Firefly is a Fire-element character who follows the Path of Destruction. She is a specialist DPS focused on triggering Super Break Damage through Weakness Breaks. To perform at her best, she requires a team that prioritizes boosting Break Effect. Firefly is a valuable damage dealer due to her ability to inflict Fire Weakness while in her Enhanced Sam state. Additionally, she can ignore the elemental weaknesses of the target’s two adjacent sides, making her highly effective in multi-target situations.

Best Cavern Relics

(2) Increases Break Effect by 16%.
(4) If the wearer's Break Effect is 150% or higher, the Break DMG dealt to the enemy target ignores 10% of their DEF. If the wearer's Break Effect is 250% or higher, the Super Break DMG dealt to the enemy target additionally ignores 15% of their DEF.
This set stands out as Firefly’s best relic option, focusing on Break Effect stats that are entirely beneficial to her damage—especially when triggering Super Break DMG.
(2) Increases Break Effect by 16%.
(4) Increases the wearer's Break Effect by 16%. After the wearer inflicts Weakness Break on an enemy, regenerates 3 Energy.
(2) Increases Break Effect by 16%.
(4) When the wearer uses their Ultimate on an ally, all allies' Break Effect increases by 30% for 2 turn(s). This effect cannot be stacked.
This is a viable alternative if Iron Cavalry Against the Scourge set isn’t available yet, as it provides a straightforward Break Effect boost.

Best Planar Ornaments

(2) Increases the wearer's SPD by 6%. When the wearer hits an enemy target that has Fire Weakness, the wearer's Break Effect increases by 40%, lasting for 1 turn(s).
This Planar Ornament set synergizes perfectly with Firefly, increasing Break Effect by 40% for 1 turn when attacking an enemy with Fire Weakness—providing a strong boost to her overall damage output.

Substats
ATK% / Break Effect / SPD / Effect RES
Super Break DMG doesn’t scale with Fire DMG boosts, making an ATK% Sphere the better choice for this specialized damage type. Firefly also doesn’t rely on Crit stats for her Body relic or substats. Instead, prioritize ATK% and Break Effect—aiming for 180% to 200%, which can double to 360% during battle.

Best Light Cones

SourceLight Cone Event Warp
Metamorphosis
Increases the wearer's Break Effect by 60~100%. 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 24.0~40.0% increased Break DMG from the wearer, and their SPD is lowered by 20%. Effects of the same type cannot be stacked.
This is Firefly’s signature Light Cone, with effects that are perfectly tailored to her kit.
SourceHerta's Store
Moth To Flames
When the wearer attacks, increases their ATK by 8~16% in this battle. This effect can stack up to 4 time(s). After the wearer breaks an enemy's Weakness, increases DMG dealt by 12~24%, lasting for 2 turn(s).
This is a free-to-play Light Cone available from the Herta Shop. It primarily increases ATK and provides a damage boost when inflicting Weakness Break on enemies.
