Two knives per charge, and every kill stacks a damage bonus on the next throw. This isn't the precision build and it isn't the ignition build — it's the juggle: keep knives in the air, keep the stack alive with a well-timed dodge, and watch each throw land harder than the last. The longer the fight runs, the more it hurts.
The exotic
Scissor Fingers: Gain a second knife per charge. Getting a final blow with a throwing knife grants consecutive knives a temporary stacking damage bonus. Gambler's Dodge refreshes the bonus timer.
Three clauses, three payoffs. The first — a second knife per charge — doubles your throw count before any refund even fires; Clarity confirms it as an extra Solar melee charge with all charges recharging simultaneously, so you never wait on one to top up the other. The second — a stacking damage bonus on throwing-knife final blows — makes the build get stronger the longer you stay in a fight, the opposite of a burst kit. The third — Gambler's Dodge refreshes the timer — means the stack is yours to keep through a lull: no kills to feed it, dodge to hold it, then resume at the held bonus. The chest slot also frees your gauntlets for a Heavy-Handed / mobility roll instead of a second knife exotic.
Loadout
Slot
Pick
Why
Subclass
Gunslinger (Solar)
Solar throwing knives scorch on hit, feeding Ember of Searing's refund and the whole Radiant→Scorch→Ignition spine.
Super
Blade Barrage
An on-theme volley of Scorching knives, and Knock 'Em Down makes it launch more projectiles.
Class ability
Gambler's Dodge
Mandatory — refunds melee energy near enemies (scaled by Melee) and refreshes Ophidia's stack timer; the build pivots on it.
Movement
Triple Jump
Extra aerial adjust to reposition between throws and line up the next pack; flex to Strafe Jump if you prefer.
Melee
Lightweight Knife
The fastest-recharging single throwing knife — max throws per minute = max stacks, and Ophidia doubles it to two per charge.
Grenade
Healing / Tripmine
Flex; the knives are the build. Healing for survivability, Tripmine for a Solar-debuff kill if you want it.
Aspect 1
Knock 'Em Down
While Radiant, Throwing Knife final blows fully refund melee energy — and it buffs Blade Barrage's projectile count.
Aspect 2
On Your Mark
Class-ability use and precision hits grant stacking Weapons + reload (×10); knife crits and Gambler's Dodge both feed it.
Fragments
Searing · Ashes · Torches · Solace · Eruption
Two refund streams (Searing off-Radiant, Torches→Radiant→Knock 'Em Down) plus scorch/ignition density.
Exotic armour
Ophidia Spathe (Chest)
Second knife per charge + the stacking damage ramp; the whole loop is built on Scissor Fingers.
Weapons
Solar Incandescent primary · precision Solar frame · Rocket Launcher
Incandescent spreads scorch between throws; the Rocket carries the artifact's champion/boss mods.

Why it works (the mechanics)
Volume is the whole point, so pick the fastest knife. Ophidia rewards number of throws (two per charge) and number of kills (each stacks the bonus), so the melee choice is whichever recharges fastest and throws cleanest: Lightweight Knife. Knife Trick (fan of three) and Weighted Knife (precision bounce) are the other-build variants; for pure stacking spam the single fast knife wins.
The stack is a ramp, not a window — Gambler's keeps it open. Throwing-knife final blows climb the bonus to +30% / +60% / +200% knife damage after 1 / 2 / 3 kills (Clarity), and it decays on a five-second timer. Gambler's Dodge refreshes that timer for free, so the loop is throw → kill → stack, and if kills dry up you dodge to hold the stack, then throw again at the held bonus. You never rebuild from zero.
Two independent refund streams keep both knives airborne. Off-Radiant, Ember of Searing refunds melee on scorched-target kills (your Solar knife scorches, so most kills qualify) plus a Firesprite. While Radiant, Knock 'Em Down fully refunds melee on Throwing Knife final blows. Ember of Torches makes you Radiant off the powered melee itself, so the two streams hand off — Searing covers the ramp-up, Knock 'Em Down covers the Radiant windows.
Density is your damage stat. Scorch from each knife plus Ember of Eruption's wider ignitions mean one throw into a pack chains kills to neighbours — and every kill is one more stack on the next knife. The build literally compounds against grouped adds, and Ember of Ashes accelerates the scorch that triggers it.
On Your Mark rides along free. Knife precision hits and every Gambler's Dodge feed its ×10 Weapons/reload stacks, so your gun sharpens on the same inputs that drive the knives — and at ten stacks, final blows cure you, adding sustain the grenade slot doesn't have to.
Blade Barrage is the room-delete valve. Knock 'Em Down makes the Super launch more projectiles, and it inherits Solar's scorch/ignition — when a pack is too big to juggle, the same aspect that fuels your knives turns the volley into a wall of ignitions.
Stats & mods
Melee 200 → Class → Weapons. Melee 200 maxes throw recharge and boosts Gambler's melee refund (which scales with Melee); Class keeps Gambler's Dodge — your stack-refresh button — up as often as possible; Weapons third for the Incandescent feeder and On Your Mark synergy. Archetype lean: Skirmisher (Melee/Weapons) and Brawler (Melee) as the spine, Reaver (Class/Melee) to prop up Class.
Mods:
Boots: Melee Kickstart ×2 — refunds a chunk of melee energy when you throw on empty, covering the gap between refund streams.
Arms: Heavy Handed — melee final blows spawn an Orb and restore melee energy, another feed into the loop.
Chest: Solar / elemental resist mods for the price of standing in the pack you're farming.
Class item: Outreach or Bomber — faster Gambler's Dodge means more frequent stack refreshes.
Surge: Solar Weapon Surge ×3 (boots) to buff the Incandescent primary and Rocket.
Anti-Champion: sourced from the artifact — Revitalizing Blast (ignite → Unstoppable) and Anti-Champion Nosecone (Rocket → Barrier/heavies).
Artifact — Queensfoil Censer
The Solar artifact — it amplifies the build's whole Radiant→Scorch→Ignition spine and hands you the champion coverage the knife loop lacks on its own. Every pick feeds the verb economy: become Radiant, turn Radiant into Scorch, turn Scorch into ignitions.
Fever And Chill grants Radiant on rapid Solar weapon hits — a gun-driven Radiant source that arms Knock 'Em Down's full refund between knife throws.
Kindling Trigger makes Solar weapons apply Scorch while Radiant, so your Incandescent feeder seeds Scorch even when both knives are airborne.
Revitalizing Blast ignites a stunned Champion and clears your shield stun — Unstoppable coverage plus a free ignition into the pack.
Anti-Champion Nosecone makes Rocket Launchers hit Champions harder — the Barrier/heavy answer the knives can't solo.
Perpetual Destruction refunds Rocket ammo and reload on rapid final blows, keeping the heavy fed for the rooms Blade Barrage isn't up for.
Rays of Precision ignites on Solar precision final blows while Radiant, chaining your gun crits into the density the build feeds on.
Argent Ordnance spends Armor Charge for Rocket damage and reload, converting spare charge into burst when a Champion or boss needs deleting.
Where it shines
Add-dense PvE — patrols, Vanguard Ops, Battlegrounds, the clear phases of dungeons and Nightfalls, where grouped adds turn each throw into chained kills and rising stacks.
Sustained fights over burst rooms — anything that keeps enemies flowing rewards the ramp; the build peaks late, not on the opening throw.
Solo and low-team content — self-sufficient melee economy plus On Your Mark's ten-stack cure means it holds up without a support behind it.
Champion coverage: breaks Unstoppable intrinsically via ignitions (Revitalizing Blast on stun, plus scorch/ignition uptime). Bring the artifact Rocket with Anti-Champion Nosecone for Barrier/heavy Champions, and lean on a Lightweight/Rapid-Fire weapon archetype's intrinsic stun for Overload.
