How do I make the Arms Dealer NPC move in Terraria?

To make the Arms Dealer NPC move into your world in Terraria, you need to meet specific conditions. The Arms Dealer is a valuable NPC who sells guns, ammunition, and other ranged weapons, making him essential for players focusing on the Ranger class. HereÔÇÖs a detailed guide on how to get him to move in, along with tips and strategies to ensure success.

First, the Arms Dealer will only appear if two conditions are met. You must have at least one gun in your inventory, and there must be an available house for him to move into. Guns are items like the Musket, which can be found in Shadow Chests in the Corruption biome, or the Undertaker, found in Crimson Chests in the Crimson biome. Alternatively, you can craft a gun using illegal gun parts, which are sold by the Arms Dealer himself, but this requires him to already be in your world, so itÔÇÖs not helpful for initially spawning him. Once you have a gun, ensure you have a suitable house built. A house must meet specific requirements, such as being at least 6 blocks wide and 10 blocks tall, having walls, a door, a table, a chair, and a light source. The house must also be in a valid location, meaning it cannot be in an evil biome like Corruption or Crimson, or in a dangerous area like the Dungeon.

To prepare for the Arms DealerÔÇÖs arrival, you should gather resources like wood, stone, and torches to build a house. If youÔÇÖre early in the game, focus on exploring the Corruption or Crimson biome to find a gun. Defeating the Eater of Worlds in the Corruption or the Brain of Cthulhu in the Crimson can help you access Shadow or Crimson Chests, respectively. These bosses drop materials that allow you to craft better gear, which will help you survive in these dangerous biomes. Once you have a gun, return to your base and build a house. Place the house in a safe area, preferably near other NPCs to maximize happiness, which can lead to discounts on items sold by the Arms Dealer.

A common mistake players make is not having a gun in their inventory when trying to spawn the Arms Dealer. Simply having a gun in a chest or storage item wonÔÇÖt count. The gun must be in your main inventory. Another mistake is building a house that doesnÔÇÖt meet the requirements. Double-check the size, walls, and furniture to ensure the house is valid. If the Arms Dealer doesnÔÇÖt move in immediately, wait a bit, as NPCs sometimes take time to appear.

Advanced techniques include optimizing NPC happiness to reduce prices and increase the chance of obtaining unique items. The Arms Dealer prefers the Desert biome and likes living with the Nurse and the Steampunker. Placing him in a Desert biome with these NPCs nearby will make him happier, leading to better prices. Additionally, you can use pylons to create a fast-travel network between biomes, making it easier to access the Arms Dealer and other NPCs.

Resource requirements for this process are minimal. YouÔÇÖll need basic building materials like wood and stone, which are easy to gather early in the game. If youÔÇÖre struggling to find a gun, consider crafting a bow and arrows as a temporary ranged weapon while you explore the Corruption or Crimson biome. For combat, equip armor and accessories that boost your defense and mobility, such as Hermes Boots or a Cloud in a Bottle. These will help you navigate dangerous areas and avoid enemies while searching for a gun.

In summary, to make the Arms Dealer move in, obtain a gun and build a suitable house. Explore the Corruption or Crimson biome to find a gun, and ensure your inventory meets the requirements. Build a house in a safe area, and consider optimizing NPC happiness for better prices. Avoid common mistakes like not having a gun in your inventory or building an invalid house. With these steps, youÔÇÖll have the Arms Dealer in your world, ready to supply you with powerful ranged weapons.
