Ghost

A ghost is a character's visual representation upon death while playing in Hardcore mode. Any items held on death will be dropped, and the character's maximum health will be reset to its default value. While in ghost form, a character cannot change or otherwise interact with the world, be harmed, or trigger events. They can only speak when in multiplayer. If they should log out, the character that became a ghost would no longer be listed in the character selection screen. Being a ghost can make it easier to find items because it allows you to pass through obstacles.
