What are the best biome preferences for the Mechanic NPC in Terraria?

The Mechanic NPC in Terraria is a valuable character who sells wiring tools, traps, and other mechanical items essential for building complex contraptions and traps. To maximize her happiness, you need to place her in a biome she prefers and pair her with NPCs she likes. This will reduce her prices and increase her overall usefulness. HereÔÇÖs a detailed guide on how to achieve this.

The Mechanic prefers the Snow biome and dislikes the Desert biome. Her favorite neighbor is the Goblin Tinkerer, and she dislikes being near the Cyborg or the Steampunker. Placing her in the Snow biome with the Goblin Tinkerer nearby will make her happy, reducing the cost of her items by up to 15%. This is particularly useful because her items, such as wire cutters and pressure plates, are often needed in large quantities for building traps and mechanisms.

To set up her housing, youÔÇÖll need to create a suitable Snow biome. This can be done by placing at least 1,500 snow or ice blocks in an area. You can gather these blocks by mining in the Snow biome, which is naturally found in most worlds. Once you have enough blocks, create a small area in your base or a separate location and place the blocks to convert the area into a Snow biome. You can verify this by checking the background and music, which will change to reflect the biome.

Next, build a house for the Mechanic and the Goblin Tinkerer. The house should be at least 6 blocks wide and 10 blocks tall, with walls, a chair, a table, and a light source. Place the MechanicÔÇÖs house close to the Goblin TinkererÔÇÖs house to ensure they are neighbors. Avoid placing the Cyborg or Steampunker nearby, as this will reduce her happiness.

One common mistake is placing the Mechanic in the wrong biome or pairing her with the wrong NPCs. For example, placing her in the Desert biome or near the Cyborg will make her unhappy, increasing her prices and making her less useful. Another mistake is not verifying the biome conversion. Always check the background and music to ensure the area is correctly converted to a Snow biome.

Advanced techniques include creating a centralized Snow biome housing area for multiple NPCs who prefer this biome, such as the Tavernkeep and the Goblin Tinkerer. This can help you manage multiple NPCs efficiently and maximize their happiness. You can also use pylons to create a network of fast travel points, making it easier to access the Mechanic and other NPCs.

Resource requirements include snow or ice blocks, wood, stone, and other building materials. YouÔÇÖll also need to gather wiring tools and traps from the Mechanic, so having a good supply of coins is essential. Preparation involves mining in the Snow biome to gather the necessary blocks and setting up a suitable housing area before moving the Mechanic in.

Class and equipment considerations are minimal for this task, as it primarily involves building and resource gathering. However, having a good pickaxe and mobility items like wings or a grappling hook can make the process faster and easier. If youÔÇÖre playing in Hardmode, ensure you have adequate defense and weapons to handle any enemies that might spawn in the Snow biome.

In summary, to maximize the MechanicÔÇÖs happiness, place her in a Snow biome with the Goblin Tinkerer as her neighbor. Avoid placing her in the Desert biome or near the Cyborg or Steampunker. Create a suitable housing area, verify the biome conversion, and ensure she has the right neighbors. This will reduce her prices and make her more useful for your building and trapping needs.
