MIDA's whole identity is one line of perk text: this weapon boosts movement speed. It's the only gun in the game that makes you faster just by being equipped. So we don't fight that — we stack it. Arcstrider for sprint-into-Arc verbs, St0mp-EE5 to weaponise the speed into airborne lethality and skating, Marksman's Dodge to keep the 16-round mag topped between kills. You never stop moving, the radar never blinks, and every Rapid-Fire scout headshot stuns an Overload from across the room.

The weapon

Intrinsic — MIDA Multi-Tool: "This weapon boosts movement speed. Radar stays active while aiming down sights."

Catalyst — Vital Intel: "Gain enhanced radar resolution and increased reload speed when combatants are in close proximity."

A 200-RPM Kinetic scout with sky-high handling (80), reload (80) and aim assist (100). The intrinsic is the build: a passive move-speed buff while held, plus radar that never goes dark when you ADS — so you can hold long sightlines and still see flanks. The catalyst adds enhanced radar resolution (you see blips inside a single blip — exact enemy count/position) and a reload boost when things get close, which on a fast-cycling scout means it never feels like you're out of ammo. It is a precision-killing add-clear and champion-tagging primary, not a DPS gun. Rapid-Fire 200-RPM frame → intrinsic Overload stun under Anti-Champion 2.0.

Loadout

Slot	Pick	Why
Subclass	Arcstrider (Arc)	Sprint-and-slide kit that matches a move-speed gun; Arc verbs feed off the constant motion.
Super	Gathering Storm (or Storm's Edge)	Stick the staff, jolt a whole room; Storm's Edge if you want a mobile teleport-Super to match the theme.
Class ability	Marksman's Dodge	Full reload on demand — keeps MIDA's 16-round mag fed without breaking the run.
Melee	Combination Blow (or charged Tempest melee)	Each Knockout-adjacent kill chains; dodge → melee resets via Lethal Current.
Grenade	Flux / Arcbolt Grenade	Jolt fuel for Flow State amplified uptime.
Aspect 1	Tempest Strike	Slide-melee ground uppercut that jolts — fires from the sprint/slide you're already doing.
Aspect 2	Flow State	Defeating a jolted target makes you Amplified → faster, better-handling, dodge regen.

Fragments

Spark of Momentum slide over ammo → reload + Bolt Charge — you're constantly sliding
Spark of Ions jolted kills → Ionic Trace
Spark of Discharge Arc kills → Ionic Trace
Spark of Resistance (DR when surrounded, +10 Melee). Swap in Spark of Haste (greatly increased Health stat while sprinting) for survivability — this build sprints permanently
so it's almost always live

Exotic armour — St0mp-EE5 (Legs): "Hydraulic Boosters: Increases slide distance and improves High Jump, Strafe Jump, and Triple Jump. Take less damage from targets when airborne."

Other two weapon slots:

Energy: an Arc weapon (SMG/Sidearm/Pulse) to drive Spark of Discharge/Ions Ionic Traces and Flow State jolts — the close-range partner MIDA isn't. (A literal MIDA Mini-Tool no longer carries a paired bonus in current sandbox — see Verify notes — so pick the best-rolled Arc primary you own.)
Heavy: a Machine Gun or Rocket for the boss/blocker damage MIDA can't provide. Match its element to an Arc surge if you stay all-Arc on energy.

Why this works (the mechanics)

The move-speed buff is unique and permanent. No other primary boosts run speed just by being held. St0mp-EE5 then converts that speed into distance: longer slides (more Spark of Momentum procs), higher/farther jumps, and airborne damage resistance. MIDA + Stompees is the original "Hunter skating" pairing for a reason — the gun and the legs multiply the same stat.
Radar never lies, so you can play long. A scout wants distance; ADS-ing a scout normally kills your radar. MIDA keeps it live, and the catalyst's enhanced resolution shows individual enemy positions inside a blip. You hold a sightline, headshot-chaining, and still know exactly when to dodge a flank.
Rapid-Fire frame = intrinsic Overload (Anti-Champion 2.0). Champion stun now rides the weapon archetype: Lightweight/Rapid-Fire → Overload. MIDA is a 200-RPM Rapid-Fire scout, so sustained fire stuns Overloads for free — no artifact mod, no exotic gimmick. That's your one guaranteed champion type from the primary; cover Barrier/Unstoppable on the other slots or via artifact.
Arc verbs pay you for the motion you're already doing. Tempest Strike fires out of a slide (which you do constantly); it jolts. Flow State turns any jolted kill into Amplified — more speed, more handling, faster dodge. Spark of Momentum reloads + grants Bolt Charge every time you slide over a brick. The subclass loop and the gun's identity are the same input: keep moving.
Marksman's Dodge is the reload that doesn't stop the run. 16 rounds cycles fast on a 200-RPM scout; instead of standing still to reload, you dodge (full reload) mid-traversal, which also feeds Lethal Current/Combination Blow resets. Reloading is a movement option here, not a pause.
Amplified + Spark of Haste + airborne DR is the survivability. Flow State keeps Amplified up (≈DR + faster everything); Spark of Haste hands you a big Health-stat bump while sprinting (always, for this build); Stompees adds airborne damage reduction on every jump. Three layers, all gated on "are you moving fast" — which you always are.

Stats & mods

Weapons 100+ → Class → Health. Weapons for primary damage vs minors/majors; Class high to keep Marksman's Dodge online as the reload engine; Health rides up off Spark of Haste while sprinting so it can be a softer priority.

Mods: Scout Rifle Loader + Scout Rifle Scavenger (keep MIDA fed), Kinetic Weapon Surge ×2–3 on legs (MIDA is Kinetic — direct damage), Dynamo (Super on dodge — you dodge constantly) and Powerful Attraction (vacuum Ionic Traces/orbs on dodge). One of each elemental resistance on chest; Orbs of Restoration to convert the orb flood (Spark of Amplitude if slotted) into ability energy.

Where it shines

Patrol / seasonal / mid-tier add-clear: the fantasy lives here — sprinting through a zone, headshotting reds at range, radar-aware, never reloading on the spot. Effortless, high-uptime, low-stress.
GM / Master (champions): MIDA's Rapid-Fire frame stuns Overload intrinsically — a reliable, ammo-cheap primary answer to the one champion type that's usually annoying to cover. Pair a Barrier/Unstoppable source on your other weapons or the artifact.
PvP / Crucible: the move-speed + persistent ADS radar is a genuine duelling edge — you reposition faster than your opponent and see them coming. Long a Crucible staple; the build's mobility identity carries straight over.
Champion coverage summary: Overload = covered (intrinsic, Rapid-Fire archetype). Barrier/Unstoppable = NOT from MIDA — assign to the Heavy/Energy slot or artifact mods.

Verify notes

Manifest-confirmed: MIDA Multi-Tool is a Kinetic Scout Rifle, 200 RPM / Impact 60 (hash 1331482397) — that's the Rapid-Fire archetype, which maps to Overload under Anti-Champion 2.0. Intrinsic perk text and catalyst (Vital Intel) quoted verbatim from `docs/encyclopedia/exotics.md` and `catalysts.md`.
St0mp-EE5 text verbatim from `docs/encyclopedia/exotics.md` (Leg Armor). All aspects (Tempest Strike, Flow State) and fragments (Spark of Momentum, Ions, Discharge, Resistance, Haste) verified verbatim against `docs/encyclopedia/aspects.md` and `fragments.md`.
MIDA Mini-Tool pairing: the legacy "equip both for a bonus" interaction is not present in the manifest (MIDA Mini-Tool is a legendary SMG, not in the exotics encyclopedia, and no paired-bonus perk surfaced). Treated as gone in current sandbox — the energy slot is "best Arc primary," not a forced Mini-Tool.
Super choice: Arcstrider's Super pool (Gathering Storm / Storm's Edge) is from `docs/knowledge/subclasses_and_aspects.md`; pick by taste — Gathering Storm for room-jolt, Storm's Edge for a teleport Super that matches the mobility theme. Not load-bearing to the gun loop.
Exact MIDA move-speed % and St0mp-EE5's airborne-DR value are not numerically stated in the encyclopedia (perk text is qualitative) — design is built on the stated behaviour, not invented numbers. Confirm magnitudes in-game.
Amplified's exact DR and Flow State's amplified-from-jolt timing: encyclopedia gives behaviour, not every number — verify in-game.
