An NPC is a friendly automated Non Player Character that provides a service to players.
Players can utilize NPCs by standing near them and using the ⚷ Open / Activate button on them. Most NPCs are vendors, selling items to players in exchange for coins, and can be sold items by a player in order to obtain coins. Some NPCs also perform other functions.
Most NPCs are "Town" NPCs, appearing after various milestones are achieved in game advancement (details below). They move into structures the player must generally build, known as houses, which are generally required for Town NPCs to remain available. Each NPC will need its own house.
Town NPCs that have moved into houses reduce enemy spawn rates in the area, an effect that increases the more of them are present. With four or more Town NPCs in close proximity, enemies generally stop spawning on or near the visible screen altogether. Players tend to utilize this effect by building large structures ("Towns" or "Bases") with several integrated houses, to serve as their safe haven. These reductions are usually overridden by Events like Blood Moons or Goblin Invasions, during which spawn rates return to normal, or are elevated, and enemies will once again attack players and NPCs in the area.
Town NPCs generally walk around during the day. They remain still in their assigned houses at night. NPCs have limited health and can take damage, and ultimately die from enemies, Traps, Lava, or by drowning in Water ( ); though they cannot be attacked directly by players (outside of special Voodoo Doll accessories or Rotten Eggs). They do not suffer from fall damage and their health regenerates over time.
If an NPC is killed, they will respawn after a delay, as long as a suitable vacant house is still available. If they have an inventory requirement to spawn (Merchant, Demolitionist, Arms Dealer, Dye Trader) they need to have the requirement met again in order to respawn.
Occasionally, NPCs sit in Chairs. They also randomly "talk" to each other, or to the player (shown as mouth movement and speech bubbles). Most NPCs also have an attack method, which they will use to defend themselves against enemies in the vicinity.
There are currently 23 / 22 / 21 / 19 Town NPCs, 7 / 6 of whom normally appear in Hardmode. An additional 3 / 2 / 1 NPCs can be encountered that don't move into houses.
Housing[edit | edit source]
Each Town NPC requires a suitable, vacant house. A house is a room enclosed by a frame of blocks, with user-placed background walls, along with a valid light source, flat surface item, and comfort item (see House § Furniture). Certain room dimensions are also required (see House for full details). Houses must not be located near Corruption or Crimson, and if those biomes spread too close to an occupied house, the NPC living there may move out from that house.
- On the Mobile version, there is no housing menu, however you can always see the banners, unlike the Desktop version, Console version, and . version
The Guide and Old Man are unique in that they always spawn upon creating a world. The Guide will usually move into the first house built. The Old Man does not move into a house, but rather remains near the Dungeon's entrance, and respawns the following day if killed (while Skeletron hasn't yet been defeated).
If a house occupied by an NPC is damaged in a way that makes it invalid, the NPC will move out and walk around the area until a suitable house is restored. If there are vacant houses available in the world, the NPC may move into one of them.
Buying and selling[edit | edit source]
Items can be bought simply by right-clicking an NPC and taking items from their inventory while their cost in coins is available in the player's inventory. (Or, on the Desktop version and Console version, when the required number of coins is in the players savings.) Holding the right mouse button on stackable items allows the player to buy the item in bulk. The buy speed increases the longer the right-click button is held.
All NPC vendors can also be used to sell unwanted or surplus items to gain coins. The unwanted item(s) must be in the player's inventory. Hovering over the item while the NPC's inventory screen is open will display its sell value. Items are always sold to vendors at one-fifth their purchase price. Not all items have a sell value (very common items such as Dirt or Wood have no value). To sell the item, move it into the NPC's inventory.
Sales to NPCs can be canceled while the NPC's inventory screen is still open: Sold items can be taken back in exchange for the amount they were sold for. This does not hold true for returning bought items, which must be sold back at their standard sell rate of one-fifth the purchase price.

Notes[edit | edit source]
- All NPCs have an attack damage stat of 10.
- NPCs will not (re-)spawn during an active Event or at night.
- An NPC takes about 2 minutes to spawn after another NPC has spawned or dawn passes.
- If valid housing is offscreen during spawning, the NPC will spawn directly into its house.
- NPCs will teleport home during the night if the NPC and their home are off-screen.
- Unlike chests and structures generated on world creation, bound NPCs spawn around the player's position on-the-fly, similar to enemy spawns. They are temporary, and can respawn elsewhere if missed (see NPC spawning).
- NPCs are known to "visit" other NPCs, talk, and play three rounds of rock, paper, scissors.
- NPCs aren't able to walk up stairs. The only NPC that can walk up stairs is the Traveling Merchant.
- NPCs can drown in water 2 tiles deep, whereas players require 3 tiles of water depth in order to drown.
- NPC vendors who have biome requirements to sell certain items need to be present in that biome in order to fulfill the requirement. It is not sufficient to have their home located in the specific biome.
- As the Mobile version currently has no housing interface, it is not possible to assign NPCs to certain houses, except through making any other possible houses (besides the desired one) not suitable for housing.
Tips[edit | edit source]
- Each time the Traveling Merchant spawns, he will have a random shop inventory. If the player leaves the world during 4:30-12:00 in-game time, and enters again, there is a 22% chance he will re-spawn (with a new shop inventory).
- Bound NPCs found underground can be freed by talking to them, after which they will always respawn whenever a vacant house is available. Having an empty room ready for them beforehand will cause them to move in as soon as they are off-screen.
- Bound NPCs can be found by listening to their "hurt" sounds, especially the Mechanic, as the Dungeon is teeming with enemies.
- A Housing area can be created where all the NPCs can have their biome-specific items: 300 Pink Ice Block, 100 mushroom grass, and 80 Lihzahrd brick in one screen where the houses are located.
- Drowning an NPC in water is an easy way to get NPC drops (safer than lava, and quicker than Rotten Eggs).
Emotes[edit | edit source]
- Although it may seem to be random, NPCs "emote" about things depending on their environment.

Trivia[edit | edit source]
- During a Blood Moon, most female NPCs use more irritable or aggressive dialogue than normal.
- The Mechanic is only one block wide while bound, whereas she is two blocks wide once talked to. This can be used to force her into a one block wide space. You can also find her on a 2 block space.
- The Cake emote strongly resembles the Slice of Cake unimplemented item.
- There are two unused emotes in the game code: Beer and Defender Medal.
- NPCs house the most references of any subject in Terraria.
- "NPC" is an abbreviation for "Non-Playable Character" as well.
References[edit | edit source]
- In video game development lingo, the term "NPC" technically includes any character not controlled by a player, including enemies. However, Terraria, along with its developers and fan community, generally use the term "NPC" to refer only to friendly automated characters that provide a service to players. This page is therefore only about those friendly NPCs.
