Ultimate Inheritance Guide

Unlock the hidden potential of your Uma Musume by mastering the complex mechanics of inheritance events.

What is Inheritance?

Inheritance is the core mechanic that allows you to transfer stats, skills, and aptitudes from previous generations of trained girls (Parents and Grandparents) to your new trainee. It occurs three times during a training run:

  • 1 Start of Training: Initial stat boost and starting skills.
  • 2 Classic Year (April): The first inheritance event.
  • 3 Senior Year (April): The second inheritance event.

Understanding Factors (Traits)

🟦 Blue
Raw Stats

Speed, Stamina, Power, Guts, Wisdom. Always inherits.

🟥 Red
Aptitude

Surface, Distance, Strategy upgrades (e.g. A → S).

🟩 Green
Unique Skills

Inherit parents' unique ultimate skills.

White Factors provide normal skill hints and small stat bonuses. The higher the star rating (1★ to 3★) of any factor, the higher the chance and magnitude of inheritance.

💡 Pro Strategy

Always aim for 3★ Blue Factors on your parents. A parent with 3★ Speed will transfer significantly more stats than a 1★ parent. The star rating is determined by the stat value at the end of their training run (SS+ rank gives the best chance for 3★).
