What is the heart of the sea in minecraft?

The Heart of the Sea is a rare item in Minecraft that was introduced in the 1.13 update, also known as the "Update Aquatic." It is primarily used to craft the conduit, which is a block that provides players with enhanced underwater vision and breathing abilities.

To obtain the Heart of the Sea, players can fish for it with a fishing rod or find it in buried treasure chests that are located in shipwrecks and underwater ruins. It cannot be obtained through crafting or smelting.

In addition to crafting the conduit, players can also use the Heart of the Sea to repair tridents. When combined with a damaged trident in an anvil, the Heart of the Sea will restore the trident's durability.

Overall, the Heart of the Sea is a valuable item that adds more depth to the underwater exploration in Minecraft.
