If you’ve ever struggled to beat a tough boss like the Moon Lord or survive the brutal Hardmode desert biome, you might have missed one of the most powerful upgrades available in the game that doesn’t require any rare loot drops or complex crafting. Learning how to reforge Terraria items can turn even a decent mid-tier weapon or accessory into a game-changing tool that fits your exact playstyle, whether you’re a tanky melee main or a squishy summoner who prefers to fight from a distance. I’ve spent hundreds of hours testing different reforges across all four classes in classic, expert, and master mode playthroughs, and I’m breaking down exactly what you need to know to skip the wasted gold and get the bonuses you want on your first few tries.
Key Pre-Requisites Before You Start Reforging
Before you even think about reforging your favorite sword or accessory, there are a few boxes you need to tick first. You can only reforge items once you’ve rescued the Goblin Tinkerer NPC, which doesn’t happen until you’ve defeated at least one Goblin Army invasion. These invasions spawn randomly once you have at least 200 HP and 3 NPCs living in your world, or you can trigger one manually with a Goblin Battle Standard crafted from 10 tattered cloth and 5 wood at a loom. Once the invasion is defeated, you can find the Goblin Tinkerer tied up in the Underground Cavern layer, usually near areas with granite or marble biomes. Right-click him to free him, and he’ll move into any valid empty house you have available.
You’ll also need a decent stock of gold before you start rolling for modifiers. Each reforge costs 33% of the item’s base sell value, which adds up fast for endgame gear. For example, reforging a endgame weapon like the Terra Blade costs around 7 gold per roll, so if you need 10 tries to get the modifier you want, that’s 70 gold gone immediately. You can’t reforge quest items, master mode exclusive relics, or items with no modifiers, so don’t waste time trying to reforge things like the Angler’s fishing quest rewards or your cosmetic vanity items. They won’t show up in the reforge slot anyway, but it’s good to know ahead of time so you don’t get frustrated.
How to Reforge Terraria Items in 3 Quick Steps
Once you have the Goblin Tinkerer settled in a valid house and enough gold saved up, the actual process is straightforward, even for total beginners. Follow these steps every time:
- Open your inventory and right-click the Goblin Tinkerer to pull up his shop interface. Look for the small reforge slot at the top right of the shop window.
- Drag the item you want to reforge from your inventory into the empty reforge slot. The cost of one reforge roll will display below the slot, so double-check you have enough gold to cover multiple attempts if needed.
- Click the reforge button below the slot to roll a random new modifier for your item. If you don’t like the result, you can click the button again to re-roll, as long as you have enough gold left to cover the cost.
That’s really all there is to the core process, but there are a few common mistakes new players make here that cost them tons of gold. There’s no way to lock in a good modifier while you roll, so stop as soon as you get the bonus you want. I learned this the hard way a few years back, when I was reforging a Celestial Shell for my melee playthrough. I rolled the Warding modifier, which gives +4 defense, on my second try, but I got greedy and kept rolling to see if I could get Lucky for extra crit chance. I ended up wasting 62 gold before I got Warding again, and I didn’t even end up with the Lucky modifier anyway. If you’re playing for fun and not trying to min-max for a speedrun, any modifier that gives a positive boost to your class’s core stats is good enough to keep.
How to Pick the Best Reforge for Your Playstyle
Not all reforges are created equal, and what counts as a “good” modifier depends entirely on what class you’re playing and how you like to approach combat. For melee players who spend most of their time up close to bosses, high damage and knockback resistance are the most important stats to look for. The Legendary modifier is the best for most melee weapons, as it gives +15% damage, +10% speed, +10% knockback, and +5% crit chance. For accessories, Warding is perfect if you struggle with survivability, while Menacing is better if you want to stack as much damage as possible.
Ranged players should prioritize crit chance and attack speed, so the Unreal modifier is the top pick for most guns and bows. Magic users want to look for the Mythical modifier for their weapons, which cuts mana cost by 10% on top of boosting damage and crit chance, so you don’t have to chug mana potions every 10 seconds during boss fights. Summoners have a slightly different priority: look for the Ruthless modifier for your summon weapons, as it boosts minion damage the most, and avoid any modifiers that lower minion knockback or damage. Avoid reforges that give penalties to your class’s core stat, no matter how good the other bonuses look. If you’re a magic user, a reforge that gives +10% damage but -20% mana is never worth it, because you’ll run out of mana halfway through every fight.
Casual players don’t need to stress about chasing the absolute best modifier for every item, either. A +5% damage modifier on your weapon is enough to get you through most of Hardmode, and you can always reforge it again later when you have more gold to spare. I usually only go for the top tier modifiers on my endgame gear, once I’ve beaten all the mechanical bosses and have a steady stream of gold from farming pirate invasions.
Pro Tips to Cut Down Reforging Costs
Reforging can get really expensive really fast, but there are a few simple tricks you can use to cut down your costs by up to 30% with barely any extra effort. The first and most impactful one is to get the Discount Card, which drops from pirates during Pirate Invasions. It’s a rare drop, but it cuts all NPC prices by 20% permanently as long as you have it in your inventory, and that discount applies to reforging costs too. I usually farm one pirate invasion as soon as I enter Hardmode just to get this card, it saves me thousands of gold over the course of a full playthrough.
Place the Goblin Tinkerer in the Underground Cavern layer to get his preferred housing bonus, which lowers his prices by another 10%. This stacks with the Discount Card, so you get a total of 30% off every reforge roll. You don’t have to keep him down there forever, just move him to an underground house whenever you plan to do a lot of reforging, then move him back up to your main base later if you want. Another easy tip is to sell extra loot you don’t need directly to the Goblin Tinkerer when you’re reforging, so you don’t have to run back and forth to another NPC’s shop to get more gold mid-session.
Only reforge items you plan to use for at least 10 hours of gameplay, or endgame items that you’ll keep for your full playthrough. There’s no point in spending 20 gold reforging a pre-Hardmode sword that you’re going to replace as soon as you beat the Wall of Flesh. I usually skip reforging entirely until I get to Hardmode, except for my pickaxe and my main accessory, because I go through weapons so fast in the early game that it’s never worth the cost. If you’re playing in multiplayer, you can also pool gold with your friends to split the cost of reforging shared items, or take turns rolling for modifiers for each other to cut down on individual costs. My friend group does this all the time, and it cuts our total reforging costs in half for most playthroughs.
Reforging is one of the most underrated quality of life mechanics in Terraria, and it doesn’t take much effort to get huge boosts to your damage, survivability, or utility for every part of your playthrough. You don’t need to be a min-max expert or have thousands of gold saved up to benefit from it either, even a small positive modifier on your main weapon will make a noticeable difference in how fast you clear enemies and bosses. Once you get the hang of how to reforge Terraria items to match your class and playstyle, you’ll find that even the most annoying boss fights and dangerous biomes feel far more manageable. Take it slow, don’t get greedy with rolls, and you’ll be crushing Hardmode in no time.
