How does NPC happiness work in Terraria?

Each NPC has a preferred biome and a set of liked and disliked neighbor NPCs. Place them in a loved/liked biome next to neighbors they like, and keep their crowding down, and their prices drop toward the 75% floor. Put them in a hated biome surrounded by NPCs they hate and prices climb to the 150% ceiling. Lower prices also used to be required to unlock Pylons, though that requirement was removed in 1.4.5.

What is the best NPC setup for happiness in Terraria?

Pair NPCs who like each other in a biome they love, in small groups of two or three so you also get the solitude bonus and avoid the crowding penalty. Classic pairs include Goblin Tinkerer + Mechanic (Underground), Arms Dealer + Nurse (Desert), and Dryad + Truffle near the Witch Doctor (Jungle). The Princess is liked by every NPC and dislikes no one, so she's a great filler anywhere.

Which biome does each Terraria NPC like?

It varies per NPC — for example the Guide and Zoologist like the Forest, the Arms Dealer and Steampunker like the Desert, the Goblin Tinkerer and Clothier like the Underground, and the Nurse, Wizard and Party Girl like the Hallow. Use the picker on this page to look up any NPC's loved and liked biomes instantly.

Terraria NPC Happiness — Who Goes Where

Q: Do you still need high happiness to buy a Pylon in Terraria?

No — as of Desktop 1.4.5.0, the happiness requirement to sell a Pylon was removed entirely. Any town NPC will now offer their biome's Pylon as long as they have at least one other town NPC nearby. Happiness now only affects prices, not Pylon access. To place and use a Pylon you still need at least two housed NPCs within range.

Stop cross-referencing a giant chart. Tap any NPC and see their ideal biome, the neighbors to put next to them, who to keep apart, and the setup that drives prices to the floor. Every town NPC's full preferences, current for Terraria 1.4.5.

How Happiness Actually Works

Happiness is a price multiplier. Every factor below stacks (multiplies), then the final buy price is clamped between 75% (best) and 150% (worst). Selling is the inverse.

Factor	Effect on buy price
Loved biome / loved neighbor	×0.88 each
Liked biome / liked neighbor	×0.94 each
Disliked biome / disliked neighbor	×1.06 each
Hated biome / hated neighbor	×1.12 each
Solitude bonus	×0.95 — ≤2 NPCs within 25 tiles & ≤3 within 25–120
Crowding penalty	×1.05 — per NPC beyond the 3rd within 25 tiles
Homeless / >120 tiles from home / in Corruption-Crimson-Dungeon	forced to 150%

The simple recipe: put an NPC in a biome they love, next to one or two neighbors they like, in a small group of 2–3. That hits the solitude bonus, dodges crowding, and lands prices near the 75% floor. The Princess is the cheat code — every NPC likes her and she hates no one, so she's perfect filler.

Pylons — What Changed in 1.4.5

If you read an older guide, ignore the "get happiness above 90% to unlock the Pylon" rule — that requirement was removed in 1.4.5.

As of Desktop 1.4.5, happiness no longer gates Pylons. Any town NPC will sell their biome's Pylon as long as they have at least one other town NPC nearby — regardless of price. Happiness now only affects prices. (To place and use a Pylon you still need two housed NPCs in range — town pets and the Old Man count.) So chase happiness for the discount, not the Pylon.

Do you still need happiness for Pylons?

No — the happiness requirement to sell a Pylon was removed in 1.4.5. Any NPC offers their biome Pylon with at least one other NPC nearby. Happiness now only affects prices. You still need two housed NPCs in range to place/use a Pylon.

What's the best happiness setup?

Pair NPCs who like each other in a biome they love, in groups of two or three (for the solitude bonus, no crowding). Classics: Goblin Tinkerer + Mechanic (Underground), Arms Dealer + Nurse (Desert), Dryad + Truffle by the Witch Doctor (Jungle). The Princess is liked by everyone and dislikes no one — ideal filler anywhere.

Why is the Princess special?

She has no biome preference, is liked by every other NPC, and has no disliked or hated neighbors. The only thing she dislikes is being lonely or in a crowd. That makes her the most flexible happiness booster in the game — drop her next to anyone.
