What Are Star Pieces in Umamusume

In Umamusume: Pretty Derby, beyond simply acquiring new characters, a core progression mechanic, typical of gacha games, involves obtaining duplicates to enhance your existing Umamusume's potential. This process relies on a crucial and rare currency known as Star Pieces. For beginner players, understanding the significance and usage of Star Pieces is vital for long-term character development.Here's a comprehensive guide to everything you need to know about Star Pieces in Umamusume: Pretty Derby.

What Are Star Pieces in Umamusume Pretty Derby?

Star Pieces are an exceptionally rare and valuable type of currency in Umamusume: Pretty Derby. Their primary purpose is to enhance the power and abilities of your Umamusume characters.Key characteristics of Star Pieces:
  • Source: They are mainly obtained by acquiring duplicate Umamusume characters through the game's gacha (Scout) feature. When you pull a character you already own, that duplicate is automatically converted into a certain number of Star Pieces specific to that character.
  • Character Exclusive: Star Pieces are exclusive to individual characters. This means if you get a duplicate of Mihono Bourbon, you will receive Star Pieces only for Mihono Bourbon. These cannot be used for any other character. This emphasizes the need to repeatedly pull specific characters to fully enhance them.
  • Alternative Acquisition: While duplicates are the primary source, you can also obtain Star Pieces through:
    • Goddess Statues Exchange: Goddess Statues are a rare currency often acquired from events or other high-tier rewards. You can exchange these statues for Star Pieces of specific characters, allowing you to target enhancements even if you don't pull duplicates.
    • In-game Events: Various limited-time events within the game may offer Star Pieces as rewards for participation or completion of event objectives.

Using Star Pieces in Umamusume Pretty Derby

The main utility of Star Pieces is for "Star Unlocking," a feature that allows you to increase the Star Level of your Uma Girl. Increasing a character's Star Level provides significant enhancements to their stats and abilities.

Here's how to use Star Pieces for Star Unlocking:

  • Navigate to Enhance Tab: From the main menu, go to the "Enhance" tab.
  • Select "Star Unlock" under Trainee: Within the Enhance menu, find and select the "Star Unlock" option, typically located under the "Trainee" section (which refers to your Umamusume characters).
  • Choose Your Umamusume: Select the Umamusume character whose Star Level you wish to increase.
  • Confirm Star Unlock: If you have enough of that character's specific Star Pieces, you can proceed with the Star Unlock.
  • Star Level Progression and Benefits:

    • Starting Star Levels:

      • R-rarity characters start at 1 Star.
      • SR characters start at 2 Stars.
      • SSR characters start at 3 Stars.
    • Required Star Pieces: Increasing Star Levels requires a considerable number of Star Pieces. The amount needed generally decreases for higher-rarity characters to reach their next Star Level, meaning SSRs might require fewer pieces per level than Rs or SRs, reflecting their higher base rarity.
    • Hidden Talent (Stat Bonuses): Each increase in Star Level provides a significant boost to the Umamusume's base stats (Speed, Power, Stamina, Wit, Guts). These are often referred to as"hidden talents" or "aptitude bonuses." These direct stat increases make your Umamusume inherently stronger, regardless of training.
    • Unique Skill Upgrades: Crucially, increasing Star Levels can unlock or upgrade a character's unique skill. Many unique skills have multiple tiers, with higher Star Levelsunlocking more powerful versions. This is a vital reason to Star Unlockyour favorite and strongest Umamusume.
    • Special Dress (at Star Level 3): Reaching Star Level 3 (for characters that start below 3-star) unlocks that character's special "private clothes" or "casual outfit" in their character model viewer. This is a cosmetic reward thatshowcases your dedication to the character. For SSR characters who start at 3 stars, they already have their special dress unlocked.
    • Gacha Star Levels: When you pull a new character from the gacha, they are referred to as 3-star, 2-star, or 1-star characters based on their base rarity. The "Star Unlock" process then takes them beyond their base rarity level, increasing their "talent" or "potential"stars. For example, a 3-star (SSR) character can be Star Unlocked to4-star, 5-star, and eventually 6-star, gaining more power with eachstep.

    Understanding and strategically using Star Pieces is key to building truly formidable Umamusume, allowing you to enhance your favorite characters beyondtheir base capabilities and unlock their full potential on the racetrack.
