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

The Princess is one of the most unique NPCs in Terraria, and her arrival is tied to specific conditions that players must meet. She is the final NPC to move into your world, and her presence is a sign that you have progressed significantly in the game. To get the Princess to move in, you must first meet several key requirements. These requirements are tied to the game's progression and the presence of other NPCs.

First, the Princess will only appear in a world where all other town NPCs are present. This means you must have every other NPC in the game living in your world. This includes NPCs like the Guide, Merchant, Nurse, Arms Dealer, Dryad, and many others. Some NPCs, like the Tavernkeep and the Golfer, are optional but still count toward this requirement. Additionally, NPCs tied to specific events or conditions, such as the Angler, Stylist, and Tax Collector, must also be present. This means you need to complete various tasks, such as fishing for the Angler, rescuing the Stylist from Spider Caves, and purifying the Tax Collector in the Dungeon.

Once all other NPCs are present, the Princess will automatically move into an available house. She does not require any specific biome or neighbor preferences, unlike other NPCs. However, it is important to ensure that you have enough housing for all NPCs, including the Princess. Each NPC requires a valid house, which must meet the game's housing criteria. A valid house must have walls, a light source, a table or workbench, a chair, and a door or other entrance. The house must also be in a safe area, free from corruption, crimson, or hallow.

To prepare for the Princess's arrival, you should focus on completing the requirements for all other NPCs. This involves progressing through the game's various stages, defeating bosses, and completing specific tasks. For example, the Mechanic NPC requires you to rescue her from the Dungeon, while the Wizard NPC appears after defeating the Wall of Flesh and entering Hardmode. Some NPCs, like the Truffle, require specific biomes, so you may need to create artificial biomes to meet their requirements.

One common mistake players make is overlooking optional NPCs or forgetting to create housing for them. It is important to keep track of which NPCs you have and which ones are still missing. You can check the housing menu to see which NPCs are present and which houses are available. Another mistake is not preparing enough housing for all NPCs, which can delay the Princess's arrival. Make sure to build extra houses as you progress through the game to accommodate new NPCs.

Advanced players can optimize their NPC housing by creating compact, efficient towns that maximize happiness. NPC happiness affects their prices and can lead to discounts on items. While the Princess does not have specific biome or neighbor preferences, other NPCs do, so placing them in their preferred biomes and near their favorite neighbors can improve overall happiness. For example, the Nurse and Arms Dealer like each other, so placing them in the same biome can increase their happiness.

Resource requirements for housing are relatively simple. You will need basic building materials like wood, stone, and torches. As you progress, you may want to use more advanced materials like glass, bricks, or themed blocks to create aesthetically pleasing houses. Crafting stations like the Sawmill and Workbench are essential for creating furniture and other housing components.

In terms of class and equipment considerations, the Princess's arrival is not tied to any specific class or gear. However, progressing through the game to meet the requirements for all NPCs will require you to engage in combat, exploration, and crafting. Depending on your chosen class, you may need to focus on specific weapons, armor, and accessories to defeat bosses and complete tasks. For example, melee players may need strong swords and armor, while ranged players may need bows, guns, and ammunition.

A specific example of preparing for the Princess's arrival would be creating a central town with housing for all NPCs. This town could be located in the Forest biome, which is neutral and does not negatively affect most NPCs' happiness. You could build multiple houses in a compact layout, ensuring each house meets the game's housing criteria. As you progress and unlock new NPCs, you can assign them to the available houses. Once all NPCs are present, the Princess will move into the next available house.

In summary, the Princess's arrival in Terraria is a milestone that signifies you have completed much of the game's content. By ensuring all other NPCs are present and providing adequate housing, you can welcome the Princess to your world. Pay attention to NPC requirements, avoid common mistakes, and optimize your town for happiness to make the process smoother. With proper preparation and progression, the Princess will become a valuable addition to your Terraria world.
