Every Terraria Town NPC and How to Unlock Them

In the vast, procedurally generated world of Terraria, progression is measured not just by the bosses you slay or the ores you mine, but by the community you build. Non-Player Characters, or NPCs, are the backbone of any successful playthrough. They provide essential services ranging from basic supply sales and health restoration to advanced gear reforging and world-cleansing tools.

This comprehensive list covers every Town NPC currently available in Terraria, categorized by their game stage, along with the precise requirements needed to move them into your base.

The Foundation of NPC Housing

Before any NPC can join your world, you must provide a "Valid House." In Terraria terms, a house is not just a collection of blocks; it must meet specific internal criteria to be recognized by the game's housing algorithm.

Every valid house requires:

Size: A minimum of 60 total tiles (including the frame), though a standard 6x10 or 7x9 room is most efficient.
Frame: Solid blocks, platforms, or doors must enclose the room.
Background Wall: Player-placed walls are mandatory. Natural dirt or stone walls found in caves will not count.
Furniture: At least one "flat surface" item (like a Table, Workbench, or Bathtub) and one "comfort" item (like a Chair, Bed, or Sofa).
Light Source: A Torch, Lantern, or Chandelier must be present.
Entry: At least one door or wooden platform.

Once these conditions are met, you can use the Housing Menu (the house icon above your armor slots) to check if a room is suitable.

Pre-Hardmode Town NPCs

Pre-Hardmode is the early stage of the game, before defeating the Wall of Flesh. There are 18 NPCs you can recruit during this phase.

1. The Guide

The Guide is the first NPC you encounter, spawning instantly upon world creation.

Unlock Requirement: None. He is already there.
Role: He provides tips for beginners and, more importantly, shows you every possible crafting recipe for any item with the "Material" tag.
Strategy Note: Keep him safe early on. Later, you will need to sacrifice him (via the Guide Voodoo Doll) to summon the Wall of Flesh.

2. The Merchant

The Merchant is the quintessential general store owner.

Unlock Requirement: All players in the world must collectively have more than 50 Silver Coins in their inventories.
Role: Sells basic survival gear like Torches, Iron Anvils, Pickaxes, and Mining Helmets.
Player Experience: His Bug Net is an essential purchase for catching bait and critters.

3. The Nurse

The Nurse offers instant health restoration in exchange for coins.

Unlock Requirement: A player must have more than 100 maximum health (achieved by consuming a Life Crystal) and the Merchant must already be present.
Role: Heals the player and removes all active debuffs.
Strategy Note: Building a house for her near your boss arena can be a lifesaver, allowing for quick "emergency heals" during intense fights.

4. The Demolitionist

The Demolitionist is your primary source for high-damage explosives.

Unlock Requirement: A player must have an explosive item (like a Bomb, Dynamite, or Grenade) in their inventory, and the Merchant must be present.
Role: Sells Grenades, Bombs, and Dynamite.
Strategy Note: Grenades are incredibly powerful against early-game bosses like the Eye of Cthulhu and the Eater of Worlds.

5. The Dye Trader

For those who care about aesthetics, the Dye Trader is vital.

Unlock Requirement: A player must have a dye-related item (like a Blueberry, Strange Plant, or Pink Prickly Pear) in their inventory, and at least four other Town NPCs must exist.
Role: Sells the Dye Vat and basic dyes. He also exchanges "Strange Plants" for rare, animated dyes.

6. The Angler

The Angler is a unique NPC who does not sell items but provides daily quests.

Unlock Requirement: Found sleeping on the surface of the Ocean (at either the far left or right edge of the world). Simply wake him up to have him move in.

7. The Zoologist

The Zoologist is a specialized vendor focused on the Bestiary and critters.

Unlock Requirement: You must have completed at least 10% of the Bestiary (53 entries).
Role: Sells pet-related items, critter-themed vanity gear, and the highly useful "Guide to Critter Companionship," which prevents you from accidentally killing innocent animals.

8. The Dryad

The Dryad is the protector of the world's purity.

Unlock Requirement: Defeat any main boss (Eye of Cthulhu, Eater of Worlds, Brain of Cthulhu, or Skeletron).
Role: Sells Purification Powder, Sunflowers, and seeds. She also provides a "World Status" report, telling you the percentage of Corruption, Crimson, and Hallow.
Special Ability: During combat, she casts a "Dryad's Blessing" aura that increases player defense and health regeneration while damaging nearby enemies.

9. The Painter

The Painter allows for deep customization of your base's visual style.

Unlock Requirement: At least 8 other Town NPCs must be present in the world.
Role: Sells paints, wallpapers, and various paintings that change based on the biome he is currently in.

10. The Golfer

A niche NPC for those looking for a break from the monster-slaying.

Unlock Requirement: Found in the Underground Desert biome. You must interact with him to rescue him.
Role: Sells golfing equipment and the Lawn Mower, which prevents enemy spawns on mowed grass.

11. The Arms Dealer

The Arms Dealer is the most important NPC for ranged combat builds.

Unlock Requirement: A player must have a gun or ammunition in their inventory.
Role: Sells the Minishark, Illegal Gun Parts, Flintlock Pistols, and various types of Bullets.

12. The Tavernkeep

A crossover NPC from Dungeon Defenders II.

Unlock Requirement: Found unconscious anywhere in the world after defeating either the Eater of Worlds or the Brain of Cthulhu.

Widely considered the most important NPC in the game.

Unlock Requirement: Found bound in the Cavern layer after defeating a Goblin Army invasion.
Role: Sells the Tinkerer’s Workshop (allows combining accessories) and provides the "Reforge" service, which changes the modifiers on your weapons and accessories for a fee.

15. The Witch Doctor

A tribal NPC specializing in summoner and jungle-themed gear.

Unlock Requirement: Defeat Queen Bee in the Underground Jungle.

1. The Wizard

The primary vendor for magic users.

Unlock Requirement: Found bound in the Cavern layer after entering Hardmode.
Role: Sells the Crystal Ball, Spell Books, and the Ice Rod.

3. The Truffle

A sentient mushroom that only lives in a specific environment.

Special Trait: She is liked by all other NPCs, making her the perfect "buffer" for happiness management.

8. Santa Claus

A seasonal visitor.

Unlock Requirement: Defeat the Frost Legion invasion (summoned with a Snow Globe). He only appears during the Christmas season (December 15th – 31st).
Role: Sells Santa-themed vanity items and Christmas lights.

Special and Non-Resident NPCs

Not every friendly face in Terraria wants to live in your wooden boxes. Some prefer the nomadic life or have specific roles in the world.

The Traveling Merchant

Spawn Logic: Has a 22% chance to spawn every morning once you have at least 2 other Town NPCs. He stays for the day and leaves at 6:00 PM.
Inventory: He sells a random selection of rare items, including the Sitting Duck's Fishing Pole, Zapinator, and various exotic accessories.
Player Experience: Check his inventory every time he arrives; he often carries items required for the Ankh Shield or high-end build decorations.

The Skeleton Merchant

Spawn Logic: Found randomly in the Cavern layer. He does not move into a house.
Inventory: His shop changes based on the phases of the moon. He is a primary source for Yoyo accessories like the Yoyo Glove and Counterweights.

The Old Man

Role: He stands at the entrance of the Dungeon. During the day, he warns you not to enter. At night, talking to him allows you to summon Skeletron. Once Skeletron is defeated, he is freed and eventually returns as the Clothier.

Town Pets and Slimes

Introduced in later updates (1.4 and 1.4.4), these "NPCs" occupy housing but do not count toward the "all NPCs" requirement for the Princess.

Town Pets (Cat, Dog, Bunny)

How to Get: Purchase a "License" from the Zoologist. Once used, the pet will move into a vacant house.
Role: Purely cosmetic, but they contribute to the happiness of nearby NPCs.

Town Slimes

There are 8 collectible Town Slimes (e.g., Nerd Slime, Diva Slime, Squire Slime).

How to Get: Each has a unique unlock method, such as throwing a Sparkle Slime Balloon into Shimmer or finding one during a Slime Rain.
Role: Like pets, they add flavor to your town and can be petted.

How NPC Happiness Works (The Pylon System)

In version 1.4, Terraria introduced the Happiness System. Every NPC has preferences regarding where they live and who they live with.

Biome Preference: For example, the Painter loves the Jungle, while the Cyborg prefers the Snow biome.
Neighbor Preference: The Goblin Tinkerer loves being near the Mechanic, but hates living near the Clothier.
Crowding: NPCs prefer not to be crowded. Ideally, no more than two NPCs should live within 25 tiles of each other.

Why Happiness Matters:

Discounts: Happy NPCs sell items for up to 25% less. Unhappy NPCs can charge up to 150% of the base price.
Pylons: If an NPC is sufficiently happy and living in their preferred biome with a liked neighbor, they will sell a Pylon. Placing two Pylons of different biomes in your world allows you to teleport between them instantly, creating a fast-travel network across your map.

Optimal Pylon Setup Examples:

Forest Pylon: Guide + Merchant + Zoologist.
Underground Pylon: Goblin Tinkerer + Mechanic (They love each other).
Desert Pylon: Arms Dealer + Nurse (The "power couple" for cheap heals).
Ocean Pylon: Angler + Pirate + Stylist.
Hallow Pylon: Party Girl + Wizard + Tavernkeep.

Summary of NPC Progression

Building a thriving town in Terraria is a step-by-step process. Start with the basics (Guide, Merchant, Nurse) to survive the early nights. Focus on the Goblin Tinkerer as soon as you find him, as his Reforge ability is the single biggest power spike for your character. In Hardmode, prioritize the Steampunker to protect your world from being consumed by the "V-shape" of corruption that spawns after the Wall of Flesh dies.

By understanding the unlock conditions and housing requirements of these 26+ characters, you turn the hostile world of Terraria into a manageable, interconnected civilization.

Frequently Asked Questions

What happens if an NPC dies?

Do not worry; death is not permanent for NPCs. As long as you have a valid, vacant house, the NPC will respawn the following morning (between 4:30 AM and 6:00 PM) once the conditions that originally summoned them are still met.

Can I move an NPC to a different house?

Yes. Open your inventory and click the Housing icon. You will see a list of NPC heads. Click an NPC's head and then click the room you want them to move into. They will teleport to the new room the next time they are off-screen during the night or a rainy day.

Why won't the Merchant/Arms Dealer/Nurse spawn?

Ensure the specific inventory requirement is met (e.g., 50 silver for the Merchant) and that you have a completely valid house. Common mistakes include missing a single background wall tile or placing the house too close to the Corruption or Crimson biomes.

How do I get the Princess to arrive?

The Princess is the ultimate reward for recruitment. You must have every other resident NPC living in your world simultaneously. This includes all Pre-Hardmode and Hardmode NPCs, but excludes Santa Claus (unless it's December) and Town Pets/Slimes.
