Usage

Equipping

Iron nautilus armor can be equipped on a tamed nautilus by holding the nautilus armor and using the use button on a nautilus. It is also able to be equipped manually by putting it into the nautilus armor slot through mounting the nautilus and using its inventory control, or by sneaking and then using or pressing the "open inventory" button‌^{[Bedrock Edition only]}.

Baby nautiluses are unable to equip nautilus armor as they are not rideable.

Protection

When equipped, iron nautilus armor gives 5 () armor points.
