Sleight of Hand — Assassin's Cowl + Monte Carlo (Arc Hunter)
Anchor: Assassin's Cowl (Helmet) · Subclass: Arcstrider (Arc) · Role: Infinite invis-melee assassin — Monte Carlo is the melee battery that keeps Combination Blow firing for non-stop Cowl invis + heal Sandbox: 9.7.0 · Created 2026-06-24
Assassin's Cowl pays you invis + a heal for every powered-melee kill, and Combination Blow is that kill. The only thing that ever stalls the loop is the fist being on cooldown — so Monte Carlo becomes the battery: every bit of damage you deal refunds melee energy, and kills can fully recharge it outright. Spray to close the gap, punch to vanish. The fist never stops, so the invis never drops.
The pairing — why two exotics, not one
Assassin's Cowl is the 
helmet, Monte Carlo the Primary:
Assassin's Cowl turns a powered-melee final blow into invis + a heal (bigger + longer vs majors/champions). Its weakness is melee uptime — if a kill doesn't land or the fist is empty, the loop stalls.
Monte Carlo is a melee battery: "Dealing damage with this weapon reduces your melee cooldown and grants a chance to fully charge your melee ability with each kill." It refills the fist passively as you shoot.- They meet on melee energy: Monte Carlo gunfire tops the fist between punches and can hand you a full charge on a gun kill, so Combination Blow is always ready → Cowl always procs → invis + heal never lapse. The gun covers the ranges the fist can't and pays for the fist while doing it.
Loadout
| Slot | Pick | Why |
|---|---|---|
| Super |  Gathering Storm | Throw-and-embed staff jolts a wide area → jolted kills feed Flow State/Spark of Ions and seed the next melee chain. (Arc Staff to roam.) |
| Class ability |  Gambler's Dodge | Near enemies, refunds the melee — a second feed under Monte Carlo, and it arms Lethal Current. |
| Melee |  Combination Blow | The build. Chained final blows heal, refund the dodge, and stack ×3 damage — and each kill triggers Cowl's invis + heal. |
| Grenade | Flux / Arcbolt | Cheap Arc grenade for a jolt proc (with Spark of Shock); mostly a stat dump. |
| Aspect 1 |  Lethal Current | After dodging, the next melee jolts + drops an aftershock and blinds jolted targets — CC + jolt baked into the dodge you already throw. |
| Aspect 2 |  Flow State | Jolted kills → Amplified; while Amplified, faster dodge regen + greatly increased reload — reinforces the dodge↔melee rhythm. |
Spark of Resistance DR while surrounded, +10 Melee
Spark of Ions jolted kill → Ionic Trace → ability energy
Spark of Amplitude rapid kills while Amplified → Orbs
Spark of Frequency melee hits boost reload/stability; enhanced while Amplified
Exotic armour — Assassin's Cowl (Helmet)
Vanishing Execution: Powered melee final blows grant invisibility and restore a portion of health and shields. Finishers and final blows against more powerful targets increase the duration of the invisibility and the amount of health and shields restored.
The whole build hangs on powered melee final blows — Combination Blow's killing punch is one, so every link procs Cowl (invis + heal) for free. It gets safer as content gets harder: majors/champions extend the invis and grow the heal.
Exotic weapon — Monte Carlo (Auto Rifle · Kinetic · Primary)
Monte Carlo Method: "Dealing damage with this weapon reduces your melee cooldown and grants a chance to fully charge your melee ability with each kill."
A 600-RPM Kinetic AR. It isn't here for damage numbers — it's the melee battery. Sustained fire shaves the Combination Blow cooldown and gun kills can hand you a full melee, so even when a target is out of punch range (or a champion won't die to a fist), the fist is back the moment you need it.
Why this works (the mechanics)
- Monte Carlo removes the only stall. Cowl's loop breaks only when the melee is empty; Monte Carlo keeps it filled with gunfire + full-charge-on-kill. Now the chain survives bad luck, ranged targets, and champions you can't punch to death.
- One kill, three payouts. A Combination Blow final blow heals + cloaks (Cowl), heals again + stacks ×3 damage (Combination Blow), and refunds the dodge. Cowl and the melee heal share the trigger — double heal, free invis.
- Invis closes the gap safely. You vanish on the kill and walk/dodge to the next target off-radar; the dangerous part of melee — closing in — happens untargetable.
- Lethal Current weaponises the dodge. The dodge you throw (to refund the fist / stay Amplified) also makes the next melee jolt + blind + aftershock — free CC and chaining damage so one punch clears a cluster.
- Jolt → Amplified → faster everything (Flow State). Jolted kills → Amplified → faster dodge + reload (Monte Carlo reloads quicker too) → back into the rhythm; Spark of Frequency/Amplitude both upgrade while Amplified.
- Economy tops up for free. Spark of Ions (jolt kill → trace → ability energy) + Spark of Amplitude (amplified streak → Orbs) keep Gathering Storm and abilities fed just by running the loop.
Weapons
- Monte Carlo (Kinetic Primary) — the melee battery + your ranged option.
- Special/Heavy: cover the ranges the fist can't and act as a panic button before invis re-cloaks you; bring the champion frames the kit lacks.
- Champions (Anti-Champion 2.0): Jolt covers Overload (Lethal Current + Gathering Storm + Spark of Shock); Barrier + Unstoppable — weapon archetype frames on the Special/Heavy.
Stats & archetypes
Priority: Melee 200 → Health 150 → Class 100 → Weapons/Super dump.
- Melee 200 — the cooldown of the ability the build is; scales the Gambler's refund and bonus melee damage. Monte Carlo + Gambler's + Heavy Handed do the rest.
- Health 150 — you fight in melee range even with the heals.
- Class 100 — Gambler's/Flow State dodge uptime.
Archetypes: 
Brawler (Melee), Skirmisher (Melee/Weapons), 
Reaver (Class/Melee), 
Bulwark (Health). Mods: Melee Kickstart ×2, Recuperation / Better Already, 
Heavy Handed,

Picks (2/3/2): 
Dielectric + 
Photonic Flare — 
Flashover + 
Harsh Refraction + 
Gold From Lead — 
Defibrillating Blast + 
Elemental Supercharger The Arc-leaning artifact: it turns the Arc kill loop into Bolt Charge → Amplified and covers the Barrier/Unstoppable champs Jolt can't.
- Dielectric — Arc-debuffed kills → Bolt Charge; rapid kills → Orb + heal, feeding the loop.
- Photonic Flare — Arc kills on severed/exhausted release a blinding burst, layering CC onto Lethal Current's blind.
- Flashover — max Bolt Charge → Amplified, paying Bolt Charge straight into Flow State's Amplified state.
- Defibrillating Blast — champion stun → max Bolt Charge; the bolts jolt + heal — your Barrier/Unstoppable answer + a heal + jolt feed.
- Gold From Lead — special pickups → Heavy, sustaining the slot that covers what the fist can't reach.
- Harsh Refraction / Elemental Supercharger — theme/fill; see Verify notes.

The loop
- Open with a dodge (Lethal Current arms the punch) or spray Monte Carlo to close + top the fist.
- Combination Blow the jolted target → kill → Cowl cloaks + heals, Combination Blow heals + stacks + refunds dodge, the jolt kill → Amplified (Flow State) + a trace (Spark of Ions).
- Stay invisible, Monte Carlo any target out of reach (refilling the fist), punch the next → repeat. The gun guarantees the fist is never the bottleneck.
- Gathering Storm to reset a dense room; finish a champion/major for Cowl's longest invis + biggest heal.
