In Minecraft, a conduit is an underwater building that may be utilized to grant the player numerous underwater bonuses such as improved eyesight and water breathing. You’ll need eight nautilus shells and one heart of the sea to create a conduit. At the crafting table, arrange the nautilus shells in a square form and set the heart of the sea in the center slot. This will result in only one conduit.
