Rock Salt is an Uncommon Trinket in ARC Raiders and a required material for the limited-time Soul’s Offering Project. During the first stage, Construct Vaulto’s Offering, players need two Rock Salt, one Dead Flowers trinket, 15 ARC Alloy, and one Expired Respirator.
The most efficient farming route focuses on the Departure Building at Acerra Spaceport. Its second floor contains numerous blue suitcases in a compact search area, making it a practical location for collecting Rock Salt and extracting without spending extra time exploring the map.
Rock Salt Uses, Value, and Project Requirements
Soul’s Offering runs from October 27 to November 16, 2026. Completing its first stage requires several materials, with Rock Salt being one of the main scavenging targets.
| Item Detail | Information |
|---|---|
| Rarity | Uncommon Trinket |
| Weight per piece | 0.3 kg |
| Stack limit | 5 |
| Base value per piece | 640 Raider Coins |
| Value of two pieces | 1,280 Raider Coins |
| Project stage | Construct Vaulto’s Offering |
| Rock Salt required | 2 |
| Other requirements | 1 Dead Flowers, 15 ARC Alloy, 1 Expired Respirator |
Each Rock Salt weighs only 0.3 kg, so collecting the two required pieces takes up relatively little inventory space. A focused run can help you complete the Rock Salt portion of the project while leaving room for other required materials.
Best Rock Salt Farming Location: Departure Building
The Departure Building is located on the western side of the Acerra Spaceport main grounds, near the Launch Towers. This high-value commercial and technological point of interest contains a useful concentration of blue suitcases on its second floor.
Rather than searching the entire building, concentrate on this floor. Its suitcase locations form a compact loop, and a thorough sweep can reveal nearly a dozen potential spawns.
Step-by-Step Farming Route
Reach the main entrance. After spawning into a Spaceport raid, head directly toward the Departure Building. Even if you spawn farther away in areas such as East Plains, sprint toward the entrance to begin searching as soon as possible.
Go straight to the second floor. Use the main staircases and skip the third floor. Watch for Fireballs and Shredders patrolling the interior hallways, and avoid or clear these ARC machines as necessary.
Search every blue suitcase along the loop. Check the following locations:
- Near the central pillars and waiting benches at the top of the stairs.
- Behind partition walls.
- On wooden desks inside shuttered office sections.
- Along the inner dark corridors.
- In outer windowed corners overlooking the red exterior overhangs.
- Behind reception desks and around the central open atrium.
Follow the same route each time to reduce backtracking and make sure you check the available suitcase locations before leaving.
Other Items Found During Rock Salt Runs
Blue suitcases can contain more than Rock Salt. Additional loot may include Faded Photographs, Rope, Duct Tape, Sensor Parts, and the Pendola Pass Old Town Key.
| Item | Type |
|---|---|
| Faded Photographs | Collectible loot |
| Rope | Resource |
| Duct Tape | Resource |
| Sensor Parts | Components |
| Pendola Pass Old Town Key | Key |
Players collecting ARC Raiders Items can use the Departure Building route to search for Rock Salt while gathering other useful resources. Keep the project’s remaining requirements in mind when deciding which additional items deserve backpack space.
Collectors also working toward ARC Raiders BluePrints can plan separate collection runs around their broader goals. For Rock Salt, stick to the blue suitcases on the second floor of the Departure Building.
Fast Extraction Through the West Elevator
Once you have searched the second floor, leave through the western side of the Departure Building and head to the nearby West Elevator.
- Finish checking the blue suitcases.
- Confirm that you have collected the Rock Salt you need.
- Exit toward the western side of the building.
- Activate the West Elevator terminal.
- Extract to Speranza.
The elevator’s proximity makes it a convenient way to end a targeted run. According to the supplied route, a thorough second-floor sweep yields around two Rock Salt on average, enough to meet the first stage’s Rock Salt requirement in one run when the expected drops are obtained.
Zero-Gear Rock Salt Farming Strategy
A zero-gear setup offers another approach for players who want to focus on Rock Salt collection while minimizing the equipment they bring into a raid.
Prepare Your Safe Pocket
Deploy without weapons or armor equipped while keeping the Safe Pocket active. Place a few Adrenaline Shots inside it before entering the raid to help with stamina during the initial sprint to the Departure Building.
Secure Rock Salt Immediately
Follow the second-floor route and search the blue suitcases. When you find Rock Salt, transfer it directly into your Safe Pocket so the target items are secured during the run.
Return to Speranza
After securing the required trinkets, head to the nearby West Elevator for extraction. The supplied strategy also describes surrendering through the menu as an alternative way to return to Speranza with Safe Pocket contents intact; confirm this behavior in-game before relying on it.
This method keeps the run focused on the required materials instead of a broader loot expedition. The West Elevator remains the straightforward extraction option when you want to leave through the normal route.
Complete Construct Vaulto’s Offering Efficiently
The Departure Building at Acerra Spaceport provides a focused route for farming Rock Salt. Search the second-floor blue suitcases, check the listed spawn areas, and use the West Elevator when your target items are secured.
For Soul’s Offering, you need two Rock Salt alongside one Dead Flowers trinket, 15 ARC Alloy, and one Expired Respirator. Keeping those requirements in view helps you prioritize useful loot and organize your next run around whatever materials remain.
The combination of a compact search loop, nearby extraction, and a lightweight zero-gear setup makes this route worth considering for Raiders working toward the first stage of Soul’s Offering.
