Introductions

Welcome to our team composition guide for Firefly in Honkai: Star Rail. In this guide, we'll explore the best teams to build for Firefly, including recommended team compositions, character synergies and everything you need to know to let your Firefly excel.

Best Synergies for Firefly

The Dahlia
The Dahlia

The Dahlia is the new premier Break Support that is designed to work perfectly with Firefly. The Dahlia allows for Superbreak Damage to work at all times even without the enemy being Weakness Broken which fixes the biggest issue with Break Teams. Additionally, Outgrow the Old, Espouse the New works perfectly with Firefly giving her the full benefit, increasing her SPD by 30% at all times and eliminating the downtime from her Ultimate by generating 40-50% Energy for her.

Fugue
Fugue

Fugue is a powerful Super Break Enabling Nihility Support. Fugue debuffs enemies lowering DEF, provides Break Effect to Firefly, and converts toughness damage into Super Break. Fugue's unique mechanic is Exotoughness which allows for enemies to be weakness broken a second time (equal to 40% of max Toughness) and 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. Harmony Trailblazer also does significant Toughness damage against Imaginary monsters which can help enable Super Break faster.

Ruan Mei
Ruan Mei

Ruan Mei is a Harmony Support that gives 50% Weakness Break Efficiency to the entire team. This will allow you to break the enemy quicker and deal more Super Break damage with each hit.

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.

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.

Firefly's Best Teams

Firefly is a potent break DPS however a lot of her strength comes from running the new break support The Dahlia which makes her strong in all content. Firefly is significantly weaker without The Dahlia but break as an archetype is uniquely powerful in Apocalyptic Shadow and she can perform very well there without The Dahlia.

The healer in each team can be swapped out but Lingsha is the best healer for DPS in Break Teams although Gallagher is completely fine and 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.
