Combining items in Terraria is essential to getting better equipment, accessories, armor, and weapons.

However, doing so can be quite challenging.

After all, there are many factors to consider, including the crafting station required, whether or not the desired item would be beneficial to your class setup, and the items needed.

While it may take a while to get the hang of it, learning to combine items is pretty much a necessity for progression in Terraria – particularly mid to late game. This post will walk you through the ins and outs of how to combine items in Terraria.

Tinkerer’s Workshop

The first thing to understand about combining items in Terraria is that the main crafting station for this process is called the Tinkerer’s Workshop.

It allows you to combine two or more items into one item, often having all the abilities of the combined items and an extra one.

This makes the ability to combine some items infinitely useful in saving accessory slots, as the amalgamation of three items into one, for example, means that you only need to use one accessory slot for the benefits of all three items.

The Tinkerer’s Workshop cannot be crafted. Instead, it must be purchased from the Goblin Tinkerer NPC for 10 gold coins.

10 gold coins may seem a large amount at first, especially earlier on in the game; however, it’s entirely worth getting as soon as you can.

The ability to combine items and their abilities is majorly important in accessory slot reservation, so the 10 gold coins are a no-brainer.

When an item is crafted or combined in the Tinkerer’s Workshop, it’ll automatically be assigned a random prefix, making it better or worse.

If you get a prefix that you don’t like, you can always reforge your item by talking to the Goblin Tinkerer.

As mentioned, before getting the Tinkerer’s Workshop, you must first get the Goblin Tinkerer NPC to move into your town, which can be a challenge in itself.

Not only does the Goblin Tinkerer allow the purchase of several Goblin Tinkerer-exclusive items (including the Tinkerer’s Workshop), but he also provides the “Reforge” function.

Reforging items gives them a different, random prefix. Prefixes change the stats of the item in question. These stat changes can either be positive or negative – depending on the prefix.

It’s worth noting that reforging an item costs coins, but you can reforge an item as many times as you like. This means that you can keep reforging until you get your desired prefix.


To get the Goblin Tinkerer, you must have defeated a Goblin Army. During the early stages of the game, this can be incredibly difficult, particularly if you’ve just defeated the Wall of Flesh and entered hardmode.

Once you have defeated the Goblin Army, the next stage is also somewhat challenging, as the Goblin Tinkerer won’t just spawn as many other NPCs do; instead, he must be found.

The Goblin Tinkerer can be randomly found in the cavern layer. Note that he can spawn in artificial biomes, so long as they remain in the cavern layer.

Initially, the Goblin Tinkerer will appear bound, but – when you interact with him – he’ll become free. He will then move to an empty, NPC-appropriate house, where his shop will become available. The Tinkerer’s Workshop is part of this shop.

Combining Items

Once the Goblin Tinkerer has moved into your town and you’ve purchased and placed the Tinkerer’s Workshop, combining your items is pretty straightforward – so long as you have the correct recipes.

Simply open your inventory and go to the crafting menu. You must stand next to the Tinkerer’s Workshop to see its recipes in the crafting menu. Then, all you have to do is click on the item you wish to craft by combining items. 

Note that the items you’re going to combine must be in your inventory. Doing so will combine the items into one item. This item will have a random prefix. It’s worth noting that the prefix is completely random. 

That is to say; it’s not affected by the combined items’ individual prefixes. The Goblin Tinkerer can reforge these items if you’re unhappy with the prefix.

Keep in mind that late-game Tinkerer’s Workshop items have some of the most complicated crafting trees in Terraria, so getting them can be a challenge. However, it’s entirely worth doing to free up a few accessory slots.


Now that you know how to combine items in Terraria, you’ll be able to maximize your accessory space while benefitting from multiple items’ effects. Remember that you must defeat a Goblin Army to be able to get the Goblin Tinkerer – the NPC that sells Tinkerer’s Workshops.
