Honkai: Star Rail – Firefly build and ascension guide

Come into your own with the best Honkai: Star Rail Firefly build and leave behind a legacy that will forever be remembered. Firefly is a 5-Star character following The Destruction and dealing Fire DMG. She’s another member of the Stellaron Hunters and is an expert at inflicting Break DMG.

Her Skill, Order: Aerial Bombardment, consumes a large chunk of her own HP to deal Fire DMG to a single enemy. This move advances her next action forward and restores a lot of Energy.

Her Talent, Chrysalid Pyronexus, increases Firefly’s Damage Reduction the lower her HP is and dispels all debuffs on her when she reaches maximum Energy.

Firefly’s Ultimate, Fyrefly Type-IV: Complete Combustion, enables her to enter the Complete Combustion state and immediately take another turn. In this state, Firefly’s SPD is increased and she has access to an Enhanced Basic Attack and Enhanced Skill, which both raise her Weakness Break Efficiency and Break DMG when used. One of Firefly’s Traces even allows attacks made during the Complete Combustion state to reduce Toughness regardless of Weakness Type, though with reduced efficiency.

Her Enhanced Attack, Fyrefly Type-IV: Pyrogenic Decimation, restores Firefly’s HP and deals Fire DMG to a single target.

Her Enhanced Skill, Fyrefly Type-IV: Deathstar Overload, restores Firefly’s HP, applies Fire Weakness to a single target for two turns, and deals Fire DMG to that target as well as adjacent enemies based on her ATK and Break Effect.

Firefly’s Eidolons, which can be obtained by pulling copies of her, provide additional power-ups. Eidolon Level 1 allows her Enhanced Skill to partly ignore enemy DEF and not consume Skill Points, Eidolon 2 lets Firefly immediately take another turn if she defeats or inflicts Weakness Break on an enemy during Complete Combustion. Eidolon 4 increases her Effect RES during Complete Combustion. Finally, Eidolon 6 buffs her Fire RES PEN during Complete Combustion and increases the Weakness Break Efficiency of her Enhanced moves even further.

Honkai: Star Rail – Firefly: best Light Cones

Firefly’s signature Light Cone, Whereabouts Should Dreams Rest, is the premium choice to get her geared up with, providing a massive Break Effect buff. In addition, it inflicts a debuff called Routed upon dealing Break DMG to a target, making them more vulnerable to Break DMG and reducing their SPD for two turns.

Firefly is a powerhouse of the so-called “Break Meta” and her damage mainly scales with Break Effect, so this will be the crucial stat to keep an eye on. One of her Traces provides Break Effect based on her ATK as well, so you can always get more of it by going all-in on ATK.

Best Light Cones for Firefly in HSR:

• Whereabouts Should Dreams Rest (5-Star)
• On the Fall of an Aeon (5-Star)
• Something Irreplaceable (5-Star)
• Indelible Promise (4-Star)
• Nowhere to Run (4-Star)
• The Moles Welcome You (4-Star)
• Flames Afar (4-Star)

Honkai: Star Rail – Firefly: best Relics

Despite being a damage dealer, Firefly doesn’t require you to seek pieces with CRIT Rate and CRIT DMG as her main offensive power comes from Break DMG – you want Break Effect, ATK, and SPD (this is important to allow her as many Enhanced Skill uses as possible before Complete Combustion runs out) to maximize her effectiveness on the battlefield. 

You can fill any gaps in the stats with defensive attributes like HP % or Effect RES, which help Firefly’s durability.

Best Relic Sets for Firefly in HSR:

• Iron Cavalry Against the Scourge (4) – +16% Break Effect, wearer’s Break DMG ignores 10% of enemy DEF when their Break Effect surpasses 150% and additionally allows their Super Break DMG to ignore 15% of enemy DEF when their Break Effect surpasses 250%.
• Thief of Shooting Meteor (4) – +16% Break Effect, +16% Break Effect and regenerates three Energy when the wearer inflicts Weakness Break on an enemy.

• Talia: Kingdom of Banditry (2) – +16% Break Effect, +20% Break Effect when SPD is 145 or higher.

Best stats for Firefly in HSR:

Honkai: Star Rail – Firefly: best teams

Firefly really kicked the “Break Meta” into overdrive, being a fantastic damage dealer scaling with Break Effect and coming with the ability to inflict Super Break DMG.

• Firefly (Main DPS), Trailblazer (Harmony) (Support), Ruan Mei (Support), Gallagher (Support)

This is the best team you can build around Firefly. Trailblazer (Harmony) should always be at Firefly’s side and allows the entire party to deal Super Break DMG to enemies suffering from Weakness Break, contributing tons of DPS themselves in this way. Fugue is a fantastic option for replacing Trailblazer, though, filling a similar role on the team.

Ruan Mei provides more Break Effect, SPD, and Weakness Break Efficiency, not to mention her ability to keep targets Weakness Broken for longer to allow for more Super Break goodness. Bronya, Asta, and Tingyun are excellent substitutes for Ruan Mei. They may not provide any Break-specific boons, but offer bonus ATK and benefits like SPD and Energy Regeneration. Fugue is another excellent addition to the team, allowing Firefly to trigger a second instance of Weakness Break on enemies for extra Break DMG.

Gallagher can keep the team fresh while also dishing out very respectable Break DMG with his kit, making this team an offensive powerhouse bar none. Lingsha is an excellent alternative to the barkeeper, providing substantial Break DMG and more consistent healing.
