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 move into your world under specific conditions. She is one of the most sought-after NPCs due to her exclusive items and dialogue. To have the Princess move in, you must meet certain requirements related to other NPCs and the state of your world. HereÔÇÖs a detailed explanation of how to achieve this, along with tips, strategies, and considerations.

First, the Princess NPC will only move in if all other town NPCs (excluding Santa Claus and town pets) are present in your world. This means you must have every other NPC, such as the Guide, Merchant, Nurse, Arms Dealer, and so on, living in your world. Some NPCs, like the Tavernkeep and Golfer, are optional and do not need to be present for the Princess to move in. However, all the core NPCs must be housed and active. This requirement makes the Princess one of the last NPCs you can acquire, as youÔÇÖll need to progress through the game to unlock all the others.

To start, youÔÇÖll need to ensure you have suitable housing for all NPCs. Each NPC requires a valid house, which is a room with walls, a light source, a table, a chair, and an entrance. The room must also be in a biome that the NPC prefers or at least tolerates. For example, the Dryad prefers the Forest biome, while the Arms Dealer prefers the Desert. Placing NPCs in their preferred biomes not only makes them happier but also ensures they stay in your world. You can check if a house is valid by using the Housing Query tool, which is available in the gameÔÇÖs interface.

Once you have all the required NPCs housed, the Princess will automatically move into an available house. She does not require any specific biome or neighbor preferences, so you can place her anywhere in your world. However, if you want to maximize her happiness, you can place her near NPCs she likes, such as the Wizard or the Party Girl. Happiness affects the prices of items sold by NPCs, so keeping her happy can save you money when purchasing her exclusive items.

A common mistake players make is assuming that the Princess will move in as soon as they have most NPCs. However, she requires every single town NPC to be present, so double-check your list to ensure none are missing. Some NPCs, like the Angler or the Tax Collector, can be easy to overlook if you havenÔÇÖt completed their specific requirements. Additionally, make sure that all NPCs are alive and housed. If an NPC dies or their house is destroyed, the Princess will not move in until the issue is resolved.

Advanced players can optimize their NPC placement to maximize happiness and efficiency. For example, grouping NPCs who like each other in the same biome can create a highly efficient town. The Princess, for instance, likes the Wizard and the Party Girl, so placing them together in a Forest biome can create a happy and productive group. This setup not only benefits the Princess but also reduces the prices of items sold by all three NPCs.

Resource requirements for housing the Princess are minimal, as she does not need any special materials or structures. However, you will need to gather resources for building houses for all the other NPCs. Wood, stone, and torches are the basic materials youÔÇÖll need, but some NPCs may require more advanced materials like glass or silk. Preparing these resources in advance can save time and ensure a smooth process.

In terms of class and equipment considerations, there are no specific requirements for the Princess. However, since youÔÇÖll need to progress through the game to unlock all NPCs, having strong combat gear is essential. Defeating bosses like the Eye of Cthulhu, Skeletron, and the Wall of Flesh is necessary to unlock certain NPCs, so make sure your character is well-equipped with weapons, armor, and accessories. For example, a melee character might use a NightÔÇÖs Edge sword and Molten Armor, while a ranged character could use a Minishark and Necro Armor.

In summary, to have the Princess NPC move into your world, you must house every other town NPC first. Ensure all houses are valid and that no NPCs are missing or dead. Optimize your town layout to maximize happiness and efficiency, and prepare resources for building houses. With these steps, youÔÇÖll be able to welcome the Princess and enjoy her unique items and dialogue.
