What is Nautilus Armor Minecraft and How Does It Work?
If you have spent any time exploring the deep oceans since the Mounts of Mayhem update launched, you already know that underwater combat can get incredibly chaotic. To help us navigate these aquatic depths, Mojang introduced the rideable Nautilus mob. However, just like our trusty horses on land, these aquatic mounts need protection. That is where nautilus armor minecraft comes into play.
Nautilus armor is a specialized item category designed to reduce the damage your aquatic companion takes from hostile mobs like Drowned, Guardians, or the Elder Guardian. It works identically to horse armor but is tailored specifically for the Nautilus and the Zombie Nautilus.
One of the best design choices Mojang made with this feature is that Nautilus armor has absolutely no durability. Whether your mount is being pelted by trident-wielding Drowned or squeezed by laser beams, the armor will never break or vanish. You can read up on the core physics of this system in the official Nautilus Armor Mechanics page, and learn how to find the mounts themselves in the Nautilus Mob Guide.
Nautilus Armor Tiers and Protection Stats
When we look at the protection scaling for Nautilus armor, it follows a progression similar to player armor, but with a massive leap in protective power at the higher tiers. Having a high-tier set ensures your mount can survive even the deepest ocean monument raids.
Copper, Iron, and Golden Nautilus Armor Minecraft Variants
The lower three tiers of Nautilus armor provide basic to moderate protection, but they also come with unique survival mechanics:
- Copper Nautilus Armor: This is the entry-level tier. It provides 4 armor points and no armor toughness. In Java Edition, it has a 10.8% chance of appearing in Buried Treasure, Shipwreck, and Ocean Ruins chests, while Bedrock Edition players have a 9% drop rate in Ocean Ruins. If you find yourself with an excess of these, you can easily smelt them down in a blast furnace to get copper nuggets. For more details on its technical IDs, check out the Copper Nautilus Armor Guide.
- Iron Nautilus Armor: Offering 5 armor points, the iron variant is a solid step up. It has a 5.4% drop rate in underwater loot chests and can also be smelted down into iron nuggets.
- Golden Nautilus Armor: Providing 7 armor points, Golden Nautilus armor has a 2.7% chance to spawn in loot chests. It has a brilliant secondary use: Piglins are incredibly attracted to it. If a Piglin spots you holding it or sees it on the ground, they will run over to pick it up, distracting them and granting you the “Oooh, shiny!” achievement. Like the others, it can be smelted into gold nuggets.
Diamond and Netherite Nautilus Armor Minecraft Variants
For players who demand the absolute best protection for their deep-sea expeditions, the top two tiers are where you want to focus your efforts.
- Diamond Nautilus Armor: This tier provides a hefty 11 armor points and 2 armor toughness. However, getting your hands on it is a true test of patience. Diamond Nautilus Armor has a mere 1.1% chance of appearing in loot chests in Java Edition and an even lower 0.9% in Bedrock Edition, officially making it the rarest chest loot in Minecraft! You can read more about its extreme rarity on the Diamond Nautilus Armor Details page.
- Netherite Nautilus Armor: This is the undisputed king of aquatic defense. It boasts an incredible 19 armor points, 3 armor toughness, and 1 knockback resistance (which translates to a 10% reduction in knockback). It cannot be found in any loot chests; it must be manually upgraded from the Diamond tier. You can view its full technical profile on the Netherite Nautilus Armor Details page.
How to Obtain and Upgrade Nautilus Armor
Because you cannot craft Copper, Iron, Gold, or Diamond Nautilus armor from raw resources, finding them requires some serious underwater archaeology.
We recommend targeting three primary structures during your search:
- Shipwrecks: Check the supply, treasure, and map chests.
- Ocean Ruins: Both big and small ruins hold chests buried under gravel and sand.
- Buried Treasure: Always follow Explorer Maps to find these, as they offer the highest overall yield for rare armor drops.
For a complete breakdown of structure coordinate maps and drop tables, refer to the How to Get Nautilus Armor guide.
Upgrading to Netherite Nautilus Armor
Once you are lucky enough to secure a Diamond Nautilus Armor set, you can upgrade it to the final Netherite tier.
To complete the upgrade, you will need to use a Smithing Table. The recipe requires:
- 1x Netherite Upgrade Smithing Template
- 1x Diamond Nautilus Armor
- 1x Netherite Ingot
Simply place the template in the first slot, the Diamond armor in the middle slot, and the Netherite ingot in the final slot to forge your Netherite Nautilus Armor. You can double-check the visual UI steps via the Netherite Upgrade Recipe.
How to Equip, Remove, and Enchant Nautilus Armor
Before you can dress your Nautilus in its shiny new protective gear, you must earn its trust.
- Taming: Locate an adult Nautilus and feed it buckets of pufferfish until hearts appear.
- Equipping: Hold your chosen Nautilus armor in your hand, walk up to your tamed adult Nautilus, and right-click (or press the “use” button on your console/mobile device). You will hear a satisfying metal clink as the armor snaps onto its shell.
- Removal: If you want to swap out tiers or store your armor, simply equip a pair of shears and right-click the armored Nautilus. The armor will pop off as an item, leaving your mount safe and sound.
- Enchanting: In standard Survival mode, Nautilus armor cannot be enchanted. However, if you are playing in Creative mode or have cheats enabled, you can use an anvil to combine the armor with enchanted books. Useful options include Thorns, Protection, and various environmental curses.
Frequently Asked Questions About Nautilus Armor
Can you craft Nautilus Armor in Survival mode?
No. You cannot craft Copper, Iron, Gold, or Diamond Nautilus armor using a standard crafting table. These items must be found as loot in underwater structures. The only exception is Netherite Nautilus Armor, which is obtained by upgrading a pre-existing Diamond set at a Smithing Table.
What happens when Piglins see Golden Nautilus Armor?
Piglins are highly attracted to the Golden variant. If you drop it near them, they will abandon their hostile state to pick it up and inspect it, giving you a perfect opportunity to escape or launch a surprise attack.
Can baby Nautiluses wear armor?
No. Baby Nautiluses are far too small to support the weight of heavy metal plating. You must wait for them to grow into full adults before you can equip any armor variants on them.
Conclusion
Equipping your aquatic mounts with the right gear is the absolute best way to ensure your underwater survival. Whether you are rocking the easily obtainable Copper tier or risking it all to hunt down the incredibly rare Diamond variant to upgrade to Netherite, nautilus armor minecraft adds a fantastic layer of depth to deep-sea exploration.
