What to know
-
Prioritize building the Refiner first to craft essential components like electrical parts and antiseptics for other upgrades.
-
Use Stella Montis Seed Vault for bulk basic resources such as metal, plastic, rubber, and seeds tradable with Celeste.
-
Combine runs in villages and medical areas to gather multiple items like collars, cat beds, and laboratory agents efficiently.
-
Leverage events like electromagnetic storms for rare drops from couriers, probes, and husks.
Start your expedition wipe strong by focusing on workbench upgrades in a smart sequence. This approach lets you gather resources from overlapping locations, cutting down raid time to just a few hours in Arc Raiders.

|---|---|---|
| Scrappy | Bluegate Village, Dam, Stella Montis | Fruits (lemons, apricots, olives, prickly pears), pet items (collars, cat beds, pillows), mushrooms |
| Refiner | Stella Montis Seed Vault | Metal, arc power cells, toasters, fireballs, motors, arc circuitries |
| Utility Station | Stella Montis, Dam, Buried City | Plastic, damaged heat sinks, snitch scanners, leap pulse units |
| Explosives Station | Stella Montis, Buried City Hospital | Synthesized fuel, laboratory agents, crude explosive compounds, rocketeer drivers |
| Medical Lab | Stella Montis, Buried City Hospital | Fabric, tick pods for arc alloy, cracked bio scanners, antiseptics |
| Gear Bench | Stella Montis Sandbox, Dam | Power cables, hornet drivers, industrial batteries, bastion cells |
| Gunsmith | Stella Montis Sandbox, Dam buses | Rusted tools, mechanical comps from shredders/rovers, rusted gears, sentinel firing cores |
Best spots for Scrappy upgrades
Head to Bluegate Village for collars, cat beds, and pillows in residential houses.

Grab lemons, apricots, and olives near the olive grove or village outskirts. Pick prickly pears in Dam around extracts, and mushrooms at Spaceport pipelines or Stella Montis cafeteria with a battery door.
How to upgrade Refiner fast
Loot metal, rubber, plastic, and seeds from Stella Montis Seed Vault—two quick trips cover basics.

Farm arc power cells from any arc kills like wasps in Atrium. Snag toasters in Bluegate houses or cafeteria cabinets, fireballs scattered in Stella Montis lobby and Seed Vault, motors from green containers south of Seed Vault and rovers inside.

Get arc motion cores and circuitries from electromagnetic events, prospecting probes, or bastions. Bombardier cells appear guaranteed in Spaceport or Dam night raids.
Step-by-step Refiner path
Step 1
Spawn into Stella Montis, grab a battery, enter Seed Vault for metal stacks and seeds.
Step 2
Kill arc for power cells while looting; safe-pocket motors from containers and rovers.
Step 3
Run electromagnetic event for motion cores; hit Spaceport for bombardier cells.
Step 4
Refine seeds at Celeste into missing basics; craft higher tiers once level 1 is up.
How to max Utility Station
Plastic comes from Seed Vault containers. Damaged heat sinks, motherboards, and power cables spawn in Stella Montis control towers A and B—zip line up for tables full of them. Craft electrical comps in Refiner using Seed Vault loot. Aggro snitches from Bluegate or Buried City towers for scanners (three per wave, respawn every four minutes). Hunt leapers in Dam battlegrounds night/electro for pulse units. Chemicals from Seed Vault or Celeste trades.
Explosives Station upgrade guide
Synthesized fuel hides in Stella Montis carts near lobby, atrium battery door, and rocket thrusters (scrap for two each).

Laboratory agents fill Buried City Hospital drawers or Dam testing annex medical rooms.

Crude explosives from killing four pops or refining Seed Vault chemicals. Hit Security Bridge gray cabinets and duffel bags for five explosive compounds in one run; extra in Seed Vault control admin gray containers. Loot rocketeer husks in Dam electromagnetic or husk graveyard modes.

Step-by-step Explosives path
Step 1
Stella Montis carts and thrusters for fuel; breach security for compounds.
Step 2
Buried City Hospital for agents; Dam medical spots as backup.
Step 3
Kill pops anywhere or refine chemicals; electro Dam for rocketeer drivers.
Step 4
Combine with Utility runs for arc alloy from tick pods.
Medical Lab quick maxing
Trade Seed Vault seeds to Celeste for fabric; refine into durable cloth. Kill eight ticks in Seed Vault or control tower ceilings for arc alloy via tick pods. Cracked bio scanners litter Stella Montis medical beds or Buried City Hospital floors.

Stock medical kits and antiseptics from hospital drawers—two to three raids while gathering other meds. Loot surveyor vaults from electromagnetic couriers (five in one storm raid).
Gear Bench efficient runs
Sandbox second floor control rooms yield power cables on tables.

Craft electro comps in Refiner. Aggro snitches in Bluegate/Buried City to spawn hornets/wasps for drivers (five snitches call two wasps, one hornet). Dam dome shelves and power gen for industrial batteries. Bastion cells from Dam night raid spawns on pipeline/hydroponics—kill with anvil or trailblazers.
Step-by-step Gear Bench path
Step 1
Sandbox zip lines to control rooms for cables.
Step 2
Snitch aggro on Bluegate tower for drivers.
Step 3
Dam dome open shelves for batteries.
Step 4
Night raid bastions for cells; refine adv. electrics.
Gunsmith final push
Seed Vault for metal parts and rubber trades. Rusted tools guaranteed in Stella Montis Sandbox north control room southeast toolbox.

Mechanical comps from shredder gyros (kill two) and rovers (breach three). Wasp/hornet drivers via snitch aggro. Rusted gears from Dam or Bluegate buses/cars (breach a few). Refine mechanical comps into advanced using Refiner. Sentinel firing cores from electro couriers or Dam sentinels.
