Minecraft wiki entry for Speedrun, associated text: Think about the items you will need and gather these along the way as many resources can suddenly become rare when you need them. For instance, you will need gravel for flint, lava and water to make a nether portal, wool and wood for beds, and snowballs or arrows if you plan to use them to destroy the end crystals. Grab these items or make a note of their location as they can be hard to find when you need them.
