In ARC Raiders, Augment blueprints are some of the most valuable items you can extract with. They unlock powerful upgrades that can dramatically improve your survivability and combat performance. However, finding them consistently can be difficult unless you know exactly where to look.
If you're farming on the Stella Montis map, there are two locations that stand out as the best spots for Augment blueprint hunting. With the right strategy—especially during night raids—you can dramatically increase your chances of leaving the raid with rare blueprints.
Why Night Raids Are Better for Blueprint Farming
Before diving into the locations, one key tip: run night raids whenever possible with ARC Raiders Loot for sale.
Night raids generally have:
Higher chances of rare loot
More blueprint drops
Less competition for certain rooms
While you can still find good items during day raids, the overall drop rate for valuable blueprints is noticeably lower. If you have rare keys, it's usually best to save them for night raids.
1. Security Checkpoint Key Room (Best Blueprint Location)
One of the most reliable places to farm Augment blueprints is the Security Checkpoint key room located in the lobby area of Stella Montis.
This room is locked behind the Security Checkpoint Key, which is considered a very rare key, but the rewards can be excellent.
Why This Room Is So Good
Inside the room you will find several:
Metal containers
Black loot boxes
High-value drawers
These containers have one of the highest chances in the map to drop Augment blueprints. Many players report finding at least one blueprint almost every time they open this room.
Extra Trick: Skip the Breach
If you don't want to breach the door, there's a useful shortcut:
Go to the wall next to the checkpoint door
Jump over the barrier
Access the containers inside
This allows you to check the loot without spending breach resources.
What You Can Find Here
Common finds include:
Defensive Augment blueprints
Ventor gear
Rare trinkets
Weapons and attachments
If you are specifically hunting Survivor Augments, this location is one of the best spots in the game.
2. Cultural Archives Key Room (Second Best Spot)
The second-best location for Augment blueprint farming on Stella Montis is the Archives storage room.
This area requires the Archives Key, and it consistently provides strong loot—especially during night raids.
Loot Locations to Check
When entering the archives area, make sure to check:
1️⃣ Medical Drawers
These drawers can spawn:
Defib blueprints
Deadline blueprints
Other Augment items
Sometimes you may even find multiple blueprints in a single run.
2️⃣ Storage Room Containers
At the end of the corridor you'll find the main storage room with:
Wooden crates
Weapon cases
Backpacks
Trinkets
Blueprint spawns
Unlike some wooden boxes outside, these containers can drop high-tier loot, including blueprints.
Blueprint Farming Trick: Check Normal Loot First
A useful strategy many experienced raiders follow:
Loot several normal containers first
If you find a blueprint early in the raid
Then open your key rooms
Why this works:
Sometimes raids seem to have higher blueprint drop pools, meaning if one drops early, the raid may spawn more.
This isn't guaranteed, but it's a pattern many players have noticed.
Additional Loot Spots Near the Business Center
While farming Stella Montis, don't skip nearby areas that can also spawn blueprints.
Good containers include:
Black supply boxes
Metal containers
Briefcases
Computers
Trash cans (surprisingly good for blueprint spawns)
Some players have even found rare items like the Tempest blueprint in trash containers.
Cleaning machines and briefcases are also high-value loot sources, often containing attachments, trinkets, and rare items.
Extra Tips for Efficient Blueprint Runs
Save Keys for Night Raids
Night raids provide better blueprint chances and overall loot density.
Loot Surroundings First
Check nearby containers before opening a key room to increase the odds of a strong loot run.
Don't Skip Small Containers
Trash cans, computers, and briefcases can all spawn rare blueprints.
Clear the Area First
Using a barricade kit or clearing enemies nearby can prevent other players from interrupting your loot run.
Final Thoughts
If you're serious about farming Augment blueprints in ARC Raiders BluePrints,the Security Checkpoint and Archives key rooms on Stella Montis are among the best places to farm them.
When used correctly—especially during night raids—these locations offer some of the most consistent blueprint drops in the game. With the right keys and a bit of luck, you can regularly extract with powerful upgrades.
And remember: if you manage to open both rooms in a single raid, there's an extremely high chance you'll walk away with at least one Augment blueprint.
