D2R LOCAL SAVE
Preparing your local rune inventory and tools.
A gem's type and quality determine its bonus. Weapon, armor/helm and shield effects differ. Three gems of the same type and quality upgrade to one of the next quality; perfect gems cannot be upgraded further. Keep the lower qualities needed by your planned rune upgrades, and select the exact gem when removing materials.
