Weapon: Trespasser (Sidearm · Primary · Arc) · Subclass: Arcstrider · Role: Close-range Arc add-clear engine — punch, reload, superburst, repeat Sandbox: 9.7.0 · Created 2026-06-16

Trespasser pays you for the one habit Combination Blow already demands: kill, then reload. Punch a target dead with the Arc melee, reload, and the next burst is a longer, harder superburst that overkills the next target — which feeds the next punch. The whole build is a single tight loop where the melee, the reload and the gun all reward the same beat. Arc Hunter is the iconic home: amplified for the reload speed, Liar's Handshake for the punch that does the killing, and an Arc Primary that never needs ammo to keep firing.

The weapon

Unrepentant (intrinsic): "Reloading after defeating a target causes the next burst to be a longer, more powerful superburst."

Trespasser Catalyst — Tunnel Vision: "Reloading after defeating a target greatly increases target acquisition and aim down sight speed for a short duration."

Trespasser is a 491-RPM burst-fire Arc Sidearm in the Primary (Kinetic) slot — infinite white ammo. The intrinsic is the entire pitch: get a kill with anything, reload, and the next trigger pull is a beefed-up superburst that hits harder and longer than a normal burst — enough to one-tap most red-bars and chunk an orange-bar. The catalyst stacks a snap-to-target + ADS-speed boost on the same reload, so the superburst lands instantly on the next head. The reward beat — kill → reload → superburst — is exactly the rhythm Combination Blow's melee loop already runs, so the gun and the subclass share one trigger.

Loadout

Slot	Pick	Why
Subclass	Arcstrider (Arc Hunter)	Combination Blow melee + amplified reload speed is the perfect Unrepentant partner.
Super	Gathering Storm	Anchored Arc Staff for a boss/champion; jolts a pack to seed Ionic Traces. (Arc Staff if you prefer roaming add-clear.)
Class ability	Gambler's Dodge	Refills melee energy near enemies (scaled by Class stat) — a free Combination Blow swing on demand.
Melee	Combination Blow	Kills grant ramping melee damage (×3), class-ability energy, and health — and are the kill that arms Unrepentant.
Grenade	Flux Grenade	Sticks + heavy single-target detonation for the orange-bar the superburst doesn't finish. (Arc Bolt for chains if you prefer.)
Aspect 1	Lethal Current	After dodging, next melee jolts + adds an aftershock and lunge range — turns one dodge-punch into a multi-kill, each arming a reload.
Aspect 2	Flow State	Defeating a jolted target makes you amplified → faster reload (feeds Unrepentant) + faster move/weapon ready + DR.

Fragments

Spark of Discharge Arc weapon final blows → Ionic Trace → Bolt Charge — Trespasser is an Arc gun, so every superburst kill feeds this
Spark of Ions jolted-target kills → Ionic Trace — Lethal Current jolts, so every punch loops energy back
Spark of Resistance DR while surrounded — this is a face-tank melee build; +10 Melee
Spark of Feedback taking melee damage boosts your melee damage; +10 Health

Exotic armour — Liar's Handshake (Gauntlets)

Cross Counter: "Using your Arc melee ability or being hit by a melee attack will allow you to follow up with an extremely powerful melee counterpunch that will heal you."

Liar's is the build's heart. Throw Combination Blow → Cross Counter immediately enables a massively-damaging healing counterpunch off the same input. That second punch is what actually kills the orange-bars, and each kill arms Unrepentant — so you reliably manufacture the "defeated a target" condition the gun needs, then reload into a superburst. The heal makes the close range survivable; Combination Blow's own health-on-kill stacks on top. One melee button = a kill + a heal + a loaded superburst.

Why this works (the mechanics)

Every system rewards the same beat: kill → reload. Unrepentant wants a kill then a reload. Combination Blow + Liar's Cross Counter provide the kill; the manual reload after it both arms the superburst (Unrepentant) and the snap-aim (Tunnel Vision). You're never choosing between "play the gun" and "play the melee" — they are one loop.
Liar's Handshake does the killing the gun can't reach. A 491-RPM Sidearm is a close-range weapon, and so is the whole subclass. Cross Counter's counterpunch deletes the orange-bar in melee range, heals you through the exposure, and hands the next superburst a fresh target.
Amplified is a reload-speed buff, and Unrepentant is a reload trigger. Flow State makes jolted-target kills amplify you; amplified gives faster reload + weapon ready. Faster reload means the kill→reload→superburst loop cycles quicker, and amplified DR keeps you alive in the punch range.
Jolt closes the energy loop. Lethal Current jolts on the dodge-punch; Spark of Ions turns jolted-target kills into Ionic Traces; Spark of Discharge does the same off any Arc weapon kill — and Trespasser is Arc, so superburst kills also make Traces. Traces refund melee/grenade energy and grant Bolt Charge, so the gun literally reloads your fists.
Infinite ammo, infinite loop. Trespasser sits in the Primary slot and never runs dry. The superburst is free white-ammo damage on tap, so the loop has no resource ceiling — the only cap is how fast you punch and reload.
Gambler's Dodge is the reset button. Out of melee energy or surrounded? Dodge near a target refunds Combination Blow (scaled by Class stat) and Lethal Current re-jolts the next swing — instantly restarting the chain.

Stats & mods

Melee 200 → Class 100+ → Health 100. Melee is the whole build (Combination Blow ramp + Cross Counter + Gambler's refund scaling); Class drives Combination Blow's energy-on-kill and dodge uptime; Health for the face-tank range. Weapons/Super are dump stats — the gun runs on its intrinsic, not the Weapons stat ramp.

Mods: Melee Font ×2 and Class Font toward the targets · Heavy Handed (melee kills → melee energy + reload, doubling down on the loop) · Special/Primary Ammo Finder is irrelevant (Trespasser is white-ammo) — instead run Reaper + Orbs of Restoration on the class item to convert the orb flood (Spark of Amplitude territory) back into ability energy. Surge: Arc Weapon Surge ×2 on boots (straight onto Trespasser and your Arc loadout). Resist mods to taste — Arc/Solar/Void Resistance on chest under the amplified DR.

Where it shines

Strikes / Nightfalls / GMs (add-dense): the natural habitat — endless red/orange-bars feed the punch-reload-superburst loop, and amplified + Cross Counter heals carry the survivability.
Onslaught / Battlegrounds / horde modes: infinite-ammo Primary + self-healing melee means you never leave the fight to chase bricks.
Champion coverage — flag this: Trespasser is an Adaptive/burst Sidearm with no bespoke anti-Champion intrinsic, so it does not stun champions on its own. Cover them with the loadout: Gathering Storm + jolt (Lethal Current / Spark of Shock-adjacent) handle Overload behaviour and stagger; bring a Heavy or your other slot in a stun archetype for Barrier/Unstoppable. The gun is the add-clear engine, not the champion answer.

Verify notes

Trespasser element/ammo/RPM confirmed from the manifest (`inspect_item.py 1234150730`): Damage Arc, Type Sidearm, 491 RPM, intrinsic Unrepentant. The encyclopedia entry (`exotics.md:343`) lists the perk text but not element/ammo — element/ammo are taken from the manifest item definition directly. Primary/Kinetic-slot placement is the long-standing classification for Trespasser; confirm slot in-game if it matters to your loadout.
Unrepentant and Tunnel Vision (catalyst) quoted verbatim from `exotics.md:343` and `catalysts.md:154`.
Combination Blow text from manifest (`inspect_item.py`): ramping melee damage ×3, class-ability energy + heal on kill, energy scaled by Class stat. Liar's Handshake / Cross Counter verbatim from `exotics.md:36`. Lethal Current (`aspects.md:108`) and Flow State (`aspects.md:72`) verbatim. Fragments verbatim from `fragments.md` (Discharge 72, Ions 82, Resistance 86, Feedback 75) including their stat deltas.
No bespoke champion stun on Trespasser — Anti-Champion 2.0 ties stuns to archetypes and this Sidearm carries none in its perk list, so champion duty is delegated to Super/jolt and the other weapon slots. Verify the exact burst archetype in-game if you want to claim an intrinsic stun.
Superburst exact damage/duration, Tunnel Vision's snap/ADS magnitudes, and amplified's reload-speed % are not in the encyclopedia (it records behaviour, not every number) — confirm in-game.
Knowledge-doc fallback: none needed; every armour piece, aspect and fragment was verified against `docs/encyclopedia/`.
