Minecraft wiki entry for Nether_hub, associated text: This will require a lot of time and blocks, but possibly one of the best protection against mobs and getting lost. Since you may come across mobs while doing this, it is recommended that you put all of your stuff in a chest except for a stone or iron pickaxe, a lot of ghast resistant blocks such as cobblestone, and a bunch of torches. That way, if you die, you don't lose anything valuable. The exact amount that you bring will be up to how confident you are that you will not die. If you are a beginner, only bring a couple stacks of blocks and torches, but if you are more advanced, you may want to fill up your inventory. You can always return to your base in the Overworld to get more supplies.
