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

To get the Arms Dealer NPC to move into your world in Terraria, you need to meet specific requirements. The Arms Dealer is a valuable NPC who sells guns, bullets, and other ranged weapons, making him essential for players focusing on ranged combat. HereÔÇÖs a detailed guide on how to meet the requirements and make him move in.

First, the Arms Dealer will only appear if at least one player in the world has a gun in their inventory. Guns are ranged weapons that use bullets as ammunition. Some common early-game guns include the Musket, which can be found in Shadow Chests in the Corruption biome, or the Undertaker, found in Crimson Chests in the Crimson biome. If you donÔÇÖt have a gun yet, youÔÇÖll need to explore these biomes and locate their respective chests. Breaking a Shadow Orb in the Corruption or a Crimson Heart in the Crimson biome will also guarantee a gun drop, but this will trigger the Goblin Army event if itÔÇÖs your first time breaking one.

Once you have a gun, the Arms Dealer will become eligible to move in. However, he still requires a suitable house. A house in Terraria must meet specific criteria to be considered valid for an NPC. It needs to be at least 6 blocks wide and 10 blocks tall, with walls, a door, a table, a chair, and a light source. The walls must be player-placed and not naturally occurring. You can craft walls using wood or other materials at a workbench. Make sure the house is fully enclosed and free of corruption, crimson, or hallow, as these biomes can invalidate housing.

To prepare for the Arms DealerÔÇÖs arrival, gather the necessary materials for building a house. Wood is the easiest material to obtain early in the game, so chop down trees with an axe to collect it. YouÔÇÖll also need torches for light, which can be crafted using wood and gel from slimes. Place the house in a safe area, preferably near other NPCs, as the Arms DealerÔÇÖs happiness increases when he is near the Nurse and the Steampunker. NPC happiness affects the prices of their goods, so keeping him happy will save you money.

A common mistake players make is forgetting to check if the house is valid. Use the housing query tool (a house icon in the inventory menu) to check if the house meets all requirements. Another mistake is not having a gun in the inventory when trying to spawn the Arms Dealer. Always double-check that at least one player has a gun before expecting him to move in.

For advanced players, optimizing the Arms DealerÔÇÖs happiness can lead to significant discounts. Place him in the Desert biome with the Nurse and Steampunker to maximize his happiness. This setup will reduce the cost of his items, making it cheaper to buy bullets and guns. Additionally, consider building a teleporter network to quickly access the Arms DealerÔÇÖs shop from different parts of your world.

Resource-wise, youÔÇÖll need wood, torches, and basic furniture like tables and chairs. These are easy to gather early in the game, so focus on exploring and gathering materials as soon as possible. If youÔÇÖre playing in a Corruption or Crimson world, prioritize breaking Shadow Orbs or Crimson Hearts to obtain a gun quickly. Be prepared for the Goblin Army event, as it will spawn shortly after breaking your first orb or heart.

In terms of class and equipment, the Arms Dealer is particularly useful for ranged players. If youÔÇÖre focusing on ranged combat, prioritize obtaining a gun and bullets early on. The Musket or Undertaker are excellent starting weapons, and the Arms Dealer sells ammunition to keep you stocked. For melee or magic players, the Arms Dealer is still useful for purchasing guns as backup weapons or for specific situations where ranged combat is advantageous.

In summary, to get the Arms Dealer to move in, ensure you have a gun in your inventory and build a valid house. Check the houseÔÇÖs validity, optimize his happiness for discounts, and prepare for the Goblin Army if youÔÇÖre breaking orbs or hearts. With these steps, youÔÇÖll have the Arms Dealer in your world, ready to supply you with powerful ranged weapons and ammunition.
