Guide:Bases

A base is needed in Terraria as it allows NPCs to spawn into your world. Early game players won't have many good blocks to build and decorate their bases, but by the midgame players should have access to better types of blocks. It is recommended that you use doors inside, for it to count as a home, but have some form of blocking doors or defending outside, such as dart traps or blocks wired with actuators to appear when you hit a switch.

Houses

 * See Houses.

A House is an enclosed area fitting certain requirements that will house an NPC, but as multiple Houses can be connected by sharing the same walls, floors, ceilings and Doors. The individual NPC "Houses" usually become rooms within a larger building. A single house must be 6 blocks high and 10 blocks wide for it to count as an actual house.

As the NPCs on Console and Mobile versions are vulnerable to enemies, this should generally be one of the most secure places in a base. Keeping the NPC rooms off of the ground floor will prevent deaths from Wraiths once hardmode is enabled. Some players may not bother since NPCs respawn fairly quickly. In the PC versions NPCs can defend themselves against weaker enemies from 1.3 but later game events and bosses won't be fazed so plan ahead.

One tactic to use is to build your houses facing each other, with Wood Platforms as doors. Then cover the space between the houses with an easily destroyed block like Dirt, Ash,or if one wouldn't mind the falling blocks, Sand, Silt or even Slush. Also. there is a glitch where if you put stairs (Hammer platforms) on either side of a door, you can go through the blocks, so you can just place wooden platforms inside the floor, where mobs cannot enter.

A good way to keep mobs away from your house if it is on the ground is to go on either side and build a T shaped doorway outside, So walking mobs can't jump it and flying mobs get caught under the top of the T.

Bedroom

 * See also Bed.



The player's own room within the larger structure should contain a Bed, which will serve as their spawn point. If the player has a Magic Mirror, this is where they will teleport to when using it. It is better to spawn and teleport to a safe and enclosed room in your home, rather than somewhere outside in the open. Another useful tip is to keep the Nurse near your spawn point, so you can heal when recovering from death.


 * USEFUL TIP: you can have multiple spawn points set up by building a base away from the original spawn point, using a bed as normal, but having at least a small portion of the structure made of active stone wall. With a flick of a switch, it's no longer a valid house, and thus resets the spawn point to the original point. Hitting the switch again makes it a valid structure again, without the need to reset the spawn point. If you have a lot of money, you can wire a small world up so that you can hit a switch at the original spawn point too. Great for quick travel to necessary places.

Note that as of version 1.2 of the game the Steampunker has Teleporters available for sale, reducing the need to tinker with spawn points.

Crafting area

 * See also: Guide:Crafting 101.

Having a centralized crafting area can keep things more organized. These items altogether probably warrant their own room. Keeping a Chest or two next to your crafting area is an efficient way to store and access your crafting materials quickly.The crafting stations are:
 * Any Workbench
 * an Anvil or a Mythril Anvil or Orichalcum Anvil
 * Furnace, Hellforge, Titanium Forge, or Adamantite Forge
 * Placed Bottle, Alchemy Station or Alchemy Table and an Imbuing Station
 * Loom
 * Cooking Pot
 * Sawmill
 * Demon Altar/Crimson Altar (Cannot be moved or placed. House must be built around one of them. See picture)
 * Water (For crafting Bottled Water)
 * Honey (For crafting Bottled Honey)
 * Tinkerer's Workshop
 * Any Bookcase
 * Ancient Manipulator
 * Autohammer
 * Heavy Work Bench
 * Extractinator

There are also specialized crafting stations to make different types of items out of specific materials. These include:
 * Blend-O-Matic
 * Meat Grinder
 * Crystal Ball
 * Dye Vat

Note that putting all crafting stations together has the downside of forcing the player to scroll through every potential crafting option to find the one that they need. Arranging the stations in a logical manner around your home may end up being more convenient. (Pre 1.2)
 * Bone Welder
 * Glass Kiln
 * Honey Dispenser
 * Ice Machine
 * Living Loom
 * Sky Mill
 * Solidifier
 * Steampunk Boiler
 * Flesh Cloning Vat
 * Lihzahrd Furnace


 * Clicking on the icon that looks like a hammer with dots under it next to the crafting list will open the Crafting Window which lets you see all crafting options available. Clicking on the desired item to craft will select that item on the crafting list.

Storage
Storage is achieved through the use of Storage items like the Chest. Storage is necessary given the amount of items that can be collected. Using a variety of different containers can make a storage area more navigable, as can using decorative items, statues, signs, or renaming the containers. Usually players put similar types of items into the same chest(s). Some players may even wish to integrate their crafting area to provide a sort of structure.

Players may wish to organize their storage items the same way between all worlds so that they don't have to remember a new pattern for each one.

One feature added, is when you open up a chest there is a quick stack option that will allow all inventory that you carry to be added with likewise inventory of the chest. Note: As of 1.3, if a stack of identical items reaches maximum stack they will now continue to be added to the chest in a separate stack.

Another feature added is that you can rename all chests so you can see it when you hover with your mouse over the chest. (PC only)

It may be useful to keep associated items in mini-bases near their biomes, e.g. make a base close to the jungle, and store things you would get in the jungle in it. These mini-bases might include useful teleportation rooms, to quickly gain access to the biome from home and to that storage area.

Garden

 * See also: Guide:Gardening.

A dedicated garden can keep the player supplied with a steady variety of potions. Mushrooms and herbs can both be systematically produced and gathered, providing a considerable power boost to the prepared player.

Roof Access
Often a minor consideration, but a player that spends a fair amount of time in a large base has a good chance that Fallen Stars will accumulate on the roof overnight. The player may consider adding access to the flat roof along its length to grab these. If there is only 1 tile between select items and the player, the player may jump and hit the ceiling and the item will go through the wall and into the players inventory.

Teleporter Room
A Teleporter Room may be useful for late-game players who need to get to far away outposts quickly. Setting one up, however, will take a long time and will be very expensive to build considering the current price of Wire and the distances that need to be covered with wire to reach places like the Dungeon and The Underworld. Hoiks make it possible to build a teleporter room where the player can enter a code and it will automatically teleport them there, without need to run along a long line of teleporters. See http://forums.terraria.org/index.php?threads/guide-how-to-build-a-hoiktronics-based-teleporter-hub-updated-version.15368/ for how to build.

Outposts
There are two basic categories of outposts. You can build an outpost upon being ready to enter a particular biome for a first time, allowing rapid transit in and out. These outposts are minimalistic, usually just consisting of a bedroom and several chests. You can also build an outpost in a biome once you have already progressed past that point, to farm it for rare resources. These are typically more extensive, with large portions of the biome itself reconstructed to suit the player's needs. The entire creation of an outpost has been radically improved with the introduction of the Teleporter in 1.2, as players can now get to any outpost virtually instantly.

The Underworld
The Underworld has valuable resources not found elsewhere, such as Hellstone and Fireblossoms, so having an outpost there is valuable once you have progressed to that point. Players often construct Hellevators to provide easy access to the Underworld. Demons can be farmed for the Demon Scythe, Fire Imps can be farmed for the Plumber's Hat, And the Voodoo Demon can be farmed for Guide Voodoo Doll [used for fighting the Wall of Flesh (Many items in Hardmode need Emblems dropped by this boss, so it's useful to farm Dolls)]. Creating an open area with wooden platforms can help facilitate the rapid farming of these creatures. It also is the place where the Wall of Flesh is fought, granting the player Hardmode.

Jungle
Placing an outpost in the Jungle allows the farming of a variety of resources. Piranhas will drop the Robot Hat, the underground variants can provide Vines, Jungle Spores, and Stingers. Players may also gather Jungle Rose, Nature's Gift, and simple Jungle Grass Seed. It can also provide quick and easy access to the Jungle Temple, which is a valuable place in Hardmode. An artificial jungle may also be created for a more controlled environment. Warning: If not powerful or in a team, stay out.

Desert
Desert biomes allow the farming of Waterleaf, Cactus and Antlion Mandible. Hallowed and corrupt variants allow farming for the Dao of Pow. A large flat area is ideal. For non-mob farming purposes, one block thick sand is enough.

Floating Island
Farming Harpies for feathers and Wyvern for Soul of Flight necessitates an accessible platform high in the sky. Players can also use an existing Floating Island for this purpose. An arena-style area with wooden platforms makes the fights easier.On top of each floating island is a house containing skyware chests and furniture in which you can shelter from Harpies.

Snow Biome
Building here, on the surface, is not highly recommended due to lack of anything interesting. However, there are many useful drops to farm underground including Frozen Turtle Shell and Ice Chest Mimics. Also, players may wish to build here anyway to make use of their Candy Cane Blocks and Ice Bricks. Snow is also uncorruptable [but ice blocks are] so if a player seeks sanctuary from the corruption, they may want to build in a snow biome.

Ocean
An ocean outpost is one of the more useful options, good for farming valuable Shark Fin and Coral. The easiest method is to simply build on the coast. Dedicated players with good swimming equipment can build an underwater base by using pumps to remove the water from their structures. Another way to drain a base is to build walls and a roof, then dig a small pit beneath the base, one row of blocks larger than the building. Once the water is in the pit, cover it with any tile. Players may also wish to place underwater light sources.

If you want to do something different, try digging a mini-mineshaft just until you bypass all the sand. Dig a horizontal tunnel 2 tiles long and dig up 3 blocks. (Be careful of the sand... Remember it is affected by gravity. Once it gets in your tunnel you can't get it out without flooding the whole base.) Once you reach this point dig 2-3 blocks across (horizontally) from the highest point of your tunnel (3-4 blocks high, if you're doing it right) Then dig a mineshaft down. If you did it right you can now make a DRY underground/ underwater base.

Another method, for quick trips to the ocean to collect loot from monsters and chests, is to extend a platform out over the ocean and then use ropes to reach the bottom of the ocean, then travel up and down it to avoid drowning safely, and possibly stylize your platform as a pirate ship, if you so will.There is also a crystal cavern under most oceans that is good for hard mode.

Corruption
A base in the corruption allows the player to farm Vile Mushroom and Rotten Chunk, as well as providing a reliable location to summon the Eater of Worlds. The more valuable treasures lay deep underground; Cursed Flame and Soul of Night are both quite valuable. To capitalize on this, players may wish to clear out an area underground and connect it to their Corruption base, for easier farming of these materials.

Crimson
A base in the crimson allows the player to farm Vertebrae, Vicious Mushrooms, and Meat Grinder, as well as providing a reliable location to summon the Brain of Cthulhu. The more valuable treasures lay deep underground; Ichor and Soul of Night are both quite valuable, along with useful Vitamins. To capitalize on this, players may wish to clear out an area underground and connect it to their Crimson base.

Hallow
A base in the hallow can provide Pixie Dust and Unicorn Horns. A large, flat area is best for gathering these. Underground hallow can provide Crystal Shard and Soul of Light. Several long, straight tunnels make gathering Crystal Shards faster. Players wishing to make a base that melds with the environment may want to build with Pearlstone.

Base Defense

 * See also Guide: Base Defense, and Guide:Defending against events.

Player-made structures do not come with guarantees against the local fauna or events. With this in mind, it is a good idea to prepare defenses against a variety of possible scenarios. How much effort to be invested depends entirely on the player; for example, having monsters wandering around plant farms may be no big deal but many would prefer their NPC areas to be protected. If you already built a base on the ground, and don't want to move, move your chest room within your town of NPCs, this will prevent monster spawns. Also, place Peace Candles around your house if it is big to minimize spawns.

Skybridge
A Meteorite crash can gouge out a huge chunk of terrain and this can be catastrophic if a direct hit occurred on a base. To protect against this a Skybridge can be built over the top of the structure to intercept the possible paths of falling meteors. When a meteorite does crash into this bridge it will change the blocks in the affected sections to Meteorite and create a hole in your skybridge. It is advisable to patrol the skybridge occasionally to check whether it needs repairing. (This is also a good way to "farm" meteorites in a controlled way). Skybridges can also be used for farming Fallen Stars, or to stop them from falling on your house. As of 1.3.1, when Conveyor Belts were added, it is now possible to make an AFK Fallen Star farm, where Fallen Stars automatically are carried to the player. Hooks can also be utilised for this purpose.

Tower Base
A versatile and effective strategy is to build a floating tower.This would be constructed with a wide basement area for storage, a wide first floor as a generic crafting station, and additional floors above which would be 5 blocks tall and 12 blocks wide. With an area of 60, it allows NPCs to move in. It is best to build 18 rooms for NPC's as soon as possible and set your spawn point in the storage/basement floor, as you can restock items upon respawn. The tower should float at least 3-6 blocks above the rest of the terrain to make sure it can not be run down by blood moons, goblin invasions, or other events, infected by corruption or infiltrated by wraiths in Hardmode. This allows quick access to all your items and your NPCs all at once. Construction of other specialized homes (e.g. a house in the Jungle for the Witch Doctor or a Overground Mushroom Biome for the Truffle are completely fine, but building a temporary tower for all the NPCs helps get more merchants sooner which proves useful in end-game (Pre-Hardmode) and beyond.

Floating Base
Structures do not actually have to rest on surfaces, gravity notwithstanding. Once built, the terrain surrounding the base can be dug out to create a virtual moat around it, preventing easy access by most monsters. The Guide: Base Defense article goes into this in more detail. To build a floating base, get a stack of dirt or any other material not affected by gravity, and build straight up. or, if you are late-game, use an ice rod after flying upwards. You want to build high enough off the ground so that no enemies can get to you, but low enough that Wyverns don't spawn late-game. When you are high enough, start building wood in a horizontal line. Place rope on one of the sides so that you can get down. Destroy the line of dirt or other blocks up to your flat line in the air. Now, just go back up your rope and start building in your sky city! This is best done in large worlds, since you can get pretty high off the ground without summoning Wyvern.

Actuator Door
By using actuators and Grey, Brown, Blue or Lihzahrd Pressure Plates, you can create a player only door that doesn't even require you to use your mouse. Set-up the door as you would an active stone/actuator door and because Grey, Brown, Blue or Lihzahrd pressure plates can only be activated by the player, no mobs are able to enter (or escape). You can provide defense using super dart traps and spiky ball traps after you gain access to the Lihzahrd Temple, you do not require the Picksaw to be able to mine these traps. As of 1.3.1, where Sensors were added, it is now possible to link the sensor (Player above) to an actuated door, allowing the player to pass by a door without having to step on a pressure plate.
