eidolon; mainly for collectors going to E6 anyway. |
| – | E3 – Pity Its Petals Thin as Mist | Raises Ultimate and Basic ATK levels. | Filler along the way; not worth targeting on its own. |
| – | E5 – Fallen, Decayed, and Despised | Raises Skill and Talent levels. | Also filler, though slightly more useful than E3. |
Ranking is driven by how much each Eidolon increases real-world clear speed and comfort in modes like Memory of Chaos, Pure Fiction, and Apocalyptic Shadow, relative to the cost in Stellar Jade or Star Rail Special Passes.
Filler Eidolons: E3 and E5
E3 – Pity Its Petals Thin as Mist. This Eidolon raises The Dahlia’s Ultimate by 2 levels and Basic ATK by 1. Extra Ultimate scaling is welcome because her Ultimate both damages and applies Wilt (DEF reduction plus weakness implants), but the improvement is incremental. Basic ATK scaling matters very little on a support who uses Basics mainly for Skill Point management.
E5 – Fallen, Decayed, and Despised. This one raises her Skill and Talent levels by 2. That does buff her zone damage and the Super Break multipliers on her Talent follow-ups, so it is more relevant than E3. Even so, it still functions as a stat bump; it does not unlock new mechanics or change team rotations.
Neither E3 nor E5 should be direct pull targets. Treat them as incidental upgrades on the way to E4 or E6 if you are already committed to going deep.
Rank 4 – E4 “Pity Its Heart Gnawed by Worms”
E4 modifies her Talent’s follow-up attack. The Dahlia normally launches a multi-hit follow-up whenever the non-self Dance Partner attacks; these hits deal Fire damage and, on broken targets, convert their Toughness reduction into strong Super Break instances.
With E4:
- The number of hits on her Talent follow-up is increased, making that follow-up a denser packet of damage and Super Break.
- After the follow-up resolves, all enemies take increased damage from all sources for a short duration.
This has a few concrete benefits. The Dahlia’s personal contribution to damage and Toughness shredding goes up, and the temporary “take more damage” debuff slightly amplifies her entire team. In long fights where she triggers many follow-ups, this adds up to a noticeable, but not dramatic, improvement.
However, the effect is still tied to her own follow-up frequency and suffers from diminishing returns compared with bigger break multipliers, DEF reduction, or RES reduction. In practice, E4 rarely changes how many turns a team needs to clear a wave, especially when running powerful carries like Firefly, Rappa, or Boothill with Fugue or Harmony Trailblazer.
Because of that, E4 sits at the bottom of the functional ranking. It is a fine upgrade if you are already aiming for E6, but not a good standalone goal.
Rank 3 – E1 “When a Bud Readies to Bloom”
E1 is attractive on paper because it touches both Super Break damage and Toughness bars.
Its two main effects are:
- The Super Break damage multiplier from her Talent, which normally applies only to the Dance Partners, is extended to the entire team, while the two Dance Partners receive an additional boost on top.
- After a Dance Partner attacks an enemy, that enemy suffers an extra one-time chunk of fixed Toughness damage equal to a percentage of its maximum Toughness, with a floor and cap per target and a per-target trigger limit that resets when the enemy dies and reappears in a new phase.
The first part effectively means every ally’s attacks benefit from a Super Break bonus when they hit broken targets, and the main carry and The Dahlia gain an even higher multiplier. The second part is designed to shave turns off high-Toughness enemies in content like Apocalyptic Shadow, where depleting bars quickly is a major part of the challenge.
In practice, several factors keep E1 in third place:
- The Dahlia’s base kit already lets teams deal Super Break damage before enemies are Weakness Broken, and she has substantial Toughness damage and additional fixed Toughness from her traces. Once break teams are properly invested, the extra fixed Toughness from E1 often does not change the number of actions required to break a boss.
- For heavily invested Firefly teams (for example, Firefly E2 and Fugue eidolons), tests show E1 can translate into only a small real-world damage increase in Memory of Chaos, because bosses already break in very few actions.
- The Super Break multiplier extension is strong in isolation, but competes directly with her signature light cone, which offers a very large Break DMG bonus to both her and the main DPS and tends to provide more consistent value for the same or fewer pulls.
That said, E1 is not useless. It performs better:
- Against bosses with unusually thick Toughness bars, especially in Apocalyptic Shadow.
- In teams where not everyone is a dedicated break unit, so extending the Super Break multiplier to the whole squad raises more of the team’s damage.
- With carries like Boothill or Rappa in some Pure Fiction or multi-phase fights where extra fixed Toughness can line up with phase transitions.
Even with those upsides, E1 is generally a lower priority than her light cone or E2 for most accounts. For players caring about pull efficiency, E0 or E0S1 with no Eidolons, or jumping straight to E2, is usually a better plan than stopping at E1.
Rank 2 – E6 “And Yet, Always, Deathly Beautiful”
E6 is The Dahlia’s capstone and, as expected for a sixth Eidolon, is extremely powerful, both numerically and mechanically.
It adds two big effects:
- All Dance Partners gain a massive flat Break Effect bonus. Because Break Effect directly scales both Super Break and traditional Break damage, this dramatically boosts the output of break carries such as Firefly, Boothill, Rappa, and break-styled Xueyi or Himeko.
- Every time The Dahlia’s Talent follow-up triggers, all Dance Partners have their next action advanced, effectively pulling their next turn forward by a significant amount in the turn order.
The Break Effect bonus is straightforward: it makes your main break DPS hit much harder in every mode. The action advance is more subtle but just as impactful. It functions as a recurring tempo tool similar in feel to Harmony light cones like “Dance! Dance! Dance!”, letting core damage dealers act more often per cycle and compressing kill windows.
In sustained content like Memory of Chaos, E6 turns The Dahlia into an enormous damage amplifier and speed engine for the entire break core. In Pure Fiction, accelerating AoE carries such as Rappa or Himeko while also increasing their Break Effect lets them clear waves faster and stack follow-ups more aggressively.
The main reason E6 is ranked below E2 is cost efficiency. Reaching E6 requires an extreme number of pulls, while E2 already provides a universally strong debuff package that every team benefits from. E6 is best viewed as a luxury upgrade for players who are already satisfied with their account’s overall coverage and want to maximise a favourite break team.
Rank 1 – E2 “Fresh, Ethereal, and Beloved”
E2 is the standout Eidolon in The Dahlia’s kit and the one that offers the strongest blend of raw power and practical value.
It introduces two simple but far-reaching effects:
- As long as The Dahlia remains on the field, all enemies suffer a fixed reduction to All-Type RES. This is a universal damage amplification that benefits every ally, regardless of element or path.
- Whenever an enemy enters the field, they are immediately inflicted with Wilt for several turns, without requiring The Dahlia to use her Ultimate on them first.
Wilt from her Ultimate reduces enemy DEF and implants the weaknesses of both Dance Partners’ elements. E2 effectively makes that package automatic on wave entry: enemies start the fight already suffering DEF reduction and holding Fire weakness plus the carry’s element weakness, even before she spends Energy.
For break teams, this is especially valuable:
- Rappa and Boothill love having their element applied in AoE without needing to manually break or rely on single-target implants.
- Firefly teams gain more consistent DEF reduction and Fire implants across entire waves, which matters in Pure Fiction and multi-wave Memory of Chaos stages.
- Mixed teams with partially non-break characters still benefit from unconditional All-Type RES reduction and DEF shred, which stack multiplicatively with many other buffs.
The constant All-Type RES reduction is useful outside of pure break compositions as well. Since it does not depend on enemies being broken, specific zones being active, or particular triggers firing, it simply raises the baseline damage output of any group that fields The Dahlia.
Because of this broad applicability and the strength of the combined RES and DEF debuffs, E2 is widely considered the best stopping point for anyone investing into her Eidolons. It meaningfully upgrades every team she joins, without the extreme pull cost of E6.
How The Dahlia’s Eidolons compare to her light cone
The Dahlia’s signature Nihility light cone, “Never Forget Her Flame”, is a key part of her vertical scaling. It provides a large Break Effect stat and a substantial Break DMG bonus to both her and one ally, along with some Skill Point restoration on weakness implants. For break-focused teams, this functions as a multiplicative damage boost to the main carry on top of her base kit.
When weighing Eidolons against her cone:
- For most players, E0S1 (no Eidolons, signature light cone at Superimposition 1) is a very strong and cost-efficient endpoint. Her base kit plus the cone already revitalise break carries like Firefly, Boothill, Rappa, and Himeko.
- E0S1 → E2S1 is the next high-value jump. E2 stacks its RES and DEF debuffs with the cone’s Break DMG bonus, giving a large multiplicative increase without needing to chase E1 or E4.
- E1 is generally lower priority than the cone. Its benefits are more niche and matchup dependent, while the cone’s bonuses are consistently active in every battle.
- E6 sits firmly in the luxury category, coming after both S1 and E2 for rational pull value.
Account context matters as well. Players already holding high-investment Firefly or Fugue often see less relative benefit from E1 and even some parts of E4, because their teams are already optimised around rapid Toughness breaks. Those cases push E2 and the signature light cone even further ahead in priority.
Practical pull recommendations
Putting everything together, a simple priority list for most accounts looks like this:
- Baseline: Obtain The Dahlia at E0. Even with a 4★ cone like “Long Road Leads Home” or “Before the Tutorial Mission Starts”, she is already a top-tier break support.
- First upgrade: Aim for her signature cone at S1 if you want to build a long-term break core. It significantly improves both her and the main DPS in any break composition.
- Major Eidolon goal: Go for E2 if you are comfortable investing further. E2’s All-Type RES reduction and automatic Wilt on entry provide a universal, durable upgrade for every team she supports.
- Optional extras: Consider E1 or E4 only if you enjoy optimising specific matchups or are on the way to E6. Reserve E6 for situations where you are consciously choosing to heavily invest into one archetype and one character.
Even at E0, The Dahlia restores much of the relevance of break units in the current environment. Her Eidolons add meaningful power on top, but only E2 and, for enthusiasts, E6 fundamentally change what her teams can do. For anyone watching their Stellar Jade, focusing on E0 or E0S1, then treating E2 as the main milestone, is a balanced and efficient approach.
