这个中等难度的地形是比较特殊的：每当打碎一个暗影球或者恶魔心脏的时候，都会有一定概率在游戏里第二天生成一个陨石坑，并且提示玩家“一个陨石坠落了！”。陨石会在地面弄出一个大坑，并且将周围的一些物块变成陨铁。陨石会在玩家未装备诸如黑曜石头骨、黑曜石护盾或 黑曜石头盔 的时候对玩家造成灼伤。陨铁只能使用金镐及以上的工具挖掘，而更低等级的镐子无法破坏陨铁。 炸药可以起到可观的作用。当一个区域里有50格或以上的陨铁 时， Meteor Heads 会生成。 这些怪物会飞行并穿透固体物块给玩家造成较大的伤害（有几率造成燃烧debuff）。有一个好办法是使用 vilethorn, 因为一次攻击可以穿透多个 Meteor head s.经历危险之后， 陨铁套装便成为了新手进阶的一大步。
The 浮空岛 are some of the smallest biomes that the player will come across. Due to their location in the sky they are also one of the harder biomes to reach. Finding them is not an easy task, but can be accomplished by using a 枪 和 陨铁弹 或者 水箭魔法书 spell, both of which bounce off objects. Once found, simply build a tower or use a 反重力药剂 to float up to it. The items on Floating Islands are very useful, and will serve most players well even in the end game and since the 1.2 update they won't require Keys. The monsters that spawn here will be the same as the monsters as from the Forest biome, as well as Harpies (and 白龙 on 困难模式 ) When Hardmode is initiated, if a floating island is in line with the generation of hallow/corruption, the island will be converted to it. Although rare, Meteors can hit a floating island. As of the 1.2 update, Floating Islands contain a plethora of unique materials, including Clouds, Rainclouds and the House will be made of and contain Skyware items.
生命之树 are huge, thick trees that can be generated. Cutting the tree yields regular 木材. Some of those trees can be hollow and lead deep underground. There may be rooms containing Living Wood Chests with related loot inside, as well as 原木门, 原木椅, 原木桌 and other Living Wood furniture.
Spider Nests are rare mini-biomes that can be located underground, noted by the black background wall and the numerous webs filling the area. This biome will spawn 爬墙蜘蛛 when entered. The Cobwebs filling this area rapidly grow back, which is a unique feature of the biome. Spider Nests are the only location where one can find 蛛网箱子s and all unique treasures discovered therein.
A Biome found in the underground jungle, the Lihzahrd temple is an end-game biome that can be accessed with a key dropped by 世纪之花. Though a hard-mode level biome, the Temple can be entered at any time in a new world assuming the player has a key or a pickaxe strong enough to dig into the temple's bricks. Inside, one will find that immense danger awaits them, filled to the brim with spear and spike ball traps and dangerous 蜥蜴人 and flying serpent monsters. It is highly suggested to stay off the ground, as all traps are pressure plate activated. Chests found in this area will always contain Lihzahrd power cells, used to activate an altar at the end which summons the 太阳傀儡.
太空 is a layer appearing at the top of the world: ~950 feet and above, for large worlds. The sky is dark and stars are visible, even when the Sun is still up. Nothing much happens in 太空, though an exclusive background and music will be present.
