How the planner reads a craft
The calculator keeps the formula visible: selected ores become a weighted multiplier, the largest material share becomes the main material, and trait progress is shown against the public 10% and 30% thresholds.
Average multiplier
Each ore contributes its multiplier times quantity. The total is divided by all selected ores.
Craft band
Weapon and armor outputs are grouped into planning bands until exact probability tables are checked again.
Trait thresholds
Trait shares show whether a material identity is below 10%, active at 10%, near 30%, or active at 30%.
Planner pages
Use the focused pages when you want a narrower view of the same local rules and ore table.
Weapon Calculator
Open the same calculator in weapon mode with short notes for craft-tier planning.
