100 Days At Sea Classes & Tier List: Best Builds (2026)

Stat	Value	Reported
Total Classes	23	June 2026
Pearl Range	40–750	Reported costs
Best Starter	Survivor	Solo pick

Overview

100 Days At Sea features 23 reported classes purchased with Pearls in the lobby. Each class grants a starter tool and one or more passive buffs that shape your early-game safety, mid-game economy, or end-game combat potential. Because Pearls persist across runs, choosing the right unlock order has a larger long-term impact than any single-run weapon drop.

This page provides two things: a role-first tier list for spending Pearls efficiently, and a complete reference table of every class with reported costs and buffs. Exact Pearl costs and tool descriptions should be confirmed in the lobby Classes menu after each patch.

Tier Rankings Explained

Tier	Meaning
S	Role-defining — the safest first pick or strongest in its niche
A	Strong role performers — excellent for their specific job
B	Solid situational picks — good value when paired with the right strategy
C	Niche or expensive — usable, but rarely the best Pearl investment early

S Tier — Role-Defining

Survivor

Reported cost: 50 Pearls
Starter tool: Chowder
Buffs: Faster regeneration, extra oxygen, and reduced hunger

Survivor is the safest first unlock for solo players. The slower hunger drain and extra oxygen underwater forgive the two mistakes that kill most new runs: forgetting to eat and misjudging a swim back to the raft.

Medic

Reported cost: 60 Pearls
Starter tool: Medkit
Buffs: Faster health regeneration

Medic shines in co-op. Faster regen and a starting Medkit turn close-call revives into recoveries. Even solo, the starter Medkit is valuable before you can craft your own.

Fire Mage

Reported cost: 750 Pearls
Starter tool: Magma Staff
Buffs: 50% more Magic Damage

Fire Mage is the endgame magic option. The Magma Staff starter weapon and magic damage buff make Volcano runs and night ghost-pirate waves far safer — but only after you have iron armor and obsidian routes. Do not rush this as a first unlock.

A Tier — Strong Role Performers

Sailor

Reported cost: 40 Pearls
Starter tool: None
Buffs: Faster top speed on all boats and better boat handling

Sailor saves real time on multi-island seeds. Once you are comfortable with hunger and thirst management, faster sailing lets you chain resource trips and boss kills more efficiently.

Crewmate

Reported cost: 60 Pearls
Starter tool: Flintlock
Buffs: 10% more gun damage

Crewmate is the cheapest reliable gun start. A Flintlock plus a small gun damage buff makes early night defense and island crab cleanup much safer than harpoon melee.

Swordsman

Reported cost: 250 Pearls
Starter tool: Machete
Buffs: 50% more melee damage and 20% extra health

Swordsman clears island trash mobs quickly and the health buffer reduces punishing mistakes. Strong pick once you have your first 250 Pearls and want to shift from survival to combat efficiency.

Knight

Reported cost: 380 Pearls
Starter tool: Claymore
Buffs: Knight Armor, 30% more damage reduction, and 15% faster sprint

Knight is the tank option for players who prefer to trade hits rather than kite. The damage reduction and sprint speed make boss phases and ghost pirate chokes more forgiving.

B Tier — Situational Value

Camper

Reported cost: 70 Pearls
Starter tool: Good Sack
Buffs: +10% health

A cheap health bump and extra storage. Fine as a stepping stone, but Survivor covers more early-game problems for fewer Pearls.

Adventurer

Reported cost: 250 Pearls
Starter tool: Giant Sack
Buffs: 15% increased health and reduced hunger

Adventurer blends storage and survival. Good for players who make long island hauls, but the Giant Sack advantage fades once you craft better storage.

Olympian

Reported cost: 250 Pearls
Starter tool: None
Buffs: 25% faster sprinting and 20% extra health

Olympian is a movement specialist. Strong on large seeds where you spend a lot of time on foot, but less impactful than Sailor on the water.

Battle Buku

Reported cost: 250 Pearls
Starter tool: Poku Poku
Buffs: 25% more melee damage and discount from MukuMuku

A melee-economy hybrid. The vendor discount can pay off over many runs, but only if you consistently use that merchant.

Cowboy

Reported cost: 300 Pearls
Starter tool: Revolver
Buffs: 15% more health and 33% higher gun damage

Cowboy is a direct upgrade to Crewmate for gun-focused players. The Revolver and gun damage buff make island combat and night defense comfortable, but 300 Pearls is a meaningful investment early.

Soldier

Reported cost: 300 Pearls
Starter tool: Assault Rifle
Buffs: 20% faster sprinting

Soldier pairs a strong ranged starter with movement speed. Best once you have a reliable ammo supply from Desert gunpowder runs.

Merchant

Reported cost: 350 Pearls
Starter tool: 100 Doubloons
Buffs: 25% more Doubloons

Merchant accelerates economy badges and merchant purchases. Only worth it after you understand island routes and trader timing.

Sharpshooter

Reported cost: 400 Pearls
Starter tool: Flintlock
Buffs: Faster reload and 50% more gun damage

Sharpshooter is a pure gun DPS class. Strong in the right hands, but the 400-Pearl cost makes it a luxury pick compared to Crewmate or Cowboy.

Millionaire

Reported cost: 400 Pearls
Starter tool: Luxury Yacht and 100 Doubloons
Buffs: Spawn with a Jumbo Luxury Yacht

Millionaire skips early raft building with a large starter boat. Fun and fast for experienced players, but it does not teach the survival skills needed when the yacht eventually needs repairs.

Treasure Hunter

Reported cost: 500 Pearls
Starter tool: 100 Doubloons
Buffs: Five more stack slots and 25% more Doubloons

Treasure Hunter rewards players who already loot efficiently. The extra stack slots are quality-of-life; the Doubloon buff helps with long-term economy.

Pirate

Reported cost: 500 Pearls
Starter tool: Blunderbuss
Buffs: Better boat handling and 50% higher gun damage

Pirate is a direct combat upgrade over Sailor for players who want both mobility and gun damage. Expensive for the early game.

Zookeeper

Reported cost: 600 Pearls
Starter tool: Machete
Buffs: Supercharges companions

Zookeeper only pays off if you have invested in companion chests. Pair it with the Companions page to decide whether the pet synergy is worth 600 Pearls.

C Tier — Niche or Expensive

Hero

Reported cost: 600 Pearls
Starter tool: Holy Sword
Buffs: 25% more health but 25% less hunger

Holy Sword is a powerful late-game weapon, but the hunger downside makes early survival harder. Better as a late unlock for players who already have food systems solved.

Battle Bunny

Reported cost: 700 Pearls
Starter tool: Egg Bomb
Buffs: Egg Grenades from enemies and chests, double jump, 20% faster sprinting

Battle Bunny is a mobility-gimmick class. Double jump and egg grenades are fun, but 700 Pearls buys more raw survival power elsewhere.

Raider

Reported cost: 750 Pearls
Starter tool: Dual Pistols
Buffs: Hold more ammo every five kills, killed enemies drop ammo, 15% faster sprinting

Raider rewards aggressive kill chains. Strong for players who never stop fighting, but overkill for cautious survival play.

Ancient Squid

Reported cost: 750 Pearls
Starter tool: Squid Laser
Buffs: 15% more sprint speed

The Squid Laser is a novelty weapon and 15% sprint speed is available cheaper on Olympian. Only pick this if you value the theme or specific utility.
