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

The Merchant NPC in Terraria is one of the first NPCs players can acquire, and managing his happiness is important for reducing the prices of his goods and unlocking unique items like the Piggy Bank. The NPC happiness system in Terraria is based on biome preferences and neighbor preferences. For the Merchant, his preferred biome is the Forest, and he likes living near the Nurse and the Golfer. Understanding these preferences and how to optimize them will help you maximize his happiness and benefits.

To start, the Merchant prefers the Forest biome. This biome is the default surface biome where players begin the game, characterized by green grass, trees, and a generally peaceful environment. If you want to keep the Merchant happy, you should place his house in the Forest biome. However, if you are building a town or base in another biome, you can create an artificial Forest biome by planting at least 80 Forest grass blocks and a few trees. This will allow you to place the Merchant in a Forest biome even if your base is located elsewhere.

The Merchant also has specific neighbor preferences. He likes living near the Nurse and the Golfer. The Nurse is another early-game NPC who provides healing services, and the Golfer is an NPC who sells golf-related items and can be found in the Underground Desert. Placing the Merchant in a house near the Nurse and Golfer will increase his happiness. However, avoid placing him near NPCs he dislikes, such as the Angler or the Tax Collector, as this will decrease his happiness.

To build a suitable house for the Merchant, you will need to create a room that meets the basic housing requirements. A house must be at least 6 blocks wide and 10 blocks tall, with walls, a door, a table, a chair, and a light source. You can use any type of block for the walls and floor, but using materials that match the Forest biome, such as wood or living wood, can enhance the aesthetic. Once the house is built, assign the Merchant to it by using the housing menu.

One common mistake players make is overcrowding NPCs in a small area. While it might be tempting to place all NPCs in a single location for convenience, this can lead to decreased happiness for many NPCs, including the Merchant. To avoid this, spread out your NPCs in smaller groups, ensuring that each group is placed in their preferred biome and near their preferred neighbors. For example, you could create a small Forest village with the Merchant, Nurse, and Golfer living together, while other NPCs are placed in different biomes.

Advanced techniques for optimizing NPC happiness include creating multiple towns in different biomes. For example, you could have a Forest town with the Merchant, Nurse, and Golfer, a Desert town with the Arms Dealer and Nurse, and an Ocean town with the Angler and Pirate. This approach allows you to maximize happiness for all NPCs while also creating diverse and interesting bases.

Resource requirements for building a Forest biome and suitable housing are relatively low. You will need wood, which can be easily obtained by chopping down trees, and stone, which is abundant in the underground. For the walls, you can use wood or other materials like mud or clay. If you want to create an artificial Forest biome, you will need to gather Forest grass seeds, which can be obtained by cutting grass in the Forest biome.

In terms of class and equipment considerations, managing NPC happiness does not require specific gear or class builds. However, having a strong character with good mobility and combat abilities will help you gather resources and defend your base during events like Goblin Invasions or Blood Moons. It is also helpful to have a pickaxe or drill for mining materials and a weapon for dealing with enemies that might spawn near your base.

A specific example of optimizing the Merchant's happiness would be to create a Forest biome near your spawn point and build a small village with houses for the Merchant, Nurse, and Golfer. This setup ensures that the Merchant is in his preferred biome and near his preferred neighbors, maximizing his happiness. You can then expand this village by adding other NPCs in their preferred biomes, creating a thriving and efficient town.

In conclusion, managing the Merchant's happiness in Terraria involves placing him in the Forest biome and near the Nurse and Golfer. By following these steps and avoiding common mistakes like overcrowding, you can maximize his happiness and enjoy the benefits of reduced prices and unique items. With proper planning and resource management, you can create a thriving town that meets the needs of all your NPCs.
