100 Days At Sea Beginner Survival Guide

Your first hours in 100 Days At Sea determine whether you reach Day 100 or respawn endlessly on Starter Island. Stranded Devs throws you onto a raft with basic tools, empty stomach, and rising night threats. This beginner guide covers Days 1–10: gathering Wood and Stone, crafting essentials, surviving nights, picking Sailor or Survivor, and redeeming codes before you waste daylight. Master these fundamentals before islands travel to Desert Island Sand Worm and bosses summons.

Day 1 — Spawn and Codes

Spawn on Starter Island dock. Open inventory — note starting tools. Redeem active codes via how to redeem: SEAADVENTURE, STRANDEDDEVS, 100DAYS from codes. Spend zero Pearls day one — observe free Sailor boat handling passive first.

Gather Wood and Stone immediately. Craft Fishing Rod (5 Wood + 3 Rope + 1 Hook) and Bonfire (5 Wood + 3 Stone + 1 Flint) from crafting. Fish for food — hunger kills faster than sharks on Day 1.

Open STRANDEDDEVS Companion Chest with inventory space. Equip best roll per companions — Frog for hunger, Turtle for health, Shark for future melee.

Days 2–4 — First Raft and Jungle Sail

Craft Wooden Raft (10 Wood + 5 Rope) — mobile base mandatory before ocean travel. Expand inventory with early gathering on Starter Island Coconuts and Stone.

Learn controls from controls: movement, inventory, raft boarding, Bonfire cooking. Cook every fish — raw fish less efficient than cooked meals.

Sail to Jungle Island when Wooden Raft complete and Bonfire stocked. Gather Tropical Fruit, Vines, and Wood. Jungle has no boss — safe farming zone per islands.

Craft Raft Expansion (15 Wood + 8 Rope + 5 Nails) before extended Jungle sessions. Camper class (+10% building speed) accelerates if you spent 100DAYS Pearls on unlock.

Days 5–7 — Grinder and Medkit Stock

Optional Desert Island scout for Scrap Metal if confident — otherwise continue Jungle food stock. Grinder (10 Scrap Metal + 5 Stone) requires Desert resources; delay until Day 7–10 if unprepared.

Craft Medkits (5 Cloth + 3 Herbs + 1 Alcohol) — stock five before any boss attempt. Medic class Medkit starter helps but batch crafting still required.

Merchant class (+20% sell price) on Jungle vendor flips funds future class unlocks. Survivor (20 Pearls) best first Pearl spend if Sailor feels limiting.

Days 8–10 — Desert Island Prep

Before Desert Island Sand Worm: craft Flintlock Pistol (10 Iron + 5 Gunpowder + 3 Wood) OR unlock Cowboy (35 Pearls) or Sharpshooter (55 Pearls). Ranged weapon mandatory per bosses.

If skipping Desert temporarily: farm Shipwreck Island Iron first via early sail — risky without Medkits. Standard route: Desert Sand Worm then Shipwreck Ghost Captain per survive day 100.

Co-op friends: redeem codes individually, pick complementary classes from tier list — one Crewmate, one combat, avoid four Sailors without roles.

Beginner Mistakes to Avoid

Skipping codes redemption — BERMUDA expired skin on expired proves limited-time rewards vanish.

Sailing at night without Bonfire warm food stock — night hunger and cold chip damage compound.

Spending 100DAYS Pearls on Fire Mage (80) or Ancient Squid (80) before learning basics — bank toward Survivor or Medic.

Melee-only Sand Worm attempt — bring Flintlock Pistol or ranged class.

Ignoring how to play mechanics before rushing Desert Island.
