One bow that does two debuffs at once. A perfectly-drawn shot is a poison arrow that stuns Overload and spreads to the pack; layer Volatile Rounds on top and the same arrow also detonates Void on hit. Gyrfalcon's hands you the Volatile every time you leave invis, and Stylish Executioner hands invis right back for every debuffed kill. You shoot, the room rots, you vanish, repeat.
The weapon
Poison Arrows (intrinsic, verbatim): "Arrows fired while perfectly drawn become poison arrows. Precision hits with poison arrows stun the combatant and spread poison to nearby ones. Strong against [Disruption] Overload Champions."
Le Monarque Catalyst — Unrelenting (verbatim): "Rapidly defeating targets triggers health regeneration. Guardians and powerful combatants count as more than one kill."
A Void Primary bow. Hold to perfect draw (the brief window at full draw) and the arrow becomes poisonous: precision hit stuns the target and spreads a ticking poison DoT to everyone nearby — that's a primary-ammo intrinsic Overload stun with no archetype dependency and built-in add-clear. The catalyst turns kill streaks into self-healing, so it sustains itself without a heal grenade. The poison DoT is damage you didn't pay ammo for, and it stacks on top of any debuff you layer underneath.

Slot
Pick
Why
Subclass
Nightstalker (Void)
Volatile + invis + weaken — three layers the bow rides on.
Super
Shadowshot: Deadfall
35% weaken tether groups the pack so one poison arrow spreads to all of them.
Class ability
Gambler's Dodge
Refills melee near enemies; with Vanishing Step it's also the invis button.
Movement
Triple Jump
Air control to hold perfect-draw while repositioning.
Melee
Snare Bomb (Vanishing)
Smoke debuff + weaken-on-detonate; an extra debuff source for Stylish/poison spread.
Grenade
Vortex Grenade
Lingering Void AoE; with Undermining it weakens a whole choke for the spread shot.
Aspect 1
Stylish Executioner
Any elemental-debuffed kill → invisibility + Truesight. Poison and Volatile both count — invis is free.
Aspect 2
Vanishing Step
Dodging makes you invisible — the deliberate invis trigger that arms Gyrfalcon on demand.

See Me, Feel Me (verbatim): "Your Void weapons gain Volatile Rounds after you emerge from being invisible. When you are invisible and defeat a combatant while using a finisher, all of your weapons gain bonus damage; you and your nearby allies gain a reserve overshield and improved class ability regeneration. These reserve overshields can be deployed by using a class ability."
This is the Le Monarque pairing. Le Monarque is a Void weapon, so every time you leave invis it gets Volatile Rounds — and you leave invis constantly (Stylish off any debuffed kill, Vanishing Step off any dodge). Now a single perfectly-drawn arrow carries two independent payloads: the poison DoT (stun + spread) and a Volatile detonation that explodes the target and chains Void damage to neighbours. The finisher clause hands the whole team an overshield + damage buff whenever you want to cash one in.
Why this works (the mechanics)
One arrow, two debuffs. Poison is the weapon's intrinsic; Volatile is Gyrfalcon's. They live on the same shot. The poison stuns Overload and spreads; the Volatile detonation explodes and chains. You get an Overload stun and AoE Void burst from a single primary-ammo bolt.
The invis loop is self-sustaining, so Volatile is always up. Stylish Executioner grants invis on any elemental-debuffed kill — and your own poison/Volatile arrows manufacture those debuffs. Kill a debuffed target → invis → emerge → Volatile Rounds re-applied → next arrow makes new debuffs → kill → invis. Gyrfalcon never goes quiet.
Weaken is the spread-multiplier. Echo of Undermining (Vortex) and Deadfall group-and-weaken the pack; one perfect-draw precision hit then sprays poison across weakened targets. Weaken is a debuff-bucket multiplier, so it boosts the poison ticks and the Volatile detonation and every fireteam weapon.
Champion coverage is intrinsic and ammo-free. Poison precision hits stun Overload — that's a Primary-ammo Overload answer with no special/heavy tax, freeing both other slots for Barrier/Unstoppable frames.
It heals itself two ways. The catalyst's Unrelenting triggers health regen on rapid kills (and poison spread makes rapid kills trivial), while Echo of Starvation gives Devour off the Breaches/Orbs that Echo of Harvest spawns from weakened kills. No heal grenade needed.
Truesight + invis is the survivability floor. Stylish gives both on every loop; Gyrfalcon's finisher clause adds a deployable reserve overshield on top.
Stats & mods
Weapons 200 → Health 100+ → Class. Weapons stat boosts PvE bow damage and the poison ticks; Class feeds Gambler's/Vanishing Step (the invis engine); Health for survivability under invis/Devour. Archetypes: Weapons/Class-favoured pieces.
Mods, by piece:
Helmet: Harmonic Siphon (Void kills → Orbs, feeds Harvest/Starvation) · Heavy/Special Ammo Finder for your other slots.
Chest: Arc/Solar/Void Resistance under the overshield layer.
Boots:Void Weapon Surge ×2 (≈+17% onto Le Monarque) · Bow Scavenger / Orbs of Restoration.
Class item: Powerful Attraction (dodge vacuums orbs) · Reaper · Class Font.
Where it shines
Endgame add-density (GMs, Master Lost Sectors, Nightfalls): poison spread + Volatile chains turn a perfect-draw shot into AoE clear; invis keeps you alive in −30/−40 content.
Champion coverage:Overload is handled intrinsically and for free off poison precision hits. Barrier/Unstoppable are NOT covered by this bow — pick the other two slots for them (see Weapons, below).
Boss/major DPS: not the lane — Le Monarque is a clear/control tool; poison is chip damage. Bring a heavy for damage phases.
Weapons (the other two slots)
Special: an Overload bow's job is done, so use Special for the champion gap — a Precision/Adaptive frame (Barrier) or Aggressive/High-Impact (Unstoppable). A Void Special (e.g. Void shotgun/GL) also keeps Gyrfalcon's Volatile relevant on a second gun.
Heavy: boss/major DPS — Machine Gun, Rocket, or LFR. Pick the champion frame Le Monarque + your Special don't already cover.
