Alloy Steel
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
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 starts looking good once the next craft, trade, or research step clearly wants the higher-grade textile input. That is the whole decision. If no recipe is waiting, Fabric becomes another polite-looking stack that loses to fuel, healing, repairs, and the ammunition the crew is about to spend.
Found through specialized boxes.
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 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 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 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 earns a slot when the next recipe already needs full Fabric and you are not carrying it on speculation.
When no recipe is waiting for it, Fabric slips behind the supplies that keep the run stable and the Trampler moving.
Fabric is worth keeping when the next recipe already needs the higher-grade textile input and that stack will be spent soon.
Fabric comes from specialized boxes.
