Inheritance FAQ

What are Blue Factors?

Blue factors provide raw stat increases during inheritance events (Start of training, Year 2 April, Year 3 April). The stats given depend on the star rating (1★ to 3★).

How do I get 3★ Blue Factors?

It is purely RNG. However, to even have a chance at a 3★ factor for a specific stat (e.g., Speed), you must end the training run with that stat at **B rank** (600+) or higher. SS rank (1100+) does slightly increase the odds of 3★ factors appearing.

What is Compatibility (◎)?

Double Circle (◎) compatibility means your inheritance events will trigger more effectively, granting more stats and skills. It is calculated based on the relationships between the child and the two parents, as well as the parents' parents (grandparents). Winning the same G1 races also boosts compatibility.
