Understand your mix

Compare the likely item range, average multiplier, and each ore's share before you forge.

Average multiplier

Each ore contributes its multiplier times quantity. The total is divided by all selected ores.

Likely item range

Total ore count selects a likely item range. Exact output remains RNG-based, especially between optimal counts.

Trait thresholds

Each ore has its own 10% and 30% share thresholds. Different ores with the same trait stay separate.

The Forge calculator FAQ

Quick answers before you spend your ores.

How many ores can I use in The Forge?

A craft needs at least 3 total ores, and a mix can contain up to 4 different ore types. This planner caps inventory suggestions at 51 total ores for weapons and 45 for armor.

Does The Forge calculator predict the exact item?

No. Total ore count identifies a likely weapon or armor range, but the exact item remains RNG-based.

How is the ore multiplier calculated?

The planner multiplies each ore's multiplier by its quantity, adds those contributions, and divides by the total ore count.
