The alchemist brews buff flasks from herbs and boss materials; the jeweler combines gems into the next tier. Equipment upgrades at the blacksmith use the rarity recipes at the bottom, multiplied by the upgrade level squared; the upgrade calculator adds them up.

Blacksmith upgrades
Base costs cover the jump from +0 to +1, with each push toward +n scaling quadratically at n² times the initial resources. Upgrades at +11 and +12 swap to a distinct recipe, requiring double the materials for the +12 attempt. For Rare, Legendary, and Divine gear, the +9 and +10 milestones also demand a single slot-matching boss material.
