Ultimate Umamusume Legacy Guide (2025 Global Edition)
Boost your Umamusume legacy results, farm those 9-star blue sparks, and hit Distance S in fewer runs.
1. Why you must master the Umamusume legacy system
"Breeding" is the game's hidden power-curve: every time you clear a 48-week training run, the finished horse girl is copied into your Hall of Fame, generating sparks (also called legacy factors). On the very next run you pick two of those Hall-of-Famers as parents, instantly gaining free stats, distance/terrain aptitude, and two mid-game "Inspiration" bursts. A strong parent pool therefore snowballs each new trainee's ceiling far more than any single Support Card pull. (Veteran players still refer to this as inheritance, so you'll see both terms online.)
2. Core terminology
| Term | What it means in-game | SEO tip |
|---|---|---|
| Legacy spark / factor | The ★-rated badges a horse generates at the end of training (colors: Blue, Pink, Green, White). | "Umamusume legacy spark", "Umamusume legacy factor" |
| Blue spark | Raw stats (Speed, Stamina, Power, Guts, Wisdom). Up to ★★★ per stat. | "9 star blue" |
| Pink spark | Aptitude (Distance / Track / Strategy). ★★★ lifts that aptitude to S. | "Distance S pink factor" |
| Compatibility | Hidden score between child ↔ parents; higher = more sparks fire during Inspirations. | "Umamusume legacy compatibility" |
| Legacy loop | Recycling a fixed set of high-spark parents to snowball every generation (older guides call this the inheritance loop). | "Umamusume legacy loop" |
3. Step-by-step legacy workflow
- Choose your goal - Decide the event meta first (e.g., July Champion Meeting = 2400 m Turf Mid-distance).
- Borrow a "god parent" - Add a friend with 9★ blue + 3★ pink (target distance). You can borrow them three times per day.
- Train your own complementary parent
- Push one stat beyond 1,100 to raise its blue-spark odds.
- Win races that match your meta distance to pump compatibility.
- Start the run
- Game instantly grants the Opening Legacy: +15 ~ +63 raw stats + pink aptitude rolls.
- Inspiration 1 fires at Turn 9; Inspiration 2 at Turn 31—more sparks = bigger boosts.
- Finish, review sparks, repeat - Promote any newly minted 3★ blue / 3★ pink parents into your loop and rinse-and-repeat.
4. Spark maths in plain English
| Spark tier | Blue stat gain | Example payoff |
|---|---|---|
| ★ | +5 | One extra Training tap |
| ★★ | +11 | Saves a full low-tier Training |
| ★★★ | +21 | ≈ Two rainbow Trainings |
Maxing six blue slots to ★★★ (the community's fabled "9-star-blue" = 3×3) dumps ~160 free stats before you even press your first Training button, then usually another 200+ across two Inspirations.
5. Cracking legacy compatibility
The game only shows △ / 〇 / ◎, but each pairing hides a numeric score (0–84).
- Shared distance, surface and strategy give the biggest chunks.
- Winning the same G1 races as your parents/grandparents adds +1 each time.
- Target 60+ (◎) to ensure both Inspirations pop.

6. The legacy loop template
- Borrow God Parent A (9★ blue 3★ pink).
- Partner them with Your Parent B (aim 3★ blue in your meta stat).
- Train Child 1 → becomes your new Parent B′ with more sparks.
- Swap B′ in, borrow God Parent A again → Train Child 2.
- Repeat until both parent slots are 3★ blue + 3★ pink. Your loop is now self-sustaining.
7. Common mistakes & quick fixes
| Mistake | Fix |
|---|---|
| Only looking at horse rank | Sparks ignore letter rank; focus on raw stat thresholds. |
| Mixing too many parents | Stick to 2–4 core parents for consistent compatibility. |
| Ignoring Pink sparks | Distance S ≈ +90 Speed in race maths—never skip it. |
| Hoarding unfinished parents | Retire low-spark ones; they only dilute your loop. |
8. FAQ in 30 seconds
-
Q: Can I get multiple copies of a spark?
A: Yes—both parents can contribute the same stat or distance spark, stacking the odds. -
Q: Does Support Card quality matter for sparks?
A: Indirectly. Higher Training power = higher final stats = higher chance of ★★★ blue. -
Q: What about the new Make a New Track green sparks?
A: They're bonus stats during Inspired turns; nice but never replace blue/pink priorities.
Key takeaways
- The Umamusume legacy system is the single biggest non-gacha power spike.
- Aim for 9-star blue + 3-star pink distance parents and lock them into a legacy loop.
- High legacy compatibility (◎) guarantees your double Inspiration payout, slashing stat-grind time.
Master these three levers and you'll hit Champion-Meeting podiums even with a budget Support-Card deck. Happy breeding, and may every run bless you with full-red sparks!
