Centerpiece: Euphony (Linear Fusion Rifle · Special · Strand) · Subclass: Strand (Threadrunner) · Role: Threadling spawner / sustained-DPS that ammos its own ad-clear Sandbox: 9.7.0 · Updated 2026-07-03
A Linear Fusion that pays you in bugs. Hold the beam on anything big and Euphony births Threadlings at the target — and on Strand Hunter those Threadlings unravel (Swarmers), feed your Super (Weaver's Call), and tighten the whole Tangle/Woven-Mail economy. You aim the LFR at the boss for DPS; the swarm you spawn clears the room you weren't looking at. Two playstyles, one trigger.
The weapon
Unwound (intrinsic):"Dealing sustained damage with this weapon spawns Threadlings at your target's location."
Catalyst — Enlightened Action:"Dealing damage improves reload speed and handling."
Euphony is a Strand Linear Fusion Rifle that does two jobs at once. As an LFR it's a precision damage stick into a boss crit spot; the sustained clause in Unwound means staying on a single target — exactly what an LFR does to a major or boss — keeps spitting Threadlings out at the point of impact, so the swarm spawns on the priority target, not at your feet. No other Threadling source does this at range. The catalyst (Enlightened Action) plasters over the LFR's two weaknesses — slow reload and clumsy handling — every time you land a shot, so the gun-ready / swap loop stops fighting you. The Threadlings are the build; the LFR damage is the delivery mechanism that spawns them on the right enemy.

Why
Subclass
Strand — Threadrunner
Only subclass that turns Euphony's free Threadlings into a damage and Super and defensive economy.
Super
Silkstrike
Roaming Strand Super, refunded fast by the Threadling/Tangle flood; swap to a Suspend Super if you want grouping instead.
Class ability
Acrobat's Dodge
Triggers Weaver's Call — three Threadlings on demand on top of Euphony's — and refreshes on melee.
Movement
Triple Jump
Extra mid-air correction to keep line-of-sight on a crit spot while charging the LFR.
Melee
Threaded Spike
Bouncing melee makes kills and Tangles → more Threadlings → returns melee energy.
Grenade
Threadling Grenade
Direct Threadling injection; stacks with Euphony's swarm for the room you're ignoring.
Aspect 1
Weaver's Call
Class ability weaves 3 Threadlings and deploys perched ones; Euphony's sustained fire perches a reserve constantly.
Aspect 2
Whirling Maelstrom
Destroying a Tangle weaves a Strand mass that seeks targets and emits Unraveling projectiles on kills — turns the Tangle flood into autonomous ad-clear.
Fragments
Thread of Evolution · Thread of Rebirth · Thread of Generation · Thread of Warding
Pump Threadling damage + spawn rate + the grenade/defence economy off the same gunfire.
Exotic armour
Swarmers (Leg Armor) — "Destroying a Tangle spawns a Threadling. Your Threadlings unravel targets that they damage."
THE Threadling exotic: every Threadling Euphony makes now unravels what it hits, and your Tangles mint more Threadlings.
Weapons
Strand primary (Unravel-capable auto/SMG) + a Heavy for boss phases
The primary procs Thread of Rebirth and builds Tangles to feed Swarmers/Whirling Maelstrom between Euphony shots; the Heavy covers big damage windows since Euphony sits in the Special/energy slot.
Fragments
Thread of Evolution · Thread of Rebirth · Thread of Generation · Thread of Warding
Why it works (the mechanics)
Euphony spawns Threadlings on the target, not on you. Unwound keys off sustained damage — the LFR's natural behaviour against a major or boss — and drops the Threadlings at the impact point. You point it at the thing that matters and the swarm spawns there.
Swarmers makes every one of those Threadlings a debuff."Your Threadlings unravel targets that they damage." Unravel is a damage-over-time plus a debuff that boosts incoming weapon damage, so Euphony's free swarm is also softening everything for the whole fireteam, not just chipping it.
Weaver's Call closes the loop with almost no APM. Every Euphony shot and every Threadling kill banks a perched Threadling, then your dodge weaves three plus the perched reserve. You are constantly carrying a queued swarm that one button dumps.
Tangles convert the swarm into a self-running second swarm. Swarmers spawns a Threadling whenever a Tangle dies; Whirling Maelstrom turns a destroyed Tangle into a seeking Strand mass that fires Unraveling projectiles on kills. Your Strand primary and Threaded Spike manufacture Tangles, so the floor stays covered while you keep the LFR on the boss.
The fragments pay the gun's own tax. Thread of Evolution makes the free Threadlings actually hurt (+10 Super); Thread of Generation turns Euphony fire into grenade energy → more Threadling Grenades; Thread of Rebirth gives Strand-weapon final blows a second Threadling-spawn roll; Thread of Warding turns the Orbs you generate into Woven Mail. Every line is fed by pulling the trigger.
The catalyst removes the LFR penalty box. Enlightened Action restores reload and handling on every hit, so the slow, clumsy LFR stops punishing the swap-heavy rhythm this build wants (LFR on boss → primary for Tangles → dodge to dump Threadlings).
Stats & mods
Super 200 → Weapons → Grenade. Threadling damage scales off the Super stat treatment via Thread of Evolution's payout and you want Silkstrike back fast; Weapons buoys Euphony's per-shot LFR damage; Grenade keeps Threadling Grenades flowing. Health is the dump stat — Woven Mail (Thread of Warding) plus constant spacing cover survivability.
Boots: Strand Weapon Surge ×2 · Special Ammo Finder.
Arms: Grenade Kickstart · Special Ammo Scavenger.
Chest: elemental resists to taste.
Class item: Powerful Attraction (dodge vacuums Orbs) · Time Dilation.
Surge: Strand Weapon Surge (single-element to buff Euphony).
Anti-Champion: none intrinsic — cover via Suspend (see Where it shines).
Artifact — Implement of Curiosity
The Strand-native artifact for a Threadling/Tangle engine: it pays off the Unravel, Tangle, and Woven Mail this build floods but never spends, and covers Unstoppable through the swarm itself (Pack Tactics' max-stack Threadlings) — with no Overload mod in the pool, the rest of champion duty leans on Suspend.
Horde Shuttle makes unraveled targets spawn severing Threadlings — it feeds the swarm off Euphony's own Unravel, so the gun's debuff loops back into more bugs.
Pack Tactics ramps Threadling damage and, at max stacks, lets Threadlings stun Unstoppable — champion coverage from the build itself.
Threaded Blast widens the explosion when you destroy a Tangle with Strand, paying off the Tangle flood Threaded Spike and your primary generate.
Elemental Daze turns a Champion stun you land with a Strand weapon into a matching elemental debuff explosion that spreads to nearby targets — it amplifies a stun rather than supplying one (it does not stun Champions itself).
Elemental Coalescence makes defeated targets drop Strand pickups that feed Overdrive.
Elemental Overdrive turns a Strand pickup or Tangle into increased Strand damage — a direct DPS bump for Euphony.
Tangled Web suspends nearby foes off a Tangle from a Strand-debuffed kill — the build's Suspend/grouping payoff, fed by Unravel.
Where it shines
Add-dense PvE (GMs, Legend content, Nightfalls): the spawn-on-target swarm + Whirling Maelstrom + Swarmers runs a whole second source of ad-clear while you treat priority targets with the LFR, and Unravel softens the fireteam's damage profile.
Major / boss damage windows: it's still a Linear Fusion — park crits into a boss for real Special-slot DPS, and the Threadlings it sheds peel the adds that would otherwise interrupt the phase.
Champion coverage: Euphony carries no intrinsic champion stun (Unwound names none, and manifest lists its champion field as empty). Cover champions with Suspend (Shackle Grenade / Tangled Web / a Suspend Super) for Unstoppable- and Overload-style control, plus Pack Tactics' max-stack Threadling Unstoppable stun; Unravel chips champion health for the team.
