Centerpiece: Balance of Power (Leg Armor) · Subclass: Threadrunner · Role: Threadling-fountain add-clear that winds a dual-exotic Euphony to its damage ceiling, then dumps the linear fusion into the boss Sandbox: 9.7.0 · Updated 2026-06-29

Dodge to drop a tougher Threaded Specter that bleeds Perched Threadlings, then let the swarm chew the room while every threadling hit winds Euphony toward its damage ceiling. Tangles feed Whirling Maelstrom, the linear fusion re-seeds its own swarm through Unwound, and Particle Reconstruction turns the wound-up rifle loose on the boss. The Specter eats the aggro; you stay off radar and feed the fountain.

The exotic

Double Down: Your Threaded Specter has increased duration and durability, and damaging it releases additional Threadlings. While near your Threaded Specter, you do not appear on radar.

Euphony — Unwound: Dealing sustained damage with this weapon spawns Threadlings at your target's location. Spindle (exotic trait): Threadling damage increases this weapon's damage. Catalyst — Enlightened Action: Dealing damage improves reload speed and handling.

This is a legal dual-exotic — one armour, one weapon — and the two halves are supplier and consumer of the same threadlings. Balance of Power turns the Threaded Specter from a throwaway decoy into a threadling battery: Clarity puts it at 50% [25% PvP] damage resistance (bypassed by your own damage), +34% duration, and 2 Perched Threadlings that release when the Specter takes 40 damage (both dump when it dies). Stand within 15 m and you gain Hidden — off radar — while the Specter soaks the room's fire. The cost is real: casting your class ability cuts class-ability regen by 50% for 19 s, so the build leans on a high Class stat to keep Specters flowing. Euphony is the consumer — Spindle converts every threadling hit into stacking weapon damage, Unwound makes the rifle re-seed its own threadlings on sustained fire, and the catalyst keeps it reloading. The Specter and grenade make the swarm; Euphony eats it.

Loadout

Slot	Pick	Why
Subclass	Threadrunner (Strand)	Strand's Threadling / Tangle / Sever verbs plus the dodge-centric aspects that turn the class ability into the swarm engine.
Super	Silkstrike	Strand rope-dart Super for add-sweep and a panic clear; Elemental Supercharger (artifact) refunds Super energy off severed kills, so it comes back fast.
Class ability	Gambler's Dodge	Spawns the Threaded Specter (the engine) and refunds melee for Threaded Spike. Boss phase: swap to Marksman's Dodge to reload Euphony on dodge.
Movement	Triple Jump (flex)	Air control to reposition — not load-bearing, player preference.
Melee	Threaded Spike	Returning rope-dart that severs; severed Strand kills feed Elemental Supercharger and the Tangle economy, and Gambler's keeps it charged.
Grenade	Threadling Grenade	Throws threadlings directly — the fountain's grenade half, refilled fast by Thread of Generation. Champion content: swap to Shackle Grenade for Suspend.
Aspect 1	Threaded Specter	Required — Double Down only buffs the Specter. Each dodge drops a decoy that draws fire and detonates into Threadlings when hit hard or when foes approach.
Aspect 2	Whirling Maelstrom	Destroying a Tangle weaves a roaming Strand mass that damages targets and emits Unravelling projectiles — which then feed the artifact's Horde Shuttle. _[+2 Aspect Energy]_
Fragments	Evolution · Rebirth · Generation · Ascent	More threadling damage/range, Euphony re-seeding the swarm, grenade refill, and a Euphony reload on every grenade cast.
Exotic armour	Balance of Power (Leg Armor)	Turns the Specter into a tanky, longer-lived threadling battery with 2 Perched Threadlings, and keeps you off radar within 15 m.
Weapons	Euphony (Strand LFR · Special) + kinetic add-clear primary + Strand Hatchling heavy	Euphony is the boss weapon and swarm seeder; the kinetic clears chaff and farms Special bricks; the Strand heavy piles more bodies into the swarm.

Fragments

Thread of Evolution Threadlings travel farther and deal additional damage — Clarity: 33% more in PvE; +10 Super
Thread of Rebirth Strand weapon final blows have a chance to create a Threadling — Euphony re-seeds the swarm
Thread of Generation dealing damage generates grenade energy — refills the Threadling Grenade; −10 Grenade
Thread of Ascent (grenade cast reloads your equipped weapon plus bonus airborne effectiveness and handling; +10 Weapons). Defensive swap: Thread of Warding (Orb pickup → Woven Mail; −10 Health) if you want survivability beyond the Specter's aggro-soak**

Why it works (the mechanics)

The Specter is a threadling battery, not just a decoy. Double Down stacks +50% DR, +34% duration and 2 Perched Threadlings onto it. The Perched pair release when the Specter takes 40 damage, and the aspect's native detonation throws more when it dies or enemies close — so one dodge produces a cluster of threadlings without spending the grenade.
Threadling damage ramps the rifle. Euphony's Spindle intrinsic is literally "Threadling damage increases this weapon's damage": the swarm Balance of Power produces passively winds the linear fusion up before the boss phase, so you don't grind the stacks by hand — the Specter and grenade do it for you.
Euphony refills its own fuel. Unwound spawns Threadlings at your target on sustained fire, and Thread of Rebirth rolls a Threadling on Strand weapon final blows — so firing Euphony produces the threadlings that produce its Spindle stacks. Consumer and supplier are the same weapon, and Enlightened Action keeps it reloaded through the loop.
Tangles convert the overflow. Rapid Strand/threadling kills drop Tangles; Whirling Maelstrom turns each destroyed Tangle into a roaming Strand mass that damages and emits Unravel projectiles. Unravelled targets then feed the artifact's Horde Shuttle (spawns more Threadlings, which sever) — the swarm regenerates itself two ways.
The artifact is built for a linear fusion. Particle Reconstruction partially refills Euphony's magazine from reserves and grants bonus sustained damage to a single target — the standard linear-fusion boss-DPS multiplier — while Elemental Supercharger turns severed Strand kills back into Silkstrike energy for an add reset.
You vanish while the Specter eats aggro. Within 15 m of the Specter you are Hidden (off radar), and its +50% DR makes it the thing enemies shoot. That aggro-soak is the build's survivability in place of a damage-resist exotic.

Stats & mods

Class 200 → Weapons → Grenade. Class leads because Double Down halves class-ability regen for 19 s every cast — you want a high Class floor just to keep Specters online, and Threaded Specter's damage scales with Class above 100. Weapons is Euphony's boss output (the stat that stacks under Spindle + Particle Reconstruction). Grenade keeps the Threadling Grenade looping; Super can ride low since Elemental Supercharger refunds it. Treat the numbers as planner targets — run `stat_optimiser.py --validate` / `my_stats.py` to fit them to real armour.

Mods:

Boots: Class Font ×2 (+40 Class while Armor Charged) to claw back Double Down's −50% class regen so Specters keep flowing · Recuperation (Orb pickup → health).
Arms: Grenade Font ×2 (+40 Grenade) to keep the Threadling Grenade looping · Strand Loader.
Chest: elemental resist mods to taste — the flat damage-resist layer beneath the Specter's aggro-soak.
Class item: Powerful Attraction (dodge vacuums Orbs into Armor Charge) · Class Font · Strand Siphon (Strand kills → Orbs that feed the fonts).
Surge: Strand Weapon Surge to push Euphony's damage while Armor Charged; pair Super Font on the helm if you want Silkstrike up more often.
Anti-Champion: none innate — Tablet of Ruin carries no champion mod, so cover Unstoppable + Overload via Suspend (Shackle Grenade / Ensnaring Slam); bring an Anti-Barrier legendary or lean on the team for Barrier.

Artifact — Tablet of Ruin

Picks (2/3/2): Unraveling Orbs + Elemental Siphon — Horde Shuttle + Vile Weave + Gold From Lead — Particle Reconstruction + Elemental Supercharger

Tablet of Ruin is the one artifact themed for Linear Fusion + Strand + Threadling + Tangle, so every pick feeds Euphony's loop rather than a generic subclass.

Particle Reconstruction (T3) is the Euphony boss-DPS engine — mag-refill from reserves plus bonus sustained damage against the target you're holding on.
Elemental Supercharger (T3) turns severed-target Strand kills back into Silkstrike energy, so the add-clear Super refunds itself. Alt: To Shreds here if you want Woven Mail over Super uptime.
Horde Shuttle (T2) is the threadling fountain — damaging Unravelled targets spawns Threadlings that sever, which then feed Spindle and the Tangle economy.
Vile Weave (T2) severs Tangle-hit targets and cuts the Tangle cooldown on pickup → more Whirling Maelstrom and more severed kills for Elemental Supercharger.
Unraveling Orbs (T1) gives Strand weapons Unravelling Rounds off Orb/Tangle pickups, seeding the Unravel that Horde Shuttle consumes.
Elemental Siphon (T1) makes Strand (Super-matching) kills create matching pickups, and Gold From Lead (T2) converts your Special-ammo pickups into Heavy to keep the Strand heavy fed.

Where it shines

Boss-DPS phases — Euphony arrives at the damage phase already wound up by the swarm, with Particle Reconstruction refilling the mag from reserves; this is the build's payoff window.
Add-dense rooms — the Specter, Threadling Grenade and Whirling Maelstrom flood the floor with seeking threadlings, and severs/Tangles regenerate the swarm without manual upkeep.
Solo/duo content where you need to disappear — Hidden within 15 m of the Specter plus its +50% DR makes the decoy, not you, the target.
Champion coverage: no intrinsic break — cover Unstoppable + Overload via Suspend (Shackle Grenade / Ensnaring Slam); Barrier has no innate answer (Euphony's burst breaks the shield by raw damage but won't stun the recharge), so bring an Anti-Barrier flex or lean on the team.

Verify notes

Manifest-confirmed facts: Euphony is Strand · Special · Linear Fusion Rifle with no intrinsic Champion breaker (`data/weapon_facts.json`). Double Down, Unwound, Spindle and the Enlightened Action catalyst are verbatim from `exotics.md` / `exotic_intrinsics.md` / `perks.md` / `catalysts.md`; Threaded Specter + Whirling Maelstrom from `aspects.md`; the four fragments from `fragments.md`; the Tablet of Ruin 2/3/2 pool from `artifacts_structured.md`.
Double Down numbers (`clarity_build_numbers.md`): 50% [25% PvP] DR (bypassed by your damage), +34% duration, 2 Perched Threadlings (release at 40 damage taken; destroying the Specter releases both), 15 m Hidden, class-ability regen −50% for 19 s per cast.
Thread of Evolution (`clarity_build_numbers.md`): 33% [12.5% PvP] increased threadling damage, ~30% faster — Clarity flags the speed figure with "?".
Spindle's exact ramp (commonly cited as +2% per stack, max 25 = +50% Euphony damage) is not in the project encyclopedia — `perks.md` gives only the qualitative "Threadling damage increases this weapon's damage" and there is no Clarity entry. The interaction is confirmed; treat the +50% ceiling as manifest/tuning and verify in-game.
Unwound's trigger detail (commonly cited as precision kill → 1 Threadling, or 6 hits in ~3 s → 3 Threadlings) is not in the project encyclopedia — the manifest text is only "Dealing sustained damage with this weapon spawns Threadlings at your target's location." Qualitative behaviour confirmed; exact hit counts/timers unverified.
Silkstrike, Whirling Maelstrom and the artifact perks have no Clarity entry (supers/artifact perks aren't covered) — treat the Super-energy refund and Elemental Supercharger magnitudes as in-game-verify.
Champion limitation: Tablet of Ruin has no anti-Champion mod in the project data; this build covers Unstoppable/Overload only through Suspend, and Barrier needs a flex weapon or the team.
