If you have spent any significant time grinding the wasteland in ARC Raiders, you already know that the Vita Spray Blueprint is arguably the most stubborn legendary blueprint to track down. Offering continuous health restoration for both you and your squad mates, it is an essential piece of utility gear for high-tier raids. While a few incredibly lucky players manage to stumble across it at level 5, many others find themselves hundreds of hours deep into the endgame without a single drop.

Because the drop chance is rooted heavily in random number generation (RNG), aimless wandering across the maps will only burn through your gear and extraction tokens. To secure the drop efficiently, you need to target specific medical containers—specifically the blue plastic pull-out drawers and the tall, white metal medical cabinets. Here is a realistic, data-backed breakdown of exactly where to look, how to maximize your drop rates, and how to optimize your farming runs.

Top Medical Hotspots and Targeted Farming Runs
The consensus across the community points to three primary high-density zones for medical loot. If you want this blueprint, your strategy should revolve around spawning as close to these landmarks as possible, sweeping the containers, and extracting immediately.

1. Buried City: The Hospital (New District)
The Hospital in Buried City is statistically your highest probability zone due to the shear volume of concentrated medical containers.

The Route: Do not fight your way through the front entrance if you are solo. Use the exterior scaffolding to breach the first and second floors.

What to Look For: Right inside the main storage room just left of the main entrance, and across the second-floor patient rooms, you will find clusters of blue medical drawers.

Real-World Experience: Several raiders report pulling the blueprint on their very first targeted night run here, specifically from the top two floors. One player documented finding it in the third blue drawer they searched on a fresh run, proving that structural efficiency beats random exploration.

2. Dam Battlegrounds: Testing Annex
The Testing Annex at the Dam is another premium hub for targeted grinding.

The Route: Head straight to the southeastern medical building. You will need to clear out roaming Pops and Fireballs patrolling the perimeter before you can safely loot.

What to Look For: Focus your attention on the first-floor circular hallway, which is lined with blue and white medical containers. If you happen to possess a Dam Testing Annex Key, use it to unlock the high-value basement rooms where container density increases by roughly 40%, significantly raising your odds per raid.

3. Stella Montis: Medical Research Center
If Buried City is too contested by aggressive squads looking for weapon cases, Stella Montis offers a quieter but equally lucrative alternative.

The Route: Infiltrate the Med Lab section of Stella Montis while the rest of the lobby fights over the central business centers.

What to Look For: Check both the desk drawers and the tall white storage cabinets in the back archive rooms. Community data notes that while items like the Snap Hook blueprint drop heavily from the white cabinets, the Vita Spray variant actively populates both the tall white units and the smaller blue bins.

Secondary Passive Drop Methods
If running the same loops inside the Hospital or the Annex gets tedious, you can mix up your strategy with these high-tier alternative activities.

Hunting ARC Surveyors: Never look past the floating ARC Surveyors emitting a distinct blue spotlight. Raiders who actively hunt these drones report dropping legendary blueprints over extended sessions. While the drop rate per drone sits in a low single-digit percentage, checking every blue-light surveyor across Spaceport or Blue Gate gives you a reliable passive income of blueprints.

Weekly Trials and Try Hard III: The standard scavenging reward pool occasionally rewards consistent play. The Vita Spray Blueprint has been verified as a guaranteed reward choice for completing specific Level 3 Weekly Trials. If the trial rotations for the week look relatively simple, prioritizing these challenges is a definitive way to bypass container RNG completely.

First Wave Caches and Event Modifiers: Map-wide events change container multipliers drastically. Farming First Wave Caches during heavy weather events like Hurricanes or Cold Snaps yields elevated drop tables for legendary blueprints.

Data Analysis: Day vs. Night Raid Efficiency
While the blueprint can technically drop during standard daytime conditions, running your medical routes during a Night Raid or a Cold Snap modifier dramatically shifts the math in your favor.

Let's look at a conceptual analysis of how raid variables impact your time investment:

Raid Condition Average Med Containers per Run Est. Drop Probability Modifier Target Time per Run Safest Extraction Route
Standard Day Raid 8 – 12 Containers Baseline (1x) 12 Minutes Low-risk Outworld
Night Raid / Event 15 – 22 Containers Enhanced (approx. 1.8x) 8 Minutes Hidden Bunker / Blue Gate
During a Night Raid, high-tier loot containers spawn with a significantly higher density. Instead of checking 10 containers at the Buried City Hospital, an identical run at night can open up over 20 viable drawers and cabinets due to modified layout tables. More importantly, night modifiers reduce overall player visibility, allowing you to slip through exterior scaffolding, hit your medical rooms, and dive down into a nearby bunker or cellar to extract in under 8 minutes.

If you find yourself running out of ammo or constantly losing your gear while hunting for these elusive crafting specs, you might want to buy them outright or acquire professional assistance.

Pro-Tips for Maximizing Your Farming Success
Keep Your Safety Pocket Clear: The Vita Spray Blueprint has a weight of 0 kg but takes up a crucial slot. Ensure you leave a dedicated slot open in your safety pocket before you drop into the raid. If you get pinched by a high-level ARC squad or an ambushing player right after finding it, you will still keep the blueprint even if you fail to extract.

The Spaceport Alternative: If the primary three zones are entirely locked down by hostile squads, check the Trench Tower locked area on Spaceport. Raiders have confirmed finding the blueprint twice in a single evening inside the basement crawlspaces and storage rooms under the main tower.

Listen for the Audio Cues: When farming the Hospital or Testing Annex at night, move slowly. Because medical rooms are enclosed spaces with minimal exits, you are vulnerable to player ambushes. Listen for the distinct sound of metal drawer slides—if you hear a drawer opening and it isn't your teammate, prepare for immediate close-quarters combat.
