What are the requirements for the Arms Dealer NPC to move in Terraria?

The Arms Dealer is one of the many NPCs in Terraria who can move into your world and provide valuable services. To get the Arms Dealer to move in, you need to meet specific requirements related to the game's progression and item availability. HereÔÇÖs a detailed explanation of how to achieve this, along with tips, strategies, and considerations to help you succeed.

First, the Arms Dealer will only move in if there is at least one gun or bullet-related item in your world. This means you need to acquire a gun, such as the Musket or the Undertaker, or a bullet item like Musket Balls. These items are typically found in the Corruption or Crimson biome, depending on your world type. In Corruption, you can find the Musket by smashing Shadow Orbs, which are located deep underground in the CorruptionÔÇÖs chasms. In Crimson, you can find the Undertaker by smashing Crimson Hearts, which are found in the CrimsonÔÇÖs underground caves. Both of these items are guaranteed drops from their respective sources, so you only need to break one Shadow Orb or Crimson Heart to obtain them.

Once you have a gun or bullet item in your inventory, the Arms Dealer will become eligible to move in. However, you also need to provide suitable housing for him. Housing in Terraria requires a room that meets specific criteria. The room must be at least 6 blocks wide and 10 blocks tall, with walls, a door, a light source, a flat surface item like a table or workbench, and a comfort item like a chair. The room must also be fully enclosed, with no gaps in the walls or ceiling. You can build this room anywhere in your world, but itÔÇÖs often convenient to place it near other NPCs to create a town.

One common mistake players make is not having a gun or bullet item in their inventory when trying to get the Arms Dealer to move in. Simply having the item in a chest or storage container is not enough. The item must be in your characterÔÇÖs inventory for the Arms Dealer to recognize it and move in. Another mistake is not providing suitable housing. If the room doesnÔÇÖt meet the requirements, the Arms Dealer wonÔÇÖt move in, even if you have the necessary items.

To optimize the process, you can prepare in advance by gathering the materials needed to build a suitable house before you even obtain the gun or bullet item. This way, as soon as you get the item, you can place the house and the Arms Dealer will move in immediately. Additionally, you can create multiple houses in advance to accommodate other NPCs, as having a town with multiple NPCs can provide benefits like reduced prices and access to unique items.

Resource requirements for this process are relatively low. YouÔÇÖll need basic building materials like wood, stone, and torches to create the house. If youÔÇÖre playing in a Corruption world, youÔÇÖll also need a hammer or explosives to break the Shadow Orbs. In a Crimson world, youÔÇÖll need a hammer or explosives to break the Crimson Hearts. These resources are easy to obtain early in the game, so you shouldnÔÇÖt have much trouble gathering them.

In terms of class and equipment considerations, any class can obtain the necessary items to summon the Arms Dealer. However, ranged characters may find this process particularly beneficial, as the Arms Dealer sells guns and ammunition, which are essential for ranged builds. If youÔÇÖre playing as a melee or magic character, you can still benefit from the Arms DealerÔÇÖs services, but you may not rely on his items as heavily.

A specific example scenario would be starting a new world and exploring the Corruption biome early on. You gather enough materials to craft a hammer or find explosives, then head underground to locate a Shadow Orb. After breaking the Shadow Orb, you obtain the Musket and Musket Balls. You then return to the surface and build a suitable house. Once the house is ready, the Arms Dealer moves in, and you can start purchasing guns and ammunition from him.

In summary, getting the Arms Dealer to move in requires obtaining a gun or bullet item, providing suitable housing, and ensuring the item is in your inventory. By following these steps and avoiding common mistakes, you can easily add the Arms Dealer to your town and take advantage of his services.
