What are the requirements for the Princess NPC to move in Terraria?

The Princess NPC in Terraria is a unique and late-game character who can only move in under very specific conditions. She is tied to the game's NPC happiness system and requires players to meet certain criteria before she becomes available. HereÔÇÖs a detailed explanation of how to get the Princess to move in, along with tips, strategies, and considerations to help you achieve this.

First, the Princess NPC will only appear after all other town NPCs (excluding Santa Claus and town pets) have moved into your world. This means you must have every other NPC, such as the Guide, Merchant, Nurse, and so on, living in your town. Some NPCs, like the Tavernkeep and Golfer, are optional but still count toward this requirement. Additionally, the Princess will only spawn if there is at least one other NPC living in the same town, as she cannot be the sole resident.

To prepare for the Princess, you need to ensure that all other NPCs are housed and happy. This involves building suitable housing for each NPC, which requires a room with walls, a light source, a table, a chair, and a door or entrance. The room must also be in a valid biome, as some NPCs have specific biome preferences. For example, the Arms Dealer prefers the Desert biome, while the Dryad prefers the Jungle. Keeping NPCs happy is important because it reduces the prices of their goods and can lead to unique items, such as the Pylon system, which allows for fast travel between biomes.

Once all NPCs are housed, the Princess will automatically move into an available house. She does not require any special biome or neighbor preferences, but keeping her happy can still be beneficial. The Princess sells unique items, such as the Royal Scepter, which summons a flying familiar, and the Royal Delight, a vanity item. Her happiness is influenced by her neighbors and biome, so placing her near NPCs she likes, such as the Wizard or the Truffle, can improve her mood and reduce her prices.

A common mistake players make is forgetting to house all NPCs, especially those that are harder to obtain, like the Angler or the Tax Collector. Make sure to check your NPC list and ensure everyone is accounted for. Another mistake is not having enough housing available. The Princess requires a valid house, so always have at least one empty room ready for her. Additionally, players sometimes overlook the importance of NPC happiness, which can lead to higher prices and less efficient town management.

Advanced techniques for optimizing your town include using the Pylon system to create a network of fast travel points. This requires placing NPCs in their preferred biomes and pairing them with neighbors they like. For example, the Nurse and Arms Dealer like each other and prefer the Desert biome, making them a good pair for a Desert Pylon. This not only improves their happiness but also makes it easier to travel across your world.

Resource requirements for housing the Princess are minimal, as she only needs a standard house. However, preparing for all other NPCs can be resource-intensive. You will need plenty of wood, stone, and other building materials to create houses in various biomes. Crafting stations, such as the Sawmill and Loom, are essential for creating furniture and walls. Additionally, you may need to gather biome-specific materials, such as Cactus for the Desert or Mushroom Grass for the Mushroom biome.

Class and equipment considerations are not directly tied to the Princess, but having a well-equipped character can make it easier to gather resources and defend your town during events. For example, a melee character with high defense can handle invasions more effectively, while a ranged character can quickly gather materials from afar. Magic and summoner classes also have their advantages, depending on your playstyle.

In summary, getting the Princess to move in requires housing all other NPCs and ensuring they are happy. Build suitable houses in various biomes, pair NPCs with their preferred neighbors, and use the Pylon system to optimize your town. Avoid common mistakes like forgetting to house all NPCs or neglecting their happiness. With proper preparation and resource management, you can welcome the Princess to your town and enjoy her unique items and services.
