Fusion pets still needed
Counts how many matching pets you still need for a fusion batch. The default of 5 matches the commonly reported steps from Common through Legendary. Change the pets-per-fusion number to 3 for Prodigious into Ascended and for Ascended into Mythical. These defaults are community ratios, not an official drop rate. If the live fusion preview shows a different number, use the preview.
Required total = materials per upgrade × number of upgrades. Missing = max(required total − materials already owned, 0).
Use 5 for Common to Uncommon, Uncommon to Rare, Rare to Epic, Epic to Legendary, and Legendary to Prodigious. Switch to 3 for the same Prodigious into one Ascended, and for the same Ascended into one Mythical. The form does not know your backpack and does not apply Shiny, Metallic, Giant, or Shiny Giant skins.
