Desert Island — Medium. Resources: Scrap Metal, Cactus Water, Sand. Boss: Sand Worm. Bring a ranged weapon.

Shipwreck Island — Medium. Resources: Iron, Gunpowder, Ship Parts. Boss: Ghost Captain. Best mid-game Iron source.

Crafting Priority Reference

Early priority: Wooden Raft → Raft Expansion → Bonfire → Fishing Rod. Never sail without food production from crafting.

Mid-game: Grinder for material recycling → Flintlock Pistol for Desert Island boss → Medkit stock for island runs.

Pre-Volcano: Iron Sword and Iron Armor from Shipwreck Island Iron. Lava Guardian punishes undergeared groups — see bosses.

Late game: Upgrade to Scoped Rifle tier weapons before Kraken Zone. Bulk repair kits and warm food before Ice Island.

Complete recipe trees on crafting. Material farms tied to islands. Camper class (+10% building speed) accelerates raft upgrades per raft building.

Quick Start — First 30 Minutes

Step 1: Launch 100 Days At Sea on Roblox. Step 2: Redeem SEAADVENTURE, STRANDEDDEVS, 100DAYS via how to redeem.

Step 5: Open companion chest at dock; equip pet from companions. Step 6: Read beginner survival before sailing to Jungle Island.

Step 7: Pick Sailor free starter or Survivor (20 Pearls) unless committed to co-op role from tier list. Step 8: Bookmark this wiki for codes refresh and patch tier updates. Step 9: Join friends on same server before progression for shared seeds layout. Step 10: Upgrade weapons before cosmetic raft expansions per raft building.

Common Mistakes to Avoid

Skipping code redemption on Day 1 — expired codes like BERMUDA on expired prove time-limited rewards vanish permanently.

Sailing to Desert Island without a ranged weapon — Sand Worm arena punishes melee-only loadouts from bosses.

Spending Pearls on luxury classes before Day 10 — wastes 100DAYS value; read all classes first.

Entering Volcano Island without Iron Armor — Lava Guardian fire damage wipes unprepared groups.

Ignoring co-op role balance — four DPS without Medic/Crewmate fails Kraken on boss fights.

Trusting random Trello links — no official board; use trello wiki reference instead of scam login pages.

Hoarding Pearls indefinitely — class and companion timing matters mid-game; see survive day 100 spend gates.
