Arms Dealer

The Arms Dealer is an NPC that will spawn once the following criteria have been met:
 * There is an empty house.
 * The player has at least one bullet or bullet-firing gun in their inventory (guns stored in storage items like chests do not count).

If the Arms Dealer is killed, he will only respawn if the above conditions are met again.

On the, when threatened by enemies, the Arms Dealer will use a Flintlock Pistol to defend himself. Once Hardmode begins, he upgrades to a Minishark for self-defense.

Tips

 * The easiest way to acquire a qualifying gun is to smash either a Shadow Orb or Crimson Heart in the Corruption or the Crimson. They will always drop a Musket or an Undertaker, respectively, on the first break.
 * The Musket and Undertaker can also be found in Corrupt Crates and Crimson Crates, respectively.
 * Other qualifying early guns include:
 * Boomstick (from Jungle Crates and Ivy Chests)
 * Handgun (from the Dungeon's Locked Gold Chests and )
 * (from Presents).
 * While it is called a 'gun', Flare Gun will not trigger the Arms Dealer, as it fires flares rather than bullets.

Trivia

 * The name Brimst may be a reference to, one of the ingredients of.
 * Unlike several other NPCs, who sell their own clothes on Halloween, the Arms Dealer sells the Nurse's clothes. On a technical level, this may be because the Nurse does not have a shop interface through which to sell her own clothes. It may also suggest a romantic relationship with her, therefore having access to her clothes.
 * The quote about the Guide Voodoo Doll still appears even if the Guide is dead, but the name will be random each time.
 * He seems to be attracted to both the Nurse and the Dryad. This is seen in his quote about the date with the Nurse, and the Dryad's quote about him flirting with her. He also flirts with the Mechanic, according to her quote about the pressure plate. But he seemingly has more of an interest in the Nurse.
 * The Arms Dealer and Guide seem to argue with each other through Emotes, implying they don't get along. This is further evidenced by his quote regarding the Guide Voodoo Doll.
 * The name Demetrius may be a reference to the play  by.
 * If you place the Arms Dealer and the Nurse together, no matter if they are in a hated biome or near a hated Town N.P.C, he will sell a pylon. This is most likely because of the Arms Dealer's and Nurse's relationship.
