The Forging Process
The Forging mini-game consists of three different steps, and The Forge Calculator helps you understand each phase before you spend your ores.
The First Step: Heating the Crucible
The First Step of the forging process in The Forge has players choosing which, and how many Ores they'll add to the crucible to be smelted down.
At the bottom of the Forge/Select Ores menu, players can choose if they wish to craft a Weapon or an Armor. The amount of Ores added directly correlates to which type of Weapon or Armor can be crafted from them.
A higher number of Ores will yield greater chances of crafting larger Weapons and heavier Armor.
After adding Ores to the crucible, players will then need to smelt them by completing the first mini-game.
💡 Tip: The first mini-game can be completed by rapidly moving the forge's bellows, located on the left-hand side of the screen and indicated by a green arrow. This will cause the forge to produce more heat, smelting the ores in the process.
The Second Step: Pouring the Melted Ores into a Mold
The Second Step of the forging process will require a bit of balance on the player's part.
You will need to pour out the smelted Ores into a mold, which will later be broken apart to start the third and final step.
To complete the Second Step, players will need to keep their eyes on the black bar located on the right side of their screen.
💡 Tip: To perfectly pour the smelted Ores into a mold, and to quickly fill the progress bar at the bottom, you will need to balance the White Mark inside the Yellow Bar at all times. This can be done by holding down and releasing the Left Mouse Button. Holding it down will cause the White Mark to rise towards the top, and releasing it will cause it to plummet downward.
The Pouring Step
Hold to raise the white marker, release to let it drop. Track the moving golden zone and stay inside it for 6 seconds.
The Third Step: Using the Anvil to Hammer the Product into Shape
The Third, and final step, of the forging process has players breaking apart mold filled with smelted down ores, to uncover a rough shape of the Weapon or Armor they mean to craft.
To complete the crafting process, you will need to further refine it by hammering it at the anvil. Breaking the mold will start the mini-game.
To complete it, players will need to click on the circles appearing around the Weapon or Armor they're crafting.
💡 Tip: Timing is also of the essence here, as clicking on the circle just as it reaches the inner edge will prompt it to be Perfect. This greatly affects the quality of the crafted Weapon or Armor.
Afterwards, the product will be quenched in a bucket of water. This final step completes the crafting process in The Forge.
Players can choose to sell their crafted products, or equip and use them from their inventory.
The Third Step
Time your hammer strikes. A thick outer ring shrinks toward a solid inner circle — click when they almost meet.
Tap to start. Click when the shrinking outer ring reaches the solid inner circle.

What does this tool do?
Think of The Forge Calculator as your dedicated crafting simulator. It helps you calculate success rates and preview stats for The Forge on Roblox, so you can optimize your ore builds before heading to the anvil.
Can I trust the percentages?
Absolutely. The Forge Calculator uses formulas based on the game's mechanics to provide highly accurate simulations. While RNG is always a factor, our math is based on the actual game logic.
Can I simulate armor crafting too?
Yes! Whether you are forging a sword or a chestplate, just select the appropriate category at the top. The Forge Calculator adjusts the stat predictions automatically for each item type.
How many ores can I use at once?
You are free to mix up to 4 different ore varieties. There's no cap on the total amount of ore, so feel free to test out massive bulk recipes directly inside The Forge Calculator.
What does the "Trait %" mean?
This tells you the purity of your item. A key rule to remember: An ore type needs to represent at least 10% of your total mix to activate its special trait on the finished item, and The Forge Calculator highlights this for you.
Do I have to pay to use this?
No way. The Forge Calculator is completely free for everyone. Our goal is simply to help the community craft better gear.
Is it up to date?
Yes, we monitor The Forge closely. As soon as the developers drop a new update or change ore stats, we work to update The Forge Calculator immediately.
How do I save my build?
There isn't a "Save" button right now, but re-entering your ores is super fast inside The Forge Calculator. For now, the best way to save a complex recipe is to just screenshot the result!
