"At the end of a Career, every normal rarity skill, victorious G1 race, and the Career itself have 20% chance of generating a white spark. ◎ skills have 25% chance, and rare (gold) skills have 40%.

The chance for 1 is 50%, for 2 45%, and for 3 5%. The chances for 2 and 3 increase if the umamusume is at least SS rank."
