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

To get the Truffle NPC to move into your world in Terraria, you need to meet specific requirements related to the environment and housing. The Truffle is a unique NPC who sells mushroom-themed items, including the Autohammer, which is essential for crafting Shroomite gear. HereÔÇÖs a detailed guide on how to make the Truffle move in, covering mechanics, strategies, and tips.

First, the Truffle requires an artificial Glowing Mushroom biome to move in. This biome is created by planting Mushroom Grass Seeds on Mud Blocks. You can obtain Mushroom Grass Seeds by breaking glowing mushrooms in the Underground Mushroom biome or by using a Staff of Regrowth on glowing mushrooms. To create the biome, you need a large enough area of Mud Blocks with Mushroom Grass. The biome is considered active when the background changes to the mushroom biome theme, and the music shifts to the mushroom biome track. The biome must also have at least 100 tiles of Mushroom Grass or Mushroom-related blocks to be valid.

Next, you need to build a suitable house for the Truffle within the artificial Glowing Mushroom biome. The house must meet the standard NPC housing requirements, which include having walls, a light source, a table, a chair, and a door or other entrance. The house must also be at least 6 blocks tall and 10 blocks wide internally. Make sure the house is fully enclosed and free of corruption, crimson, or hallow nearby, as these can invalidate the housing.

Once the biome and house are ready, the Truffle will move in if there is an available housing slot. If other NPCs are already occupying all available slots, you may need to build additional houses or relocate existing NPCs. The Truffle will not move in if the world is in pre-Hardmode, as he only appears in Hardmode. Ensure you have defeated the Wall of Flesh and entered Hardmode before attempting to get the Truffle.

A common mistake is not creating a large enough Glowing Mushroom biome. If the biome is too small, the background and music wonÔÇÖt change, and the Truffle wonÔÇÖt move in. Another mistake is placing the house too close to corruption, crimson, or hallow, which can prevent the Truffle from spawning. Always check the housing validity by using the housing query tool from the NPC menu.

For advanced techniques, consider building the Glowing Mushroom biome underground or in the sky. An underground biome can be easier to manage and protect from spreading biomes. A sky biome can be visually appealing and provide a unique base location. You can also use actuators to toggle the biome on and off, allowing you to control when the Truffle moves in or out.

Resource requirements include Mud Blocks, Mushroom Grass Seeds, and building materials for the house. Mud Blocks can be obtained by using the Extractinator on silt or slush, or by mining in the Jungle biome. Mushroom Grass Seeds are relatively easy to obtain, but you may need to explore the Underground Mushroom biome to gather enough. Building materials like wood, stone, or other blocks are needed for the house.

Class and equipment considerations are minimal for this task, as it primarily involves building and biome creation. However, having a pickaxe or drill with good mining speed can help gather resources faster. The Staff of Regrowth is useful for farming Mushroom Grass Seeds more efficiently.

In summary, to get the Truffle NPC to move in, create a valid Glowing Mushroom biome by planting Mushroom Grass Seeds on Mud Blocks, build a suitable house within the biome, and ensure the world is in Hardmode. Avoid common mistakes like small biomes or nearby corruption, and consider advanced techniques like underground or sky biomes. With proper preparation and resource management, you can successfully attract the Truffle to your world and access his unique items.
