If you want reliable Augment Blueprints on Arc Raiders, Stella Montis is one of the best maps to farm. The reason is simple: it gives us two high-value key rooms in one route, and both become much stronger in night raids. The best results come from combining those rooms with nearby black boxes, metal containers, and medical drawers instead of rushing straight to the key door.

Best Blueprint Spots on Stella Montis

If we only care about consistent blueprint farming, these are the spots that matter most:

The table tells the whole story: Checkpoint is the main target, Archives is the best follow-up, and the surrounding containers raise your odds even more.

Why This Route Works

This route is strong because it stacks multiple high-value container types in a short loop.

Best reason to farm here

We are not relying on one lucky room. We can chain:

• Security Checkpoint
• Security Bridge black boxes
• Archives-side medical drawers
• Archives key room

That means even if one room misses, the run can still pay off.

Night raid matters more than people think

In repeated runs, night raids consistently outperform day raids for:

• Blueprint drop rate
• Total loot density
• Key efficiency

If you have these keys, save them for night whenever possible.

Best Room #1: Security Checkpoint

This is the most reliable room on the map for Augment Blueprint farming.

Why it's the best

The room and its surroundings give access to:

• Metal containers
• Black boxes
• High-value drawers and lockers

In practice, this is the room we would trust most if we wanted one blueprint-focused run.

Best way to run it

1. Check the outside containers first

2. Loot nearby black boxes and drawers

3. Open the key room

4. Clear everything before rotating out

If you find a blueprint early, that usually means the raid is worth pushing harder.

Best Room #2: Archives Storage Room

Archives is the second-best blueprint room and has a solid backup value even when the blueprint does not show.

Why it's worth bringing the key

This area can still return:

• Blueprints from nearby drawers
• Trinkets
• Weapons
• Bags
• Medical loot

So even a miss often still feels decent.

Day vs night

The takeaway is easy: Archives is a night-raid key room first, a day-raid room second.

Best Loot Order Before Using Keys

The biggest mistake is opening the key room too early.

Better order

• Check black boxes
• Check metal containers
• Check medical drawers
• Then use the key

Why does this matter? Because if early loot already shows a blueprint, the raid often feels better overall, which makes your key investment more efficient.

Recommended Route

This route works because it adapts to the spawn instead of forcing the same path every match.

Common Mistakes

These are the mistakes that usually lower blueprint value:

• Using rare keys in day raids
• Ignoring black boxes
• Opening the key room before checking nearby loot
• Leaving breakable or secondary containers unopened
• Forcing the same route regardless of spawn

If you fix those five mistakes, your farming gets noticeably better.

FAQ

What is the best Augment Blueprint room on Stella Montis?

Security Checkpoint is the best overall room. Archives Storage Room is the best secondary option.

Should we only use these keys at night?

If your goal is Augment Blueprints, yes. Night raids are much more efficient.

What should we check before opening a key room?

Prioritize:

• Black boxes
• Metal containers
• Medical drawers

These help you judge whether the raid is worth committing a key.

Is Archives still worth it without a blueprint?

Yes. It can still drop useful gear, trinkets, and support loot, especially if the run is already going well.

Summary

For Stella Montis, the cleanest blueprint route is Security Checkpoint first, Archives second, with black boxes and medical drawers checked before both. If you run these keys at night and avoid rushing the doors too early, you give yourself the best chance of leaving with an Augment Blueprint instead of just another average loot run.
