Minecraft wiki entry for Complete_main_adventure, associated text: Once the ender pearls and blaze powder have been obtained, combine the two to create eyes of ender. Bring at least 3 for locating an end portal, and 12 for filling the end portal, although most end portals already have 1 or 2 eyes of ender already in them. Launch an eye of ender to obtain a starting direction, and head that way. Launch another eye of ender once in a while to ensure the correct path is being followed, and that the nearest portal hasn't been passed. Ensure that the eyes are recollected at every given chance. When an eye heads into the ground, a portal has been located. At this point, one can attempt to find a cave that leads to the stronghold (true adventure style), or mine a spiral stair all the way down, so as to avoid digging straight down. Try to avoid falling into the pit of lava which is found under every portal.
