Basic skills

Firefly plays from penetration effect and belongs to the class of universal damage dealers of the Path of Destruction, therefore it has high single and massive damage. The girl's specificity is to consume a significant part of her health to recharge her superpower, the cost of which is 240 units. energy. In the enhanced state of the ultimate, buffs are applied, and the skill and basic attack are changed to other skills with increased damage and the ability to cause a fiery weakness in the enemy.

A regular skill helps fill the energy of a superpower by half, while taking away health. After switching to the ultimate stance, all attacking skills gradually restore the spent HP, at the same time reduce the resistance of enemies with greater efficiency and can inflict “super penetration damage”. The fact that the heroine has two states - normal and enhanced - forces us to understand how Firefly’s abilities work, as well as to track the relationship between skills. Let's take a closer look at these points below.

Active skills

First of all, it is worth examining the main skills of the character, which include: technique, basic attack, skill и superpower.

Command: Meteorite Burn

Technique "Order: Meteor Incineration" || Weakening

Lifts into the air, where he can move without restrictions for 5 seconds. When time runs out or an attack is performed, Sam immediately descends into the target area and attacks all enemies. Upon entering battle, for 2 turns at the beginning of each wave, inflicts fire vulnerability on all enemies, then deals fire damage to all enemies equal to 200% of Sam's attack power.

Order: Flame Charge

Basic Attack "Order: Flame Charge" || Single attack

Deals fire damage to the target equal to 50-130% from the strength of Sam's attack.

Firefly Type IV: Pyrogenic Execution

Basic Attack "Firefly Type-IV: Pyrogenic Execution" || Single attack

Restores health equal to 20% of max. Sam's HP. At the same time, deals fire damage to one enemy equal to 100-260% from the strength of Sam's attack.

Order: Aerial bombardment

Emboldening Salvo "Order: Aerial Bombardment" || Single attack

Consumes health equal to 40% of max. Sam's HP to restore 50-65% superpower energy. Deals fire damage to one target equal to 100-250% from the strength of Sam's attack. If Sam's current HP is not enough, Sam's health is reduced to 1HP. Using a skill advances your next action by 25%.

Firefly Type IV: Death Star Overload

Emboldening Salvo "Firefly Type-IV: Death Star Overload" || Explosion

Restores health equal to 25% of max. Sam's HP. Before hitting, inflicts fire vulnerability on enemies for 2 turns and deals fire damage equal to (0,2 * penetration effect + 100-250%) from Sam's attack power. At the same time, deals fire damage to adjacent targets equal to (0,1 * penetration effect + 50-125%) from Sam's attack power. A maximum of 360% of the penetration effect is taken into .

Firefly Type IV: Complete Combustion

Superpower "Firefly Type-IV: Complete Combustion" || Strengthening (Energy: 240)

Upon entering the Full Combustion state, Sam's action advances by 100% and his base attack and skill are changed to the enhanced Pyrogenic Decimation and Death Star Overload. The countdown for exiting the “Full Burn” state is displayed on the action sequence and has its own fixed speed (70 units). While in a stance, you cannot use your superpower again.

Complete combustion:

• Sam's speed increases by 30-75 units;
• the penetration efficiency of an enhanced skill and basic attack increases by 50%;
• Vulnerability damage received by targets from an enhanced skill and basic attack is increased by 10-25%.

ive skills

Firefly's ive skills include a talent that is aimed at increasing her survivability.

Fire core of cocoon

Talent "Fire Core of the Cocoon" || Protection

The lower the current health value, the less damage Sam takes. When HP is below 20%, damage reduction reaches maximum value 20-50%. In the Full Burn state, the reduction in damage taken is always equal to its maximum, and resistance to effects is increased by 10-40%. If the energy is below 50% at the start of the battle, the superpower energy bar is filled to 50%. As soon as the energy reaches its maximum, all negative statuses are removed from Sam.

The order of leveling abilities

Superpower > Skill = Talent > Basic Attack

The overwhelming majority of the heroine’s damage is penetration and “super penetration” damage, for which it is important to level up ultimate. Accordingly, you can spend resources on Firefly’s other attacking skills at will. Upgrading the talent is necessary if the team does not have a healer or shield member.

Tracks

All traces of Firefly:

Penetration effect +5,3% (level 1)
"Module α: Immediate Explosion": Attacks while Fully Burned deplete the Fortitude of enemies without a Fire Vulnerability by 55% of the original Skill Fortitude damage. “Pyrogenic Decimation”: 45 durability against an enemy with fire vulnerability without taking into the increase in penetration efficiency => 25 without fire vulnerability.	Status Resistance +4% (A2)	Penetration effect +5,3% (A3)	Speed ​​+2 (A3)
"Module β: Instant Armor": When the penetration effect value is above 200%/360%, attacks in the Full Burn stance against enemies in the pierced vulnerable state will convert the amount of durability reduction into 1 hit of 35%/50% "super penetration damage".	Penetration effect +8% (A4)	Status Resistance +6% (A5)	Penetration effect +8% (A5)
"Module γ: Kernel Overload": for every 10 units. Sam's attack power exceeding 1 units, the penetration effect increases by 800%.	Speed ​​+3 (A6)	Effect resistance +8% (level 75)	Penetration effect +10,7% (level 80)

The final increase for each characteristic:

• penetration effect - 37,3%;
• resistance to effects - 18%;
• speed - 5 units.

Eidolons

Let's consider all the Firefly constants:

number	Name	<font><font>Materials</font></font>
1	I rested in a red cocoon	When using the enhanced skill Firefly Type-IV: Death Star Overload, 15% of the enemy's defense is ignored. An enhanced skill does not consume command skill points.
2	I fell from a broken sky	Using an empowered basic attack or skill while in Burn to finish off an enemy or break through their vulnerability allows Sam to perform an additional action. This effect can trigger again after 1 turn.
3	I sleep among the silent stars	Skill level +2, maximum - 15. Basic strike level +1, maximum - 10.
4	I saw a firefly fire	In the Full Burn state, resistance to effects increases by 50%.
5	I shine in a sleepless night	Superpower level +2, talent level +2. The maximum level is 15.
6	I blossom into tomorrow	In the “Complete Burn” state, penetration of fire resistance increases by 20%. Using an enhanced basic attack or skill increases penetration efficiency by 50%.

Firefly's best eidolons are E1, E2 и E6:

• First eidolon aimed at increasing damage and reducing the consumption of command skill points. Due to the constant progression of the action, increased speed and the need to use the skill, the girl wastes a significant part of the command resource in her normal state and in the ultimate stance.
• Second eidolon is the strongest, as it creates the opportunity to perform two actions in a row. Provided that the heroine is in the “Full Burning” stance and has broken through a vulnerability or completely destroyed the enemy, she can make an additional attack. Given the high efficiency of penetration and the constant imposition of weakness to one's element, in a battle scenario with a large group of enemies one can get quite a few consecutive turns.
• Sixth Eidolon in general, it increases all damage dealt by ignoring enemy fire resists. In addition, in addition to the initial 50% penetration efficiency, the heroine receives another +50%, which has a positive effect not only on reducing durability, but also on damage from the “Module β: Instant Armor” trail.

For F2P players, it is not recommended to go beyond the first two eidolons.

How to Play Firefly: Rotation

Firefly in Hankai: Star Rail focuses on damage and penetration in the enhanced state of "Full Combustion". The heroine's transition to a stance is helped by a skill that fills the energy of the super ability by 50%, while the basic attack is only needed to restore skill points.

While in "Full Burnout", gains updated abilities with high durability bar reduction and damage, significantly increases own speed and can deal "super penetration damage". In addition, the skill begins to damage the area and impose a fire type of vulnerability on enemies.

Based on the characteristics of skills in stances, Firefly’s rotation is based on the following principle:

1. If there are penetration effect buffers in the squad, use the Harmony Pathfinder and Ruan Mei techniques before launching Sam.
2. Thanks to the Pyronexus Shell talent, Sam's ultimate energy is always half full at the beginning of the battle. On your turn, use a skill to fully charge your superpower.
3. Wait until all s activate buffs and ultimates.
4. Use your ultimate and get 100% action progression. Perform a skill attack to apply a fire weakness to an area and remove most of the vulnerability bar.
5. In the next turns, when choosing between a basic attack and an E0 skill, proceed from the needs of the team so as not to go into a deficit of skill points. With E1, the enhanced skill does not consume command action points.
6. After exiting the Full Burn state, use the skill in the next two turns to repeat the rotation from step #3.

Advantages and disadvantages

Having considered the entire set of active and ive abilities, we can draw the following conclusions about the advantages and disadvantages of the character:

Advantages	Disadvantages
Despite the high cost of the superpower, it accumulates energy for the ultimate for 2 uses of the “Order: Air Bombardment” skill.	Needs proper distribution of skill points in order to activate a skill every turn and generate energy for the ultimate in the shortest possible time.
When assembling, you do not need to balance various characteristics; it is enough to bring the penetration effect, attack power and speed to high values.	Strongly reduces one's own HP with a normal skill and, without timely healing or a shield, is in a dangerous position.
A powerful set of buffs for E0, which includes increased speed, penetration efficiency and damage.	Does not benefit from alliances with strong s that increase crits and damage. Because of this feature, you will need to pump up attack power buffers, Imaginary GG or knock out ruan mei.
Inflicts a fire vulnerability in an area and converts attack power into a penetration effect, simplifying gameplay and building.	Inevitably loses damage against enemies equipped with the ability to protect the durability bar from being broken.
The best buffer is completely free "On the Fall of the Aeon".

Best Firefly Builds in Honkai: Star Rail

Firefly in HSR follows a playstyle of breaking through enemies' toughness bars and then dealing "super penetration damage." The ability to attack with this type of damage is provided in the “Complete Burning” state, which can be entered after activating the ultimate. Despite the high cost of the superpower, there is no need to collect energy recovery speed: the girl accumulates all 240 units of energy in two uses of the skill. After the transition, penetration efficiency, speed parameter and penetration damage increase.

Accordingly, in order to understand how to assemble a Firefly in the XSR, it is necessary to consider the needs of the damage dealer in both regular and reinforced stances. To go into the “Full Combustion” state, you need to wait in line and use the skill, so you will need to level up penetration effect, since “super penetration damage” depends on this parameter. The characteristic is pumped directly through relics and cones, as well as through the “Module γ: Core Overload” track, which needs Attack Power.

Since crit. chance and crit. damage does not affect the damage of penetration and “super penetration”, they are not priority parameters. These characteristics affect the direct damage of abilities and complicate the balance of stats, so it is more advisable to direct forces to build an assembly and a squad from breaking through the vulnerability. As for survivability, through traces and talent Sam receives high resistance to effects, so it is additionally recommended to collect only health and defense.

Recommended characteristic values

Main characteristics of cave relics and planar jewelry:

Relic	Main characteristic
Head	HP (permanent)
Arms	Attack Power (Permanent)
Body	ATK
Legs	Speed
planar sphere	ATK
Connecting rope	Penetration effect

Below are the characteristics to look for in relic parts:

• penetration effect;
• Attack Power;
• speed;
• HP/Def.

Optimal final values ​​of all indicators:

• penetration effect (EP): bring to 250% or, ideally, to 360% to activate the "Beta Module" trace and the "Iron Cavalry" set ive;
• Attack Power: from 2;
• speed: 143-150 units. excluding the ultimate buff;
• health: from 2 units and above.

How to collect 360% of the Firefly penetration effect

Since the penetration effect is the most important characteristic in the damage dealer build, let’s take a closer look at the ways to set a high parameter value:

• Trace studies: 37,3%.
• Iron Cavalry Cave Relics: 16%.
• Planar decorations "Lotus Lantern of the Palace": 40%.
• Connecting rope: 64,8%.
• Ruan Mei: 20% (traces).
• Pathfinder (Imaginary): 52,5% (EP 150%, E4, active ultimate level 10) or Fugue: 60% (trace "Essence of Phecda" and skill).
• “Watchmaker of Sleepy Shenanigans” on : 30%.
• Light cone, body and sphere on attack power, trace "Gamma module": "Where dreams should rest" R1 - 93,3%; “On the Fall of an Aeon” R5 – 95%.

Сonclusion: 353,9-355%.

For further pumping, you need to look for the penetration effect and attack power as a percentage in the lower parts of the relics. Additional sources include the Pioneer (Imaginary) with the ability to pump up characteristics up to 300%, as well as third-party bonuses that can be implemented through the equipment of Harmony characters.

Ultimate Light Cone [Weapon]

Firefly weapons must be Path of Destruction. Otherwise, the heroine will not be able to activate the effects of her ive ability, but will only receive increases to the basic characteristics of attack power, defense and health.

As for bonuses in the Light Cone skill, the options for increasing are suitable penetration effect or attack power. The Firefly signature is desirable in this case, as it gives a high “net” increase to the key stat and enhances the damage of the mechanics through which the girl plays. However, among the weapons you can find no less worthy alternatives:

Best relics

Like weapons, artifacts for Firefly are aimed at enhancing a key characteristic penetration effect and alternative parameter attack power. Since the penetration mechanics are enhanced by cutting and breaking through defenses, you can additionally consider specialized kits for ignoring resists.

Cave relics [main artifacts]

Planar Ornaments [Additional Artifacts]

Detachments

In HSR, Firefly plays on specific mechanics related to reducing the vulnerability scale and inflicting “super penetration damage” on enemies in a state of destroyed stamina. Because of this feature, it requires narrowly targeted s for the penetration effect in the team, but plays well with classic buffers of attack power and speed. Throughout the battle, it imposes a weakness to the fire element on enemies, which opens up the possibility of building a mono-fire group with sub-dampers and secondary damage dealers of this element. In turn, both shield warriors and healers are equally suitable for the defensive slot.

Best characters

Let's look at the heroes with whom you can form strong teams:

Top Teams

The best units for Firefly always include Ruan Mei and Pathfinder (Imaginary), but there are other viable alternatives:

Offering for consideration a detailed guide to Firefly in Honkai: Star Rail, one cannot help but dwell on F2P packs consisting of starting and epic characters. Below you can see examples of groups with 4⭐ heroes:

Is it worth knocking out?

Firefly is a representative of the Path of Destruction with a fire element. In battle, he relies on the enhanced state of Sam's combat armor, in which the vulnerability of enemies is more effectively penetrated and the opportunity to attack with “super penetration damage” appears. A key advantage that ensures comfortable gameplay in any circumstances is the ability to inflict vulnerability on enemies to an element of its type. Due to its independent gameplay, it can act as both a primary and secondary damage dealer, gathering mono-elemental groups around itself. However, it demonstrates its greatest effectiveness in specialized builds focused on penetration mechanics.

Path of Destruction DPS characters are in high demand when completing a variety of content, so knocking out Firefly is worth it for those who want to get a universal damage dealer. The heroine differs from representatives of her class in her independence in any battle scenario due to her independent vulnerability and increased resistance penetration. Despite the high compatibility with the limited legendary "On the Fall of the Aeon".

Which is better for Firefly: Signa or E1

The first eidolon seems to be a better investment than a signature weapon. In "Full Combustion" state speed the heroine effortlessly reaches 200 units. with fully upgraded boots for speed, tracks and superpowers. In this case, before the counter goes off, you can perform up to 4 actions - alternate between a basic strike and a skill, or use up most of the team skill points. With the first eidolon, the enhanced skill can be used constantly, since it does not consume action points, in addition, it ignores the enemy’s defense.

The advantage of the light cone lies in the high increases in penetration effect and increasing the damage of the corresponding mechanics. However, the Gamma Module trail offers an alternative way to gain the main stat through attack power. In such a situation, you can find a worthy replacement for signature weapons, compensating for the less beneficial ive by increasing the damage with the eidolon.

Knock out Ruan Mei or E1?

ruan mei is a valuable acquisition for the and a priority in Firefly groups, therefore it is eliminated first. Buffer gives the group important characteristics of speed and penetration effect, but, most importantly, increases the penetration efficiency by 50% and does not allow enemies to restore stamina. Scientist is friendly to skill points, so will help compensate for the lack of the first duplicate.

After getting the buffer, you can target Firefly's eidolons 1 and 2, which greatly simplify turn-based combat. Investments such as E1 Ruan Mei and Firefly's sign are equivalent for the group, so the choice can be made in favor of any of the heroines.

Achievements

There is one achievement associated with the character:

• I... will make the seas burn! - Use Firefly IV: Death Star Overload 4 times before Sam's Total Burnout status ends in a single battle. Reward: star jade ×5. To unlock the achievement, you need to use the enhanced skill 4 times while the effect of the superpower is active.
