players can also play a special version of hardcore mode known as ultra hardcore mode, which is basically the same as hardcore mode except players do not naturally regenerate health. this mode can be accessed by creating a world in hardcore mode, enabling cheats using the "open to lan" option in the game menu, and using commands to turn off natural health regeneration. the only way the player can regenerate health in this game mode is by using potions, golden apples, suspicious stews, and beacons.
