Alloy Steel
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
Mixtures is stash-first loot. It feels worth dragging out only when you already know the recipe or turn-in waiting for it.
Mixtures feels good to keep when you already know where it is going after extraction. If a recipe, upgrade, or trade turn-in is waiting in the stash, the slot makes sense. If the run is still short on reactor fuel, healing, repairs, or the ammo you are about to spend, Mixtures drops behind the supplies that decide whether the haul comes home at all.
You pick it up through normal item and resource loot paths, then decide at extraction whether a real recipe or turn-in is close enough to justify the cargo slot.
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 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.
Mixtures pays off when you already know the next craft, upgrade, or turn-in that will consume it instead of letting it sit in storage.
If no recipe or turn-in is waiting, Mixtures is usually the kind of stack you regret defending. Fuel, healing, repairs, and cleaner payout loot win that argument first.
Yes, when you already know the next craft, upgrade, or turn-in that will spend it.
It loses priority when the run still needs fuel, healing, repairs, matching ammo, or loot with a cleaner cash-out.
