Environments

As of now, the world of Terraria consists of nine officially mentioned environment types. ==Forests== Forests are the only biome that can spawn small and large trees, which can be replanted using the acorns that are dropped by chopping them down. Natural caves may be found in this environment, although most are not more than 100 feet deep. Monsters: *Zombie (Night) *Demon Eye (Night) *Slime (Anytime) *Pinky (Anytime) ==Deserts== Large sandy areas that are occasionally generated. Nothing, however, is particularly special about them, as they are completely barren. They have the same monsters as forests. ==Underground== The underground consists of two layers: the dirt layer and the stone layer. Ores, pots, and chests can be found throughout. Water is a common sight anywhere underground and demon altars can be found within these layers, however it is a very rare occurrence. Lava becomes common near the bottom of the stone layer. Giant mushrooms have been seen as well. Monsters: *Giant Worm *Skeleton (stone layer) *Most Slimes, excluding Green Slimes *Mother Slime (stone layer) Chests may contain: *Bomb *Shuriken *Dynamite *Flippers *Lucky Horseshoe *Breathing Reed *Enchanted Boomerang *Hermes Boots *Cloud in a Bottle *Magic Mirror *Band of Regeneration *Angel Statue *Gold, Silver and Copper Coins Pots may contain: * Bomb * Shuriken * Torches * Arrows *Hooks *Silver and Copper Coins *Whoopie Cushion (Very Rare) ==Underground Jungle== The Underground Jungle is a very remote area of the world, residing deep underground. Like Dungeons, these areas have few dead ends; unlike Dungeons, however, they are covered in plants. They have special items that are found in Jungle Shrines, small buildings made of gold blocks that are spawned at random locations in the Underground Jungle. The Underground Jungle, a biome found underground (see the name), usually makes it's home from about 5% to 10% of the entire underground (might vary by map size). Much like dungeons, they stretch across the top of their horizontal location to the bottom of the map, stopping a bit above the Underworld biome. Other monsters common in the overworld and in the dirt-rock and rock-dirt layers can be found, but it has two unique monsters: the Hornet and the Man Eater. Underground Jungles are located in the opposite hemisphere (?) of the map from the Dungeon, and digging at the halfway point between the original spawn and the ocean will often place you into the Underground Jungle. The buffer between the Underground and the Underground Jungle is spottable by a random mixture of mud and stone/dirt. The Underground Jungle is a late-game enviroment, due to enemies being able to deal 30-40+ damage and its tricky navigation. {| align="right" border="1" cellpadding="1" cellspacing="1" style="width: 500px; " |Rarity |One per Map |- |Mobs |Hornet, Man Eaters |- |Recommened items |Gold Broadsword or higher, Lucky Horseshoe, Spells, 200+ HP |} ==Plants and Items==

Underground Jungles also make home to several unique plants, such as the Jungle Roses and Nature's Gift items. Both are used in tier 2 to 3 crafting, necessary in weapons such as the Thorn Chakrum and Blade of Grass. And it is necessary to make the tool Ivy Whip .The Underground Jungle can be found on the opposite side of the dungeon, sometimes under corruption chasms.

The Underground Jungle can also be helpful for making obsidian if there is a lava pool because of the fact that there are many water deposits so draining it onto the lava can be very effective. Underground Jungles are made almost entirely of mud, and this can sometimes reach to the surface, leaving large areas of almost entirely mud at the surface, which can be used to locate the Underground Jungle. Another way to help locate the underground jungle is to dig down to about 700-1200 depth and go laterally. The Underground Jungle is also on the opposite side of the spawn point as that world's dungeon. They are also very often found under or next to corruption. Monsters: *Man Eater *Hornet *Stone Layer enemies such as skeletons in the deeper areas of the jungle near areas with stone walls. *If the jungle is close to the underworld, you may also encounter fire imps. Jungle Shrines May Contain: *Nature's Gift *Feral Claws *Staff of Regrowth *Anklet of the Wind ==The Underworld== Main article: The Underworld A lava-filled, monster-infested hell located below the stone layer. This is, at the moment, the lowest layer in Terraria. It can be considered the most dangerous area, even for end-game players. The Underworld is the only place a player can obtain a Hellforge, which are located in tall, dilapidated buildings made of hellstone brick. The Underworld can be recognised by the lava veins in the wall. The Underworld is a late-game enviroment, and the use of Obsidian Skull is highly recommended, as well as healing potions and high damage dealing weapons. Monsters: *Bone Serpent *Fire Imp ==The Corruption== Main article: The Corruption The Corruption spawns higher-level monsters at all times of the day and should be avoided initially. Corruption is special because it will override nearby dirt blocks to spread, unless the dirt block has a sunflower on it. Chasms, Demon Altars, and Shadow Orbs can be found here. Corrupted areas can be cleared with Purification Powder. Monsters: *Devourer *Eater of Souls *Eater of Worlds (Spawnable Boss) Defeat of the Eye of Cthulhu is recommended before accessing this enviroment, as the use of Purification Powder from the Dryad is needed to gain full access to Shadow Orbs and some Demon Altars. ==Meteorite== After smashing a Shadow Orb, a Meteorite will crash into the planet. It is a small area, but should be avoided by lower-level players. The Meteorite itself is made of Meteorite ore, a high-level material that harms the player on contact (an Obsidian Skull is useful here as it protects from fire-block damage). Upon removing roughly 90% of the Meteorite, the local Meteor Head monsters will stop spawning on the edge of the screen. Note: It may take some time for the meteorite to spawn after the initial shattering of the Shadow Orb. Also, occasionally only one meteor zone will spawn at a time. It is currently unknown why. Note: It is not suggested that a player build skybridges to get across the map faster if they plan to use that map for harvesting Meteorite ore, as it may impact a bridge and yield minimal resources. With a one-cube-thick bridge, this will tend to yield only 8-10 ore, considerably less than a comparable hit on the ground. Recommended to be at a mid-game level to access this enviroment, but be warned touching meteorite is a moderate but quick damage dealer to unarmored players and Meteor Heads will often bombard and push the player into mentioned meteorite. Monsters: *Meteor Head ==Dungeons== Dungeons are enormous buildings found close to the edge of a generated world, spanning many layers deep. They're filled with treasure chests and unique items (water candles, books, chain lights, etc.), all of which are spread evenly (chests further down in the dungeon contain rewarding prizes such as different mana attacks, potions, dynamite, and handguns.) throughout the Dungeon (meaning that chests further down do not neccesarilly have better loot) On Small or Medium worlds, the bottom of the Dungeon will sometimes cut into the Underworld, providing a viable way to easily access the Underworld. To gain access, you must first defeat Skeletron, the guardian boss transformed from the Old Man near the enterance of the dungeon. Recommended to be at an mid-end-game level to access the Dungeon, as enemies in the Dungeon will deal up to 20+ damage even with armor, and efficient navigation requires a grappling hook or movement enhancing accessories. Some may attempt to make run throughs of the dungeon. This works out well if your a low level looking to score some rare items found in chests. If you have a grapling hook and a cloud in a bottle you can run from the skulls and loot one chest before they get to you and kill you. Note: Its not very efficient and its not recomended unless you have a spawn set close to the dungeon. Monsters: *Skeleton Head *Angry Bones *Burning Skull *Dark Caster *Skeletron (Guardian Boss) Chests may contain: *Aqua Scepter *Muramasa *Rocket Boots *Magic Missile *Angel Statue *Magic Mirror *Breathing Reed *Handgun *Blue Moon *Cobalt Shield *Band of Regeneration *Cloud in a Bottle *Hermes Boots * Feral Claws *Water Bolt (Also obtainable by breaking the pale blue book on a shelf. It does not have a regular coloration like the other books.) ==Floating Islands== Floating Islands are masses of land that appear in the sky. Just like in forests, you can find trees and grass growing over dirt blocks, with some stones and ores in the ground. They usually have a building made of ore bricks and a chest inside. In the Alpha version, the quality of the island can easily be identified by the type of brick the building is made of. The bricks show the quality of the treasure inside the chest, while the wall material represents the quality and quantity of the ore that can be found in or around the island. The monsters that spawn here are the same as the ones from the forest. The islands can be found at different levels of height, based on the size of the map selected. Note: Use a Depth Meter to find the floating islands as it is much easier to know where you are For small worlds the islands are located around 250-400 feet, and in some circumstances are very close to high hills. For normal/medium worlds it is around 400 to 500 feet, though can sometimes be found above and below that height. Your best bet for finding one is to go to 430 feet and move horizontally. For Large worlds they are located between 650-1200 feet. It is very difficult to find the islands on large maps because of the various heights, the best option is to get a map viewer that shows where the islands are. Another way to find floating islands is to craft meteorite bullets and shoot them into the air while traveling. Since metorite bullets richochet, you will be able to tell when there is an island above you, since the bullets will bounce off the islands and fall back down towards you. Link to a video demonstrating this technique can be seen here. If you spot any rare ores on the surface,(Such as Gold ore or silver ore, generally on the tops of hills.) there is a floating island very close. Simply use rocketboots to the sky, or pillar upwards and you should fund the floating island.

Chests may contain: *Lucky Horseshoe *Rocket Boots (very rare) *Shiny Red Balloon *Starfury
