Understanding the Uma Musume Inheritance System
What is Inheritance in Uma Musume Pretty Derby?
Inheritance determines how stats, skills, and aptitudes transfer from parent Uma Musume to offspring during breeding. The system uses a 6-member family tree: target character (child), 2 parents, 4 grandparents. Each ancestor contributes bonuses based on compatibility with the target.
Inheritance has 5 core components:
- 1. Surface Compatibility Racing surface (turf or dirt) must match. Matching surfaces earn +10 points per ancestor. Mismatches earn 0 points.
- 2. Distance Matching Each matching distance category adds +4 points. Versatile characters create more overlaps.
- 3. Strategy Synergy Matching strategies (leader/runner/etc) add +3 points per match.
- 4. Grade Bonuses Parents and grandparents sharing the same G1/G2/G3 victories earn +1 bonus per grade tier.
◎ Maximizing Your Inheritance Score
Aim for the 120+ Score (◎ Rating)
This "Excellent" rating is a game-changer. It effectively doubles your inheritance rates and unlocks 9 factor slots instead of the standard 7.
