Transparent formulas
Methodology
Forge Craft Planner is built around visible assumptions. The calculator gives planning guidance and labels areas where exact probability splits are not shown.
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 when the planner is using bands.
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
July 2026 planning review. Reviewed after meaningful game updates, formula reports, or player feedback. Ore multipliers and category buckets are transparent planning data. The planner now uses the four ore type limit shown by current community calculators and keeps exact probability splits labeled as planning guidance.
Ore names, rarity, area, and multipliers are checked against public community tables. Trait effect text and exact craft probability splits are treated 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.
- Community calculator rule comparison: Used to confirm that current community calculators present forge mixes as three or more ores with up to four ore types.
