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, covering 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. You can obtain Mushroom Grass Seeds by breaking glowing mushrooms in existing Glowing Mushroom biomes or by defeating Plantera, which increases the drop rate. To create a Glowing Mushroom biome, you need at least 100 Mud Blocks with Mushroom Grass growing on them. The biome will have a distinct background, music, and glowing mushroom enemies like Spore Zombies and Fungi Bulbs.

Once youÔÇÖve created a Glowing Mushroom biome, you need to build a suitable house for the Truffle. The house must meet the standard NPC housing requirements: it must have 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 from the Housing menu. If the house is valid, the Truffle will move in once there is an available slot and the conditions are met.

One important consideration is that the Truffle will only move in if you are in Hardmode. Hardmode is activated by defeating the Wall of Flesh in the Underworld. Before Hardmode, the Truffle will not appear, even if you have a valid house in a Glowing Mushroom biome. Make sure youÔÇÖve progressed far enough in the game before attempting to summon the Truffle.

A 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. Use the Housing Query tool to confirm the biome boundaries. Another mistake is not having enough Mushroom Grass Seeds to create a large enough biome. You may need to farm more seeds or wait for the grass to spread naturally.

For advanced techniques, you can create an artificial Glowing Mushroom biome above ground. This allows you to place the TruffleÔÇÖs house closer to your main base, making it easier to access his shop. To do this, build a platform high above the ground and place Mud Blocks with Mushroom Grass Seeds. Ensure the biome is large enough to trigger the background and music change. This method is especially useful if you want to keep all your NPCs in one area for convenience.

Resource requirements for this process include Mud Blocks, Mushroom Grass Seeds, and building materials for the house. Mud Blocks can be found in the Jungle biome or crafted from Dirt Blocks at a Furnace. Mushroom Grass Seeds are obtained from glowing mushrooms or enemies in the Glowing Mushroom biome. YouÔÇÖll also need basic building materials like Wood, Stone, and Torches for the house.

In terms of class and equipment, there are no specific requirements for summoning the Truffle. However, if youÔÇÖre creating an artificial Glowing Mushroom biome above ground, you may need mobility items like Wings or a Grappling Hook to access the area easily. Combat gear is also recommended if youÔÇÖre farming Mushroom Grass Seeds in a natural Glowing Mushroom biome, as the enemies can be challenging.

An example scenario is creating a Glowing Mushroom biome in the Cavern layer. This is a common strategy because the Cavern layer already has Mud Blocks, making it easier to spread Mushroom Grass. You can build a house here and ensure itÔÇÖs valid for the Truffle. Another scenario is creating an artificial biome above ground near your main base. This requires more effort but provides easier access to the TruffleÔÇÖs shop.

In summary, to get the Truffle to move in, create a Glowing Mushroom biome using Mud Blocks and Mushroom Grass Seeds, build a valid house within the biome, and ensure youÔÇÖre in Hardmode. Avoid common mistakes like incomplete biomes or invalid housing, and consider advanced techniques like artificial biomes for convenience. With proper preparation and resource management, you can successfully summon the Truffle and access his unique items.
