#Conduit

Nautilus shells are rare items that you can get in three different ways in Minecraft. One of them is fishing since the nautilus shells are part of the treasure fishing loot. You can also kill drowned that hold nautilus shells in their off-hand, and you are guaranteed to get it. Finally, wandering traders can sometimes sell nautilus shell for five emeralds each. You can use eight nautilus shells together with a heart of the sea to craft a conduit.
