A nautilus shell might look like a decorative ocean souvenir, but it has a practical role in an underwater project. Pair eight shells with one heart of the sea to craft a conduit. Minecraft's official conduit guide confirms the recipe.
What is a nautilus shell used for?
Its main use is the conduit recipe. Put the heart of the sea in the center of a crafting grid and place a shell in each of the eight surrounding slots. A crafted conduit still needs an underwater frame to activate; crafting it is the start of the project, not the whole setup. The official conduit article explains the effect and why underwater builders value it.
| Keep this | Why |
|---|---|
| One shell | Counts toward the eight-shell recipe |
| Eight shells | Enough for one conduit, if you have a heart of the sea |
| Heart of the sea | The center ingredient for the conduit |
How can you get a shell?
Minecraft's nautilus shell feature describes three established routes: rare fishing finds, wandering-trader offers, and drowned that carry a shell. Those routes are useful when you want to collect shells without planning around a particular newer mob.
A version note matters here. The 2023 feature says there were no nautilus mobs in the game at that time. Minecraft later added nautilus mobs. The Java 1.21.11 release notes say they can drop a shell when killed, with the chance increasing with Looting. Older articles that claim no nautilus exists describe an earlier version, not every current world.
Which route should you choose?
If you are already fishing, keep a shell as a pleasant bonus. A wandering trader gives you a more direct exchange when the offer appears. Drowned are another established source. In a world with the newer nautilus update, the mob is an additional route. The best choice depends on your version, equipment, and what you enjoy doing; none of these routes guarantees a quick eight shells.
What should you do after collecting eight?
Find a heart of the sea, usually through buried treasure, then craft the conduit. Before carrying everything to a remote ocean build, read Minecraft's heart of the sea guide and conduit feature. Plan the underwater frame and keep extra materials for the trip.
