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 Mobile only.pngMobile version, you can't reforge items added in 1.2, except for accessories.
