CAMILLE WEAPON: BLESSING OF LUSTROUS CARMINE

Blessing of Lustrous Carmine is Camille’s signature six-star polearm in Arknights: Endfield, and it is built around one job: turning Camille from a Heat enabler into a team-wide buff engine. Its passive, Flow: Absolver of Guilt, fires twice over from the same actions Camille already takes in combat, granting the whole squad bonus ATK whenever he recovers SP and bonus DMG dealt whenever he applies Heat. Pair that with sub-stats that lean directly into his kit (Agility Boost and Heat DMG Boost), and you have a weapon that does very little for a random operator but a great deal for the one person it was designed around. This guide breaks down what the weapon actually does, why it is so tightly coupled to Camille, how it compares against every other polearm he can realistically equip, and whether it is worth the Arsenal currency to chase.

TL;DR - Key Points

• Type: Six-star polearm, Camille’s signature weapon. Sub-stats are Agility Boost [L] and Heat DMG Boost [L].
• Passive, Flow: Absolver of Guilt: raises Ultimate Gain Efficiency, grants the whole team increased ATK when the wielder’s skill recovers SP, and grants the whole team increased DMG dealt when the wielder’s skill applies Heat.
• Why it matters: Camille both recovers SP and applies Heat through his normal rotation, so he triggers both halves of the passive without playing around it.
• Best alternative: Beacon of Duty, the other Heat-flavored six-star polearm, which buffs the team’s Physical and Heat DMG dealt and is easier to obtain (Protocol Pass).
• Budget alternative: Chimeric Justice (5-star), for the Ultimate Gain Efficiency sub-stat and an ATK spike on Vulnerability.
• Best on Camille, mediocre elsewhere: the Heat trigger is dead weight on an operator who cannot apply Heat, so this is a signature weapon, not a generalist pick.
• Where to get it: the Arsenal Exchange in the Acquisition Center, and the Crimson Hued Issue weapon banner.

What Blessing of Lustrous Carmine Does

The weapon’s identity lives entirely in its passive, Flow: Absolver of Guilt, which bundles three effects:

• Ultimate Gain Efficiency increased. The wielder builds toward their ultimate faster, which feeds back into the rest of the kit by getting Camille’s big buttons online sooner.
• SP recovery, team ATK buff. When the wielder’s skill recovers SP, the entire team gains increased ATK for a duration.
• Heat application, team DMG buff. When the wielder’s skill applies a Heat effect, the entire team gains increased DMG dealt for a duration.

That two-buff design is the important part. Most polearms reward a single behavior. Blessing of Lustrous Carmine asks for two things at once, ATK on SP recovery and DMG dealt on Heat, which is exactly why it is a signature rather than a shared weapon. On the right user it is two buffs in one slot. On the wrong user it is one buff and a wasted line of passive.

The two triggers

The first trigger keys off SP recovery, the most universal mechanic a Vanguard touches. Every time Camille’s skills restore SP, the team ATK buff refreshes. Because feeding SP to the team is the core of his job, this side of the passive is effectively always live in a real fight.

The second trigger keys off Heat application. When Camille’s skill applies a Heat effect, the team gains increased DMG dealt. This is the half that makes the weapon a signature: it only pays out if the wielder is dealing Heat, which on Camille is constant and on most other operators is zero. The DMG-dealt buff is also broader than an ATK buff in a Heat-focused team, since it amplifies the final damage number rather than just the attack stat that feeds into it.

The sub-stats

The two sub-stats reinforce the same theme:

• Agility Boost [L] improves the wielder’s action economy, which loops back into the SP-recovery trigger by letting Camille act more often. Agility also appears to be the main attribute that Heat Vanguard polearms scale around, so it is a clean stat rather than a filler line.
• Heat DMG Boost [L] is pure signature glue. It only matters if the wielder deals Heat damage, which on this weapon is the entire point.

Neither sub-stat is wasted on Camille, and both are largely wasted on a Physical, Electric, or Arts operator. That is the cleanest signal that this weapon was purpose-built.

A note on the numbers

The Weapon Info screen describes both buffs qualitatively (“increased ATK”, “increased DMG dealt”) and does not list exact percentages, so we are deliberately not quoting hard values here. Treat any figure floating around in early 1.3 discussion as a community estimate pending confirmation, not a confirmed datasheet. What is confirmed is the shape of the weapon: two independent team-wide buffs gated behind two different actions, both of which Camille performs natively. When the localized values are confirmed we will update this guide.

Why It Fits Camille

Camille is a Heat Vanguard whose role in a team is to keep SP flowing and to stack Heat pressure for the carries behind him. If you have read our full Camille build guide or the Mi Fu and Camille build guide, you already know the loop: he batteries the team, he applies Heat, the carries convert that into damage.

Blessing of Lustrous Carmine pays him for doing both of those things. Every time his skill recovers SP, the team ATK buff refreshes. Every time his skill applies Heat, the team DMG-dealt buff refreshes. Because these are the two pillars of his normal rotation, he keeps both buffs active without changing how you play him. He is, in effect, double-dipping the passive, and the two buffs hit different parts of the damage formula (attack stat and final damage dealt), so they multiply rather than overlap.

Contrast that with a generic SP battery like Akekuri or Pogranichnik, whose SP profiles we compare in the Akekuri vs Pogranichnik breakdown. Those operators recover SP all day, so they would trigger the ATK half of this passive just fine, but they cannot apply Heat, so the DMG-dealt half never fires. They would be paying a signature-weapon price for half a weapon. That is the whole argument for keeping this polearm on Camille and giving the universal options to your universal batteries.

There is also the Ultimate Gain Efficiency line. Camille’s value spikes when his stronger skills are available, so anything that shortens the wait between rotations compounds across a fight. On him, the efficiency boost is not a throwaway stat, it is a tempo upgrade that loops back into both triggers: faster skills mean more SP-recovery events and more Heat applications, which means higher buff uptime.

Keeping both buffs live

The practical goal in combat is uptime on both halves of Flow: Absolver of Guilt. In Camille’s standard rotation that means leading with the skills that restore SP to refresh the team ATK buff, then chaining into the Heat application that refreshes the team DMG-dealt buff. Because both buffs run on their own duration timers, you are not choosing between them, you are layering them. As long as Camille is doing his normal job, a competent rotation keeps the squad sitting on both buffs for the majority of a fight. The weapon does not ask you to play around it, which is exactly what you want from a support piece: the optimization is invisible.

The Polearm Pool: Camille’s Real Alternatives

Here is a correction worth stating plainly, because it trips up players coming from other classes. Camille is a polearm user. The famous universal Vanguard weapon, the Thermite Cutter, is a sword, so Camille cannot equip it. Weapons in Arknights: Endfield are restricted by type, which means every alternative you might give Camille has to come from the polearm pool. That pool is smaller and more specialized than the sword pool, so the choice is genuinely narrow.

These are the polearms most relevant to a Heat Vanguard, ranked by how well they serve Camille specifically.

Beacon of Duty: the closest substitute

If you do not pull the signature, Beacon of Duty is the polearm to reach for. It is the other Heat-themed six-star, and it is thematically the closest thing to Camille’s signature. Its sub-stats are Agility (the same main-attribute scaling) and Ultimate Gain Efficiency, and its passive, “Efficacy: Fuel for the Torch,” grants a flat Heat DMG Dealt boost, a personal Physical and Heat DMG buff when the wielder applies Heat Infliction, and a team-wide Physical and Heat DMG Dealt buff when the wielder applies Heat Susceptibility.

That team buff is the key line. Where the signature buffs raw ATK and general DMG dealt, Beacon of Duty buffs the team’s Heat and Physical DMG specifically, which in a dedicated Heat squad lands on almost everything that matters. It also keeps the Ultimate Gain Efficiency that Camille loves. The two reasons the signature still wins are that Beacon of Duty’s team buff is gated behind Heat Susceptibility (a narrower condition than simply recovering SP), and that it does not carry the ATK-on-SP-recovery half at all. You are trading the universal ATK buff for an element-specific DMG buff. In a pure Heat team that trade is small, which is why Beacon of Duty is a genuinely strong consolation prize rather than a step down. It is also typically obtained through the Protocol Pass, making it the most accessible high-end polearm on this list.

Chimeric Justice: the budget battery

For players who have not landed a six-star polearm, Chimeric Justice is the sensible five-star. It carries Ultimate Gain Efficiency as a sub-stat, which suits a battery operator, and its passive provides a flat Critical Rate boost plus a sizeable ATK buff the first time the wielder applies Vulnerability. It gives Camille no Heat scaling and no team buff, so it is purely a personal stat-stick, and its Strength sub-stat does not line up with his Agility scaling as cleanly as the dedicated polearms do. But it keeps him cycling skills quickly and costs a fraction of a six-star. As a bridge weapon while you save Arsenal currency, it does the job.

Valiant and the off-element six-stars

Valiant is interesting because its passive is “Combative: ATK +28%,” a large unconditional attack boost, plus a bonus Physical hit after applying Physical Statuses. The flat ATK is universal and benefits any operator, so Valiant is not a bad weapon on Camille. The problem is everything else: its second sub-stat is Physical DMG Dealt, and its bonus hit is Physical, both of which are dead weight on a Heat operator. You would be equipping a six-star and using maybe two-thirds of it. If Valiant is the only six-star polearm you own and you are not yet committed to Camille, it works, but it is strictly a placeholder.

The remaining six-star polearms are clearer skips on Camille. Mountain Bearer is Lifeng’s signature and is built around Physical damage and Vulnerability. JET is Avywenna’s signature and scales Arts damage. Among the five-stars, OBJ Razorhorn wants Cryo and Solidification, and Cohesive Traction wants Electric. None of these align with Heat, so while Camille can technically hold them, their passives sit idle. The honest polearm shortlist for Camille is short: his signature, then Beacon of Duty, then Chimeric Justice as a budget bridge.

Should You Pull or Build It?

Here is the honest framing.

Pull it if: Camille is a core member of your main team and you intend to invest in him long term. The double buff is genuine, it scales the damage of everyone standing behind him, and the sub-stats are tailor-made for his kit. On a dedicated Camille build this is best-in-slot, and nothing else in the polearm pool replicates the SP-recovery ATK buff.

Skip it if: you pulled Camille as a flex piece, you are short on Arsenal currency, or you do not yet have the Heat carries that turn his DMG-dealt buff into real numbers. Beacon of Duty covers most of the gap for a fraction of the chase, especially if you are already buying the Protocol Pass. The signature is an upgrade, not an unlock.

For free-to-play players, the priority order is usually operators first, then a single flexible weapon, then signatures. Blessing of Lustrous Carmine is a luxury upgrade. Camille performs his job with Beacon of Duty or even a five-star placeholder, and the signature sharpens an already-functional kit rather than enabling it. If your account is young, spend on breadth before you spend on this.

How to Get It

Blessing of Lustrous Carmine is available from two sources:

• Acquisition Center, Arsenal Exchange. The weapon appears in the exchange shop, which lets you target it directly with Arsenal currency rather than relying on banner luck. This is the deterministic path: save up, buy it, done. For a single copy to unlock the passive, this is the route most players should plan around.
• Crimson Hued Issue. This is the weapon banner where the polearm can drop. Pulling here is the gacha route, with the usual variance, and it is where duplicates for higher Potential generally come from.

Arsenal currency in Arknights: Endfield is earned largely through pulling on character banners, so weapon acquisition is tied to your overall summoning activity. The practical takeaway is to decide in advance whether you want one copy (buy it from the exchange when you can afford it) or a maxed-Potential version (commit to the Crimson Hued Issue banner and accept the variance). One copy gives you the full passive. Additional copies raise the weapon’s Potential, which pushes the buff values higher, but that is optimization rather than a requirement, and it is rarely worth chasing on a support weapon when that currency could secure another operator instead. As with any weapon banner, spend against a budget you set beforehand rather than chasing on tilt.

FAQ

Is Blessing of Lustrous Carmine worth it? On a Camille main, yes. It is his best-in-slot weapon because it converts his two normal actions, SP recovery and Heat application, into two separate team-wide buffs. If you are not building Camille seriously, it is comfortably skippable in favor of breadth elsewhere.

What is the best alternative if I skip the signature? Beacon of Duty, the other Heat-flavored six-star polearm. It buffs the team’s Physical and Heat DMG dealt when the wielder applies Heat Susceptibility, carries the Ultimate Gain Efficiency that Camille wants, and is usually obtainable through the Protocol Pass, which makes it far more accessible than a banner signature.

Can I just use the Thermite Cutter? No. The Thermite Cutter is a sword, and Camille is a polearm user, so he cannot equip it. Every alternative for Camille has to come from the polearm pool, which is why the realistic shortlist is the signature, Beacon of Duty, and Chimeric Justice.

What is the best budget polearm for Camille? Chimeric Justice, a five-star with an Ultimate Gain Efficiency sub-stat and an ATK spike on Vulnerability. It gives no Heat scaling and no team buff, but it keeps him cycling skills quickly and is a fine bridge until you secure a six-star.

Does Blessing of Lustrous Carmine work well on operators other than Camille? Not really. The ATK-on-SP-recovery half works on any SP battery, but the DMG-dealt half only fires when the wielder applies Heat, and the Heat DMG sub-stat is dead weight on a non-Heat user. You would be paying a signature price for half the weapon.

Do I need duplicates? No. One copy gives you the full passive. Duplicates from the Crimson Hued Issue banner raise its Potential and push the buff values higher, but that is optimization, not a requirement, and is low priority on a support weapon.

Where exactly do I buy it? The Arsenal Exchange in the Acquisition Center for the targeted purchase, or the Crimson Hued Issue weapon banner for pulls and duplicates.

Verdict

Blessing of Lustrous Carmine is a textbook signature weapon. It is not the strongest polearm for a random operator, and it is not the smartest single-weapon investment for a thin account. What it is, is the best possible polearm for Camille specifically, because it pays him twice for the rotation he already runs: ATK for the team when he recovers SP, and DMG dealt for the team when he applies Heat. No other polearm carries the SP-recovery ATK buff, which is why it sits at the top of his list.

If Camille anchors your roster, the signature is the upgrade that makes his support ceiling match his theme. If he does not, Beacon of Duty covers most of the same ground at a lower cost, and a five-star like Chimeric Justice keeps him running while you decide.
