Outbreak's whole fantasy is a self-feeding plague: rapid hits and precision kills spit out SIVA nanite swarms, the swarms kill, the catalyst makes the dead spawn more swarms. It only stops if you stop shooting — so the build's entire job is "never stop shooting." A Void Hunter wrapped in Gyrfalcon's runs an invisibility→Devour→finisher loop that keeps you alive, keeps you killing, and keeps the nanite cascade rolling through an entire room.

The weapon

The Corruption Spreads: This weapon creates SIVA nanite swarms on rapid hits and precision kills.

Catalyst — Disease Vector: Increases nanite damage. Enemies that die with nanites attached to them generate additional nanites.

A 450 RPM Rapid-Fire Kinetic pulse. The nanites are the point: land rapid hits or a precision kill and a swarm spawns that seeks and chews on nearby targets. With the catalyst, anything that dies while infested coughs up a fresh swarm — so in a pack, one infested kill chains into the next into the next. It is one of the best sustained primary add-clear tools in the game precisely because the damage keeps spreading after you've moved your reticle on. Outbreak does not carry a bespoke champion stun and a Rapid-Fire pulse has no intrinsic anti-champion archetype (see Anti-Champion note), so champion duty is farmed out to the artifact and the other two slots — Outbreak is the engine that clears everything around the champion.

Loadout

Slot	Pick	Why
Subclass	Nightstalker (Void)	The invis + Devour + Volatile toolkit that keeps you firing forever.
Super	Shadowshot: Deadfall	Tether groups + 35% weaken when a pack or champion needs deleting; cheap, team-wide.
Class ability	Marksman's Dodge	Reloads Outbreak on demand mid-fight — keeps the nanite stream uninterrupted.
Melee	Snare Bomb	Smoke → weaken/suppress; the debuff that arms Stylish Executioner for free invis.
Grenade	Vortex Grenade	Lingering Void AoE — pairs with Echo of Instability for Volatile and feeds finisher-fuel kills.
Aspect 1	Stylish Executioner	Any elemental-debuffed kill → Invisibility + Truesight. Outbreak kills near smoke/volatile/weaken trigger this constantly.
Aspect 2	Vanishing Step	Dodge → Invisibility. Guaranteed on-demand invis to re-arm Gyrfalcon's and the Devour loop.
Fragments	Echo of Persistence · Echo of Starvation · Echo of Harvest · Echo of Instability	Longer invis/Devour; Orb/Breach → Devour; weakened kills → Orb + Breach; grenade kills → Volatile.
Exotic armour	Gyrfalcon's Hauberk (Chest)	Finisher-while-invis → fireteam reserve overshields + all-weapon damage; invis-exit → Volatile on the Void secondary.
Energy weapon	A Void Special (e.g. a Repulsor Brace / Destabilizing fusion or shotgun)	Soaks Gyrfalcon's Volatile, makes Volatile detonations, double-procs Stylish/Harvest.
Heavy	Machine Gun or LFR	The thing Outbreak's swarms can't personally execute — bosses, mini-bosses, the champion.

Why this works (the mechanics)

Outbreak is a kill machine; the build is a never-die machine. Outbreak's nanite cascade only pays out while you keep landing hits and precision kills. Everything below exists to keep you alive and reloaded so the stream never breaks — survivability is the damage uptime.
The free-invis loop runs off Outbreak's own kills. Snare Bomb (or Vortex) debuffs a pack → an Outbreak/nanite kill on a debuffed target triggers Stylish Executioner → Invisibility + Truesight. No finisher, no dodge needed — just kill something that's debuffed, which in a smoked/volatile pack is constant.
Devour is the sustain spine. Echo of Harvest turns weakened kills (Deadfall, Snare Bomb) into an Orb and a Void Breach; Echo of Starvation converts either pickup into Devour (full heal on kill + grenade energy). So Outbreak-fed kills heal you to full on a loop while topping the grenade that re-arms Volatile. Echo of Persistence stretches invis + Devour so the windows overlap instead of gapping.
Gyrfalcon's is the team-buff + DR garnish. Finishing while invisible grants you and nearby allies reserve overshields (deployable on class ability) + bonus all-weapon damage. Vanishing Step guarantees the invis; Outbreak feeds the finisher kills. Honest caveat: Gyrfalcon's Volatile Rounds land on Void weapons only, so they buff the secondary — not Kinetic Outbreak. Outbreak's gain from Gyrfalcon's is the all-weapon finisher damage buff and the overshield layer, not Volatile.
Volatile is the secondary's job and it loops back to invis. Echo of Instability (grenade kills) and Gyrfalcon's (invis-exit) both grant Volatile to the Void Special; Volatile detonations are Void debuff kills → more Stylish invis → more Devour. The Void half of the kit recharges the survivability the Kinetic half spends.
The orb economy keeps Super and Devour flush. Harvest floods Orbs + Breaches off weakened kills; Starvation eats them for Devour; Deadfall returns cheaply because tethered packs die fast under nanites. You are never out of heal, invis, or Super for long.

Stats & mods

Weapons 200 → Health 100+ → Class. Weapons buys flat PvE damage on Outbreak's body shots and nanite chip (it scales the weapon-damage stat that 9.7.0 made matter for minors/majors); Class feeds dodge uptime to re-arm invis and reserve overshields; Health as the comfortable floor since Devour + overshields already carry survivability.

Archetypes: lean Weapons/Class pieces (Gunner / Specialist favouring Weapons).

Mods, by piece:

Helmet: Harmonic Siphon (Void) — keeps Orbs flowing for Starvation/Devour; Heavy Ammo Finder for the boss gun.
Gauntlets: Pulse Rifle Loader ×1–2 (snappier Outbreak reloads between dodges) · Kinetic Weapon Surge if you prefer raw Outbreak damage over reload.
Chest (Gyrfalcon's): Arc/Solar/Void Resistance to taste under the overshield layer.
Boots: Kinetic Weapon Surge ×2 (≈+17% Outbreak damage — straight onto the centerpiece) · Orbs of Restoration (orb pickup → ability energy).
Class item: Powerful Attraction (dodge vacuums orbs into the Starvation loop) · Reaper (dodge → next kill spawns an extra Orb).
Champion mods: slot the artifact's anti-Barrier/Unstoppable/Overload mods (see Anti-Champion 2.0) — Outbreak itself carries no intrinsic stun.

Where it shines

GMs / Master content / endgame add-clear: Outbreak + catalyst is among the best sustained primary room-clears in the game; the nanite chain thrives in dense rooms, and the invis/Devour loop is the survivability GMs demand.
Onslaught / wave defence / Nightfalls: packs are constant, so Stylish invis and the Harvest orb-flood never stall.
Champion coverage: none intrinsic to Outbreak. A Rapid-Fire pulse has no archetype stun, so coverage comes from (a) artifact anti-champion mods, (b) the Void Special / Heavy you bring, and (c) Deadfall's suppress + Snare Bomb's weaken to neutralise champion behaviour. Outbreak clears the champion's escort; the heavy and stun source kill the champion.

Verify notes

Element/ammo: manifest (`inspect_item.py`) confirms Rapid-Fire Pulse Rifle, 450 RPM, Primary but does not print a damage-type field — Outbreak Perfected is Kinetic (longstanding, recorded here from game knowledge, not from an element field in our snapshot). Flagging per instructions.
Exotic perk + catalyst: verbatim from `docs/encyclopedia/exotics.md` line 284 (The Corruption Spreads) and `docs/encyclopedia/catalysts.md` line 110 (Disease Vector). Exact nanite damage numbers / swarm counts are not in the encyclopedia — behaviour only.
Gyrfalcon's Hauberk (See Me, Feel Me), Stylish Executioner, Vanishing Step, and all four Echoes verified verbatim against `docs/encyclopedia/` (exotics.md, aspects.md, fragments.md). Note the explicit caveat in §4: Gyrfalcon's Volatile is Void-weapon only, so it does not buff Kinetic Outbreak — Outbreak gains the finisher all-weapon damage buff + overshield, not Volatile.
Mods: `docs/encyclopedia/mods.md` is thin (mostly legacy glimmer scavengers); Siphon / Surge / Loader / Resistance / Orbs of Restoration / Powerful Attraction / Reaper are standard 9.7.0 combat mods drawn from `docs/knowledge/buildcrafting_framework.md` ("weapon-type surge/loader/ scavenger, champion mods") and the house-style reference builds — not re-verified line-by-line against the manifest mod dump.
Anti-Champion 2.0: Outbreak carries no bespoke stun and Rapid-Fire pulse is not a stun archetype — champion duty is intentionally offloaded to the artifact + secondary/heavy. Confirm the active artifact's champion mods in-game.
Set bonuses deliberately omitted — garnish, never a driver (house rule). Any 2pc/4pc that adds Weapons/Class stat or Void uptime is a fine optional layer.
