Best Light Cone

Back to All Characters

Firefly, one of the most anticipated units in Honkai: Star Rail, stands out as a new Fire unit on the path of Destruction, specializing in AoE DPS. Her ability to deplete enemy Toughness while applying Fire Weakness, along with her unique SAM appearance and animation in battle, and her powerful Super Breaks, make her a fan favorite. Her significant role in the Penacony story further elevates her popularity.

Honkai: Star Rail - How to Find and Solve Big Ticker Puzzle

The Big Ticker is an alternate yet important encounter in the Seabiscuit quest. Here is how you can solve its puzzle in Honkai: Star Rail.

When it comes to light cones, Firefly's options are somewhat more limited due to her reliance on Break Effect scaling and her unique Super Break mechanic. Since these are not that readily available however, Light Cones that generally increase her DMG by providing some stats, or otherwise even have synergy with HP drain can become quite useful. Luckily, players will still have access to 4-star and some F2P options to equip her with.

7 Flames Afar

When the wearer's cumulative HP loss during one attack exceeds 25% of their Max HP, or if the amount of their own HP consumed at one time is greater than 25% of their Max HP, immediately heals the wearer for 15% of their Max HP, and at the same time, increases the DMG they deal by 50% for 2 turn(s). This effect can only be triggered once every 3 turn(s).

While players may consider Flames Afar due to its F2P availability and SAM artwork, it is actually one of the worst options for Firefly despite its synergy with the HP loss mechanic, unlike being a great option for Blade. This is because Firefly's Super Break doesn't benefit from the increased damage, making half of the effect less useful for her. Nevertheless, if players lack access to other 4-star or 5-star options, it can still suffice.

6 The Moles Welcome You

When the wearer uses Basic ATK, Skill, or Ultimate to attack enemies, the wearer gains one stack of Mischievous. Each stack increases the wearer's ATK by 12%.

Among most other 4-star options, The Moles Welcome You is one of the best options, only surpassed by Indelible Promise, as Firefly can still make use of the ATK stat. However other options like Nowhere to Run, Secret Vow, Under the Blue Sky still perform quite similarly, and as such, if players have access to higher refinements of these options, they can still consider them instead of The Moles Welcome You.

5 Brighter Than The Sun

Increases the wearer's CRIT Rate by 18%. When the wearer uses Basic ATK, they will gain one stack of Dragon's Call for 2 turns. Each stack of Dragon's Call increases the wearer's ATK by 18% and Energy Regeneration Rate by 6%. Dragon's Call can be stacked up to 2 times.

Despite being Dan Heng Imbibitor Lunae's light cone, Brighter Than The Sun is one of the higher-performing 5-star options for Firefly, surpassing choices like Something Irreplaceable or The Unreachable Side, as well as an unrefined On the Fall of an Aeon. The ATK boost and Energy Regeneration it provides can be particularly useful for Firefly. However, its synergy is still not the most optimal, so players should consider equipping it only if they do not have access to the above options.

4 I Shall Be My Own Sword

S1 Passive

Increases the wearer's CRIT DMG by 20%. When an ally (excluding the wearer) gets attacked or loses HP, the wearer gains 1 stack of Eclipse, up to a max of 3 stack(s). Each stack of Eclipse increases the DMG of the wearer's next attack by 14.0%. When 3 stack(s) are reached, additionally enables that attack to ignore 12% of the enemy's DEF. This effect will be removed after the wearer uses an attack.

Jingliu's signature light cone, I Shall Be My Own Sword, also performs well with Firefly, offering performance similar to Brighter Than The Sun. Ignoring enemy defense is a particularly strong effect, and when combined with the ATK buff provided by this light cone, it makes for a powerful combination. As such, I Shall Be My Own Sword is the most optimal other-character signature light cone players can equip for Firefly, even though there are better-suited options available.

3 On the Fall of an Aeon

Whenever the wearer attacks, their ATK is increased by 16% in this battle, up to 4 time(s). When the wearer inflicts Weakness Break on enemies, the wearer's DMG increases by 24% for 2 turn(s).

On the Fall of an Aeon is undoubtedly the best F2P light cone for Firefly, thanks to its ability to increase her ATK and its somewhat synergy with Weakness Break, which Firefly focuses on. Given this, players who have access to this light cone and are not using it on any other character should definitely consider it for Firefly if they are looking for a F2P option.

2 Indelible Promise

Increases the wearer's Break Effect by 56%. When the wearer uses their Ultimate, increases their CRIT Rate by 30%, lasting for 2 turn(s).

While it is a 4-star light cone, Indelible Promise is actually one of Firefly's best options due to its high Break Effect stat, especially when max superimposed, making it comparable to her signature light cone's Break Effect stat. Even without max superimposition, it can provide a damage output comparable to a max superimposed On the Fall of An Aeon. This makes Indelible Promise an excellent choice for players who are not interested in pulling for Firefly's signature light cone.

1 Whereabouts Should Dreams Rest

S1 Passive

Increases the wearer's Break Effect by 60%. When the wearer deals Break DMG to an enemy target, inflicts Routed on the enemy, lasting for 2 turn(s). Targets afflicted with Routed receive 24% increased Break DMG from the wearer, and their SPD is lowered by 20%.

Being Firefly's signature light cone, Whereabouts Should Dreams Rest stands out as the optimal choice for her. It not only boosts her Break Effect but also enhances the damage she deals with Break DMG while debuffing enemies' speed whenever they are dealt Break DMG. For players aiming to fully optimize Firefly, choosing her signature light cone is a niche but excellent decision.
