Building an NPC house in Terraria is essential because it allows Non-Playable Characters (NPCs) to move in, providing the player with valuable services like healing, trading, and crafting. Housing NPCs also help to unlock new items and gameplay features, enhancing the overall game experience. Additionally, having a secure home for NPCs helps protect them from monsters and other threats.
