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 progression. The Truffle is a unique NPC who sells mushroom-themed items, including the Autohammer, which is essential for crafting Shroomite armor. HereÔÇÖs a detailed guide on how to make the Truffle move in, including mechanics, strategies, and tips.

First, the Truffle will only move into a house located in a Glowing Mushroom biome. This biome is created by planting Mushroom Grass Seeds on Mud Blocks, which will spread and transform the area into a Glowing Mushroom biome. You can obtain Mushroom Grass Seeds by breaking glowing mushrooms found in underground mushroom biomes or by using a Staff of Regrowth on glowing mushrooms. Once you have the seeds, plant them on Mud Blocks in an area you want to convert. The biome will grow over time, and youÔÇÖll know itÔÇÖs active when the background changes, and glowing mushrooms start appearing.

Next, you need to build a suitable house for the Truffle. The house must meet the standard NPC housing requirements, which include walls, a light source, a table, a chair, and a door or platform entrance. The house must also be entirely within the Glowing Mushroom biome. You can check if the house is valid by using the Housing Query tool, which will tell you if the house is suitable for an NPC. Make sure the house is not too close to corruption, crimson, or hallow biomes, as these can interfere with NPC happiness and prevent the Truffle from moving in.

The Truffle will only appear after you have defeated at least one mechanical boss, such as the Destroyer, Skeletron Prime, or The Twins. These bosses are part of Hardmode progression, so youÔÇÖll need to prepare for these fights by gathering strong weapons, armor, and accessories. Once youÔÇÖve defeated a mechanical boss, the Truffle will have a chance to move into the Glowing Mushroom biome house if it meets all the requirements.

One common mistake players make is not ensuring the entire house is within the Glowing Mushroom biome. If even a small part of the house is outside the biome, the Truffle will not move in. To avoid this, use the Housing Query tool to confirm the houseÔÇÖs validity. Another mistake is not having enough space for the biome to grow. Make sure you plant enough Mushroom Grass Seeds and give the biome time to spread. If the biome is too small, the house may not register as being in the correct environment.

Advanced techniques include creating an artificial Glowing Mushroom biome near your main base for easier access to the Truffle. You can do this by digging out a large area and filling it with Mud Blocks, then planting Mushroom Grass Seeds. This allows you to control the biomeÔÇÖs location and size, making it easier to manage. You can also use the Clentaminator with Dark Blue Solution to create a Glowing Mushroom biome, but this method is more resource-intensive.

Resource requirements for this process include Mud Blocks, Mushroom Grass Seeds, and materials for building the house. Mud Blocks can be obtained by digging in the Underground Jungle or by using the Extractinator on Silt or Slush. Mushroom Grass Seeds are relatively easy to obtain once you find an underground mushroom biome. For the house, youÔÇÖll need wood, stone, or other building materials, depending on your design.

Class and equipment considerations are minimal for this task, as it primarily involves building and biome management. However, having a good pickaxe or drill will make gathering Mud Blocks and building the house easier. If youÔÇÖre creating an artificial biome, a Clentaminator can speed up the process, but itÔÇÖs not necessary.

In summary, to get the Truffle NPC to move in, you need to create a Glowing Mushroom biome, build a suitable house within it, and defeat at least one mechanical boss. Use the Housing Query tool to ensure the house is valid, and avoid common mistakes like having parts of the house outside the biome. Advanced techniques include creating an artificial biome near your base for convenience. With proper preparation and attention to detail, youÔÇÖll have the Truffle NPC in your world, ready to sell you valuable mushroom-themed items.
