Alloy Steel
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
Reinforced Leather Strips earns cargo space when your next trampler upgrade is finally asking for rare progression material instead of basic scraps.
Reinforced Leather Strips starts mattering once the cheap part of progression is over and the next real blocker is a late tech-tree cost. It keeps showing up in higher-tier cannon lines, cargo upgrades, and royal chassis progression, which is why one stack can matter more than it looks at first glance. It still should not be auto-kept. If the crew is short on fuel, heals, repairs, or live ammo, those survival slots beat hauling rare material that will never make it home.
It shows up as a rare resource and stays valuable because higher-tier cannon, cargo, and chassis upgrades keep asking for it.
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.
It pays off when one stack removes a real progression wall, especially in the higher tech-tree tiers where cannons, cargo, and chassis upgrades start asking for it repeatedly.
Loose materials are easy to overcarry. If no recipe or trade plan needs it, that slot is better as ammo, healing, repairs, or higher-value loot.
It is worth carrying out when your next blocker is a higher-tier cannon, cargo, or chassis upgrade that already asks for it.
It should lose that fight when the crew still needs fuel, healing, repairs, live ammo, or safer high-payout loot more than future progression material.
