Rather noob’s question, but I cannot quite understand how this “percentage boosting” works. For example, Winged Bison’s “Migrate” says: “Transform all Purple Gems to Red. 40% chance to summon a Winged Bison, boosted by Gems transformed” (and a ratio given: “x2”). Am I right that each purple gem transformed adds 2% to the basic 40%? So if 14 purple gems were transformed, I’ll get +28% for them, and 68% chance to summon Winged Bison?
