Minecraft wiki entry for Things_not_to_do, associated text: However, if you are in the End and run out of equipment while fighting the Ender Dragon, or you don’t know your way back to the end portal, then you could jump into the void to get back to the overworld. Before you do this, though, you should put all of the items including armors in a Ender Chest so that you can access them in the overworld. Note that this makes you lose your Experience without the ability to recover it unless /gamerule keepInventory is set to true. It should be noted that the void can then be used to the player's advantage as a means to kill enemies.
