What are the best NPC pairings for the Snow biome in Terraria?

In Terraria, the Snow biome is a unique and challenging environment that requires careful planning when it comes to NPC housing and happiness. The happiness system in Terraria is designed to reward players who strategically place NPCs in biomes they prefer and pair them with neighbors they like. This system affects the prices of items sold by NPCs, as well as their willingness to sell certain items. To maximize happiness in the Snow biome, you need to understand the mechanics, plan your NPC pairings, and build suitable housing.

The happiness system works by assigning each NPC a preferred biome and preferred neighbors. When an NPC is placed in their preferred biome and near NPCs they like, their happiness increases. This leads to discounts on items they sell and, in some cases, unlocks special items. Conversely, placing an NPC in a biome they dislike or near NPCs they dislike will decrease their happiness, leading to higher prices and potential refusal to sell certain items. For the Snow biome, certain NPCs thrive better than others, and pairing them correctly is key.

To start, you need to identify which NPCs prefer the Snow biome. The Mechanic, Goblin Tinkerer, and Tavernkeep are among the NPCs who enjoy the Snow biome. The Mechanic prefers the Snow biome and likes the Goblin Tinkerer as a neighbor. The Goblin Tinkerer, on the other hand, prefers the Underground biome but can still be placed in the Snow biome if paired correctly. The Tavernkeep also enjoys the Snow biome and can be paired with the Mechanic or Goblin Tinkerer for optimal happiness.

To set up your Snow biome housing, you will need to create suitable homes for these NPCs. Each house must meet the basic requirements: it must have walls, a chair, a table, a light source, and be at least 60 tiles in size. You can build these houses close to each other to ensure the NPCs are neighbors. For example, you can place the Mechanic and Goblin Tinkerer in adjacent houses in the Snow biome. This pairing will keep both NPCs happy, as the Mechanic likes the Snow biome and the Goblin Tinkerer, while the Goblin Tinkerer benefits from being near the Mechanic.

One important tip is to avoid overcrowding. While it might be tempting to place multiple NPCs in the same area, overcrowding can lead to decreased happiness. Each NPC needs enough space to feel comfortable, so spread out your houses accordingly. Additionally, avoid placing NPCs in biomes they dislike. For example, the Dryad dislikes the Snow biome, so placing her there will make her unhappy and increase her prices.

Resource requirements for building in the Snow biome include snow blocks, ice blocks, and boreal wood. These materials are abundant in the Snow biome and can be used to create thematic houses that blend well with the environment. You can also use furniture crafted from these materials to enhance the aesthetic appeal of your NPC homes. For example, boreal wood furniture is a great choice for Snow biome housing.

When it comes to combat and defense, the Snow biome can be dangerous due to enemies like Ice Golems and Wolves. To protect your NPCs, consider building a wall around your housing area or using traps and defensive structures. This will help keep your NPCs safe during events like Blood Moons or Goblin Invasions.

Advanced techniques include using pylons to create a network of fast travel points. If you have multiple NPCs in the Snow biome, you can set up a Snow Pylon, which allows for quick travel between biomes. To unlock the Snow Pylon, you need at least two NPCs in the Snow biome with high happiness levels. This is another reason why proper NPC pairings are crucial.

In summary, achieving optimal NPC happiness in the Snow biome involves understanding the preferences of each NPC, building suitable housing, and pairing them with compatible neighbors. By focusing on NPCs like the Mechanic, Goblin Tinkerer, and Tavernkeep, you can create a thriving Snow biome community. Avoid common mistakes like overcrowding and placing NPCs in biomes they dislike. Use resources like snow blocks and boreal wood to build thematic houses, and consider defensive structures to protect your NPCs. With careful planning and execution, you can maximize happiness in the Snow biome and enjoy the benefits of discounted prices and unique items.
