terrariumscontains many unique characters known as NPCs - constant patrons who will help players through all their trials and tribulations, as long as they have a home. The game features dozens of NPCs with different personalities, tastes, and purposes that players benefit from. As they are a predominant part of the game, players should understand everything there is to know about NPCs. So every NPC is hereterrariums- and how to create them.

Housing and Happiness

Every NPC in Terraria (and how to spawn them) (2)

NPCs have their respective spawn requirements, but most share housing needs. Even naturally spawning NPCs like the guide need a house if they die to not respawn. As such, players must ensure they have enough houses for current and future NPCs and make sure they are suitable.

There are several requirements for a house to be considered suitable; It must be at least 60 tiles in size and consist of a roof, floor, walls, back walls, light sources, flat surface furniture and comfort furniture. Also, a house is not viable if it is nearby or in an evil biome, e.g. B. the Corrupt and the Crimson.

Another important consideration for most NPCs is their happiness - the measure of their happiness or dissatisfaction, which is affected by their environment. Each NPC has biome and neighbor preferences that dramatically affect their mood and attitude towards players, along with the benefits and services they provide.

NPCs' happiness can cause the prices of their services to go up or down and can affect their stocks when selling items. The happier an NPC is, the more affordable their prices become and the more supplies they offer. On the other hand, the more unlucky an NPC is, the more expensive things become and the less supplies they offer.
