100 Days At Sea Map Guide
The world of 100 Days At Sea spans eight distinct islands across increasing difficulty tiers, each gating resources, bosses, and storyline progression toward Day 100 on Bermuda Island. Stranded Devs designed ocean travel between Starter Island, Jungle Island, Desert Island, Shipwreck Island, Volcano Island, Ice Island, Kraken Zone, and Bermuda Island as the core exploration loop. This hub links island breakdowns, boss mechanics, seed routing tools, and gear requirements so you sail efficiently with classes from tier list and gear from crafting.
World Structure Overview
Eight major islands form the progression spine. Starter Island (Safe) teaches basics. Jungle Island (Easy) supplies food. Desert Island (Medium) introduces Sand Worm. Shipwreck Island (Medium) gates Iron for mid-game crafting. Volcano Island (Hard) demands fire resist for Lava Guardian. Ice Island (Hard) punishes cold without warm food. Kraken Zone (Very Hard) requires co-op-grade gear for Kraken. Bermuda Island (Very Hard) hosts Bermuda Entity endgame.
Six bosses block key progression: Sand Worm on Desert Island, Ghost Captain on Shipwreck Island, Lava Guardian on Volcano Island, Frost Giant on Ice Island, Kraken in Kraken Zone, Bermuda Entity on Bermuda Island. Jungle Island and Starter Island have no major bosses — safe farming zones.
Ocean routes between islands consume time, food, and raft durability. Sailor class faster boat handling and Olympian swim speed reduce transit costs. Plan routes using seeds and seeds before committing Pearls to wrong island order.

Recommended Island Order
Standard route: Starter Island → Jungle Island → Desert Island (Sand Worm) → Shipwreck Island (Ghost Captain) → Volcano Island (Lava Guardian) → Ice Island (Frost Giant) → Kraken Zone (Kraken) → Bermuda Island (Bermuda Entity).
Skip conditions: never skip Shipwreck before Volcano — Iron Armor requires Shipwreck Iron. Never enter Ice Island without warm food from Bonfire cooking per beginner survival. Kraken Zone without Scoped Rifle tier weapon wastes repair kits.
Co-op can parallelize: one team farms Jungle while another preps Desert Sand Worm mats. Coordinate via co op strategy and shared seeds layout.
