All 8 Islands in 100 Days At Sea
Each island in 100 Days At Sea offers unique resources, difficulty ratings, and optional boss encounters that gate your march toward Day 100. Stranded Devs spaced eight biomes from the safe Starter Island tutorial zone through the Very Hard Bermuda Island finale. This guide covers every island's resources, boss assignment, survival tips, and recommended class picks from tier list so you arrive prepared with gear from crafting and codes redeemed from codes.
Starter Island — Safe Zone
Difficulty: Safe. Resources: Wood, Stone, Coconuts. Boss: None. Tip from game data: First stop — gather basics for your raft.
Starter Island is your spawn hub: basic crafting, food gathering, and introductory survival loops. Gather Wood and Stone for Wooden Raft, Bonfire, and Fishing Rod from crafting. Fish and coconuts stabilize hunger during beginner survival Days 1–5. No major boss arena — safe zone for redeeming codes and opening STRANDEDDEVS Companion Chests.
Recommended classes: Sailor (free boat handling for first sail), Survivor (hunger reduction), Camper (Extra Wood starter for raft). Spend SEAADVENTURE Coins on Grinder parts before sailing to Jungle Island.
Jungle Island — Easy Food Loop
Difficulty: Easy. Resources: Tropical Fruit, Vines, Wood. Boss: None. Tip: Great early food and crafting materials.
Jungle Island is the first ocean destination after Starter Island. Tropical Fruit and Vines feed Bonfire cooking chains and rope crafting for Raft Expansion. Wood supplements Starter stock. No boss — ideal for Adventurer (+15% exploration speed) scouting and Merchant (+20% sell price) vendor flips.
Farm here until Fishing Rod and Bonfire sustain hunger without island visits. Pair Treasure Hunter Compass runs with seeds chest routes before pushing Desert Island Sand Worm.
Desert Island — Sand Worm Gate
Difficulty: Medium. Resources: Scrap Metal, Cactus Water, Sand. Boss: Sand Worm. Tip: Bring a ranged weapon.
Desert Island introduces Scrap Metal for Grinder and mid-tier crafting. Cactus Water manages thirst in heat. Sand Worm boss arena demands ranged damage — Cowboy Flintlock Pistol or Sharpshooter Scoped Rifle per bosses. Melee-only Battle Buku runs struggle without ranged backup.
Raider class (+20% damage + raid loot) accelerates Scrap Metal loops. Craft Flintlock Pistol before summon if Sharpshooter not unlocked. See boss fights for Sand Worm phase breakdown.
Shipwreck Island — Iron Hub
Difficulty: Medium. Resources: Iron, Gunpowder, Ship Parts. Boss: Ghost Captain. Tip: Best source of Iron mid-game.
Shipwreck Island is the critical Iron gate. Iron Sword, Flintlock Pistol, and Iron Armor recipes from crafting require Iron gathered here. Gunpowder feeds ranged ammo. Ghost Captain boss tests mixed melee and ranged coordination — Soldier tanks, Sharpshooter DPS.
Do not skip Shipwreck before Volcano Island. Lava Guardian without Iron Armor wipes groups. Night class Lantern helps fog sections if visibility drops during ghost mechanics.
Volcano Island — Lava Guardian
Difficulty: Hard. Resources: Obsidian, Magma Ore, Fire Crystals. Boss: Lava Guardian. Tip: Need fire resistance and Iron Armor.
Volcano Island punishes undergeared players with fire damage and environmental heat. Obsidian and Magma Ore feed advanced weapons. Fire Crystals gate late crafting. Lava Guardian requires Iron Armor from Shipwreck Iron and fire resist food from Bonfire prep.
Fire Mage (+30% fire damage, AOE) dominates mob clears and boss add waves. Magma Chest companions Lava Snail and Magma Golem synergize here. Soldier recommended tank slot per co op strategy.
Ice Island — Frost Giant
Difficulty: Hard. Resources: Ice Crystals, Frozen Fish, Frost Wood. Boss: Frost Giant. Tip: Cold drains health — bring warm food.
Ice Island environmental cold drains health without warm food from Bonfire cooking. Ice Crystals and Frost Wood feed late gear. Frozen Fish provides cold-resist meal buffs when cooked. Frost Giant boss favors ranged weak-point damage — Sharpshooter optimal.
Seagull companion (brings food every 120s) reduces inventory pressure. Medic health regen sustains cold tick damage. Stock Medkits from crafting before landing.
Kraken Zone — Deep Sea Boss
Difficulty: Very Hard. Resources: Kraken Ink, Deep Sea Pearls. Boss: Kraken. Tip: Full crew and S-tier weapons required.
Kraken Zone is open ocean — not a traditional island landing. Kraken Ink feeds endgame mods. Deep Sea Pearls fund S-tier class unlocks. Kraken boss demands four-player co-op with Scoped Rifle tier weapons and Iron Armor minimum.
Ancient Squid (+25% water abilities) and Tentacle Summon starter shine here. Olympian swim speed helps emergency repositioning. Full crew coordination on boss fights Kraken section mandatory for most groups.
Bermuda Island — Final Storyline
Difficulty: Very Hard. Resources: Ancient Relics, Mystery Crates. Boss: Bermuda Entity. Tip: Final storyline — save for last.
Bermuda Island is the Day 100 endgame zone. Ancient Relics craft final-tier items. Mystery Crates roll Pearls and rare loot — Treasure Hunter (+25% chest quality) maximizes value. Bermuda Entity is the final boss before Day 100 completion.
Night (+20% night vision) and Hero (+10% all stats) excel in finale routing. Redeem any remaining active codes from codes before final push — expired BERMUDA skin from expired shows how limited-time rewards vanish.
