100 Days At Sea Classes Guide

How Classes Work in 100 Days At Sea

Every player selects or unlocks one class per run. The free Sailor class provides faster boat handling with no starter tool — ideal for learning Starter Island mechanics. Premium classes cost Pearls ranging from 20 (Survivor) to 80 (Ancient Squid, Fire Mage). Class perks stack with companion buffs from companions and gear from weapons and armor.

Progression persists across deaths within a run depending on server rules, but class selection typically locks until you purchase another unlock with Pearls. Treat your first pick as a multi-day commitment unless you redeemed Pearls from codes specifically for experimentation. New players should start with Sailor or Survivor rather than expensive S-tier picks that shine only with full gear.

Co-op teams benefit from complementary roles: Crewmate (+10% team XP) pairs with combat classes, Medic (+15% health regen) sustains raids, and Camper (+10% building speed) accelerates shared raft upgrades per co op strategy. Duplicate DPS classes waste team aura value.

Class Tier Overview

S-tier (50–80 Pearls): Battle Buku, Sharpshooter, Pirate, Hero, Raider, Ancient Squid, Fire Mage — top combat and specialization picks for boss DPS, Kraken Zone, and Bermuda Island. Full rankings on tier list.

A-tier (35–50 Pearls): Medic, Adventurer, Olympian, Swordsman, Soldier, Night, Treasure Hunter, Zookeeper, Battle Bunny — strong mid-game roles with clear island synergies. Soldier tanks Lava Guardian; Adventurer speeds Jungle and Desert scouting.

B-tier (20–35 Pearls): Survivor, Crewmate, Camper, Cowboy, Merchant — budget-friendly utility. Survivor extra oxygen helps underwater nodes; Merchant +20% sell price funds Pearl purchases.

Free tier: Sailor — never underestimate free boat handling for ocean travel between Shipwreck Island and Volcano Island routes on islands.

Choosing Your First Class

Solo beginners: Sailor (free) or Survivor (20 Pearls) for hunger and oxygen comfort on long sails. Redeem 100DAYS from codes for Pearl budget. Read beginner survival before spending on luxury classes.

Co-op beginners: Crewmate for team XP, Medic for sustain, or Camper if designated raft builder. One combat class per two players minimum before Desert Island Sand Worm.

Boss-focused players saving Pearls: bank toward Sharpshooter (55 Pearls) for ranged boss DPS or Soldier (45 Pearls) for Lava Guardian and Frost Giant tanking. Build paths on builds.

Companion synergy: Zookeeper (+25% companion buff effectiveness) multiplies STRANDEDDEVS chest rolls — see companions for Frog through Magma Golem pairings.

Pearl Economy and Class Unlocks

Pearls come from codes (100DAYS = 25 Pearls on codes), Deep Sea Pearls in Kraken Zone, and rare chests on Bermuda Island. Average first S-tier unlock requires multiple code redemptions or mid-game island farming — plan unlock order around boss gates on bosses.

Millionaire (60 Pearls, starts with 500 Coins) skips early economy grind but sacrifices combat perks. Merchant (+20% sell price) earns Coins faster without Pearl sink — compare on all classes before buying Millionaire for shop runs.

Do not unlock Fire Mage or Ancient Squid before Volcano Island unless co-op team lacks AOE or water damage for Kraken prep. Fire Mage AOE clears Jungle Island elites fast; Ancient Squid +25% water abilities shines in Kraken Zone specifically.
