Necrochasm — Cursed Chain (Hunter)
Weapon: Necrochasm (Auto Rifle · Primary/Kinetic · Kinetic) · Subclass: Prismatic · Role: Precision add-clear engine that feeds an on-demand boss Super Sandbox: 9.7.0 · Created 2026-06-16
Necrochasm is a 720-RPM Adaptive auto rifle whose every precision kill spits out a Cursed Thrall bomb that corrupts the next body — and Cursed-Thrall kills refill the mag, so a dense room is one continuous trigger pull. The build does one thing with that: it converts the flood of precision final blows into Super energy through
Celestial Nighthawk, then dumps a one-shot Golden Gun on whatever the auto rifle can't chew. Kinetic kills also pour into Transcendence (Facet of Grace), so the gun pays for both your Super and your Darkness verbs.
The weapon
Cursebringer (intrinsic): "Precision final blows with this weapon increase reload speed and trigger a Cursed Thrall explosion that inflicts corruption. Final blows with Cursed Thrall explosions refill the magazine."
Catalyst — One for Thrall: "Hitting three separate targets increases damage, range, handling, and aim assist for a moderate duration."
What it does in practice: land a headshot kill → a Cursed Thrall detonation pops on the corpse, applying corruption (a chip-damage debuff) and frequently killing adjacent trash. Those explosion-kills refill the magazine — in add-dense rooms the gun never meaningfully reloads, it just chain-detonates. The catalyst is built for exactly this: tagging three separate bodies (trivial when every kill seeds an explosion) flips on a damage/range/handling/aim-assist buff, tightening the 720-RPM spray into a precision tool at mid range. It is a Primary / Kinetic weapon — no intrinsic champion stun (see Verify notes), so champions are covered by your other slots and Golden Gun.
Loadout
| Slot | Pick | Why |
|---|---|---|
| Subclass | Prismatic | Holds a Solar Golden Gun (for Nighthawk) and Kinetic-fed Transcendence off the same precision kills. |
| Super |  Golden Gun: Marksman | Nighthawk folds it into one ~big-multiplier shot — the boss/champion answer the AR can't provide. |
| Class ability |  Marksman's Dodge | Reloads the gun (redundant with Cursebringer's auto-refill, but free) and repositions between detonation chains. |
| Melee |  Threaded Spike | Returning ranged knife — ability damage with no risk of breaking your precision firing line; feeds Transcendence (Darkness). |
| Grenade |  Grapple | Mobility to reposition to the next dense pack; cheap, keeps you firing. (Swap to Arcbolt for more add-clear if you don't want the traversal.) |
| Aspect 1 |  Gunpowder Gamble | Precision kills charge a Solar throwable — the AR's kill flood builds it constantly; the detonation seeds ignitions for more add-clear and Transcendence. |
| Aspect 2 |  Stylish Executioner | Cursed-Thrall corruption is an elemental debuff → corrupted kills grant invis + Truesight, the survivability layer a Primary-gun build needs in GMs. |
| Fragments |  Facet of Grace,  Facet of Awakening,  Facet of Courage,  Facet of Bravery | See Stats & mods. |
| Exotic armour | Celestial Nighthawk (Helmet) | Hawkeye Hack: precision final blows cut Super cooldown — Necrochasm is nothing but precision final blows. One-shot Golden Gun + Super energy on its kills. |
| Kinetic |  Necrochasm | The centerpiece. |
| Energy | A Strand or Solar Special (e.g. a Slice/Heal-Clip Shotgun or Glaive) | Champion coverage + a panic button when surrounded; element feeds Bravery/Awakening verbs. |
| Heavy | A Machine Gun (or Rocket) | Boss/champion damage between Golden Guns; pick an archetype covering a champion type you lack. |
Why this works (the mechanics)
- The gun is a precision-kill firehose, and every system here taxes that firehose. Cursebringer turns one headshot kill into an explosion that makes the next kill, which refills the mag, which makes the next explosion. In a room of adds you produce precision/explosion final blows faster than almost any Primary in the game — that kill-rate is the resource everything else spends.
- Celestial Nighthawk monetises that kill-rate into Super. Hawkeye Hack reduces Golden Gun's cooldown on precision final blows — the only kind Necrochasm makes when you're aiming. You charge a one-shot, ~massive-multiplier Golden Gun off add-clear you were doing anyway, then spend it on the boss, champion, or miniboss the auto rifle isn't built to delete. The gun and the Super are the same loop.
- Facet of Grace double-dips the Kinetic kills into Transcendence. Necrochasm is Kinetic, so its kills grant bonus Light Transcendence energy. The precision-kill flood that's charging Golden Gun is simultaneously charging the Transcendence bar — and Transcendent grenade/melee get the standard damage bump. One trigger pull, three meters filling (mag, Super, Transcendence).
- Cursebringer's corruption is an "elemental debuff," so Stylish Executioner fires off it. Corrupted-target kills grant invisibility + Truesight. That is the safety valve for a build whose damage is a Primary auto rifle: when a room turns on you, a corrupted kill (you make these nonstop) drops you off radar. No Void subclass required — corruption counts.
- Gunpowder Gamble is charged purely by precision kills. Same input again: the AR's headshot kills build the Solar explosive. Throw it into the next pack → ignitions → more kills → more Cursebringer chains → more Super/Transcendence. It's an add-clear amplifier wired to the exact thing the gun already does.
- One for Thrall keeps the spray honest at range. A 720 Adaptive AR is twitchy past mid; the catalyst's hit-three-targets buff (damage/range/handling/aim assist) is effectively always-on in adds and pulls the gun's effective range out to where Hawkeye Hack precision kills stay reliable.
Stats & mods
Weapons 200 → Super → Health → Class. Weapons is the priority — it's the PvE damage multiplier that rides on top of Cursebringer and One for Thrall for the whole build's output. Super second to cycle Nighthawk Golden Gun faster (Hawkeye Hack already accelerates it). Health/Class as needed for survivability and dodge uptime.
Fragments (4):
- Facet of Grace — Kinetic kills → bonus Transcendence; Super kills → team Transcendence. (−10 Health.) The reason the Kinetic gun feeds your Darkness side.
- Facet of Awakening — rapid Light/Darkness/Super kills → elemental pickups (more Transcendence + ability energy fuel). (+10 Health, offsets Grace.)
- Facet of Courage — Arc/Solar/Void abilities deal more damage to Darkness-debuffed targets (Gunpowder Gamble ignites land harder). (+10 Grenade.)
- Facet of Bravery — grenade/melee kills grant Volatile/Unraveling Rounds to your Void/Strand weapons — buffs the Special slot if you run Void or Strand. (Swap for Facet of Honor if your other weapons are Solar/Stasis.)
Mods (standard armour mods — names from the knowledge base; see Verify notes):
- Helmet: Kinetic Siphon (AR kills → Orbs) · Ashes to Assets (Super on ability kills).
- Arms: Auto Rifle Loader ×2 (free, given the auto-refill, route to Heavy instead if preferred) · Momentum Transfer.
- Chest: elemental resist ×3 (flat DR under invis).
- Legs: Kinetic Weapon Surge ×2 (≈+17% Necrochasm damage) · Orbs of Restoration.
- Class item: Powerful Attraction (dodge vacuums orbs) · Bomber/Outreach for ability uptime.
Artifact (knowledge base): 
Targeting Autoloader (AR kills reload your stowed weapons + buff AR damage — keeps the Special/Heavy topped while you spray) and 
Sustained Fire (40% DR on consecutive AR hits — survivability that turns on the instant you start firing, perfect for a hold-the-trigger gun). Add 
Radiant Orbs/Galvanic-style pickups as slots allow.
Where it shines
- Add-dense PvE — Vanguard Ops, Nightfalls, the clear phases of raids/dungeons, Onslaught. This is the gun's home: the more bodies, the longer the Cursebringer chain runs and the faster Golden Gun and Transcendence charge.
- GM Nightfalls — survivability is real here (Stylish invis + Sustained Fire DR + Nighthawk's panic-button Super), and the one-shot Golden Gun is your champion/miniboss executioner.
- Champion coverage: Necrochasm itself stuns nothing (Primary Kinetic, no bespoke stun). Cover champions with (a) Golden Gun as a raw delete, (b) your Special and Heavy archetypes — pick frames covering the Barrier/Unstoppable/Overload split you need (Aggressive/High-Impact → Unstoppable; Precision/Adaptive → Barrier; Lightweight/Rapid-Fire → Overload), and (c) Gunpowder Gamble ignitions / corruption chip to soften them. Slot artifact champion mods to match.
