A heart of the sea is a rare treasure with a clear purpose: it is the center of a conduit recipe. The result supports ambitious underwater projects.
How to find one
Follow a buried treasure map to its chest. The official Heart of the Sea feature describes the treasure-hunting route and explains why the item is worth seeking.
What do you make with it?
Place the heart in the middle of a crafting grid and surround it with eight nautilus shells to craft a conduit. Minecraft’s conduit guide documents the recipe. You still need to set up the conduit correctly underwater to benefit from it.
Should you keep it?
Yes. It is valuable for an underwater base or long ocean project, and the associated search is more involved than gathering ordinary building blocks. Store it safely until you have the shells and a build plan.
