Cygames’ Umamusume Pretty Derby has some pretty cool mechanics that make the game a lot more fun, like career training, raising potentials, leveling up characters, and more. One of the most important (and probably most confusing) systems in the game is the Spark mechanic.

You’ll notice it during career playthroughs when your Umamusume suddenly gets hit with a burst of inspiration, called a Spark, and gains a few stat boosts afterward. If you're confused about how it works, this guide will explain what Sparks are and how to make the most of them in Umamusume Pretty Derby.

What are Sparks in Umamusume Pretty Derby?

how do sparks work in umamusume pretty derby

In Umamusume Pretty Derby, Sparks are the inherited stats, aptitudes, and skills your character gets from her Legacy Team (also known as parents or Veteran Umamusume). Simply put, every horsegirl begins with a base set of attributes: Speed, Stamina, Power, Guts, and Wit. You’ll build on these during her career to turn her into a top-tier racer, but Sparks give her a nice head start by adding bonus stats on top.

That means, instead of starting with 100 Speed, a horsegirl might enter the academy with 120, making her stronger before training even begins. During her journey, she can also get surprise sparks of inspiration from her Legacy horsegirls, helping boost her attributes even more and giving her a solid lead in career races.

As such, she'll also get better aptitudes for things like Track, Distance, and Running Style, and even pick up some handy skills from her legacy racers, both at the start and while training.

How Do Sparks Work in Umamusume Pretty Derby?

Sparks are tied to your horsegirl’s Legacy Umamusume; basically the two parent racers you pick before starting her career. The Sparks they pass down show up in four colors:

  • Blue Sparks = Speed, Stamina, Power, etc.
  • Pink Sparks = Track Type, Distance, and Running Style
  • Green Sparks = Unique Skill
  • White Sparks = Regular skills and race skills

While you can see most of the Sparks directly on a parent’s legacy profile, all four types only show up in the sidebar once you confirm the Veteran Umamusume. You can switch them out afterward if you change your mind.

To get the improved stats, aptitudes, and skills you want, it helps to be smart with Legacy Team picks. Let’s say you want your trainee to start off with more Stamina and do well in long-distance races, then go for two veteran racers who have Stamina as a Blue Spark and Long as a Pink Spark, ideally with three stars on both. Do the same for Green and White Sparks if you’re aiming for a certain skill.

Since Legacy horsegirls also have their own parents, it's even better if those grandparents share the same focus stats or skills with three stars. That way, your trainee has an even better shot at getting great Sparks.

How to Create The Best Legacy Team in Umamusume Pretty Derby

While Legacy Umamusumes with one or two stars on Sparks might still work, those with three stars give the most stat points and better traits or skills. So, ideally, those are the ones you want to use for your trainees.

In Umamusume Pretty Derby, Legacy horsegirls can either be created by completing the careers of your trainees or borrowed from other players. The best approach is to build your own Legacy Umamusumes with three-star Sparks in the areas you want. This way, you can reuse them anytime. That said, building perfect Legacy Umas isn’t easy since the Sparks (stats, aptitudes, and skills) they get after a career run are mostly based on luck. Still, there are ways to improve your chances.

  • Blue Sparks: If you want a three-star Blue Spark in a certain stat, aim to have 600+ points in that attribute by the end of the career. This gives you about a 6% chance. If you go over 1100 points, your odds jump to 10%.
  • Pink Sparks: These are based on your trainee’s final ranks. The game randomly picks from any A, S, or SS ranks she has and assigns stars. To increase your odds, use Legacy horsegirls who also have high ranks (A or better) in the areas you care about, like Long Distance or Dirt. That way, the trainee’s growth leans more in that direction.
  • Green Sparks: Green Sparks can only be passed down by characters who have unlocked three stars on their trainee profile. That means you need to spend Star Pieces and wrap up their Star Unlocks. The star rating here is mostly RNG, but having maxed-out unlocks and potential increases your likelihood.
  • White Sparks: To get specific skill Sparks, teach your trainee those skills during her training using Skill Points. If her Legacy parents have those same skills, your chances go up. For Race Skills, try to finish her career with some G1 wins. The more parents who have the skill, the higher the star rating of that Spark.
