Iron Nautilus Armor

Iron Nautilus Armor is a protective piece of equipment designed to be worn by tamed nautiluses in Minecraft. When equipped on a nautilus, Iron Nautilus Armor reduces the amount of damage the creature takes, making it a practical choice for players who rely on their nautilus as a mount in dangerous aquatic environments. It sits at the fourth-highest tier of nautilus armor, offering more protection than copper nautilus armor but sitting below the stronger variants above it.

Iron Nautilus Armor cannot be crafted at a crafting table, nor is it available through villager trades. The only way to obtain it is by searching chests found in ocean-related structures such as Buried Treasure caches, Shipwrecks, and Ocean Ruins. The chance of finding Iron Nautilus Armor in any eligible chest is approximately 5%, so some exploration may be required before locating a piece.

To put Iron Nautilus Armor on a nautilus, a player can either hold the item and use it directly on a tamed nautilus, or place it into the dedicated armor slot through the nautilus's inventory interface. It is worth noting that baby nautiluses cannot wear any armor at all, since they are not rideable. Should the armor become unnecessary, it can be placed into a furnace and smelted down, yielding a single iron nugget as a byproduct.
