Centerpiece: Symmetry (Scout Rifle · Primary · Arc) · Subclass: Arc (Arc Staff) · Role: Amplified-uptime add-clear + jolt-chain primary engine Sandbox: 9.7.0 · Updated 2026-07-03

A full-auto Arc scout that grows teeth the longer you fight. Land precision hits to bank Dynamic Charge, then dump it as homing Arc Seekers that track the priority target. The whole build is a flywheel for staying amplified — Symmetry's catalyst pays out hardest while amplified, Flow State hands you amplified for free off any jolt kill, and Mask of Bakris stacks Arc-weapon damage straight onto the scout every time you shift. Sprint, shift, jolt, repeat. The buff is never off.

The weapon

Revolution: "This weapon fires full auto. [Alternate Weapon Action]: Swap to Arc Seeker mode. Arc Seekers track toward combatants you target."

Catalyst — Eddy Current: "Temporarily increases reload speed and handling after sprinting or while amplified. This effect is improved when you are amplified."

Electric Styx (catalyst): "Increases the maximum number of Dynamic Charge stacks."

Symmetry banks Dynamic Charge from precision hits and kills in scout mode; the Alternate Weapon Action spends those stacks as Arc Seekers — homing Arc submunitions that lock onto whatever you are aiming at. More stacks means a bigger volley, and Electric Styx raises the stack ceiling so a full bank dumps harder. Revolution makes the scout full auto, which lets you pour rounds into a wave and bank charge fast. Eddy Current is the tell that this gun wants you amplified: the reload and handling bonus exists baseline after a sprint, but explicitly improves while amplified — so the build's entire job is to keep amplified live as close to 100% of the time as possible, turning a workmanlike scout into a fast-handling, quick-reloading lane primary.

Loadout

Slot	Pick	Why
Subclass	Arc (Arc Staff)	Arc element matches Symmetry so every Arc buff and surge lands on the scout; an Arc super satisfies Mask of Bakris's Shift requirement.
Super	Arc Staff	Roaming melee super for add-dense lanes; Gathering Storm is the thrown jolt-bomb alternative if you prefer burst.
Class ability	Gambler's Dodge	The keystone button — becomes a Bakris Shift, arms Lethal Current's jolt melee, and refunds melee energy on dodge.
Movement	Triple Jump	Flexible; extra aerial control to reposition between Shifts (any Hunter jump works — Strafe/High Jump to taste).
Melee	Arc charged melee (post-dodge, via Lethal Current)	After a dodge, the next melee jolts and drops an aftershock — a guaranteed jolt to seed the amplified loop.
Grenade	Flux Grenade	Sticky burst damage; swap to Pulse Grenade with Spark of Shock if you want lingering jolt area instead.
Aspect 1	Flow State	Defeating a jolted target makes you amplified — the engine that re-arms Eddy Current and opens Bakris's refund window every jolt kill.
Aspect 2	Lethal Current	After dodging, the next melee jolts and creates an aftershock, and jolted targets hit by melee are blinded — manufactures the first jolt on demand so Flow State always has a target.
Fragments	Spark of Ions · Spark of Discharge · Spark of Amplitude · Spark of Shock	Two Ionic-Trace sources + amplified-kill Orbs + grenade jolt — the reload-everything economy (see below).
Exotic armour	Mask of Bakris (Helmet)	Dodge becomes a cloaking Shift that stacks Arc-weapon damage onto Symmetry; kills with the bonus live refund class-ability energy.
Weapons	Special: Arc fusion or Arc sniper (e.g. a Voltshot/Jolting Feedback roll) · Heavy: Thunderlord	The Special keeps the Bakris Arc bonus and Spark of Discharge traces flowing and covers burst; Thunderlord is intrinsic Overload + Bolt Charge.

Fragments

Spark of Ions jolt/Bolt-Charge kills create an Ionic Trace — ability energy back
Spark of Discharge Arc weapon final blows have a chance to create an Ionic Trace — Symmetry feeds this
Spark of Amplitude rapidly defeating targets while amplified creates an Orb of Power
Spark of Shock Arc grenades jolt targets — turns your grenade into a Flow State trigger; -10 Grenade

Why it works (the mechanics)

Symmetry is Arc and Bakris buffs Arc weapons — the pairing is literal. Mask of Bakris's stacking damage bonus applies to Arc weapons after a Shift, and Clarity puts it at 10%/21%/33% at 1/2/3 stacks over an 11-second window. Symmetry is your primary, so every Gambler's Dodge Shift stacks a real damage multiplier directly onto the scout you are already firing.
The amplified flywheel never stops. Lethal Current's post-dodge melee jolts on demand → Flow State turns any jolted kill into amplified → amplified makes Eddy Current pay out its improved reload and handling on Symmetry. You manufacture the jolt (melee), it becomes a kill (scout), the kill becomes amplified, amplified makes the scout better. Self-feeding.
Dodge is the keystone — it does three jobs at once. One Gambler's Dodge (a) becomes a Bakris Shift for the Arc-damage bonus, (b) arms Lethal Current's jolt melee, and (c) refunds melee energy. Bakris also disables passive class regen but grants class energy on weapon kills while Light Shift is active — so killing with buffed Symmetry pays the dodge back and the loop funds itself.
Dynamic Charge wants sustained fire — full auto delivers it. Revolution makes Symmetry full auto, so you bank Dynamic Charge fast across a wave; Electric Styx raises the ceiling; then the AWA dump of homing Arc Seekers is your single-target/priority answer between waves. Precision uptime equals seeker uptime.
The Ionic Trace economy reloads everything. Spark of Discharge (Arc weapon kills) and Spark of Ions (jolt/Bolt-Charge kills) flood Ionic Traces; each trace tops your least-charged ability so dodge comes back faster → more Shifts → more amplified. Spark of Amplitude turns amplified rapid kills into Orbs on top, feeding the class-item vacuum.

Stats & mods

Weapons 200 → Class → Health. Weapons for raw Symmetry PvE damage (it stacks under the Bakris bonus); Class to keep Gambler's Dodge — the build's single most important button — on the shortest possible cooldown; Health as the backstop, since amplified's flinch reduction and the partial cloak on Shift cover some defence. Lean into the Weapons/Class archetype spread when picking armour.

Mods:

Boots: Arc Weapon Surge ×2 (raw Arc weapon damage straight onto Symmetry, stacking with Bakris) · Orbs of Restoration for ability energy off pickups.
Arms: Scout Rifle Loader ×2 (compounds Eddy Current's amplified handling) · Melee Font if you want Lethal Current back faster.
Chest: Arc Resistance ×2 + one off-element resist for survivability while amplified.
Class item: Powerful Attraction (dodge vacuums Orbs/traces) · Bomber (dodge → grenade energy).
Surge: Arc Surge (boots) to match the scout and Thunderlord.
Anti-Champion: Thunderlord stuns Overload intrinsically; bring an anti-Barrier source (Special roll or artifact) — Symmetry has no intrinsic champion stun.

Artifact — Slayer Baron Apothecary Satchel

This artifact bolts straight onto the build's Ionic-Trace economy and its jolt/blind/Arc core: Trace Evidence turns Symmetry's precision hits on jolted or blinded targets into the traces that reload every ability, and Retinal Burn + Arc Compounding stack a blind-then-amplify Arc damage loop. Overload is covered by Jolt and Thunderlord; bring a Barrier Special to plug the scout's gap.

Picks (2/3/2):

Tier 1: Trace Evidence · The Thick Of It
Tier 2: Retinal Burn · Curative Orbs · Debilitating Wave
Tier 3: Arc Compounding · Conductive Cosmic Crystal

Trace Evidence turns precision hits on jolted or blinded targets into Ionic Traces — the build's reload-everything engine, and Symmetry lands precision hits all day.
The Thick Of It grants Armor Charge while surrounded, fuelling Retinal Burn's consume and the Weapon Surge mods.
Retinal Burn spends a charge on Arc precision hits to blind — manufacturing the Blind that Arc Compounding keys off.
Curative Orbs makes Orbs on shield breaks, feeding Spark of Amplitude and the dodge vacuum.
Debilitating Wave emits an Arc wave on finishers, matching the Arc Staff super theme.
Arc Compounding raises Arc damage against Blind targets, pairing directly with Retinal Burn.
Conductive Cosmic Crystal adds a flat Arc damage bonus onto Symmetry's Arc payload.

Where it shines

Add-dense PvE (Vanguard Ops, Nightfalls, patrol, lost sectors): full-auto Arc scout + jolt chains + Arc Seekers clear lanes while amplified stays permanent.
Mid-range control: scout range keeps you out of melee danger while Lethal Current handles anything that closes the gap.
Champion coverage: Symmetry has no intrinsic champion stun (manifest `champion: null`). Jolt from Flow State/Lethal Current pressures Overload, and Thunderlord stuns Overload intrinsically. Bring a Barrier-capable Special or an anti-Barrier artifact mod to cover the other type.

Verify notes

Manifest-confirmed weapon facts (`data/weapon_facts.json`): Symmetry = Scout Rifle · Arc · Primary ammo · 260 RPM · champion: null (no intrinsic breaker). Element/ammo match the build; RPM and the no-champion fact are surfaced here. Thunderlord = Machine Gun · Arc · Heavy · 450 RPM · Overload — confirms the Heavy slot's Overload coverage.
Prior version corrected: the old file listed the weapon as generic "Precision" archetype and hedged Symmetry's champion type as unknown; the manifest is explicit that Symmetry has no intrinsic champion stun, so the Champion-coverage bullet now states that plainly rather than deferring to an in-game frame check.
Revolution intrinsic + Arc Seeker AWA quoted verbatim from `docs/encyclopedia/exotics.md` line 311–312. Eddy Current + Electric Styx catalyst text verbatim from `docs/encyclopedia/catalysts.md` line 133.
Mask of Bakris — Light Shift text from `exotics.md` line 39; damage numbers 10%/21%/33% at x1/x2/x3 over 11s and the "class regen disabled, weapon kills grant class energy while Light Shift active" behaviour from `docs/encyclopedia/clarity_build_numbers.md` (Mask of Bakris entry).
Dynamic Charge stack cap, per-stack seeker count and bank rate are not in the manifest — the catalyst gives the perk strings, not the numbers; Electric Styx raises the cap but the exact ceiling is unstated (flag: manifest/tuning).
Subclass pieces verified against `docs/encyclopedia/`: Flow State (`aspects.md` 73), Lethal Current (`aspects.md` 126), Spark of Ions/Discharge/Amplitude/Shock (`fragments.md` 82/72/69/87). Set bonuses deliberately omitted — garnish, not a driver (house rule).
