The Queenbreaker — Wire Discipline (Hunter)

Unstoppable-champion + miniboss deleter from range

Weapon: The Queenbreaker (Linear Fusion Rifle · Heavy · Arc) · Subclass: Arcstrider · Role: Unstoppable-champion + miniboss deleter from range Sandbox: 9.7.0 · Created 2026-06-16

A Heavy LFR that stuns Unstoppables by itself — no anti-champion artifact slot spent. Mask of Bakris's Shift dodge stacks a flat Arc-weapon damage bonus straight onto the Queenbreaker, and kills with that bonus refund the dodge that granted it. Stay amplified and every charged shot that drops a major detonates a blinding burst (Spark of Beacons). Hold the angle, Shift, fire, repeat: a one-shot champion answer that keeps its own engine fed.

The weapon

Wire Rifle (verbatim): "[Alternate Weapon Action] to swap between scopes and alter this weapon's firing behavior. Strong against [Stagger] Unstoppable Champions."

Catalyst — Rewind Rounds (verbatim): "When this weapon's magazine is empty, it refills from reserves based on the number of hits."

What it does: the Queenbreaker is the only LFR with an intrinsic Unstoppable stun baked into the gun — landing a charged shot staggers Unstoppable Champions with zero artifact mod spent. The AWA toggle trades a fast/low-zoom scope (Marksman) for a slow/long-zoom scope that hits harder and stuns from further out. Rewind Rounds turns hit-accuracy into ammo economy: empty the 5-round mag on-target and it tops itself back up from reserves, so the gun rarely makes you reload between champions. Arc element means every kill feeds the Arc subclass loop below.

Loadout

Slot	Pick	Why
Subclass	Arcstrider (Arc 3.0)	Amplified is the gate for Spark of Beacons blinds + Mask of Bakris is Arc/Stasis-only.
Super	Gathering Storm	Heavy-hitting ranged Super; the embedded staff jolts a whole pack and primes Bolt Charge fragments.
Class ability	Gambler's Dodge (becomes Bakris Shift)	The Shift grants the stacking Arc-weapon damage bonus — the whole build's damage multiplier.
Melee	Combination Blow	Melee kills stack damage + restore health/dodge; a low-cost way to refund the Shift when you're not killing with the gun.
Grenade	Pulse Grenade	Cheap, lingering Arc DoT for adds while you hold your angle; jolts with Spark of Shock.
Aspect 1	Flow State	"Defeating a jolted target makes you amplified… reload speed is greatly increased." Amplified uptime = Beacons uptime; the reload buff hides Queenbreaker's slow handling.
Aspect 2	Lethal Current	"After dodging, your next melee… jolts the target… Damaging any jolted target with melee attacks also blinds them." Every Shift hands you a jolt-on-demand to re-trigger Flow State amplified.

Fragments

Spark of Beacons amplified + Arc Heavy final blow → blinding explosion — this is the Queenbreaker as a crowd-control bomb
Spark of Ions jolted/Bolt-Charge kill → Ionic Trace = ability energy
Spark of Discharge Arc weapon kills → Ionic Trace
Spark of Shock Arc grenades jolt → free Flow State trigger

Exotic armour: Mask of Bakris (Helmet).

Other two weapon slots:

Kinetic/Primary: any Arc Primary you like the feel of (e.g. an Arc auto/SMG) so add-clear also feeds Ionic Traces and Spark of Discharge — keeps the Arc economy single-element.
Special: free slot — a Strand/Stasis Special or another Arc Special. Queenbreaker is the Heavy, so use Special for the encounter (an anti-Barrier or anti-Overload frame to cover the champion type Queenbreaker can't, per below).

Why this works (the mechanics)

Queenbreaker is its own anti-champion mod. Wire Rifle stuns Unstoppable intrinsically — under Anti-Champion 2.0 that stun rides the gun, not an artifact slot. So the build spends its artifact/Special slot on Barrier or Overload coverage instead and walks into any GM with all three champion types answered.
Mask of Bakris is the damage multiplier, and it's self-refunding. Light Shift gives "Stasis and Arc weapons a stacking damage bonus," and "final blows with this bonus active refund class ability energy." Queenbreaker is Arc → every Shift buffs the next charged shots → a buffed kill refunds the Shift. Hold angle → Shift → delete the major/champion → Shift is already back. The loop is the rotation.
Amplified is the second engine, and Flow State keeps it lit. Spark of Beacons only fires while amplified, so amplified uptime = how often your Queenbreaker kills detonate a team-saving blind. Flow State makes you amplified on any jolted kill; Lethal Current's dodge-melee jolts on demand; Spark of Shock jolts via grenade. Three independent jolt sources mean amplified almost never drops.
Beacons turns a single-target sniper into AoE control. A slow LFR normally can't crowd-control. But while amplified, an Arc Heavy final blow creates a blinding explosion — so one charged Queenbreaker shot into a major standing in a pack blinds the whole pack (suppresses their fire, buys revive/DPS space). The gun does single-target and zone denial off the same trigger.
The Arc economy reloads the gun and your abilities for free. Spark of Discharge (Arc weapon kills) + Spark of Ions (jolted/Bolt-Charge kills) spray Ionic Traces; each Trace pumps ability energy. Rewind Rounds tops the mag from reserves on accurate hits. So accuracy → ammo, and kills → abilities, with no manual reload tax on a slow weapon.
Gathering Storm is the "oh no" button that primes the loop. The thrown staff jolts a whole group → those jolted kills hand you amplified (Flow State) + Ionic Traces (Ions) the moment the Super ends, so you come out of Super already amplified and topped up for the Queenbreaker rotation.

Stats & mods

Weapons 200 → Class 100+ → Super. Weapons 200 for raw Queenbreaker PvE damage (and reserves); Class 100+ to keep Shift on a short leash since the Shift is the damage buff and the build's mobility; Super to recycle Gathering Storm.

Archetypes/tuning: prioritise pieces favouring Weapons + Class. Mods:

Helmet: Heavy Ammo Finder · Harmonic Siphon (Arc kills → Orbs).
Gauntlets: Heavy Hand / Melee mods are optional; run Loader mods are wasted on Rewind Rounds — instead take Harmonic Loader if you want faster catalyst top-ups.
Chest: Arc Resistance + one off-element Resistance for GM survivability.
Boots: Arc Weapon Surge ×2 (≈+17% Arc weapon damage — straight onto Queenbreaker) · Innervation/Insulation for ability regen off Orbs.
Class item: Bomber + Outreach (cut Shift cooldown — more Bakris uptime) · Powerful Attraction (dodge vacuums the Orbs your Arc kills make).

Artifact (anti-champion + Arc): Counter Energy (every champion stun → energy to least-charged ability — Queenbreaker stuns Unstoppables constantly, so this is near-permanent ability refund), Amped Up (stay amplified longer → longer Beacons windows), and an Anti-Barrier / Overload weapon mod matching your Special so the loadout covers the two champion types Queenbreaker doesn't.

Where it shines

Grandmaster Nightfalls / Master raids & dungeons: the headline. Unstoppables die to a single charged shot with zero artifact spend; Counter Energy refunds abilities off every stun; Beacons blinds the pack around each kill. Bakris's flat Arc bonus + Arc Surge ×2 push Queenbreaker into miniboss/Unstoppable one-shot territory.
Champion coverage: Unstoppable — handled intrinsically by Queenbreaker (Wire Rifle). Barrier and Overload are not on the gun — cover them with the artifact mod + your Special-slot frame (e.g. Anti-Barrier Sniper, Overload SMG). State this plainly: the Queenbreaker is a one-champion-type weapon that frees the rest of your kit to cover the other two.
Boss / DPS phases: a credible Heavy LFR damage option with Bakris's Arc bonus stacked + Surge mods; Rewind Rounds extends the DPS window by refilling the mag mid-burn.
Add-dense rooms: weaker — it's a precision Heavy, not a primary. Lean on the Arc Primary + Pulse Grenade + Beacons blinds for control while you pick priority targets.

Verify notes

Element/ammo confirmed from manifest (`inspect_item.py 2044500762`): Damage Arc, Linear Fusion Rifle (Heavy ammo by weapon type). Intrinsic Wire Rifle with the verbatim "Strong against Unstoppable Champions" line; catalyst socket = Rewind Rounds. All quoted verbatim from `docs/encyclopedia/exotics.md` (line 331) and `catalysts.md` (line 143).
Mask of Bakris text verbatim from `exotics.md` (line 39): "stacking damage bonus" applies to Stasis and Arc weapons — Queenbreaker is Arc, so it qualifies. The "stacking" magnitude and duration aren't in the encyclopedia text; treat the exact % as in-game/manifest, not stated here.
Aspects Flow State + Lethal Current and fragments Spark of Beacons/Ions/Discharge/Shock all verbatim from `aspects.md` (lines 72, 108) and `fragments.md` (lines 69–88).
Gathering Storm confirmed as the Arcstrider ranged Super (`perks.md` line 1258). Combination Blow is the standard Arcstrider charged melee but is not present as a discrete entry in our `perks.md` dump — its kill-stacks-damage/heal/refund-dodge behaviour is Arc 3.0 baseline, recorded from knowledge, not quoted from the encyclopedia. Flag accordingly; the build does not depend on it (the Shift/gun loop is self-sufficient).
Counter Energy and Amped Up verbatim from `artifact.md` (lines 54, 97); Stunning Fusion (artifact LFR Unstoppable mod) exists (line 21) but is redundant here — Queenbreaker already stuns Unstoppable intrinsically, so spend the slot on Barrier/Overload instead.
Set bonuses intentionally omitted — garnish, not a driver. Any Weapons/Class-favouring 2pc is fine if your rolls already hit the stat targets.
