Nautilus Shell

Nautilus Shells are obtained by fishing, killing drowned mobs, or trading with wandering traders. They are a rare and valuable item with no crafting recipe.

Nautilus Shells are used exclusively to craft conduits, which provide underwater breathing, night vision, and mining speed boosts when activated with prismarine blocks. Since conduits are essential for underwater exploration and base building, Nautilus Shells are a key resource for ocean-based gameplay.
