Go to hell

Inspired by that one scene from the 2005 Constantine movie where you gotta get a cat and sit in a cauldron of holy water to go to hell. You can get holy water from a librarian trade and i mean also have to tame a cat. Once there you have (by default you can change via gamerule) 10 minutes in the nether, after which you will be returned to the cauldron. On return you will have "Soul fatigue" and wont be able to return to the nether again for (again by default) 30 minutes.
