ARC Raiders: How to Get Canto & Surge Coil Blueprints – Current Farm Routes

Both the Canto SMG and the Surge Coil trap are still farmable in ARC Raiders, and neither one requires Flashpoint to be running. Canto’s blueprint drops from First Wave Raider caches during the Hurricane map condition. Surge Coil’s blueprint drops from any container during an Electromagnetic Storm, with Dam Battlegrounds the best map to hunt it on. Flashpoint (patch 1.22.0) is where they were introduced, not a window you missed — the conditions they key off are part of the normal rotation.

This guide covers where each blueprint actually drops on the current build (Hotfix 1.36.1, July 9, 2026, inside the Riven Tides period), the exact crafting recipes and stations, and an honest read on how they perform now that the roster has moved on.

Check the condition before you queue

Both blueprints are gated on world modifiers, so the first habit to build is reading the mission select screen before you drop.

• Canto: Hurricane condition, then First Wave Raider caches specifically.
• Surge Coil: Electromagnetic Storm condition. EM Storm can run on Dam Battlegrounds, Spaceport and The Blue Gate — confirm it on the Topside map / event timers before deploying.

Focus one blueprint at a time. Swapping between Hurricanes and Storms makes it impossible to tell whether your route is working or your luck is bad.

How to get the Canto blueprint

Hurricane maps and First Wave caches

Hurricane maps are loud and messy — heavy wind, cut visibility, faster shield drain. The payoff is that they spawn First Wave Raider caches, which are the only confirmed source of the Canto blueprint. No current guide has established a normal-container drop path for it.

• Appearance: small grey-yellow cases with industrial markings.
• Audio cue: a faint electronic hum or beep when you close on one.
• Placement pattern: near First Wave fighting positions — barricades, small camps, crashed equipment, roadblocks.

The mistake almost everyone makes first is looting every generic crate and assuming it is a random world drop. It is not. Until you are deliberately hunting caches, you can run a lot of Hurricanes for nothing.

Building a cache circuit

Exact spawns vary per map, but cache behaviour is consistent enough to build a loose loop:

• Drop near Raider-heavy POIs. On the deployment map, aim for entrenched camps, road chokepoints, and facilities with visible patrol routes.
• Move combat site to combat site. Caches sit just off the main fight — behind sandbags, beside portable generators, near destroyed vehicles.
• Clear, then sweep. Resolve the fight, then do a slow 360 with everyone listening for the hum.
• Check verticality. Balconies, catwalks and the second floors of small structures overlooking roads are consistently under-searched.

In a trio, split sectors: one on high ground, one circling vehicles and cover, one on power and comms equipment. That is meaningfully faster than fanning out at random.

Extraction is the unlock

The blueprint drops straight into your inventory, but it is not permanently learned until you extract back to Speranza. Die on the way out and the run is gone. If a squadmate loots it, they need their own successful extraction for it to count for them. When it drops, stop looting and leave — Hurricane snowballs fast when you overstay with a draining shield.

Crafting the Canto

Back in Speranza, the Canto appears under SMGs at Gunsmith Station level 3.

Material	Quantity	Where to get it
Advanced Mechanical Components	2	Dismantle higher-tier weapons you are not using; loot machinery- and vehicle-heavy sites
Magnet	5	Very common — toolboxes, industrial containers, storage near power equipment
Medium Gun Parts	3	Break down medium weapons you have outgrown instead of selling duplicates

Once it is learned you can build as many copies as materials allow, so you are never risking your only one on a bad raid.

How to get the Surge Coil blueprint

Electromagnetic Storm, and the correction most guides need

Surge Coil is tied to the Electromagnetic Storm condition — constant lightning, HUD interference, unstable electronics. Here is the part a lot of older write-ups get wrong, this site’s previous version included: the blueprint is not restricted to locked or high-value rooms. It can drop from essentially any searchable container while the storm is active — lockers, desk drawers, cupboards, industrial crates, explosive containers, residential boxes, even trash cans. Locked rooms are worth doing because their overall loot density is higher, not because they are the only place the blueprint spawns.

Practically, that means the winning strategy is volume: loot everything, everywhere, for the whole storm.

Where to farm it

Dam Battlegrounds is the map that shows up in every credible guide and player report. The spots that come up repeatedly:

• Testing Annex
• Water Treatment Facility
• Hydroponic Domes
• Research and Administration building and the control tower — high locker and drawer density
• Electrical Substation

Spaceport and The Blue Gate also run EM Storm and are valid, but Dam is where the documented finds cluster. As with Canto, the unlock only sticks once you extract.

Crafting the Surge Coil

Once learned, it sits at Explosives Station level 3 under deployables.

Material	Quantity	Where to get it
Electrical Component	1	Scavenged, craftable at Refiner 1 from Plastic Parts + Rubber Parts, or bought from Celeste for Seeds
Sensor	1	Technological-tagged areas; drops from Snitches and Surveyors, sometimes Androids and server racks; also sold by Celeste
Hornet Driver	1	Looted from Hornet ARC remains — common on every map

Hornet Drivers are the usual bottleneck, purely because people sprint away from Hornet wrecks instead of looting them. Slow down for two seconds after the kill, especially in storms when you are already itching to leave.

Worth knowing: the Surge Coil is also a turn-in item, with 1x Surge Coil required for the Safe Harbor quest, so it is not purely a combat gadget.

How they actually perform

Canto

Canto is a rare SMG that uses medium ammo, and the fairest current read is that it is a solid alternative to the Bobcat rather than a new best-in-slot. Community consensus lands on “worth chasing, not meta-defining.” It is a close-quarters tool: controllable recoil, strong hip-fire, excellent inside buildings and around cover, and a sharp falloff at range.

• Burst at anything past very close range — the medium ammo drain is real.
• Aim for weak points and flanks instead of centre-mass mag dumps.
• Carry a long-range secondary. A marksman rifle or DMR stops you burning Canto ammo on targets you will not kill.

It pairs naturally with lightweight armour and mobility builds, which is exactly what Hurricane maps reward when wind and shield drain are already working against you.

Surge Coil

Surge Coil is a rare deployable trap that pulses electrically when an enemy enters its radius, stunning them briefly. It is consumed on use. Embark has not published damage, radius or stun-duration numbers for it, and no reliable third-party source has measured them — if you see exact figures quoted somewhere, treat them as unverified. What is consistent across every account is that the value is in the stun window, not the damage. It is crowd control you can place.

Placement that works

• Chokepoints. Doorways, stairwells and narrow alleys. Drop one just inside and kite enemies through it.
• Objective defence. Ring uplink consoles so incoming waves get stunned before they reach you.
• Flank cover. On a held lane, a coil on your likely flank route gives you both a stun and an audio warning.

The catch is that the pulse does not care whose side you are on. Standing on top of your own coil when someone rushes you means you both eat the stun. Place them slightly ahead of the angle you expect contact from, space multiple coils out so they chain along a route rather than overlapping on your own squad, and call your placements in co-op.

Common mistakes

• Waiting for Flashpoint to come back. It is not a gate. Hurricane and EM Storm are what you need, and both are in normal rotation.
• Only looting locked rooms for Surge Coil. The blueprint can come from any container during a storm. Volume beats selectivity.
• Looting generic crates for Canto. The opposite problem — Canto really is First Wave cache only.
• Overstaying after a drop. No extraction, no unlock. Bank it.
• Using Canto at range. It feels great up close and wastes ammo everywhere else.
• Standing in your own coil. Treat it like a live mine and fight around the edge.

FAQ

Did the Flashpoint event ending lock these out?

No. Flashpoint (patch 1.22.0) introduced them, but acquisition keys off the Hurricane and Electromagnetic Storm map conditions, which still rotate normally. Item databases still list both blueprints as valid on the current build.

Which should I chase first?

Canto, if you want something you will use every raid. Surge Coil, if you are running objectives or co-op where a placed stun changes fights — and it doubles as the Safe Harbor turn-in.

Is Canto better than the Bobcat?

It is a sidegrade with a different feel rather than a clear upgrade. Guides treat it as a rare-quality alternative worth farming, not as a weapon that reshapes the meta.

What are the Surge Coil’s exact stats?

Not published. The wiki and item databases list the recipe and quest use but no damage, radius or stun numbers, so any specific figures circulating are unsourced.

Wrap-up

Commit to one condition, learn its container type, and extract the moment the blueprint lands. Hurricane plus First Wave caches gets you a genuinely good close-range SMG; Electromagnetic Storm plus indiscriminate looting on Dam gets you the best placeable crowd control in the kit.

If you need the Surge Coil for its turn-in, our Safe Harbor walkthrough covers that quest, and the Forgotten Relics event guide is the current merit farm worth pairing these raids with.
