Overcharge — Lucky Raspberry + Riskrunner (Arc Hunter)
Anchor: Lucky Raspberry · Subclass: Arcstrider (Arc) · Role: Chain-lightning ad-clear — Riskrunner overcharges into chaining bolts while Lucky Raspberry's jolting Arcbolt refunds itself, blanketing the room in Arc damage with built-in Arc DR Sandbox: 9.7.0 · Created 2026-06-24
Riskrunner wakes up when Arc damage hits it — and an Arc room is full of Arc damage. Once it's overcharged it chains lightning between enemies and shrugs off the Arc that fed it. Lucky Raspberry's Arcbolt jolts and chains too, and every jolt refunds the grenade. So the SMG keeps the room arced, the room keeps the SMG overcharged, the jolts keep the grenade coming, and you stand in a permanent lightning storm taking reduced Arc damage. Self-feeding chaos.
The pairing — why two exotics, not one
Lucky Raspberry is the chest, Riskrunner the Primary — both Arc, both about chaining lightning and staying overcharged:
Lucky Raspberry supercharges the 
Arcbolt Grenade: it chains to more targets, jolts what it hits, and damaging jolted targets (or applying jolt) refunds Arcbolt energy. It wants a constant source of jolt/Arc damage to keep the grenade cycling.
Riskrunner is a perpetual Arc-damage generator: 
Arc Conductor triggers when it takes Arc damage, making it chain lightning, resist Arc, and stay overcharged — and kills extend it. In any Arc fight (your own jolts/chains included) it's permanently on.- They meet on Arc damage + jolt: Riskrunner's chains + the jolted pack keep Arc Conductor lit, the jolt refunds Arcbolt (Lucky Raspberry), Arcbolt jolts more → more Arc damage → Riskrunner stays overcharged. The two exotics keep each other running with no outside input.
Loadout
| Slot | Pick | Why |
|---|---|---|
| Super |  Gathering Storm | Throw-and-embed staff jolts a wide area → jolt kills refund Arcbolt + feed Flow State, and it's the boss/heavy burst the kit lacks. |
| Class ability |  Gambler's Dodge | Arms Ascension's jolt and refunds Combination Blow; repositions inside the storm. |
| Melee |  Combination Blow | Neutral-game sustain (heal + dodge refund) between bursts. |
| Grenade | Arcbolt Grenade | Mandatory — the Lucky Raspberry engine; chains + jolts, and the jolt refunds it. |
| Aspect 1 |  Ascension | Spin-dodge jolts nearby targets (a ranged jolt source) and Amplifies allies → directly refunds Arcbolt (Lucky Raspberry) and feeds Flow State. 2 fragment slots. |
| Aspect 2 |  Flow State | Jolted kills → Amplified → faster reload (Riskrunner) + dodge regen + faster everything. 2 fragment slots. |
Spark of Discharge Arc weapon final blows → Ionic Trace — Riskrunner mows packs into traces
Spark of Ions jolted kills → Ionic Trace
Spark of Resistance DR while surrounded — you fight inside the storm
Spark of Recharge while critically wounded, melee + grenade regen faster — a comeback valve when the storm gets hairy
Exotic armour — Lucky Raspberry (Chest Armor)
Probability Matrix: Arcbolt Grenades have increased chaining capabilities and jolt targets hit. Damaging combatants with jolt or applying jolt to targets grants additional Arcbolt Grenade energy.
It turns the Arcbolt into a self-funding jolt-chain: it hits more targets, jolts them, and every jolt feeds the grenade back. In an Arc build that's constantly jolting (Riskrunner chains, Ascension, Gathering Storm), the Arcbolt is almost always ready.
Exotic weapon — Riskrunner (Submachine Gun · Arc · Primary)
Arc Conductor: "When taking Arc Damage, this weapon becomes more powerful and resists incoming Arc Damage. Kills extend the time in this overcharged state."
A 900-RPM Arc SMG that thrives in Arc chaos: any Arc damage flips it into Arc Conductor — overcharged, chaining lightning between enemies, and resistant to the Arc damage that triggered it. Kills keep it lit, so in a jolt-soaked room it never turns off. It's the engine that keeps the lightning storm fed.
Why this works (the mechanics)
- The overcharge is self-sustaining here. Riskrunner needs Arc damage; your Arcbolt jolts, Riskrunner's own chains, Ascension, and Gathering Storm flood the room with it — so Arc Conductor stays on permanently, chaining lightning and tanking Arc damage.
- The grenade pays for itself. Lucky Raspberry refunds Arcbolt energy off every jolt; the room is always jolted, so the chaining Arcbolt is up constantly → more jolt → more refund.
- Jolt drives the subclass loop. Jolted kills → Ionic Traces (Spark of Ions / Discharge) → ability energy → Amplified (Flow State) → faster reload on the 900-RPM SMG → more chains → more jolt.
- You're hard to hurt with Arc. Arc Conductor resists Arc damage, Spark of Resistance adds DR while surrounded, Amplified adds more — and you're meant to be in the middle of the pack.
- Champions covered. Jolt handles Overload (Arcbolt + Ascension + Gathering Storm + chains); Barrier + Unstoppable — archetype frames on the Special/Heavy.
Weapons
- Riskrunner (Arc Primary SMG) — the chain-lightning engine; keeps Arc Conductor lit.
- Special/Heavy: an Arc option keeps surges + Spark of Discharge traces live; a boss-DPS Heavy for the targets chains can't chew.
- Champions (Anti-Champion 2.0): Overload — jolt (everywhere); Barrier + Unstoppable — archetype frames on Special/Heavy.
Stats & archetypes
Priority: Weapons 150 → Grenade 100 → Health 100 → Super/Class/Melee dump.
- Weapons 150 — Riskrunner throughput (it's your whole neutral game); the first 100's PvE damage bonus.
- Grenade 100 — Arcbolt uptime is the second engine; Lucky Raspberry's refund plus the stat keep it nearly constant.
- Health 100 — survivability floor on top of Arc Conductor's Arc-resist + Spark of Resistance.
Archetypes: 
Gunner / Powerhouse (Weapons),

Grenade Font, Arc Weapon Surge ×2, Arc/Harmonic Siphon, 
Bomber on the class item.
Artifact — Encrypted Data Disk (Renegades)
Picks (2/3/2): 
Fierce Proxemics + 
Press the Advantage — 
Dielectric + 
Blinding Jolts + 
Counter Energy — 
Elemental Orbs: Arc + 
Tazer Tag The Arc/jolt artifact — it converts the jolt flood into Bolt Charge, blind, and Orbs:
- Dielectric — defeating Arc-debuffed (jolted) targets → Bolt Charge; rapid ones → Orb + heal. The room is permanently jolted, so this never stops.
- Blinding Jolts — final blows on jolted combatants blind nearby ones — free CC layered onto every chain kill.
- Elemental Orbs: Arc — Arc final blows spawn an Arc orb you shoot for a jolting explosion — more AoE jolt + Orb economy.
- Tazer Tag — Arc melee hits jolt + ramp damage (for the Combination Blow filler).
- Fierce Proxemics / Counter Energy — finisher → ability energy / champion-stun → least-charged ability: keeps Gathering Storm + the Arcbolt topped.
- Press the Advantage — shield break → handling/reload/stability for the SMG.

The loop
- Open with Arcbolt (jolts + chains, Lucky Raspberry) → spray Riskrunner → the Arc damage flips Arc Conductor → it chains lightning through the pack.
- Jolt everywhere → Arcbolt refunds (Lucky Raspberry) → Ionic Traces + Amplified (Flow State) → faster reload → more chains. Ascension on dodge to jolt + Amplify.
- Jolt kills → Bolt Charge / Orbs / Blind (artifact) → more CC + economy; Arc Conductor stays lit off the constant Arc damage, and you tank Arc in return.
- Gathering Storm for a boss or a dense reset — a wide jolt that refuels the whole loop. Never stop the lightning.
