Understanding Hellfire's Playstyle and Skills
Hellfire operates on a philosophy of "Retribution," functioning less like a traditional soldier and more like a walking environmental hazard that incinerates anything foolish enough to enter her personal space. To fully optimize her kit and secure the resources necessary for her ascension, many veterans choose to perform a Duet Night Abyss recharge on LootBar to quickly acquire the materials needed for her demanding build. Her combat loop is counterintuitive to standard action RPG logic; instead of avoiding damage, she thrives on it. She scales almost exclusively with Maximum HP, converting her vitality into a pulsating aura of heat that melts mob waves simply by existing.
First Skill: Raging Inferno
The cornerstone of her kit is Raging Inferno, which triggers her signature "Retribution" state. Upon activation, Hellfire emits a pulse of Pyro damage every 2 seconds to all enemies within a 10-meter radius. Crucially, this damage scales off her Max HP, reaching up to 60% at max level, meaning her damage output is intrinsically tied to her bulk. Furthermore, if she takes a hit while this state is active, she retaliates with "Puncture Retribution," a burst counter-attack, and extends the duration of her burning aura. This creates a feedback loop where face-tanking enemies actually increases your DPS uptime.
Ultimate Skill: Cage of Despair
Her Ultimate, Cage of Despair, is less about raw nuke damage and more about crowd control and aggro management. It deals Pyro damage to surrounding enemies and, more importantly, applies a Taunt for 5 seconds. By forcing enemies to attack her, she guarantees triggers for her passive counterattacks. While bosses may ignore the taunt, this skill is unparalleled for clearing dense clusters of trash mobs, acting as a magnet for incoming aggression that fuels her infernal engine.
Passive Ability: Retributive Resolve
To sustain this masochistic playstyle, Hellfire relies on Retributive Resolve. This passive ability grants her HP recovery, effectively turning her into a self-sustaining engine of war. When upgraded, specifically with the "Aetherflame" node, she becomes a premier support unit when deployed as an AI partner, granting a massive +40% ATK buff to herself and any Pyro teammates. This utility alone makes her a staple in mono-Pyro compositions.
Important Introns For Hellfire: Key Upgrades
While Hellfire is functional at the base level, her true potential is locked behind her Intron upgrades, which transform her from a sturdy tank into an automated farming machine. The next Intron level is unlocked by obtaining a duplicate for a character, meaning you’ll have to obtain 6 duplicates for Hellfire to reach Intron 6, which is tedious. Luckily, you can benefit from a Duet Night Abyss recharge to unlock Intron 6 right away.
Intron 1 (Proximity Power): Increases damage dealt to enemies within a 6-meter radius by 30%. Since Hellfire lives in melee range, this is a permanent, unconditional damage multiplier.
Intron 4 (Rapid Retribution): Reduces the internal cooldown of her counter-attack to 1.4 seconds. This significantly ramps up her burst damage frequency in heavy combat.
Intron 6 (The Automaton): The holy grail of her build. It allows Hellfire to automatically cast Cage of Despair whenever teammates use sanity-consuming skills that consume at least 5 sanity. This enables a completely AFK playstyle where Hellfire protects your team and deals damage without you ever swapping to her.
How to Set Up Demon Wedges
The Demon Wedge system is where you solidify Hellfire's identity as a health-stacking monster. Unlike other characters hunting for Crit Rate, your singular obsession here is HP%.
For set bonuses, the Phoenix series is your best-in-slot choice. Specifically, Phoenix's Blaze or Phoenix's Nirvana wedges are ideal because they synergize with the "Pyrotail" Geniemon, which boosts stats from Phoenix wedges. If you are building her purely for support, Typhon's Prime Serenity is a viable alternative, providing team-wide Sanity regeneration that helps your main DPS spam their skills, which in turn triggers Hellfire's Intron 6 auto-casts. If you are struggling to farm these specific wedges, a quick Duet Night Abyss recharge can help you secure the resources for more runs.
Prioritize stats in this order: Max HP > Skill Duration > Skill Range. Extending the duration of Raging Inferno ensures you have zero downtime on your damage aura.
Best Weapons for This Build
Weapon choice for Hellfire is surprisingly rigid because her scaling is so unique.
The undisputed champion is her signature Greatsword, Punitive Inferno. This weapon is tailor-made for her, offering a colossal +50% to +100% Max HP boost depending on its ascension. It's passive also extends Skill Duration when any Pyro character on the team takes damage, perfectly syncing with her kit's desire to tank hits.
If you lack the signature, you face a dilemma. Some players experiment with the Wanewraith Polearm for its Skill Damage bonus, but losing the massive HP pool from Punitive Inferno generally results in a net loss of survivability and damage. For budget builds, stick to any Greatsword like Ironforger that can offer defensive utility, or simply any "stat stick" weapon that happens to have high HP substats.
Team Composition For Hellfire
Hellfire shines brightest when she is enabling others or creating space for glass cannons.
The Mono-Pyro "Burning Wall": Pair her with Lynn (Main DPS) and Margie (Buffer). Hellfire provides the +40% Pyro ATK buff and keeps enemies grouped and taunted, allowing Lynn to unleash devastating AoE attacks without fear of interruption.
The AFK Farmer: Combine Hellfire (with Intron 6) with Rebecca and Truffle. Rebecca's Jellyfish turrets handle ranged enemies, while Hellfire automatically taunts and burns anything that gets close. This composition is famous for clearing daily commissions with zero input from the player.
Is Hellfire Worth Investing In?
Hellfire is a polarizing unit; she will not top the speedrun charts against single-target bosses, but she is unrivaled in comfort and farming efficiency. If you value your time and want a character who trivializes 90% of the game's mob content, she is absolutely worth the investment, and you can simply top up Duet Night Abyss on LootBar to accelerate her development if you are eager to reach her power ceiling. She is the ultimate quality-of-life character, turning tedious grinds into a walk in the park.
