Honkai: Star Rail Dahlia Best Build: Relics, Light Cones, and Teams

Hello, Trailblazers! 𝐃𝐀𝐇𝐋𝐈𝐀’s coming soon, she is the new 5-star Nihility support, her kit converts the team’s damage into Super Break DMG, amplifying her and her allies’ damage thanks to enemy DEF reductions and applying some buffs.
In this blog, we’ll focus on how to build 𝐃𝐀𝐇𝐋𝐈𝐀, covering her relics, light cones, and team recommendations. This will be a guide like none that has come before. Let’s get started!

‿̩͙‿ ༺ ♰ ༻ ‿̩͙‿

OVERVIEW KIT

✧ SKILL

Creates a field where all enemies receive Fire DMG, Weakness Break Efficiency is increased by 50%, and damage is converted to Super Break DMG.

This “zone” lasts 3 turns and is reduced by 1 each of The Dahlia’s turns.

✧ ULTIMATE

Deals AoE damage and applies “Wilt” to enemies that lasts for 4 turns.

Enemies with Wilt have their DEF reduced and gain an additional weakness of the same type as The Dahlia’s “Dance Partner.”

TALENT

  • Gains 35 Energy when entering the field,
  • Applies “Dance Partner” to the teammate who starts the battle.
  • (If there are no Dance Partners, apply it to the one with the highest Break Effect.)
  • Allows the team to do 1 instance of Super Break DMG when a Weakness is broken.
  • She does a Follow-Up attack when a Dance Partner hits an enemy.
  • (1 Follow-Up per turn, which is saved for the next wave if an enemy is defeated before The Dahlia’s turn.)

✧ TECHNIQUE

Creates a special dimension lasting 20 seconds.

Enemies in this dimension do not attack allies.

When entering combat, The Dahlia immediately applies the “Zone” (the skill’s Zone).

Only one dimension can exist.

✧ BONUS ABILITY 1

When an ally applies Weakness to an enemy, their SPD is increased by 30% for 2 turns.

If a Fire ally applies Weakness with an attack, they inflict 20 Fire Resistance reduction to each target with the added Weakness (after attacking). They also regenerate 10% of their energy, up to a maximum of 50%.

✧ BONUS ABILITY 2

Increases team Break by 24% when entering combat, plus an additional 50% for one turn.

This effect can be triggered again for a duration of 3 turns when The Dahlia receives a shield or healing, but cannot be triggered repeatedly in the same turn.

✧ BONUS ABILITY 3

When she uses her follow app, she recovers 1 point skill. This effect can be triggered 1 time for every 2 follow ups used

The Dahlia Team Compositions

Due to how The Dahlia’s kit works, she excels in Break-focused teams, particularly those featuring high Break Effect DPS characters. Her Zone enables Super Break damage before enemies are broken, making her ideal for teams that rely on Toughness reduction.

Firefly Teams

Firefly is The Dahlia’s ideal partner, as The Dahlia’s passive is designed around Fire-type Break DPS characters. The combination of Firefly’s high Fire Toughness damage and The Dahlia’s Zone creates one of the strongest Super Break teams in the game. Fugue provides additional Break Effect support and Exo-Toughness for the premium setup, while Ruan Mei offers team-wide buffs and Break Efficiency. For F2P players, Harmony Trailblazer (HMC) provides Super Break enabling and works excellently with The Dahlia. Lingsha is the preferred sustain for her additional Break Effect and healing, while Gallagher offers budget-friendly sustain with Break capabilities.

2. Rappa Teams

Rappa benefits significantly from The Dahlia’s Super Break conversion mechanics, as her kit revolves around dealing massive Imaginary Toughness damage through her enhanced Basic ATKs. The Dahlia’s Zone allows Rappa to convert her Toughness reduction into immediate damage even before enemies are broken, increasing her damage output. Fugue’s Exo-Toughness synergizes perfectly with Rappa’s multi-hit attacks, while Ruan Mei provides Break Efficiency and Weakness Break extension. Lingsha or Gallagher complete the team with sustain and additional Break support.

3. Boothill Teams

Boothill’s single-target Break damage pairs well with The Dahlia’s Zone and Defense reduction from her Ultimate. The Dahlia’s ability to apply elemental weaknesses through her Ultimate helps Boothill trigger Weakness Breaks more consistently, especially against enemies that don’t have Physical weakness naturally. Fugue provides additional Break Effect and Exo-Toughness to amplify Boothill’s Break damage, while Ruan Mei offers team-wide buffs. Any sustain unit works, though Lingsha and Gallagher are preferred for their Break Effect contributions.

CONCLUSION

The Dahlia presents itself as a good support for any team that benefits from Super Break damage.

Thanks to the zone she creates, her buffs, debuffs, and follow-up attacks, she provides strategic value by ensuring consistent breaks and damage.
