Refinery Grade Logic
Base rarity = higher rarity of parent A and parent B
Tier gap = absolute difference between parent rarities
Adjusted upgrade chance = base upgrade chance x tier gap modifier
Reduced upgrade chance is added back to the same-rarity outcome
The result keeps the same stone type and carries traits shaped by both parent GEMS.
Same as both parents.
Parent average with small variance.
Better color, clarity, and cut are favored.
The stronger parent sets the base tier, while refinement decides the next gemstone outcome.
Large rarity gaps reduce upgrade probability; gap 3 or higher cannot be refined.
Fee Rule
Refinery fee is calculated from the higher parent rarity: Common 20 STONX, Rare 60 STONX, Epic 200 STONX. Legendary is not refinable.
