All 16 Armor in 100 Days At Sea

Armor changes how much incoming damage reaches you, and some chest pieces also boost max HP, melee damage, or Doubloons. Your best pick depends on whether the next trip needs pure protection, a combat boost, or a little more treasure for the trouble.

Choosing chest armor

Knight Armor has the highest confirmed damage reduction, but it is locked to the Knight class. Diamond Chest is the strongest confirmed chest-loot option for pure protection, while Alien Chest trades some reduction for extra max HP.

Gold Chest and Warrior Chest are utility choices. Gold Chest helps with Doubloon gains, while Warrior Chest boosts melee damage. Pick the bonus that matches the job instead of treating every lower reduction value as an automatic downgrade.

Pairing leg armor

Choose leg armor separately from your chest piece. Diamond Legs leads the confirmed leg protection values, while Alien Legs mixes damage reduction with extra max HP. The material leg pieces offer a simple protection ladder when you want a straightforward upgrade from chest loot.

Getting class and island armor

Most material armor comes from opening chests. Knight Armor belongs to the Knight class, while Alien gear starts with Alien Warrior and can also be earned from the Dynamite Alien Island objective.

Military Armor unlocks at Soldier Level 2, but its effect is still unconfirmed. Its blank bonus is not a hidden zero, and it should not be ranked above or below confirmed gear until its effect is known.

Avoiding armor mistakes

Check the slot before comparing pieces. Chest armor competes with chest armor, and leg armor competes with leg armor.
Chest and leg effects work together, but do not add the displayed percentages into a promised total. The exact stacking formula is not documented.
Check class access before planning a build around Knight, Alien, or Military gear. A shiny plan is less useful when the locker says no.

FAQ

Can you equip chest and leg armor together in 100 Days At Sea?

Yes. You can wear one chest piece and one leg piece at the same time, and their effects work together.

Which chest armor has the highest confirmed damage reduction?

Knight Armor has the highest confirmed chest reduction at 30%, but only the Knight class can use it. Diamond Chest is the strongest confirmed chest-loot option at 20%.

What does Military Armor do?

Military Armor unlocks when the Soldier class reaches Level 2. Its effect is not confirmed yet, so it should not be treated as 0% reduction or given an assumed rank.

How do you get Alien armor?

Alien Chest and Alien Legs come with the Alien Warrior class. They can also be earned by completing the Dynamite Alien Island objective and claiming its armor reward.
