How the calculator works
Formulas & sources
Ore count guides the item class. Your mix's average multiplier estimates its base stats.
Average multiplier
Average multiplier is calculated as the weighted mean of selected ore multipliers. For each ore, the calculator multiplies quantity by the listed multiplier, adds those values together, and divides by total ore count.
Main material
Main material is the selected ore with the highest quantity. If two ores tie, the higher multiplier is used as the tie-breaker.
Likely item range
Total ore count maps to a broad weapon or armor range built from published minimum and optimal counts. Adjacent classes overlap, so the label is guidance rather than a guaranteed result. Confirm the in-game preview before forging.
Trait labels
Each ore's share is its own quantity divided by total selected ores. Two ores with the same trait label are kept separate: 3 Fireite and 3 Kyubite in a 20-ore recipe each contribute 15%, not one 30% Burn threshold. Labels mark the 10% and 30% ore-share thresholds only. They do not establish equipment compatibility, effect strength, or stacking.
Ore values & sources
This calculator includes 69 ores, last checked Aug 4, 2026. It does not cover every ore in the game. “Guide-listed” entries use community references and have not been tested in game. Estimated entries need extra care.
Names, rarity, areas, and multipliers come from community guides. Item ranges use published ore counts; the calculator does not predict exact drop chances.
