Team Guide for Firefly in HSR

In a team, Firefly plays the role of a damage dealer and plays from a specific mechanic tied to reducing the vulnerability scale and inflicting "super-break damage" on enemies in a state of destroyed toughness. As a result, due to the named feature, she requires narrowly focused supports in the team.

Which characters are suitable?

The following units will offer Sam a high level of synergy:

Character	Features
The Dahlia (Nihility: Fire)	Constance compensates for the main shortcomings of the Stellaron Hunter: Allows you to trigger super break even when the stamina bar is full; saves skill points; Gives a high speed boost, additional stamina damage and energy. At the same time, it offers standard buffs in the form of effect and break efficiency, cuts defense and applies vulnerabilities.
MC (Harmony: Imaginary)	Is the best free partner for Sam, playing in similar mechanics. Not only helps to gain additional BE, but also gives the opportunity to deliver several blows with "super-break damage", which is what the girl in mech armor specializes in.
Ruan Mei (Harmony: Ice)	A universal support that increases the effectiveness of break of any groups. This ability has a positive effect on "super break damage", the work of which is provided through the trace "Module β: Autoreactive Armor". In addition, the scientist increases the team's speed and break effect, and also does not allow enemies to restore the stamina bar for a long time.
Fugue (Nihility: Fire)	Replaces Ruan Mei the Scholar or Harmonious Pathfinder, and can also be placed in the third position of a team alongside the aforementioned heroes. Increases EVP, decreases enemy target defense, and supports the team with additional damage.
Lingsha (Abundance: Fire)	A support character with a variety of functions: healing, area-of-effect attacks, and a debuff that increases the damage of fully depleted stamina.

• Credits ×3 888 000;
• Traveler's Guide × 290;
• Tracks of Destiny × 8;

How the skills work

The heroine relies on penetration and belongs to the Destruction class of damage dealers, delivering high single and area-of-effect damage. Her specialty is consuming health to recharge her ultimate, which costs 240 energy. While in her ultimate state, she receives buffs, and her skill and basic attack receive increased multipliers and the ability to inflict Fire Weakness.

Active skills

Basic skills (except for techniques and ultimates) are divided into two types: standard and enhanced. A basic skill fills the ultimate ability halfway, but in exchange, it drains health. After entering the ultimate stance, skills gradually restore the HP spent, simultaneously reducing enemy durability and potentially inflicting "super-piercing" damage.

Passive abilities

Passive skills include the talent, aimed at increasing the survivability of the Huntress.

Skill leveling order

Ultimate > Skill = Talent > Basic attack

The overwhelming majority of damage comes from penetration and “super-penetration”, for which it is important to upgrade ultimateAccordingly, it's recommended to spend resources on other skills after upgrading the superpower. Improving the talent is necessary if the team lacks a healer or shielder.

Traces

Character talent tree:

• Ascension Level 2 - Module α: Antilag OutburstWhile in the "Full Burnout" state, your E/P is increased by 25%. When using a boosted basic attack or skill that penetrates a target's vulnerability, the "Full Burnout" counter is delayed by 10%. This bonus can be triggered a maximum of 3 times per state.
• Ascension Level 4 - "Module β: Autoreactive Armor"When the E/P value is above 150/300%, attacks in the "Total Combustion" stance against enemies in a state of pierced vulnerability will convert the durability damage of this attack into 100/150% "super penetration damage".
• Ascension Level 6 - "Module γ: Core Overload"For every 10 attack power exceeding 1800, E/P increases by 0.8%.

The total increase to each characteristic after learning "Traces":

Eidolons

Firefly's best eidolons are E1, E2 and E6.

• 1 — aimed at increasing damage and reducing skill point consumption. Due to the constant progression of the action, increased speed, and the need to use the skill, the girl expends a lot of team resources.
• 2 — is the strongest, as it allows for two consecutive actions. Provided the heroine is in the "Full Burn" stance and has penetrated a vulnerability or destroyed a target, an additional attack can be performed. In scenarios with a large group of enemies, multiple consecutive moves can be achieved.
• 6 — Increases overall damage dealt by ignoring enemy fire resistances. In addition to the initial 50% penetration efficiency, the heroine gains an additional 50%, which positively impacts not only stamina reduction but also the damage from the "Module β: Instant Armor" trail.

For F2P players, it is recommended to stop at the second const.

How to Play Firefly in HSR

The Stellaron Hunter focuses on breaking the toughness bar of enemy targets in the enhanced state of "Complete Combustion". The heroine can switch to the stance with the help of a skill that fills the energy of the super ability by 50%. While in "Complete Combustion", the girl receives updated abilities with a high decrease in the "shield" bar, significantly increases her own speed and can inflict "super-break damage".

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

1. If there are buffers in the squad, use their techniques before launching Sam.
2. Thanks to the talent "Chrysalid Pyronexus", at the beginning of the battle the energy of the character's ultimate is always half full. On your turn, use the skill to fully charge the superpower.
3. Wait until all supports activate buffs and ultimates.
4. Use the super ability to gain 100% action advancement. Perform a skill attack to apply a fire weakness in AoE and remove most of the vulnerability bar.
5. In the following turns, when choosing between a basic attack and a skill at E0, proceed from the needs of the team, so as not to end up in a deficit of skill points. With E1, the enhanced skill does not spend team action points.
6. After exiting the Complete Combustion state, use the skill on the next two turns to repeat the rotation.

Is the character worth getting?

Firefly is a representative of the Path of Destruction, a Fire elementalist in HSR. In combat, she relies on the enhanced state of her "SEM" combat armor, which more effectively penetrates enemy vulnerabilities and opens up the possibility of a "super-piercing" attack. A key advantage, ensuring comfortable gameplay in any circumstances, is the mechanic of applying a vulnerability to an element of her type.

This heroine is worth picking for those who want a versatile damage dealer and are willing to build a team around her. She's competitive in the endgame and handles most high-difficulty bosses well, but you need to invest in a build and specific supports to achieve maximum effectiveness. First and foremost, you need to get demoness Constance, without which the Huntress becomes less flexible.

Which is better: signature or E1

The first Eidolon is more beneficial than a signature weapon. With Consta, the enhanced skill can be used constantly, as it doesn't consume action points and ignores enemy defense. Additionally, this allows you to get closer to the powerful E2.

The main advantage of the Cone is its high E/P bonus. However, "Module γ: Core Overload" offers an alternative way to increase this stat through ATK. In this situation, it's best to find a replacement, compensating for the less beneficial passive through Trace and Eidolon.

Knock out Dahlia or E1

The Destruction Crew member is a valuable support and is picked first because:

• offers significant increases in speed and e/p;
• Allows you to cause super penetration when your durability bar is full.

At the same time, the demoness lowers defense and is friendly towards skill points, which partially compensates for the lack of E1.

Final investment priority:

Constantia > E1 > E2
