How this calculator works
Refining here means producing metals and elemental stones from raw materials. Job level, DEX, LUK and the corresponding refining skill affect success. Iron has a 40-point base bonus, Steel 30, and elemental stones 10; each skill level adds 5 points. Attempts also receive a random 0.1–10 point bonus. Star Crumbs succeed at 100% once the skill requirement is met.
Each attempt consumes one Mini Furnace in addition to the recipe ingredients. Weapon production rates and the Baby job penalty do not apply to these recipes.
