Arc Raiders Close Scrutiny Loot Guide: Assessor Matrix, Vaporizer Regulator & All New Items
The Close Scrutiny event doesn't just bring a brutal new challenge — it introduces three new blueprints, two brand new crafting materials critical to the current project, and a spread of high-value Arc components worth farming even if you never pull a legendary drop. This guide covers every piece of loot tied to the event: what drops, where it comes from, what it's worth, and how it feeds into the new project progression.
The Two New Crafting Materials You Need to Know About
Before getting into blueprints, it's worth covering the two new materials introduced alongside Close Scrutiny, because these are going to matter a lot for project progression and are worth picking up every single run regardless of what else you find.
Assessor Matrix
— Assessor Matrix —
The Assessor Matrix is the primary drop from the Arc Assessor compartments themselves. You will almost certainly be picking these up every time you successfully breach and loot an Assessor, even on runs where no blueprint drops.
Value: 5,000 credits each if sold back at Spiranza
More importantly, Assessor Matrices are a required crafting material for the current project — specifically the High Gain Antenna:
- Phase 2: Requires 6 Assessor Matrices
- Phase 3: Requires 18 Assessor Matrices
That's a significant grind. If you're working toward completing the High Gain Antenna project and pushing into the later phases, farming Close Scrutiny Assessors is your primary source for this material. Every run where you successfully loot even one compartment is a run that moves your project progress forward, even if no blueprints show up.
Vaporizer Regulator
— Vaporizer Regulator —
The Vaporizer Regulator drops from killing Vaporizers — the new aerial Arc unit introduced in this event. These are also tied to project progression:
- Phase 2: Requires 4 Vaporizer Regulators
- Phase 3: Requires 15 Vaporizer Regulators
Phase 3's requirement of 15 is a serious ask, particularly given how dangerous and resource-intensive Vaporizer kills are. If you're actively fighting Vaporizers during your Assessor runs rather than avoiding them entirely, banking the Regulators for project use is far more valuable than selling them.
General Arc Loot from This Event
Beyond the two dedicated materials above, the Close Scrutiny event drops a solid range of general Arc components that are either sellable for good value or usable in crafting. Confirmed drops from Assessor runs include:
- Arc Performance Steel
- Advanced Arc Power Cells
- Arc Flex Rubber
- Standard Arc components in varying quantities
All of these feed into the broader new project introduced with Flashpoint, so even runs where the RNG doesn't favour you with a blueprint or rare material are still productive from a crafting standpoint.
Combat Supply Caches: Don't Overlook These
One of the underreported features of Close Scrutiny is the Combat Supply Caches that appear marked on the map during the event. These are distinct from the Arc Assessors and represent entirely separate loot opportunities that many players run straight past.
Combat Supply Caches contain:
- Ammo Crates
- Medicine Bags
- Grenade Tubes
- Weapon Cases
The Weapon Cases in particular can contain high-value drops — blueprint finds, including rare weapon blueprints, have been confirmed from these caches. If you arrive at an Assessor and the Arc presence is too intense to breach safely, swinging past the Combat Supply Cache markers on your map is a worthwhile detour. They're often ignored by players laser-focused on the Assessors, meaning you may find them completely untouched.
New Blueprints from the Close Scrutiny Event
Three new blueprints were introduced alongside the Close Scrutiny event and Flashpoint update. Here's where each one comes from and what it does.
Dolabra — Legendary Energy Shotgun Blueprint
Source: Arc Assessors (Close Scrutiny event) Rarity: Extremely rare Type: Legendary Energy Shotgun
The Dolabra is the headline blueprint of this update and the most coveted drop in the Close Scrutiny event. It's a Legendary Energy Shotgun described as being built to punch through armour plating at close range — which given the current meta of energy weapons and shield-heavy PvP builds, is a very strong proposition on paper.
Be realistic about the drop rate going in: players have reported looting dozens of Assessors without seeing a single Dolabra blueprint. It is genuinely rare, not just uncommon. The Arc Assessors during Close Scrutiny are currently the primary and only confirmed source for this blueprint. If better sources are discovered, the community will likely surface them quickly, but for now, Assessor farming is your only avenue.
Given the difficulty of the event and the low drop rate, every run that gets you Assessor Matrices for project progression is still a productive run even if the Dolabra doesn't show. Treat it as a bonus when it appears rather than the sole metric for a successful run.
Canto — Medium Ammo SMG Blueprint
Source: Hurricane Caches (Hurricane event) — NOT the Close Scrutiny event Type: Medium Ammo SMG
The Canto is worth mentioning here because it was introduced at the same time as Close Scrutiny and players naturally assume both new weapon blueprints come from the same event. They don't.
The Canto SMG blueprint drops exclusively from Hurricane Caches during the Hurricane event, not from Arc Assessors. If you're hunting the Canto, you need to load into Hurricane Raid maps and loot the Hurricane-specific cache locations there. There is no confirmed Canto drop from the Close Scrutiny event.
Surge Coil — Deployable Electrification Device Blueprint
Source: Breachable containers, lockers, and standard containers — multiple maps and events Best Maps: Damn Battlegrounds (46% of community finds reported here) Best Event: Electromagnetic Storm (primary), though Close Scrutiny can also yield it Type: Equipment — Deployable device that periodically electrifies its surroundings
The Surge Coil is a deployable piece of equipment that emits periodic electric pulses around its placement point. Unlike the Dolabra and Canto, the Surge Coil is not locked to a single event or source — it can drop from breachable containers, lockers, and standard containers across multiple maps.
Community data via Metaforge currently shows:
- 46% of Surge Coil finds are reported on Damn Battlegrounds
- The Electromagnetic Storm event is the most commonly associated event for drops
- Close Scrutiny also has a chance to yield the Surge Coil from Assessor loot
If you're specifically farming for the Surge Coil blueprint, running the Research and Administration Building on Damn Battlegrounds during the Electromagnetic Storm is your highest-probability play based on current community data. That said, it can turn up in Close Scrutiny runs as well, so it's worth keeping an eye out during every Assessor loot.
Loot Priority: What to Focus On Per Run
Given everything available in this event, here's how to think about loot priority depending on where you are in your progression:
If you're pushing project completion (High Gain Antenna): Assessor Matrices are your primary objective. Dolabra is a bonus. Fight or avoid Vaporizers based on how many Regulators you still need for Phase 2 and 3. Don't skip Combat Supply Caches — Weapon Cases there can contain materials you need.
If you're hunting the Dolabra blueprint: Run every Close Scrutiny Assessor you can reach. Use the cloak-and-smoke strategy to maximise the number of compartments you successfully breach per run. Bank your Assessor Matrices as a consolation on dry runs — they'll be useful for the project and sell for decent value if you're capped.
If you're hunting the Surge Coil: Close Scrutiny gives you a chance at it, but Damn Battlegrounds during Electromagnetic Storm is a more reliable farm. Running Close Scrutiny for Surge Coil specifically isn't the optimal play compared to dedicated Damn Battlegrounds runs.
If you're a newer player building up resources: The general Arc components and Combat Supply Cache drops from this event are genuinely strong. Advanced Arc Power Cells, Arc Performance Steel, and Arc Flex Rubber all feed into meaningful crafting, and the 5,000-credit Assessor Matrices are solid sell value for building up funds.
Summary: Close Scrutiny Loot at a Glance

|---|---|---|
| Assessor Matrix | Arc Assessor compartments | High Gain Antenna project (6 for Phase 2, 18 for Phase 3) — or 5,000cr sell value |
| Vaporizer Regulator | Killing Vaporizers | High Gain Antenna project (4 for Phase 2, 15 for Phase 3) |
| Dolabra Blueprint | Arc Assessors | Legendary Energy Shotgun — craft and use |
| Canto Blueprint | Hurricane Caches (Hurricane event only) | Medium Ammo SMG — craft and use |
| Surge Coil Blueprint | Any breachable containers (best on Damn BG / Electromagnetic Storm) | Deployable electric area device |
| Arc Components (various) | Arc kills and Assessor loot | Crafting / sell |
| Combat Supply Cache items | Map-marked supply caches | Ammo, heals, grenades, weapon drops |
Final Thoughts
The Close Scrutiny event is dense with loot opportunity — but it rewards players who understand the full picture rather than just chasing the headline Dolabra drop. The Assessor Matrix grind for the High Gain Antenna project is real and ongoing, the Vaporizer Regulators add up faster than you'd expect once you start actively hunting Vaporizers, and the Combat Supply Caches are a genuinely underused source of free high-value gear.
Go in with the cloak, smoke your way through, grab what you can from each compartment, and treat every matrix you pull as progress even when the legendary doesn't drop. The Dolabra will come eventually — and when it does, you'll already be ahead on project materials.
