Welcome to our guide to Terraria NPCs. NPCs are characters in Terraria that you cannot play. Their primary purpose is to provide useful information to you and help you in the game. To interact with an NPC, stand near the NPC and use the Open/Activate button on them. (This is usually the Right Click button on a mouse, the B button on Xbox, and the Circle button Playstation.) Some NPCs will sell you items and some can also purchase items from you for coins.
We've put together a guide on how to obtain each NPC, the items they drop, the items they sell, their defending weapon, and their stats (such as max life, defense, damage, knockback resistance, etc.). CLick on an NPC's name to see more information.
