Devil's Ruin — Sprite Fire (Hunter)
Weapon: Devil's Ruin (Sidearm · Primary/Kinetic ammo · Solar) · Subclass: Gunslinger · Role: Unstoppable-stunning Solar primary + Firesprite/ignition engine Sandbox: 9.7.0 · Created 2026-06-16
A primary Sidearm that holds the trigger into a Solar laser beam, stuns Unstoppables on its own, and litters the floor with Firesprites every kill. Solar Gunslinger is built to eat Firesprites for ability energy and to turn the beam's burn into full ignitions — so the gun feeds the subclass and the subclass feeds the gun. The catalyst then pays you a stacking damage buff for every Firesprite you scoop. Hold the beam, vacuum the sprites, melt the room.
The weapon
Close the Gap (exotic intrinsic, verbatim):
Final blows create Firesprites. After picking up a Firesprite, [Alternate Weapon Action] to enable a high-powered Solar laser beam mode. Strong against [Stagger] Unstoppable Champions.
Devil's Ruin Catalyst — Collective Action (verbatim):
Collecting an Elemental pickup or destroying a Tangle grants this weapon a stacking period of increased damage. Throwing a Tangle provides additional time.
>
Elemental pickups include [Solar]Firesprites, [Void]Void Breaches, [Arc]Ionic Traces, [Stasis]Stasis Shards, and [Strand]Strand Tangles.
What it does: tap-fire is a fast Solar Sidearm; hold the trigger (after grabbing a Firesprite) and it becomes a continuous high-powered laser that scorches and stuns Unstoppables. Because its own kills make Firesprites, the beam is self-sustaining: kill → sprite → grab → beam → kill. The catalyst closes the loop into damage — every Firesprite you collect is a stacking damage buff on the gun itself, and since this build manufactures Firesprites from three sources, that buff stays lit.
Loadout
| Slot | Pick | Why |
|---|---|---|
| Subclass | Solar — Gunslinger | The only subclass whose economy is built on Firesprites, scorch, and ignitions — exactly what Devil's Ruin produces. |
| Super |  Golden Gun: Marksman (or Blade Barrage) | Stays on-theme; Knock 'Em Down enhances both. Swap to Blade Barrage if you'd rather feed Shards/Galanor. |
| Class ability |  Marksman's Dodge | Reload-on-dodge for instant beam topoff; pairs with On Your Mark's class-ability trigger. |
| Melee |  Knife Trick (or Proximity Knife) | Scorch source → Ember of Searing melee-energy + Firesprite loop; Caliban's wants a knife that ignites. |
| Grenade | Tripmine (or Healing) | Tripmine ignites for Blistering grenade refunds; Healing if you want pure sustain. |
| Aspect 1 |  Gunpowder Gamble | Defeating targets charges a Solar explosive that ignites — every Devil's Ruin kill feeds the charge, and the ignition makes a Firesprite + spreads scorch. |
| Aspect 2 |  On Your Mark | Class ability / precision hits → reload + Weapons stat ×10. The beam is sustained precision damage, so it stacks this passively while it burns. |
Fragments (4):
Ember of Searing — defeating scorched targets grants melee energy and creates a Firesprite (+10 Class). The beam scorches → kills → free sprite + melee. Primary sprite engine.
Ember of Combustion — Solar Super final blows ignite + create a Firesprite (+10 Melee). Ties the Super back into the Firesprite economy.
Ember of Blistering — Solar-ignition kills grant grenade energy. Caliban ignites + Gunpowder Gamble ignites → grenade comes back fast.
Ember of Torches — powered melee → you and allies 
Radiant (-10 Grenade). Knife the first target → Radiant 25% damage on the beam. (Swap to 
Ember of Solace for longer Radiant/Resto if you run Knock 'Em Down.)
Exotic armour: 
Caliban's Hand (Gauntlets) — Roast 'Em: Your Proximity Knife scorches targets it damages with its explosions, or ignites targets on final blow. Turns the melee into a guaranteed ignition primer that stacks with the beam's scorch for fast ignitions → Blistering grenade + Searing Firesprites.
Other two weapon slots:
- Special: a Solar Special — Ember of Searing/Combustion don't care which gun scorches, but a Solar weapon keeps surge mods and Radiant value high. A Heal Clip / Incandescent shotgun or a Fusion both work; Incandescent spreads scorch to feed Searing while Devil's Ruin reloads.
- Heavy: Machine Gun or Rocket for the targets the beam can't chew — Devil's Ruin is a primary, so the Heavy is your true boss-DPS slot.
Why this works (the mechanics)
- The Firesprite loop is fully self-contained. Devil's Ruin kills make Firesprites (intrinsic). You need a Firesprite to enable the beam, so the gun bootstraps its own special mode. Ember of Searing then makes a second Firesprite every time a scorched target dies — and the beam scorches constantly — so you're never short of sprites for the beam or the catalyst.
- The catalyst turns sprite-vacuuming into a damage buff on the gun. Collective Action stacks increased damage every time you collect a Firesprite (an Elemental pickup). This build makes Firesprites from the gun, from Searing, from Combustion, and from Gunpowder Gamble ignitions — so the buff is effectively permanent uptime, paid for by playing normally.
- It's your Unstoppable answer with no mod slot spent. The beam carries an intrinsic [Stagger] Unstoppable stun (Anti-Champion 2.0 bespoke exotic stun). No Unstoppable artifact mod needed — that frees the artifact for surge and economy mods, and your Special/Heavy archetypes cover Barrier/Overload.
- Caliban + the beam = a two-source ignition engine. Knife ignites (Caliban), beam scorches → the scorch stacks tip into ignitions, and Gunpowder Gamble's thrown explosive ignites a whole pack. Every ignition: spreads scorch (more Searing sprites), refunds grenade (Blistering), and Gunpowder re-charges off the kills.
- On Your Mark double-dips the beam. Sustained beam = sustained precision hits = On Your Mark stacks → up to ×10 Weapons stat (9.7.0 PvE damage vs minors/majors) layered on top of the Collective Action stacks. Two independent multipliers, both fueled by just holding the trigger.
- Radiant rides for free. One knife (Ember of Torches) = Radiant on the beam; Caliban's scorch keeps scorched targets dying into Searing. The opener (knife → Radiant → beam) is the only piece of "rotation," and everything after self-sustains.
Stats & mods
Weapons 200 → Class 100+ → Health. Weapons maxes the beam's PvE damage and compounds On Your Mark; Class feeds Marksman's Dodge (the reload/On-Your-Mark trigger) and Singeing-style regen off scorch. Archetype-wise, target Weapons/Class-favouring pieces (Gunner/Specialist-leaning).
Mods, by intent:
- Boots: Solar Weapon Surge ×2 (≈+17% Solar weapon damage straight onto the beam) · Solar Scavenger / Sidearm Scavenger to keep reserves up — the beam drains the mag fast.
- Gauntlets:
Sidearm Loader (snappier reloads between bursts) · 
Melee Font if you want Caliban's knife back faster. - Helmet: Heavy Ammo Finder / Harmonic Siphon for orb generation off Solar multikills (feeds Super, which feeds Combustion).
- Class item:
Powerful Attraction (dodge vacuums Firesprites + orbs in one button — directly arms the beam and the catalyst stacks) · Class Font. - Stat tuning: +Weapons/−Health where available; the build leans on Radiant, Cure/Resto (Torches/Solace), and Caliban survivability, so Health is the cheapest dump.
Where it shines
- Add-dense PvE (GMs, Legend/Master, Onslaught, Nightfalls): the beam clears packs, every kill litters Firesprites, and the catalyst stays stacked. This is its home.
- Champion coverage: Unstoppable is handled by the weapon itself (intrinsic Stagger stun on the beam) — point the laser, hold, stun. Barrier and Overload are covered by your chosen Special/Heavy archetypes (Precision/Adaptive → Barrier; Lightweight/Rapid-Fire → Overload). Verify the exact archetypes you slot.
- Boss/miniboss DPS: Devil's Ruin is a primary, so it is not your boss burst — the beam tickles a boss while you build catalyst stacks, then your Heavy does the lifting. Treat the gun as champion-control + ad-clear + ability battery, not a damage-phase weapon.
- PvP: the beam is a strong duelling tool but ammo-hungry; this doc is a PvE build.
