The Forge Crafting Calculator

This Forge Crafting Calculator helps you predict what you can craft in Roblox The Forge before you actually forge it. Select your ores to see the most likely weapons or armor, the final multiplier, and any traits that will transfer. Results are probability based and meant to help you plan better crafts.

How This Forge Crafting Calculator Works

This tool doesn’t guess or promise a guaranteed result. It simply follows the same rules The Forge uses and shows you the most likely outcomes based on the ores you choose.

1. You select the ores

First, pick at least 3 ores. You can choose up to 4 different ore types, and you can add as many pieces of each as you want.

The total number of ores you use is very important. It decides what kind of weapon or armor the forge can roll, not how strong it is.

2. Total ore count decides what you can craft

The Forge does not look at ore type to decide weapon or armor size. It only looks at how many total ores you put in.

  • Fewer ores → smaller weapons like Daggers or Straight Swords
  • More ores → larger weapons like Katanas, Great Swords, or Colossal weapons
  • In Armor mode, higher ore counts shift chances from Light to Medium and Heavy armor

Our calculator uses the same known crafting thresholds and turns them into probability ranges, not guarantees.

3. Weapon and armor chances are probabilities

When you forge in the real game, the result is random.

Instead of showing one result, this tool shows:

  • Which weapon or armor classes are possible
  • How likely each class is
  • Which specific items exist inside each class and their relative chances

This is why you’ll see percentages instead of a single result.

4. Multiplier decides how strong the item is

Ore quality affects strength, not item type.

Each ore has a multiplier value.
The final multiplier is the average of all ore multipliers you selected.

Formula used:

Final Multiplier =
(sum of each ore multiplier × its quantity) ÷ (total ore count)

This multiplier scales the base stats of the weapon or armor you roll.

5. Traits come from ore composition

Some ores have special traits like burn, explosion, extra defense, or movement speed.

Traits activate based on percentage of that ore in your mix:

  • Less than 10% → trait does not activate
  • 10% or more → trait activates and transfers to the item

If multiple trait ores reach this threshold, all of them activate together.

The calculator simply shows which traits will apply. It does not simulate combat damage or skill effects.

6. Weapons and armor are rolled in two steps

The Forge rolls results in layers:

  1. It rolls the item class (weapon type or armor weight) based on total ores
  2. It rolls the specific item inside that class using fixed chance weights

This tool shows both steps clearly so you can understand where your odds come from.

7. This is a planning tool, not a guarantee

The Forge uses hidden RNG. There is no public official formula.

This calculator uses known crafting rules and community-tested data to give you realistic estimates, so you can plan smarter before spending rare ores.

Results may differ slightly from the game, but the logic stays true to how forging actually works.

FAQ

Q.

Is this Forge Crafting Calculator 100% accurate?

No. The Forge uses hidden RNG and does not publish exact crafting formulas. This tool shows probability-based estimates using known crafting rules and community-tested data.

Q.

Why do my results look different from other Forge calculators?

There is no official crafting formula. Different calculators use slightly different assumptions or models, which is why results can vary a bit.

Q.

Does ore type decide which weapon or armor I get?

No. Ore type does not decide the weapon or armor class. Only the total number of ores affects what type of item the forge can roll.

Q.

What does the multiplier actually do?

The multiplier scales the final stats of the item, such as weapon damage or armor health. It does not affect which weapon or armor you roll.

Q.

How is the final multiplier calculated?

It is the average of all ore multipliers used. The formula is: (sum of ore multiplier × quantity) ÷ total ore count.

Q.

How do traits activate in this calculator?

A trait activates when its ore makes up at least 10% of the total ore mix. Multiple traits can activate at the same time if they meet this threshold.

Q.

Can I guarantee a specific weapon or armor using this tool?

No. The forge is random. This calculator only shows what is most likely, not guaranteed outcomes.

Q.

Why do some weapons or armor pieces show very low chances?

Some items are intentionally rare in the game. Even if a class has a high chance, certain items inside that class can still be rare.

Q.

Does adding more ores always make the result better?

Not always. More ores unlock larger weapons or heavier armor, but they can also reduce the chance of smaller items you might want.

Q.

Does this calculator account for Island 1 or Island 2 requirements?

No. The tool focuses only on crafting probabilities. Some armor variants may require later game progression, but that is not simulated here.

Q.

Why can I only select up to four ore types?

This limit keeps the calculator simple and reflects how most players actually mix ores when forging items in The Forge.

Q.

Is this tool affiliated with the developers of The Forge?

No. This is an independent fan-made calculator built to help players plan their crafts more effectively.
