Our guide for The Dahlia features everything we currently know, please note however that The Dahlia is still in beta so aspects of her guide and kit are subject to change.

Best Synergies for The Dahlia

Firefly
Firefly

Firefly is the character who receives the most effect out of Dahlia's A2 Trace Outgrow the Old, Espouse the New as it is designed around Firefly using it. With the addition of The Dahlia, Firefly's best teams are now entirely mono-fire too which makes damage significantly more reliable.

Boothill
Boothill

Boothill is a powerful Break Unit that can apply Physical Weakness which allows him to trigger Dahlia's A2 Trace Outgrow the Old, Espouse the New. As Boothill is is a Physical character he cannot get the full effect out of this talent but the 30% SPD Boost is still very potent. Boothill benefits significantly from being able to trigger Super Break at all times and

Rappa
Rappa

Rappa is a strong Break DPS that deals high damage and gains an incredible DPS boost from being able to deal Super Break DMG at all times but she does not apply Weakness which means she cannot trigger Dahlia's A2 Trace Outgrow the Old, Espouse the New to gain the SPD boost making her synergise worse than other break DPS.

Fugue
Fugue

Fugue is next strongest Super Break support as she offers a large boost to Super Break damage, lowers enemy DEF, provides Break Effect to your main DPS and allows for enemies to be weakness broken a second time (with a toughness bar equal to 40% of max Toughness) which can trigger all break effects an additional time.

Harmony Trailblazer
Harmony Trailblazer

Harmony Trailblazer is a Harmony Support that enables your entire team to deal Super Break Damage. The doubling up of Super Break boosts increases Team DPS significantly. Harmony Trailblazer also does a large amount of Toughness Damage thus doing a very large amount of Super Break when played with Dahlia.

Silver Wolf
Silver Wolf

Silver Wolf is a Nihility debuffer that reduces enemy DEF, All Type RES and implants Weaknesses which all boost the damage of break characters. Additionally, as Silver Wolf implants weaknesses she will get the SPD buff from Dahlia's A2 Trace Outgrow the Old, Espouse the New.

Despite getting the SPD buff Silver Wolf would not normally synergise that well with Dahlia as she does not inherently have very high Toughness damage per turn but with Silver Wolfs Eidolon 1 and the Before the Tutorial Mission Starts Lightcone Silver Wolf can use her ultimate every turn which does a very significant amount of Toughness damage, especially for AoE, each turn. This DPS is further boosted when Silver Wolf runs Eagle of Twilight Line Relic Set as it a huge effective SPD boost.

Ruan Mei
Ruan Mei

Ruan Mei is a Harmony Support that gives 50% Weakness Break Efficiency to the entire team which will boost all Super Break damage being done.

Lingsha
Lingsha

Lingsha is a Abundance Healer who does a large amount of healing and AoE Toughness Damage while applying an increased Break DMG taken debuff to all enemies which synergises well with any break team.

Gallagher
Gallagher

Gallagher is a Abundance Healer who can apply an increased Break DMG taken vulnerability to enemies and does a large amount of Single Target Toughness Damage which can do a lot of boss DPS.

The Dahlia's Best Teams

The Dahlia is an incredibly powerful unit made to support break teams, however she is at her most powerful when supporting Firefly but this does not mean this is her only viable team. The Dahlia is the best support for all Break Teams regardless of their element.

The Sustain Unit used for each team can be swapped out but Lingsha is the best healer for DPS in Break Teams but Gallagher is a fully viable option if you do not have Lingsha and he still does good DPS.

This is not a comprehensive list of teams. The inclusion or exclusion of any given team does not necessarily reflect its power level.
