Companions are one of the most important progression systems in 100 Days At Sea. While most new players focus entirely on gathering resources, upgrading their raft, and crafting better equipment, companions quietly provide some of the strongest passive bonuses in the game. A good companion can make surviving longer much easier, especially once pirate attacks become more frequent and resources start becoming harder to maintain.
Companions are obtained from special chests purchased with Pearls. Every chest contains a different pool of companions, and each companion provides a unique benefit. Some improve combat performance, some increase survivability, and others help automate resource collection.
Choosing the right companion depends heavily on your playstyle. If you enjoy fighting pirates, damage-focused companions are extremely valuable. If you struggle with food management, hunger-reduction companions can save countless resources over a long play session. Meanwhile, gathering companions can steadily bring in materials and food without requiring any effort from you.
Below is a complete breakdown of every companion currently available in 100 Days At Sea and how useful they are during your survival journey.
Fisherman’s Chest
Cost: 40 Pearls
The Fisherman’s Chest is the cheapest companion chest available. Because of its low cost, this is usually the first chest most players will open. While the bonuses are smaller than those found in more expensive chests, many of these companions remain useful well into the late game.
Frog
Drop Chance: 25%
The Frog reduces hunger consumption by 5%.
At first glance, a 5% reduction may not sound particularly impressive, but food becomes one of the most important resources as your survival run gets longer. Every bit of hunger reduction helps stretch food supplies further.
For new players who frequently find themselves running out of food before reaching later days, the Frog provides consistent value throughout an entire run.
Turtle
Drop Chance: 25%
The Turtle increases your maximum health by 5%.
Extra health is always useful because it gives you more room for mistakes during pirate encounters and other dangerous situations. The Turtle is especially helpful for players still learning combat mechanics and enemy attack patterns.
The bonus is simple, but additional survivability is rarely a bad thing.
Crab
Drop Chance: 25%
The Crab increases gun damage by 5%.
Ranged combat becomes increasingly important during longer survival runs. The Crab allows firearms to hit slightly harder, helping eliminate threats faster while conserving ammunition.
Players who prefer using guns over melee weapons will find the Crab much more valuable than some of the defensive options.
Dolphin
Drop Chance: 13%
The Dolphin increases sprint speed by 7.5%.
Movement speed is one of those bonuses that feels small on paper but becomes noticeable almost immediately. Faster sprinting allows you to collect resources more efficiently, reposition during combat, and move around your raft more comfortably.
Many experienced players appreciate mobility bonuses because they improve nearly every aspect of gameplay.
Shark
Drop Chance: 13%
The Shark increases melee damage by 7.5%.
For players who spend most of their time fighting enemies with melee weapons, the Shark is one of the strongest companions available from the Fisherman’s Chest.
The damage increase helps shorten fights and reduces the amount of durability spent on weapons. If you’re using swords or other close-range equipment regularly, the Shark is an excellent companion to keep equipped.
Warrior Chest
Cost: 80 Pearls
The Warrior Chest focuses much more heavily on combat and utility. It costs twice as much as the Fisherman’s Chest but offers stronger bonuses and access to one of the best resource-generating companions in the game.
Snorf
Drop Chance: 32%
Snorf increases maximum health by 5%.
Functionally similar to the Turtle, Snorf provides additional durability during combat encounters. More health means greater survivability when facing large groups of enemies or powerful pirate attacks.
Defensive players will always appreciate having extra health available.
Cat
Drop Chance: 32%
The Cat increases sprint speed by 5%.
Although the movement bonus is slightly lower than the Dolphin’s, mobility remains extremely valuable throughout the game.
The Cat is especially useful for players who spend a lot of time gathering resources from the surrounding ocean and exploring points of interest.
Octopus
Drop Chance: 16%
The Octopus automatically brings materials every 120 seconds.
This is one of the most useful utility companions available early on.
Rather than directly increasing stats, the Octopus generates passive value over time. Every two minutes, it returns with materials that can be used for crafting, building, and maintaining your raft.
Long survival runs allow the Octopus to generate an impressive amount of resources without any effort from the player. Because of this, many experienced survivors consider it one of the best companions in the Warrior Chest.
Shark
Drop Chance: 16%
The Shark increases melee damage by 7.5%.
Just like its Fisherman’s Chest version, the Shark remains an excellent choice for aggressive players.
Melee-focused builds gain noticeable benefits from the increased damage output, making combat encounters quicker and safer.
Swordfish
Drop Chance: 5%
The Swordfish increases melee damage by 10%.
This is essentially an upgraded version of the Shark.
The drop chance is much lower, making it significantly harder to obtain, but the higher damage bonus makes it one of the strongest offensive companions available for melee players.
If you enjoy close-range combat, pulling a Swordfish from the Warrior Chest is a fantastic result.
Pirate Chest
Cost: 120 Pearls
The Pirate Chest introduces stronger combat bonuses alongside another resource-producing companion. Because it costs a substantial amount of Pearls, most players will begin opening these once they have already established a stable survival setup.
Whale
Drop Chance: 30%
The Whale increases maximum health by 7.5%.
Compared to the Turtle and Snorf, the Whale provides a larger survivability bonus.
This makes it one of the better defensive companions in the game, particularly for players tackling difficult late-game encounters.
Seagull
Drop Chance: 30%
The Seagull brings food every 120 seconds.
Food shortages can completely derail a survival run, especially during later days when resource management becomes more demanding.
The Seagull helps solve this issue by regularly delivering food. Over time, the amount of food generated can significantly reduce the pressure of constantly hunting for supplies.
For many players, the Seagull is one of the most practical companions available.
Parrot
Drop Chance: 30%
The Parrot increases gun damage by 7.5%.
Players who rely heavily on firearms will immediately notice the benefit of the Parrot.
The extra damage helps defeat enemies faster while improving overall combat efficiency. Gun-focused builds gain tremendous value from this companion.
Pirate Gunner
Drop Chance: 5%
The Pirate Gunner increases gun damage by 10%.
This companion is essentially the premium version of the Parrot.
Its low drop rate makes it difficult to acquire, but the larger damage boost makes it one of the strongest ranged combat companions currently available.
Dedicated firearm users should consider this a dream pull from the Pirate Chest.
Swordfish
Drop Chance: 5%
The Swordfish increases melee damage by 10%.
Just like the Warrior Chest version, the Swordfish remains one of the strongest melee companions in the game.
Any player focusing on close-range combat will be thrilled to unlock it.
Magma Chest
Cost: 120 Pearls
The Magma Chest contains a unique collection of companions that blend utility, survival, and combat bonuses. Several of these companions offer abilities unavailable anywhere else.
Dolphin
Drop Chance: 30%
The Dolphin increases sprint speed by 7.5%.
Movement speed remains useful from Day 1 all the way to Day 100.
Whether you’re gathering resources, avoiding enemies, or moving between crafting stations, faster movement always feels valuable.
Crow
Drop Chance: 30%
The Crow brings food every 120 seconds.
Functionally similar to the Seagull, the Crow helps maintain a steady food supply throughout a run.
Passive food generation becomes increasingly valuable as survival requirements grow more demanding.
Lava Snail
Drop Chance: 30%
The Lava Snail reduces hunger consumption by 7.5%.
Among all hunger-reduction companions currently available, the Lava Snail offers one of the strongest bonuses.
Players struggling with food management will find this companion incredibly helpful, especially during extended survival sessions.
Salamander
Drop Chance: 5%
The Salamander automatically grabs nearby food for you.
This companion offers a unique convenience-focused ability.
Instead of directly increasing stats, it helps collect nearby food items, reducing the amount of manual gathering required. While not as flashy as a damage companion, the quality-of-life improvement can be surprisingly useful.
Magma Golem
Drop Chance: 5%
The Magma Golem increases melee damage by 10%.
The Magma Golem is one of the strongest offensive companions available for melee builds.
Its bonus matches the Swordfish while offering a unique companion option from the Magma Chest. Players who enjoy charging directly into combat will get excellent value from this companion.
Companion Recommendations
After spending time with the available companion roster, a few companions stand out more than others depending on your goals.
For resource generation, the Octopus, Seagull, and Crow provide incredible long-term value because they continuously generate supplies without requiring player input.
For melee combat, the Swordfish and Magma Golem offer some of the highest damage bonuses currently available.
For ranged combat, the Pirate Gunner is arguably the strongest option thanks to its powerful gun damage increase.
For survivability, the Whale provides the largest health bonus among defensive companions.
For food efficiency, the Lava Snail is one of the best choices because reducing hunger consumption saves resources every single day.
If I were starting a fresh survival run today, I would personally prioritize obtaining an Octopus early on for passive materials, then transition into a Swordfish, Magma Golem, or Pirate Gunner depending on my preferred combat style. Resource generation helps establish a strong foundation early, while the stronger combat companions become more valuable once pirate attacks begin increasing in difficulty.
No matter which companion you obtain, every bonus contributes toward surviving all 100 days and uncovering the secrets hidden within the Bermuda Triangle. A well-chosen companion can often make the difference between barely surviving and comfortably thriving deep into a run.
