Arms Dealer – Overview

The Arms Dealer is one of the first NPCs you’ll have in the pre-Hardmode game. He sells a variety of weapons and ammunition, which scales depending on the difficulty level and player-defeated mechanical bosses.

Once exposed to enemy monsters, he’ll defend himself with a Flintlock Pistol. It’s a relatively weak gun, but once you progress through Hardmode, he’ll gain stats and use the Minishark.

This NPC likes the Desert but dislikes the Snow biome.

Spawning

Getting the Arms Dealer to move in is easy. Once at least one bullet or gun type is in the player’s inventory (any), it guarantees that he’ll appear in a moment. Note that if they’re in storage items, it won’t count. Don’t forget to furnish the empty house and make it suitable for living first, so he moves in!

Since finding equipment is hard, we recommend an underground adventure on either the Corruption or the Crimson (easiest way). You’ll soon find Shadow Orbs or Crimson Hearts covered with impenetrable blocks your Pickaxe usually can’t break. However, you can blow them away with bombs, and it usually works.

Once destroyed, you’ll get a Musket or an Undertaker (also found in Corrupt Crates or Crimson Crates).

Alternatively, you can get a Boomstick from Ivy Chests and Jungle Crates. Descending below the Dungeon is also a guarantee to obtain a Handgun – but defeat Skeletron first! Lastly, the dropped ammo from Pigronata also works, although you need Party Girl in your town.

Relationships

The Arms Dealer prefers to live near the Nurse, although also attracted to the Dryad. Moreover, the Princess, the Mechanic, and the Steampunker are also okay as they share a good friendship.

However, the Golfer and the Demolitionist may be a problem as the Weapons Dealer dislikes them.
