The Dahlia Basic Information

The Dahlia is a 5-star Fire-Type character following the Path of Nihility, positioned as a core support for the Super Break system. Her role can be summarized in one sentence: She allows your Break DPS to consistently output Super Break DMG even when the enemy’s Toughness is not fully depleted. This is a revolutionary design in traditional Break teams, filling the output gap during the shield-break cooldown for DPS characters like Firefly.

The Dahlia’s backstory is deeply linked to Penacony, representing the mysterious entity “Constance,” leading Trailblazers to rediscover the truth behind memories and dreams. Beyond her striking background, her actual combat power was established as a T0 Super Break Support during her debut in version 3.8. The 4.2 rerun offers Firefly players who missed her a chance to complete their strongest team.

Skill Mechanics Analysis

The Dahlia’s core mechanics revolve around the “Co-dancer” and “Field” systems. Understanding these two is key to using her correctly.

Basic ATK: Plucking… Memory’s Fissure Blooms

Deals Fire DMG equal to 100% of The Dahlia’s ATK to a single enemy, with a Toughness Reduction of 10. Basic ATK is not core to her gameplay; prioritize using her Skill to maintain the Field.

Skill: Licking… Betrayal’s Tongue of Flame

The Dahlia’s core skill. Activates a Field for 3 turns. During this effect:

• Allies’ Weakness Break Efficiency increases by 50%
• When enemies are not in the Weakness Broken state, Toughness Reduction can also be converted into Super Break DMG
• Deals Fire DMG equal to 160% of ATK to a single enemy and adjacent targets

This skill is The Dahlia’s biggest selling point: she allows teammates to generate Super Break DMG while reducing the Toughness bar (even before the enemy is broken), solving the output downtime issue of traditional Break teams.

Ultimate: Drowning… Ashes Invite to the Grave (130 Energy)

Inflicts the [Withered] state on all enemies (lasting 4 turns) and deals 300% ATK as Fire DMG (distributed among all enemies). [Withered] state effects:

• Enemy DEF is reduced by 18%
• Enemies are inflicted with Weaknesses of all [Co-dancer] types (allowing Firefly to deal full damage even to non-Fire weak enemies)

Talent: Who’s Afraid of Constance?

The soul of The Dahlia’s kit. Upon entering battle, she regenerates 35 Energy and makes herself and “another ally who starts the battle” [Co-dancers]. [Co-dancer] mechanics:

• When a [Co-dancer] attacks a Weakness Broken enemy, the Toughness Reduction of the attack is converted into 1 instance of 60% Super Break DMG
• After an enemy is attacked by the other [Co-dancer], The Dahlia launches a Follow-up Attack—dealing 5 hits, each dealing 30% ATK as Fire DMG to a random enemy
• Each Follow-up hit on a Weakness Broken enemy converts into 1 instance of 200% Super Break DMG (triggers up to once per turn)

Bonus Abilities (Traces)

The Dahlia’s three major Traces enhance her utility: Another Funeral—Upon entering battle, increases other characters’ Break Effect (equal to 24% of The Dahlia’s Break Effect + 50%) for 1 turn; triggers again when The Dahlia receives healing or a shield (lasts 3 turns). Mourning the Departed—When launching a Talent Follow-up Attack, every 2 hits recovers 1 Skill Point for the team. Discarding the Old, Loving the New—When an ally applies a Weakness, their SPD increases by 30% for 2 turns; Fire-type characters also gain fixed Toughness Reduction and recover 10% Energy (up to 50%), providing extra energy acceleration for Firefly.

Best Light Cone Recommendations

🥇 Top Pick: Forget Her Not’s Flame (Signature)

The Dahlia’s signature Light Cone meets all her needs: Break Effect +60%, and upon entering battle, increases Break DMG by 32% for The Dahlia and the other Co-dancer. It also recovers 1 Skill Point whenever a Weakness is applied. This is the best long-term investment for her.

🥈 F2P & Alternative Options

If the signature is unavailable, consider these (in order of priority): Lies in the Wind → Long Road to Return (Fugue’s signature, good stacking benefits) → Incessant Rain → Resolution Shines As Pearls of Sweat (4-star, but only one per team) → Solitary Healing / Fermata. Nihility Light Cone gaps are generally small for her; investment is better spent on Eidolons.

Best Relic Configuration

4-Piece Set: Iron Cavalry Against Scourge (Highly Recommended)

This is the only recommended set for The Dahlia, as she can boost teammates’ Break DMG based on her own Break Effect. Maximizing her Break Effect yields the highest returns.

Planar Ornaments: Forge of the Kalpagni Lantern

Also the top choice for Planar Ornaments. Since her base HP is low, choosing HP% for the Body and Sphere can improve survivability without affecting output, as her damage doesn’t rely heavily on ATK stats.

Sub-stat Priority

The priority is clear: Break Effect / SPD >> Effect Hit Rate (to ensure Weakness application) > others. Aim for a SPD of 160+ to maintain a proper rhythm with Firefly.

Best Team Comps

🏆 Top Tier: Firefly Break Team

Firefly + The Dahlia + Fugue/Harmony Trailblazer + Sustain (Fu Xuan, Asta, etc.) is currently the strongest Super Break configuration. The logic: Firefly is the main Break DPS, The Dahlia allows Firefly to burst Super Break DMG during Toughness reduction, and Fugue provides Break DMG amplification. A sustain is required to trigger the “Another Funeral” Trace.

🥈 Alternative Options

If you don’t have Firefly, consider Rappa + The Dahlia + Fugue + Sustain. Rappa is a solid secondary Break DPS, though you lose the Fire-specific SPD and Energy buffs. Boothill can also work, but the overall efficiency is lower than the Firefly version.

⚠️ Important: The Dahlia’s team must include a Healer or Shielder to consistently trigger the Break Effect bonus from her “Another Funeral” Trace.

Eidolon Analysis

Investment Advice: E1 is extremely cost-effective, even surpassing some Light Cones. Priority: E1+S0 > E1+S1 > E2+S1. E6 is powerful but not necessary for most players.

Ascension Materials

Total materials needed for Level 80 and Max Traces:

Stat Goals & Trace Priority

• SPD: 160+
• Break Effect: 400%+ (Higher is better)
• Effect Hit Rate: 50%+
• HP: 12,000+ (For survival)

Trace Priority: Talent > Skill > Ultimate > Basic ATK (Keep Basic at Lv. 1). The Talent is the core source of damage and frequency.

4.2 Rerun Pull Advice

✅ Pull if:

• You own Firefly (especially E2+)
• You need the final piece for your Break team
• You love the Super Break playstyle

⚠️ Skip if:

• You don’t have Firefly and don’t plan to build a Break team
• You are focusing on the Remembrance system
• You are saving for Feiying in the second half

Summary

The Dahlia is an indispensable core support for the Super Break system. Her Field skill rewrites the logic of Break teams, making Firefly’s output more continuous and explosive. The 4.2 Anniversary rerun is the perfect time to complete your Break team. Good luck, Trailblazers! May this journey lead us to the stars. ✨
