What is 100 Days At Sea?

100 Days At Sea is a Roblox open-world ocean survival game by Stranded Devs. You venture into the Bermuda Triangle, collect floating resources with a harpoon, and turn a small raft into a fortified base while trying to survive 100 days.

Exploration takes you across the sea to mysterious islands, where you search for useful gear and face enemies. Raft expansion, resource planning, defense, and preparation for longer voyages form the central survival loop.

100 Days At Sea Classes Tier List

Classes are permanent Pearl purchases with distinct spawn equipment and passives, rather than cosmetic skins. These S–C bands reflect a September 12 TechWiser assessment; its separate D band contains Camper, Medic, and Survivor and is identified explicitly instead of falsely merging it with C.

A

Necromancer, Ghost Hunter, Werewolf, Battle Bunny, Minigunner, Pirate, Sharpshooter, Knight, Cowboy, and Alien Warrior.

B

Soldier, Treasure Hunter, Explorer, Battle Buku, Olympian, Swordsman, Harpooner, Millionaire, Prospector, and Pilot; their niches include looting, travel, guns, and crafting.

C

Merchant, Adventurer, Builder Man, Chef, Sailor, and Crewmate. The cited source places Camper, Medic, and Survivor in a distinct D band, not this C group.
