100 Days at Sea Armor Guide – All Armor Sets & Best Armor

Armor is one of the most important parts of surviving in 100 Days at Sea. Whether you’re fighting bosses, defending against raids, or exploring dangerous islands, having better armor can significantly reduce the damage you take.

This guide covers all the armor mentioned in the game, how armor works, where to find it, and which sets are worth using.

In 100 Days at Sea, you can equip:

• 1 Chest Armor

• 1 Leg Armor

Equipping both pieces from the same set gives you the complete benefits of that armor set.

Be careful when replacing armor. Picking up a new armor piece automatically drops the piece you’re currently wearing, so make sure you actually want to replace your equipment before grabbing another piece.

Most armor can be found inside chests around the world.

The best places to search for armor are container chests inside structures such as:

• Container Shelters

• Makeshift Buildings

• Outposts

These structures can appear on Oil Rigs and Pirate Stronghold Islands. Container chests have a better chance of containing armor than regular chests, making them a good target when you’re looking for upgrades.

Wooden armor is one of the earliest armor sets you’ll encounter.

• Wooden Chest: 5% damage reduction

• Wooden Legs: 5% damage reduction

While the protection is modest, wooden armor is still much better than going without armor during the early stages of the game.

Bronze armor provides a noticeable improvement over wooden equipment.

• Bronze Chest: 8% damage reduction

• Bronze Legs: 8% damage reduction

It’s a solid early-game upgrade if you find it while exploring.

Iron armor increases your protection further.

• Iron Chest: 12% damage reduction

• Iron Legs: 12% damage reduction

Once you start exploring more dangerous areas, upgrading from bronze to iron can make fights considerably easier.

Steel armor offers another defensive upgrade.

• Steel Chest: 15% damage reduction

• Steel Legs: 15% damage reduction

It’s a strong general-purpose armor set and a good choice until you obtain some of the more specialized equipment.

Diamond armor is one of the strongest standard armor sets available from chests.

• Diamond Chest: 20% damage reduction

• Diamond Legs: 20% damage reduction

With both pieces equipped, diamond armor provides excellent protection for difficult fights, dangerous islands, and late-game exploration.

If you’re looking for a reliable all-around armor set, Diamond Armor is one of the best choices.

Gold armor focuses on utility rather than maximum defense.

The Gold Chest provides:

• 10% damage reduction

• 10% increased Don gains

This makes it particularly useful when you’re farming currency. If you’re focused on making money rather than maximizing survivability, gold armor can be a valuable option.

Warrior armor provides a mixture of offense and defense.

The Warrior Chest gives:

• 10% damage reduction

• 10% increased melee damage

This makes it a good choice for players who rely heavily on melee weapons and want additional damage without completely sacrificing defense.

The Alien Warrior class starts with Alien Chest and Alien Legs, and these pieces can also be obtained from the Dynamite Alien Island.

The complete set provides:

• 15% damage reduction

• 15% increased maximum HP

The additional health makes Alien Warrior Armor particularly useful for players who want more survivability rather than simply stacking damage reduction.

Night Armor is one of the strongest defensive options mentioned in the guide.

It provides:

• 30% damage reduction

That makes it an excellent choice for players who want to tank powerful enemies and survive dangerous encounters.

If your main priority is staying alive, Night Armor is arguably the best defensive set from the listed armor.

The Soldier class unlocks Military Armor at Level 2.

The exact effects of Military Armor are not revealed in the provided information, so it isn’t possible to accurately rank its stats yet.

However, getting access to stronger armor is still important because additional protection helps you survive raids, bosses, and dangerous exploration areas.

If you’re deciding what armor to prioritize, here’s a simple ranking based on the bonuses provided:

Best Overall Defense: Night Armor Best Standard Armor: Diamond Armor Best for Extra HP: Alien Warrior Armor Best for Money Farming: Gold Armor Best for Melee Builds: Warrior Armor Best Early Game: Bronze → Iron → Steel Best Beginner Upgrade: Wooden Armor

A simple progression path is:

Wooden → Bronze → Iron → Steel → Diamond

As you explore more islands and find better chests, gradually replace your weaker armor with stronger pieces.

For specialized builds, you can switch to Gold for currency farming, Warrior for melee damage, Alien Warrior for additional HP, or Night Armor when maximum defense is your priority.

Always wear armor when possible. Even the weakest armor is better than having no protection, especially when you’re exploring dangerous islands or fighting bosses.

When searching for upgrades, prioritize container chests inside structures on Oil Rigs and Pirate Stronghold Islands. Once you obtain stronger equipment, replace your weaker pieces carefully because picking up new armor automatically drops what you’re currently wearing.

For pure survivability, Night Armor stands out with its 30% damage reduction, while Diamond Armor is an excellent standard option with 20% damage reduction.
