Armor is one of the best ways to improve your survivability in 100 Days at Sea. Whether you’re fighting bosses, defending your raft during night raids, or exploring dangerous islands, wearing the right armor can significantly reduce incoming damage. Some armor sets even provide extra bonuses like increased health, melee damage, or additional Doubloons. This guide covers how the armor system works, every Chest and Leg Armor available, their effects, and how to unlock them.
How Armor Works in 100 Days at Sea
The armor system is divided into two equipment slots:
- Chest Armor
- Leg Armor
You can equip one item in each slot at the same time. Most armor sets include both a chest piece and matching leg armor, allowing their bonuses to work together.
Before choosing an armor set, there are several mechanics worth knowing:
- Certain classes begin the game with exclusive armor.
- Equipping a new armor piece automatically drops your currently equipped one.
- Most armor pieces are obtained from loot chests found throughout the world.
- Container Chests generally have a higher chance of rewarding armor than regular chests.
- Wearing any armor is always better than having no protection at all.
Armor becomes especially valuable during difficult encounters, including boss battles, pirate raids, and late-game exploration where enemies deal much higher damage.
How to Get Armor
The majority of armor pieces can be found inside treasure chests while exploring islands. If you’re specifically hunting for better equipment, focus on Container Chests. These special chests are commonly found inside structures such as:
- Container Shelter
- Makeshift Building
- Outpost
These buildings can often be discovered on:
- Oil Rigs
- Pirate Stronghold Islands
Some armor sets are exclusive to certain classes or unique locations instead of random loot.

Armor plays a major role in surviving the dangerous world of 100 Days at Sea. Every set provides valuable protection, while certain pieces also improve health, melee damage, or Doubloon income. As you continue exploring islands and opening Container Chests, you’ll gradually replace weaker equipment with stronger armor that prepares you for bosses, pirate raids, and other late-game challenges. Always keep your armor upgraded, as the extra defense can make the difference between surviving an encounter and losing valuable progress.
