100 Days At Sea Crafting Guide
Crafting at your raft bench drives progression in 100 Days At Sea — every boss gate from Desert Island Sand Worm through Bermuda Entity assumes specific recipes completed in order. Stranded Devs lists core crafts from Wooden Raft through Iron Armor with materials tied to the eight islands. Camper class (+10% building speed) accelerates every recipe below. This guide covers all official craft entries with material sources, priority order, and links to islands farming routes and builds loadouts.
Raft Crafts
Wooden Raft — Materials: 10 Wood + 5 Rope. Tip: Build this first — your mobile base. Source Wood and Stone on Starter Island; Rope from Vines on Jungle Island or early crafting chains.
Raft Expansion — Materials: 15 Wood + 8 Rope + 5 Nails. Tip: Expand for more structures before multi-island day trips. Nails from Scrap Metal processing on Desert Island after Grinder unlock. Camper Extra Wood starter accelerates first expansion per raft building.
Structure Crafts
Bonfire — Materials: 5 Wood + 3 Stone + 1 Flint. Tip: Cook food and stay warm at night. Critical for Ice Island warm meals and Volcano fire resist prep. Craft on Starter Island day one.
Container Shelter — Materials: 20 Scrap Metal + 10 Wood. Tip: Protects from rain and cold on raft during long Kraken Zone and Ice Island approaches. Desert Island Scrap Metal gate after Sand Worm or farming.
Tool Crafts
Grinder — Materials: 10 Scrap Metal + 5 Stone. Tip: Break down items into materials. Unlock after Desert Island Scrap Metal farm — reduces backtracking for Iron and Gunpowder on islands.
Fishing Rod — Materials: 5 Wood + 3 Rope + 1 Hook. Tip: Reliable food without visiting islands. Hook from Starter vendors or early quests. SEAADVENTURE Coins from codes fund hook if short on mats.
Consumable Crafts
Medkit — Materials: 5 Cloth + 3 Herbs + 1 Alcohol. Tip: Heals 50% HP — always carry one. Stock ten before Ghost Captain, Lava Guardian, Frost Giant, Kraken, and Bermuda Entity per bosses. Medic class Medkit starter supplements early stock.
Cloth and Herbs from Jungle Island gathering. Alcohol from vendors or Shipwreck loot. Grinder recycles damaged gear into partial mat refunds on failed boss attempts.
Weapon Crafts
Iron Sword — Materials: 15 Iron + 5 Wood + 3 Leather. Tip: Best mid-game melee weapon. Iron from Shipwreck Island — do not attempt Volcano without melee backup. Battle Buku starts with Iron Sword — skip craft if unlocked.
Flintlock Pistol — Materials: 10 Iron + 5 Gunpowder + 3 Wood. Tip: First ranged weapon for bosses. Mandatory before Desert Island Sand Worm if Sharpshooter not unlocked. Gunpowder from Shipwreck Island.
Armor Crafts
Iron Armor — Materials: 25 Iron + 10 Leather + 5 Cloth. Tip: Craft before Volcano Island. Lava Guardian and environmental fire without Iron Armor wipes unprepared groups. Hero class starts with Iron Armor + Sword — partial skip for 70 Pearl investment.
Leather from island hunts and Grinder recycling. Full Iron Armor set before Lava Guardian summon — partial pieces insufficient for fire tick mitigation on Volcano Island.

Daily vendor stock rotates — check every island dock visit. Coins from codes SEAADVENTURE supplement bad RNG days. Do not pearl-buy common mats unless speedrunning with documented seed on seeds.
