Methodology

Average multiplier

Average multiplier is calculated as the weighted mean of selected ore multipliers. For each ore, the calculator multiplies quantity by the local multiplier value, 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 so the result remains deterministic.

Probability status

Craft tiers are grouped as starter, standard, refined, and high-tier planning buckets. Exact probability splits are not presented as guaranteed odds unless the table has been checked for the current rules version.

Trait labels

Trait shares are calculated by dividing the quantity of ores carrying that trait by total selected ores. Labels are below 10%, near 10%, 10% active, near 30%, and 30% active.

Current data

Rules/data version May 2026. Review policy: after meaningful game updates, formula reports, or player feedback. Ore multipliers and category buckets are transparent planning data. Reviews are tied to meaningful game updates, formula reports, and player feedback rather than a daily calendar.

Ore names, rarity, area, and multipliers are source checked against public community tables. Trait effect text and exact craft probability splits are tracked separately because those fields are easier to misread and can change with balance updates.

• Public ore table cross-check: Used for ore names, rarity, area, and multiplier values in the local table.
• The Forge Wiki calculator competitor check: Used as a cross-check for the starter Stone + Copper + Iron average.
• Fandom ore pages: Used as a secondary public reference when available; individual pages can lag behind community calculator data.
• Manual formula review: Average multiplier is calculated from selected ore quantities and ore multipliers.
