Goblin Tinkerer

The Goblin Tinkerer is an NPC that sells several unique items and provides the Reforge function. He can be acquired after a Goblin Army has been defeated, spawning randomly in open areas in the Cavern layer. He will appear to be bound at first, and like the Mechanic, Wizard and Stylist, talking to him in this state will free him. He will then respawn as long as a vacant House is available.

The Goblin's reforge option allows the player to spend a sum of Coins to randomize the Modifier for his or her weapon or accessory.

In the, you can only reforge items by dragging the desired item and dropping it at his face icon when spoken to. Then you have to open his shop and press the desired item and press reforge.

Once the Goblin Tinkerer has been freed, he will sell the following:

Names
The tinkerer may have any of the following names:

Tips

 * He periodically spawns near the player as they travel the Cavern layer, respawning if they get too far away. Therefore, spending hours clearing the map and searching every tunnel is unnecessary.
 * Using a Hunter Potion will cause the bound goblin to light up, making him easier to find.
 * If you did find him at one point but managed to lose him for whatever reason, you can use a King Statue to summon him.
 * As with any NPC, his icon appears on the map.
 * While the Goblin Tinkerer can be found in any open area underground, bound NPCs may be easier for players to find in the Dungeon, as it is an expansive and easily navigated underground space.

Trivia

 * As evidenced by some of his quotes, the Goblin Tinkerer has a crush on the Mechanic, and, referenced by some of her quotes, she has a crush on him too.
 * The quote, "Yo, I heard you like rockets and running boots, so I put some rockets in your running boots," is a reference to the "yo dawg" meme.

Quotes

 * "Hey... what's [Name of Mechanic] up to? Have you... have you talked to her, by chance?" (only when the Mechanic is present)
 * "I tried to visit [Name of Stylist] one time. She just looked at me and said 'nope.' (only when the Stylist is present)

During day:

During Night:

When Homeless:
 * "I can't believe they tied me up and left me here just for pointing out that they weren't going east!" (referring to the Goblin Tinkerer initially appearing bound; and east/west and sunrise/sunset being inconsistent in Terraria, or the east/west reversal from their typical directions in real-world maps)

When Rescued
 * "Thank you for freeing me, human. I was tied up and left here by the other goblins. You could say that we didn't get along very well."
