Alloy Steel
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
Leviathan Meat is the easier Leviathan material to justify, because Food Crates drop it and each stack still sells for 14 Crowns per piece at the pawn shop.
Leviathan Meat is worth keeping when the run can spare cargo for a material that still has clean pawn-shop value. It is an Uncommon T2 resource with a 14-Crown payout, so it is not throwaway filler, and the easier Food Crate source makes it more replaceable than route-only materials. If the Trampler is still short on heals, fuel, repairs, or combat ammo, those survival slots still come first.
It drops from Food Crates and appears in six decoded Food Container drop tables, with cross-linked overlap at Crates And Barrels 7 POI.
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
Coral Chunk feels useful early because you keep finding places to spend it instead of watching it rot in storage.
Coral Dust starts feeling good the moment you realize it is not random filler and actually feeds ammo people want to craft.
Fabric matters when the next recipe has already moved past scraps, so it wins the slot only if a higher-grade textile input is actually waiting.
Fabric Scraps only deserve cargo space when a live recipe still accepts scraps; otherwise they lose to fuel, heals, and ammo fast.
Gunpowder is a keep-or-drop material, and it wins the slot only when ammo or explosive crafting is already part of the plan.
High-Grade Gunpowder earns cargo space only when a real craft or trade plan already needs it more than the survival stacks competing for the same slot.
Leviathan Skin is the Leviathan material to route for when your path already hits coral, wreck, or Living Sand Jr POIs and you still want a 14-Crown resource stack on the way out.
It feels worth the slot once cargo is stable, because Food Crates can feed a stack quickly and every piece still turns into 14 Crowns if the craft plan changes.
Do not let it crowd out survival gear. Even with a clean pawn-shop payout, Leviathan Meat loses the slot to heals, fuel, repairs, and combat ammo when the run is under pressure.
Yes, when cargo is stable and you can use an Uncommon T2 material that either feeds a craft plan or sells for 14 Crowns each.
It loses priority when the same cargo slot is needed for fuel, healing, repairs, ammo, or loot that pays better than another stack of 14-Crown meat.
