Blueprint farming in Arc Raiders is in a much better place than it used to be. Blueprints are no longer painfully rare, but that doesn’t mean they’re random or brainless to farm. With patch 1.12, Embark appears to have quietly adjusted blueprint rules once again, widening loot pools and making certain locations and events far more reliable than before. This Arc Raiders 1.12 blueprint guide 2026 breaks down how blueprints work, what has changed recently, and how to target farm specific blueprints efficiently.

Arc Raiders 1.12 Blueprint Farm Guide 2026

Based on extensive player reports and community data, patch 1.12 introduced several subtle but impactful changes. Augment blueprints are appearing in unexpected containers, such as car hoods and electrical boxes, which previously did not touch augment loot pools. Trial rewards are now capable of dropping high-tier weapon blueprints, including ARC Raiders items previously tied to specific events like the Bobcat. Key rooms feel more reliable overall, especially when used in high-value locations and during favorable map conditions. While Embark hasn’t officially documented these changes, the consistency of reports strongly suggests blueprint pools have expanded.

The Rules of Blueprints in Arc Raiders 1.12

Blueprints can technically spawn anywhere, but your odds are never equal. Blueprint farming is all about stacking probability. Your chances improve by combining:

• Map modifiers (Night raids, events)

• Location loot value (Yellow / Red outlines)

• Container type (medical, military, residential, etc.)

• Key rooms and key rarity

Night raids increase loot chances globally. Red high-value locations drastically improve rare spawn odds. Key rooms amplify everything further. When these factors stack, blueprint farming becomes dramatically more efficient.

ARC Raiders 1.12 Blueprint Pools 

Blueprints are divided into loot pools, not tied to one exact location. Medical blueprints are more likely from medical containers. Weapon blueprints come from ammo cases, raider caches, weapon crates. Attachments favor commercial and residential containers. A medical container can still appear outside a medical-tagged location, but medical locations simply contain more of them, letting you roll the odds more times. The goal isn’t one perfect container—it’s volume under the right conditions.

How to Farm Blueprints after ARC Raiders 1.12 Patch?

Map Condition & Event-Specific Blueprints

Some blueprints are strongly tied to map events:

Volcano Blueprint - Found during the Hidden Bunker event. Can appear anywhere on the map during the event, not just inside the bunker itself.

Bobcat Blueprint - Most commonly tied to the Locked Gate event. Can drop even outside the checkpoint area, including red lockers before the gate opens.

Snap Hook Blueprint - Appears during Electromagnetic Storm events. Any container can roll it, but dense loot areas perform best.

Tempest & Wolfpack - Most reports come from night raids, with Buried City being a frequent hotspot.

Stella Montis Exclusive Blueprints

After the Expedition update, Embark explicitly tied several blueprints to Stella Montis:

Exclusive drops include:

• Ailion

• Deadline Mine

• Seeker Grenade

• Trailblazer

• Pulse Mine

• Gas Mine

Simply playing on Stella Montis gives you access to this pool. High-value locations and night raids still apply.

Augments & Complex Gun Parts

Augments primarily drop from:

• Medical containers

• Military-style containers (black lockers, black crates, box lockers)

Strong farming locations include:

• Manticore Facility (Bluegate)

• Medical Research Area (Stella Montis)

• Security Areas with armories

Complex Gun Parts blueprints also come from these military containers, making them excellent dual-purpose targets. Recent reports suggest augments can now drop from unexpected container types, meaning luck can strike anywhere—but focused farming is still best.

Medical Blueprint Pool

Medical blueprints include:

• Vita Shot

• Vita Spray

• Defibrillator

Best strategy:

Farm medical containers. Prioritize medical-tagged locations. Run night raids in high-value zones. Medical Research on Stella Montis remains one of the strongest locations.

Weapons & Weapon Parts Pool

This is a large blueprint pool, including:

• Weapon parts (Light, Medium, Heavy)

• Anvil, Toro

• Osprey, Torrente, Ventor

• Batina (Epic)

Sources:

• Raider caches

• Ammo cases

• Weapon cases

• Grenade tubes

• Raider bags

Red high-value locations dramatically improve odds. Uncovered Cache events are also excellent for brute-force farming.

Attachments (Largest Blueprint Pool)

Attachments are the hardest blueprints to target due to sheer pool size.

Best container sources:

• Residential lockers

• Commercial buildings

• Apartments and housing blocks

• Spaceport lockers

• Departure Building locker rooms

Special tip: Surveyors
Breaking Surveyors yields multiple components with blueprint chances. Their core frequently drops attachment blueprints. Seeker grenades make farming them extremely efficient.

Jupiter & Equalizer (Legendary Blueprints)

These come exclusively from the Harvester Event:

• Loot the three reward containers after completion

• Both Jupiter and Equalizer can drop from a single event

• Core of the Queen can also be looted if you’re fast

Trial Blueprints

Trials can reward:

• Augments

• Attachments

• Weapon blueprints

• Rare items like Bobcat

Trials are not reliable for target farming, but excellent for filling gaps when RNG refuses to cooperate.

Quest-Specific Blueprints

Guaranteed blueprint rewards include:

• Trigger Grenade – Sparks Fly

• Lure Grenade – Greasing Her Palms

• Bleta – Industrial Espionage

• Hole Cracker & Launcher Ammo – Major’s Foot Locker

Always complete these quests early.
