The name says it, that if this is put in that lava will teleport you back but you can turn it off and on by using a command I made up : /togglelava and /togglefall . This is because before I was banned (a few more weeks until 1 year ago), I kept dying of fall damage but especially lava. This might help other players too, as some can't afford a town (200k in game currency) to build and place chests in or might not want to pay the taxes for towns as they might have good armour and might lose their items by death. the parkour I would like to have this idea in is balloon, flower and city. (not village) and on city, the floor below (the path and stuff) is out of bounds.
