Firefly was featured in the recent HSR 2.3 Drip Marketing campaign, which almost confirms her for the upcoming HSR 2.3 version. If the HSR 2.2 banners follow the normal cycle, then Honkai Star Rail 2.3 is expected to be released on June 18, 2024. This means that Firefly will be released on either June 18 (first-half banner) or July 8 (second-half banner).

HSR Firefly Path, Element Type, Rarity & Drip Marketing

Honkai Star Rail’s recent Drip Marketing campaign featured Firefly, and it has received an amazing reception from HSR players with 6.9 million views and 121k likes on X (Twitter) at the point of writing. The community is glad that she was featured as Firefly and not Sam.

Firefly is a 5-star DPS Destruction character with the Fire damage type. Her Drip Marketing mentions that she was born as a weapon and is afflicted with Entropy Loss Syndrome due to genetic modification. Firefly joined the Stellaron Hunters in search of the meaning of life and to relentlessly pursue ways to defy fate.

Her Drip Marketing makes it sound as if she was a lab experiment, which is something we haven’t learned in the Trailblazing missions. It would be interesting to learn who or what is responsible for her affliction and how it plays into the grand scheme of things.

HSR Firefly Leaked Kit and Traces

Sam’s kit was leaked some time back and we expect it to be around the same for Firefly. It is also rumored that players will be able to change her into Firefly or Sam in battle with a switch button. Now let’s take a closer look at her leaked kit, but remember that the following information is based on leaks so take it with a pinch of salt.

  • Order: Flare Propulsion (Basic Attack): Deals Fire Damage equal to 100% of Firefly’s Attack to a single target.
  • Firefly Type-IV: Pyrogenic Decimation (Enhanced basic Attack): Restores HP equal to 20% of her Max HP and deals Fire Damage to a single target equal to 250% of her Attack.
  • Order: Aerial Bombardment (Skill): Consumes HP equal to 50% of Firefly’s Max HP and regenerates a fixed amount of energy equal to 50% of her total energy. Deals Fire damage to a single enemy equal to 250% of her Attack.
  • Firefly Type-IV: Deathstar Overload (Enhanced Skill): Restores HP equal to 35% of her Max HP and applies Fire Weakness to a single enemy if it already doesn’t have one for 2 turns. Deals Blast Fire Damage equal to 1xBreak Effect + 400% of Firefly’s Attack to the target enemy, and 0xBreak Effect + 200% of Firefly’s Attack to adjacent targets. The Break Effect added in the calculation is capped at 360%.
  • Firefly Type-IV: Complete Combustion (Ultimate): Enters Complete Combustion state, which 100% advances her action and summons a Countdown Timer on the action bar. The Complete Combustion state changes her Basic Attack and Skill to their Enhanced version. In Complete Combustion state, Firefly’s speed increases by 50, and when she uses the Enhanced Basic Attack or Skill, it increases her Weakness Break Efficiency by 50%, increases the damage received by the weakness broken enemies by 12%, lasting until the current attack ends. The Complete Combustion state of Firefly ends when Cooldown Timer starts in the Action order, which has a fixed speed of 90.

  • Chrysalid Pyronexus (Talent): Reduces damage taken by Firefly the lower her HP is. When her HP is 20% or lower, the damage reduction reaches the maximum level, reducing up to a maximum of 40%. While in the Complete Combustion state, her damage reduction remains at the maximum effect, and her effect resistance becomes 25%. If her energy is lower than 50% at the start of the battle, it regenerates energy to 50%. Once her Energy is regenerated to its maximum, dispels all debuffs on SAM.
  • Order: Meteoric Inceneration (Technique): She leaps into the air and moves without restrictions for 5 seconds. While in the Air, she can plunge attack at a set area. If the duration ends before plunge attacking, she descends and immediately attacks all enemies within a set area. After the battle starts, she applies Fire Weakness to all enemies without one for 2 turns, and then deals Fire damage equal to 200% of Firefly’s attack to all enemies.

Firefly’s leaked kit has been updated and it still suggests very strong DPS and solo sustaining abilities. She can constantly heal herself and deal high amounts of damage to enemies. Her kit also allows her to take multiple turns by buffing her speed and forwarding her action. Firefly is looking to be a very strong DPS character with her early leaks.

Now that you have taken a look at Firefly’s leaked kit and traces, let’s take a closer look at her leaked Eidolons as well.

  • In Reddened Chrysalis, I Once Rest (E1): When using her Enhanced Skill, she ignores 15% of the target’s Defense and the Enhanced Skill doesn’t consume Skill points.
  • From Shattered Sky, I Free Fall (E2): When using the Enhanced Basic ATK or the Enhanced Skill in Complete Combustion state to defeat an enemy target or cause them to be Weakness Broken, Firefly immediately gains 1 extra turn. This effect can trigger again after 1 turn.
  • Amidst Silenced Stars, I Deep Sleep (E3): Skill Level + 2, up to Level 15 max, Basic Attack Level + 1, up to Level 10 max.
  • Upon Lighted Firefly, I Soon Gaze (E4): Firefly is immune to Crowd control debuffs in Complete Combustion state. This effect can only trigger 2 times during each Complete Combustion.
  • From Undreamt Night, I Thence Shine (E5): Ultimate Level + 2, up to Level 15 max, Talent Level + 2, up to Level 15 max.
  • In Finalized Morrow, I Full Bloom (E6): Increases Fire Resistance penetration of Firefly by 12% during Complete Combustion. When using the Enhanced Basic ATK or Enhanced Skill, increases the Weakness Break efficiency by 50%.

Firefly’s updated leaked Eidolons are extremely strong. Her E1 allows her Enhanced Skill to ignore 15% of the defense, which is extremely strong. Furthermore, her E2 is simply broken as it gives her an extra turn when she uses her Enhanced Basic Attack or Skill to defeat or weakness-break an enemy during the Complete Combustion state. Pair her E2 with the insane Speed her build will have, and you can likely see how broken it can be. Her E4 and E6 are also ridiculously strong, and I am assuming they will be nerfed soon.

HSR Firefly Traces and Ascension Abilities

Ascension Abilities:

  • Module α: Antilag Outburst (Ascension 2): While in Complete Combustion state, attacking enemies without Fire Weakness also reduces their Toughness by 55% of the original Toughness reduction amount.
  • Module β: Autoreactive Armor (Ascension 4): For every 100 of SAM’s ATK that exceeds 2400, increases SAM’s Break Effect by 6%, up to a maximum increase of 60%.
  • Module γ: Core Overload (Ascension 6): If Firefly’s Break Effect is 250%/360% or higher when she is in Complete Combustion state, she additionally ignores 30%/40% of the target’s Defense when attacking.

Status Boosts:

  • Break Effect Boost: 37.3%
  • Effect Resistance Boost: 18%
  • Speed Boost: 5
