Alloy Steel
Alloy Steel feels worth the slot when a real craft, upgrade, or sale plan is already waiting for it after extraction.
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.
Leviathan Skin is worth keeping when the route already overlaps the POIs that spawn it, because it carries the same 14-Crown payout as Leviathan Meat without coming from the same easy crate lane. Skin shows up across coral, wreck, ship, and Living Sand Jr-linked POIs, so it rewards a map route more than a crate-opening plan. If the run is already low on space or survival gear, that slot is still better spent on what keeps the Trampler alive.
It appears across many POIs, including Living Sand Nest, Living Sand Jr Coral 1, Destructible Coral Rocks, Ship Graveyard, and multiple shipwreck and rock-group templates.
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 feels worth carrying when the run is already passing coral and wreck POIs, because that turns route overlap into extra material value instead of a separate detour.
It is still loose cargo. If the route is already cramped or the next rooms need heals, fuel, repairs, or ammo, Leviathan Skin should be one of the first materials to cut.
Yes, when your route already passes the POIs that spawn it and the cargo plan can spare room for an Uncommon T2 material worth 14 Crowns each.
It loses priority when you have to choose between it and the fuel, healing, repairs, ammo, or better-value loot needed to survive the rest of the run.
