Firefly – Honkai Star Rail Character Guide

Firefly is a warrior who pilots the Firefly-IV type heavy armor of the Glatiramer Iron Cavalry Sky Front. She was artificially created through cloning to create a powerful army. She is currently a member of the Stellaron Hunters, better known as Sam.

About the character

The character’s story begins in the now defunct Republic of Glatiramer, destroyed by the Swarm during an invasion. They were faced with an endless supply of Spread bugs, forcing them to create “living weapons”. 

It was believed that they could change the course of the war and resist the enemy’s onslaught. Thus, the “Iron Cavalry” armor appeared, like Ironman, which is controlled by artificially created clones.

What exactly happened to our heroine after the fall of her empire is unknown to us, as is when and why she joined the criminal organization “Stellaron Hunters”. But we only know that she was one of the first and, together with Kafka, found Blade and the Silver Wolf. 

How to get

Firefly can be dropped in the Event Jump: Character “Shimmering Cocoon” from June 19 to July 10, 2024.

Pros and cons

Pros Cons
  • Quickly builds up the ultimate, in just 2 uses of the skill, although it has a high energy value for activation. 
  • Buffs itself with a huge number of stats, Speed, Penetration Effect and Damage. 
  • Automatically applies Fire Vulnerability to multiple enemies. 
  • Converts Attack Power into Penetration, making the build very simple. 
  • Fully reveals itself with a free support, namely the Pathfinder, following the path of Harmony.
  • Requires proper distribution of action points to generate energy and ult more often. 
  • Will not play with supports that buff critical damage or chance, which will force you to pump attack power buffers. 
  • Loses damage when fighting against enemies that can protect their Penetration Dur

Traces and abilities

The game style is based on breaking through enemy defense and inflicting “super-penetration damage”. To do this, you need to enter the “Full Burnout” state after using the ult. It is worth remembering that the character has the highest energy consumption rate for the super ability, namely 240 units. After switching to the form of Sam, he receives a huge number of enhancements: Penetration effect, Speed, Damage. 

For the build, you need to consider the stance in the form of Firefly and Sam together. It is important to focus on Speed, since you need to walk more often and use the skill to maintain shape in iron armor.

A mandatory attribute is Penetration, which determines the “super-penetration damage”. To do this, download the artifacts and look for this indicator everywhere, as well as the trace of “Module γ: Core Overload”, which converts Attack Power into Penetration Effect. 

Capabilities

Name Type Description
Order: Rocket Launcher Basic attack Punches, dealing Fire damage based on its Attack Power.
Firefly type IV: Pyrogenic decimation Basic attack Performs a series of blade attacks, restoring 20% ​​of HP and dealing pyro damage to a solo target.
Order: Aerial bombardment Skill Kicks the enemy, taking away 40% of his HP, while restoring 50-65% of the ultimate’s energy.
Firefly Type IV: Death Star Overload Skill A flurry of slashes hits multiple enemies, inflicting Fire Vulnerability for 2 turns. Sam recovers 25% of his HP.
Firefly Type IV: Complete Combustion Superpower Activates the “Full Burnout” combat mode and advances itself to 100%. Basic attack and Skill are replaced by enhanced ones, in this stance it is impossible to ult again, even if there is enough energy.
Pyronexus shell Talent The less HP you have, the less damage you receive. The maximum value of damage received varies from 20 to 50%. After using the superpower, the damage reduction is always maximum, plus resistance to effects is added in the amount of 10 to 40%. As soon as the ult scale is completely filled with energy, our mecha completely throws off all negative statuses.
Command: Meteorite Burn Technician Takes off over the visible area and dives to the point you select, the capture area is almost the entire screen. Immediately imposes pyro vulnerability on all enemies and deals damage from Attack Power.

Traces

Name When does it open? Description
Module α: Antilag Flash 2 rise Attacks in Full Combustion mode reduce the durability of enemies without Pyro Vulnerability by 55%.
Module β: Auto-reactive armor 4th rise When the Penetration Effect is above 200%/360%, all attacks in stance are converted into a reduction in durability, thus creating 35%/50% “super penetration damage”.
Module γ: Core Overload 6th rise Every 10 points of Attack Power above 1800 increases Penetration Effect by 0.8%.

Light cone

The weapon must be of the Path of Destruction, otherwise the heroine will not receive the necessary buffs and will not be able to reveal herself to the fullest extent.

Icon Name Characteristics Description
Where dreams should rest Increases the penetration effect by 60-100%. Applies the “Defeated” status to enemies, causing them to deal 24-40% more damage while reducing their Speed ​​by 20%. A signature that makes our girl an annihilating Mecha. It has significant bonuses to the main character attribute and imposes a negative status on enemies. During the fight, it activates the second cone buff, increasing Penetration and Super Penetration.
On the Fall of Aeon When dealing damage with any skill, increases attack by 8-16% and stacks up to 4 times. When the durability bar is broken, damage will increase by another 12-24%. The best option if you are unlucky with the weapon banner. You can get it almost for free by buying it in the “Gerta Shop”. It has a high base and when used correctly activates a similar buff to the signal.
A promise kept in the heart Increases Penetration Effect by 28-56%. Increases critical hit chance by 15-30% after using the Ultimate. The best option among four-star cones due to the high increase in Penetration. Additionally increases the critical chance of hitting, but we do not need it, just a nice bonus.
The moles greet you Using any skill grants a stack of Mischief, each increasing attack power by 12-24%. Another good epic option, but requires max stacks.
Woof! Time for a walk! Attack power is increased by 10-20% and damage to enemies with the Burning and Bleeding debuffs is increased by 16-32%. Literally a free option, can be used if you don’t have any of the above.

Relics

Artifacts for Firefly are aimed at strengthening the key characteristic of the penetration effect and the alternative parameter of attack power. Since the mechanics of penetration are strengthened by cutting and penetration of protection, specialized sets for ignoring resistances can be additionally considered. 

Basically, it’s worth choosing Speed ​​in “legs” and sub stats, Attack Power in chest and sphere, and “rope” should be taken for Penetration Effect. This way you can see big damage numbers on your screen.

Cave relics

Iron Cavalry – a specially released set for this character, combines absolutely everything. Half will give 16% penetration, and the whole set allows you to ignore the enemy’s defense by 10% when dealing damage if the main attribute is equal to or higher than 150%. But if you put everything together correctly and the penetration effect exceeds 250%, the damage ignores 15%. 

Iron Cavalry / Clockmaker of Sleepy Machinations – A temporary solution while you farm the first set. These sets combine well with each other due to the penetration bonus. In total, you can get 32%, since each 2 parts give 16%.  

Iron Cavalry / Meteor Thief – Another variant of Firefly’s temporary outfit. In addition to increasing the most important attribute by 32% in total, energy is restored upon penetration.

Iron Cavalry / Herald Wandering in Hacker Space – a working option if you can’t find “legs” for Speed ​​for a long time and it is critically lacking. The first two parts will give 16% penetration, the second two will increase speed by 6%.

Planar decorations

Lotus Lamp Forge – new planar decorations added specifically for this hero. Increases speed by 6% and when dealing damage to enemies with fire vulnerability (and we can create it ourselves), penetration increases by 40% for 1 turn. 

Thalia – the edge of bandits – a good option if you are lucky with the drop of sub stats. The planars themselves in total give 36% penetration, but on condition that the Speed ​​is higher than 145 units, and at full pumping it will definitely be more. 

The Space Sealing Station is useful at the start of leveling up, as it increases Attack Power by 12% by default. Additionally, by another 12% with the required Speed ​​indicator, namely 120. 

Glathiramer Skyfront looks good on the character because of the automatic Speed ​​boost. When worn normally, it gives 12% attack, but if your speed is equal to or higher than 135/160 units, it will increase by another 12%/18% respectively. 

Partners for Firefly

Our heroine is played with the help of new mechanics – reducing the enemy’s vulnerability bar and inflicting “super-penetration damage”. This makes our squads more specific, since we completely abandon the Path of Harmony supports, due to the uselessness of crit acceleration. Here you can assemble a pack with a shielder or a healer, and the supports should increase the percentage of the Penetration Effect.

Eidolons

Level Name Description
1 In the reddened shell I rested The enhanced skill “Firefly Type-IV: Death Star Overload” ignores 15% of the enemy’s defense. This skill does not consume action points.
2 From the broken sky I fell freely The Power Attack and Combat Stance skill allow Sam to perform an additional action for another attack.
3 Among the silent stars I sleep deeply +2 to skill, +1 to base attack.
4 I will soon look at the glowing firefly When using the ult, resistance to effects increases by 50%.
5 From a long sleepless night I will shine +2 to ult and talent.
6 In the completed sadness I blossom Penetration is increased by 20% while in the Full Burn state. Using a Powered Attack or Skill will increase this by an additional 50%.

Firefly is one of the few pyro damage dealers in the game at the moment. In conjunction with the unique and meta mechanics of Penetration, it is definitely worth paying attention to it. Easy to assemble and not demanding on signature weapons.
