Spawn on an extreme mountains biome. After spawn you will see the huge overhangs, arching mountains, beautiful mountain tops. Let’s imagine building an base shelter under overhang terrain, that so cool. In this seed not only have an beautiful terrain, it also have secret dungeon. Quite of difficult to give an exact coordinates where the dungeons can be found, try to find it is an hard challenge for you. You will have good reward with iron ingots, food and wheat…include some diamond blocks in the dungeon, but careful with the creeper and zombies.
