ARC Raiders Soul's Offering Project Guide: Phases, Rewards, and Materials

Soul's Offering is a Player Project in ARC Raiders that arrived with Live Update 2.3.0 on October 27, 2026. The project window ends November 16, 2026. Raiders from Toledo's Vaulto, Ferrovia, and Murteta contradas gather shrine ARC Raiders Materials, then finish by setting off a firework on the Santa Maria Houses rooftop. This guide covers the phase turn-ins, rewards, and the rooftop objective.

Soul's Offering Full Materials Bill

Across Phases 1 to 3 you turn in these totals: 4 Dead Flowers, 2 Rock Salt, 15 ARC Alloy, 1 Expired Respirator, 2 Railway Lantern, 15 Advanced ARC Powercell, 10 Remote Raider Flare, 2 Fancy Plate, 1 Mask Fragment, 1 Insulation Roll, and 5 Fertilizer. Phase 4 has no item turn-in; it uses a Fireworks Box on the Santa Maria Houses rooftop. Phase 3 awards 3 Fireworks Box items for that finale.

Dead Flowers is an Uncommon Trinket (stack 5, 0.5 kg, sell value 640). Rock Salt is an Uncommon Trinket (stack 5, 0.3 kg, sell value 640). ARC Alloy is an Uncommon Topside Material from ARC (stack 15, 0.25 kg, sell value 200). Advanced ARC Powercell is a Rare Topside Material from certain ARC enemies (stack 5, 0.5 kg, sell value 640). Expired Respirator is a Rare Recyclable tagged Medical (stack 3, 2.0 kg, sell value 640). Fertilizer is an Uncommon Nature item (stack 5, 0.4 kg, sell value 1000). Railway Lantern is a Rare Trinket (stack 3, 0.5 kg, sell value 3000). Fancy Plate and Mask Fragment are Epic Trinkets (stack 3, 0.5 kg, sell value 7000 each). Insulation Roll is an Epic Recyclable (stack 3, 0.5 kg, sell value 3000).

Remote Raider Flare is a Common Quick Use item craftable at Utility Bench station level 1 for 2 Chemicals and 4 Rubber Parts per flare (stack 3, 0.2 kg, sell value 270). Ten flares therefore need 20 Chemicals and 40 Rubber Parts. Fireworks Box is a Rare Quick Use craftable at Explosives Bench station level 2 for 1 Explosive Compound and 3 Pop Trigger (stack 1, 0.5 kg, sell value 2000). Those bench levels sit on the same Workshop Ladder path as other station unlocks.

At the listed item weights, all Phase 1–3 materials would weigh about 22.85 kg if carried together. They can be gathered across separate raids.

Phase Materials and Rewards

Phase 1 Construct Vaulto's Offering

Search residential and commercial ground loot for Dead Flowers and Rock Salt. Gather ARC Alloy from ARC activity and selected ARC-part recycling. Keep the Expired Respirator in Medical loot for the project rather than recycling it—Buried City Hospital and Dam Battlegrounds Research & Administration Medical Bay are Heavy Medical pins for that pull.

Phase 2 Construct Ferrovia's Offering

Bank extra Dead Flowers while clearing Phase 1 routes. Search ARC drops for Advanced ARC Powercell—including Bombardier Remains and Bastion Remains—the same ARC Topside loop that feeds other high-value ARC Raiders Items. Hold Railway Lantern from Rare Trinket loot until Ferrovia clears. Remote Raider Flare can be made at Utility Bench station level 1 using the recipe listed above.

Phase 3 Construct Murteta's Offering

Find Fancy Plate and Mask Fragment in Epic Trinket loot—Heavy pins include Grandioso Apartments in Buried City and Hydroponic Dome Complex (Hydrodomes) on Dam Battlegrounds. Reserve Insulation Roll from recyclable loot before other benches claim it; Cielo Sereno Observatory on Pendola Pass is a Heavy pin and Railyard is Above average. Gather Fertilizer from Nature nodes, with Dam Battlegrounds Hydroponic Dome Complex rated Heavy.

Phase 4 Honor The Fallen

On Buried City, head to the Santa Maria Houses rooftop and set off a Fireworks Box. After Phase 3, use a Fireworks Box reward. If you no longer have one, check the Explosives Bench for the replacement recipe listed above. Completing the project grants the Pilgrim Backpack with Color set to Red and Emissive set to On.

Dead Flowers and Rock Salt Routes

Search Grandioso Apartments in Buried City and Old Town or the Railyard in Pendola Pass for Dead Flowers and Rock Salt. The items may not appear on every run. Grandioso Apartments is a Heavy loot pin for both trinkets; Old Town and Railyard on Pendola Pass are Above average. Dead Flowers also shows up across Medical-tagged and open ground containers; Rock Salt leans residential drawers, cabinets, closets, and kitchen storage.

Pair those trinket searches with ARC Alloy and Advanced ARC Powercell farming on the same Topside raids so Phases 1 and 2 move together. Frigate boarding runs still dump Advanced ARC Powercell and related ARC parts when you push the ship loot path covered in the Frigate Amplification Modules write-up. Keep Expired Respirator pulls from Medical crates instead of auto-recycling. Hold Epic trinkets and the Insulation Roll in stash until Phase 3. If a raid ends before you hit the Dead Flowers count, leave Rock Salt in stash rather than selling it for 640 each; Phase 1 requires a total of 2 Rock Salt.

Update 2.3.0 Changes That Affect Project Raids

Emperor containers near the entrance now yield lower-tier rewards, with higher-tier loot placed deeper inside. If you still farm Emperor for high-tier ARC parts while gathering Advanced ARC Powercell and alloy, plan for a deeper push rather than a doorway grab. Flame Spray damage is 13 per second (was 10 per second) and durability drain is reduced by 50 percent, which helps contested residential clears. Heavy Shield base charge is 90 (was 80), a small survivability bump for slower shrine looting routes.
