100 Days At Sea is a popular Roblox open-world survival game where players spawn in the ocean, gather resources (like with a harpoon), build and upgrade rafts/boats, explore islands, fight enemies and sea threats, manage hunger/oxygen/health, and aim to survive as long as possible (ideally 100 days) while getting rich.
Classes function as character loadouts or “units” that provide starter tools, stats buffs, and abilities/perks (often with leveling). They are unlocked with Pearls earned from chests, quests, etc. The game emphasizes survival, exploration, combat, crafting, and resource management rather than pure tower defense, though combat against waves/enemies is key.
What a Tier List Represents
A tier list ranks classes based on overall power, utility, versatility, survivability, damage output, and effectiveness across early/mid/late game, solo or group play. Higher tiers (S+) excel in meta strategies, deal high damage, provide strong buffs, or offer unique advantages that make runs easier and more successful. Lower tiers are more situational or starter options with limited impact. Rankings can shift slightly with updates, but this reflects current community/meta consensus (e.g., from July 2026 sources).
Overall Tier List Summary

| S+ | Fire Mage, Ice Mage, Ancient Squid, Alien Overlord |

| B | Zookeeper, Builderman, Chef, Medic, Night, Merchant, Harpooner (and similar mid-tier) |

Detailed Tier-by-Tier Breakdown
S+ Tier
These are the most powerful, meta-defining classes capable of dominating in almost any situation, especially late-game combat and high-damage runs. They offer exceptional damage, mobility, or versatility that trivializes threats.
| Character | Description / Power-Ups / Information |
|---|---|
| Fire Mage | Magma Staff starter; massive +Magic Damage (scaling to very high levels). Melts enemies fastest; self-sufficient due to raw DPS. Top meta pick but expensive. |
| Ice Mage | Ice Staff; strong Magic Damage + sprint speed. Excellent AoE/single-target control and mobility side-grade to Fire Mage. |
| Ancient Squid | Squid Laser Gun; sprint speed, health, and powerful non-overheating laser at max level. Highly versatile for combat/exploration. |
| Alien Overlord | Ray Gun + UFO Ship; high ranged damage, fast exploration/mobility via UFO. Strong all-rounder for fast map control. |
S Tier
Excellent classes that are near-meta. They shine in specific roles (melee, ranged, tank, mobility) and perform reliably across most scenarios with good investment.
| Character | Description / Power-Ups / Information |
|---|---|
| Hero | Holy Sword; health/hunger buffs + healing on kills. Best early-game melee tank; strong survivability. |
| Knight | Claymore + armor (damage reduction); sprint/health/melee buffs. Top tank with great versatility and affordability. |
| Alien Warrior | Energy Sword + armor; melee damage and health/damage reduction. Strong durable melee DPS. |
| Pirate | Blunderbuss; high gun damage + boat speed/ammo. Excellent ranged with exploration utility. |
| Sharpshooter | Flintlock; gun damage + reload speed/ammo. Top pure ranged damage dealer. |
| Battle Bunny | Egg Grenades + multi-jump/sprint; explosive damage. Best mobility/outplay potential (high skill ceiling). |
| Raider | Dual Pistols; ammo sustain on kills + sprint. Reliable ranged with near-infinite ammo potential. |
A Tier
Strong, reliable classes good for progression, farming, or specific strategies. They offer solid utility but may lack the raw power or versatility of higher tiers.
| Character | Description / Power-Ups / Information |
|---|---|
| Treasure Hunter | Doubloons/sack slots; looting specialist. Best for resource/wealth runs but weak in solo combat. |
| Millionaire | Luxury Yacht + health/doubloons/boat speed. Great hybrid for exploration and tankiness. |
| Swordsman | Machete; high melee damage/health. Cheap strong early-mid melee option. |
| Olympian | Sprint/health/double jump. Excellent mobility and tankiness; universally useful. |
| Soldier | Assault Rifle + armor/sprint/ammo. Solid all-rounder ranged with durability. |
| Cowboy | Revolver; gun damage/health. Good cheap ranged but ammo-limited. |
B Tier
Decent mid-tier options with niche strengths (support, crafting, companions). Useful in teams or for specific playstyles but generally outclassed in raw power.
| Character | Description / Power-Ups / Information |
|---|---|
| Zookeeper | Companion power boosts. Strong with good pets but reliant on them. |
| Builderman | Cheaper crafting + structure health. Team crafting specialist. |
| Chef | Food production/healing/hunger. Sustain support role. |
| Medic | Healing tools/regeneration. Key team support for longevity. |
| Night (Knight variant) | Armor/damage reduction/sprint. Tanky melee option. |

Basic/starter classes with minor utility. Best for new players learning mechanics or very early runs, but upgrade quickly for better performance. Low combat impact.
| Character | Description / Power-Ups / Information |
|---|---|
| Sailor | Boat speed/handling. Early exploration helper. |
| Survivor | Regeneration/oxygen/hunger. Beginner-friendly sustain. |
| Crewmate | Basic gun damage. Entry-level ranged. |
