ARC Circuitry is a rare material that gates several practical upgrades in ARC Raiders, including Medium Shields and late‑game components. You’ll get it most reliably by looting ARC technology in the field—especially probes—and, once Refiner 3 is online, by converting ARC Alloy into Circuitry on demand.
ARC Circuitry quick facts and core uses
| What | Details |
|---|---|
| Primary sources. | Drops from destroyed ARC enemies and ARC activities; strong results from ARC probes. |
| Crafting source. | Refiner 3 converts 6× ARC Alloy → 1× ARC Circuitry. |
| Key recipes that consume it. | Medium Shield (Gear Bench 2): 4× Battery + 1× ARC Circuitry. Power Rod (Refiner 3): 2× Advanced Electrical Components + 2× ARC Circuitry. |
| Recycling value. | Recycling 1× ARC Circuitry yields 2× ARC Alloy (or 1× via salvage). |
| Progression note. | Refiner 3 upgrade requires 10× ARC Circuitry, so you’ll need field drops first before you can craft it. |
Method 1: Farm ARC probes (fastest, most consistent)
Step 1: Track probes by their audio and visual tells. Listen for a repetitive electronic ping and look for tall white ARC structures or conspicuous smoke plumes that are visible from far away.
Step 2: Close in with cover and breach the probe. Probes are loud and placed in open ground, so assume you’re audible and visible to nearby threats while interacting with them.
Step 3: Loot the probe immediately and reposition. Sweep the area once, collect any Circuitry and other ARC components, then rotate to a new landmark to avoid drawn‑out fights that slow your material intake.
Method 2: Clear ARC enemies and loot wreckages in active zones
Step 1: Enter zones with a high ARC presence. Patrols, mini‑boss routes, and ongoing ARC activities concentrate enemy spawns and their wreckages, which raises your odds of Circuitry drops.
Step 2: After engagements, loot every ARC body and wreck. Circuitry is a rare topside material tied to destroyed ARC units and the technology they leave behind.
Step 3: Run short, repeatable loops and extract regularly. Banking small hauls consistently outpaces long, risky routes—especially while you’re stockpiling the 10 pieces needed for Refiner 3.
Method 3: Craft ARC Circuitry at Refiner 3 (sustainable supply)
Step 1: Upgrade your Refiner to Level 3. You’ll need 3× Motor, 6× Bombardier Cell, and 10× ARC Circuitry to complete this tier, so plan a few dedicated field runs before you rely on crafting.
Step 2: Convert ARC Alloy into Circuitry. At Refiner 3, use 6× ARC Alloy to craft 1× ARC Circuitry. This turns the frequent Alloy drops from ARC enemies into a steady Circuitry pipeline.
Step 3: Reserve crafted Circuitry for high‑impact builds. Prioritize Medium Shields and Power Rods, and avoid recycling crafted Circuitry back into Alloy unless you’re correcting a temporary material shortfall.
Recipes that need ARC Circuitry (and where to make them)
| Item | Station | Recipe |
|---|---|---|
| ARC Circuitry (crafting). | Refiner 3. | 6× ARC Alloy → 1× ARC Circuitry. |
| Medium Shield. | Gear Bench 2. | 4× Battery + 1× ARC Circuitry. |
| Power Rod. | Refiner 3. | 2× Advanced Electrical Components + 2× ARC Circuitry. |
| Recycle (material return). | Recycle/Salvage. | 1× ARC Circuitry → 2× ARC Alloy (recycle) or 1× ARC Alloy (salvage). |
Extraction and inventory discipline (to keep what you farm)
Step 1: Bank early when carrying multiple rare drops. Circuitry stack sizes are limited, so frequent extractions prevent a single wipe from erasing a productive loop.
Step 2: Separate “spend” vs. “stockpile” pieces. Keep a running tally for the 10 required by Refiner 3 and avoid dipping into that reserve so the upgrade stays on schedule.
Step 3: Convert only what you need. If ARC Alloy is your new bottleneck after Refiner 3, pause Circuitry crafting until you stabilize Alloy inflow from ARC enemies again.
Focus your early runs on probes and dense ARC patrols to hit the 10‑piece gate, then let Refiner 3 turn Alloy into a dependable Circuitry stream for the rest of your progression.
