RockFruit Umamusume Update Guide: New Island, Dungeon, Crafting, Specs, and More!

The latest RockFruit update introduces a collaboration themed around Umamusume, bringing several new gameplay systems, weapons, and locations to explore. While many players expected characters like Kratos or Ainz based on previous teasers, the update instead focuses on new Umamusume-inspired content, including a crafting system, dungeon, Horse Island, and three new specs. This guide covers everything added in the update, including how the new dungeon works, what the crafting system offers, and whether the new specs are worth unlocking.

New Crafting Table on Starter Island

One of the biggest additions is the Crafting Table, which can be found on Starter Island. This system allows players to craft various items by collecting the required materials throughout the game. However, crafting isn’t guaranteed to succeed.

Every recipe has a percentage-based success rate, meaning there’s always a chance your crafting attempt will fail. While there is a mechanic that can eventually guarantee success after repeated attempts, players still need to deal with RNG before reaching that point.

Because crafting materials require time and effort to obtain, this success system makes crafting much more resource-intensive than many players expected.

• Located on Starter Island.
• Uses collected crafting materials.
• Every recipe has a success percentage.
• Failed attempts consume resources.
• Guaranteed success becomes available after enough attempts.

New Dungeon and Dungeon Shop

Another major feature is the brand-new Dungeon System, which is also accessible from Starter Island. Players can enter dungeons to battle through multiple waves of enemies while earning exclusive dungeon rewards. Besides item drops, completing dungeon runs also awards Dungeon Points, which can be spent in the new Dungeon Shop. This provides two different reward paths:

• Random item drops from dungeon clears.
• Dungeon Points used to purchase specific rewards.

Dungeon Features

• 15 combat waves.
• Auto Skip option available.
• Earn Dungeon Points after completing runs.
• Obtain exclusive dungeon loot.
• Supports up to 12 players.

To start a dungeon, someone in the party must use a Dungeon Orb, allowing the group to host the instance.

Explore the New Horse Island

The update also introduces Horse Island, a brand-new area themed around the Umamusume collaboration. Players will find:

• New quests.
• Event-related enemies.
• Exclusive crafting materials.
• Resources required for the newest specs.

Since many of the new recipes require materials obtained here, Horse Island quickly becomes one of the most important farming locations introduced in this update.

Event NPCs and New Spec Requirements

All NPCs responsible for unlocking the new Umamusume-themed specs can be found on the Event Island. Each spec generally requires three things before it can be unlocked:

• The corresponding Umamusume race.
• Materials collected from the Event Island.
• A specific crafted item made through the new crafting system.

Because of these requirements, players will likely need to spend time farming both Horse Island and the new dungeon before unlocking every spec.

Piccolo Boss Now Drops Dragon Balls

Another useful addition is the Piccolo Boss, which now appears on Shadow Island. Defeating this boss gives players another opportunity to obtain Dragon Balls, making it a worthwhile encounter for anyone farming Dragon Ball-related progression. This boss adds another repeatable activity for players looking to collect rare items outside of the new event content.

Auto Summon Is Finally Available

One of the most welcomed quality-of-life improvements in the update is the addition of Auto Summon. Instead of manually repeating summons over and over, players can now automate the process, making it much easier to spend large amounts of currency while chasing rare rewards. For many players, this is easily the best non-combat feature introduced in the update because it saves both time and repetitive clicking.

Dungeon Difficulty

Although the dungeon includes 15 waves of enemies, it isn’t particularly difficult. Enemy health doesn’t appear especially high, and experienced players should be able to clear runs without much trouble. It’s currently an efficient farming activity thanks to the relatively low difficulty combined with valuable rewards. Whether enemy scaling changes based on party size is still unclear, but at launch the dungeon feels accessible even for smaller groups.

Mambo Spec Overview

Mambo is one of the three new Umamusume-inspired specs introduced in the update. Its abilities lean toward a more humorous or “meme” design, but the spec performs better than its appearance might suggest. Even without additional upgrades such as Magic Books, Mambo delivers respectable base damage and remains capable during regular PvE content.

Mambo Strengths

• Good base damage.
• Fun ability animations.
• Better performance than expected.
• Viable for general gameplay.

Hachimi Spec Overview

Hachimi offers a more balanced toolkit compared to Mambo. One of its standout features is a healing ability, giving players additional survivability during longer fights. Its Z skill activates quickly and can be used frequently, making the overall combat flow feel faster than Mambo’s. When comparing raw damage, Hachimi appears to outperform Mambo while also providing useful utility through healing.

Hachimi Highlights

• Includes a healing move.
• Fast Z skill.
• Strong overall damage.
• Solid balance between offense and survivability.

Agnes Tachyon Spec Overview

Among all three additions, Agnes Tachyon stands out as the strongest new spec in the update. Unlike the more comedic designs of the other two specs, Agnes Tachyon features a complete and polished moveset with impressive visual effects and excellent damage output.

One unique mechanic is the interaction between its abilities. The F skill can only be activated after using the Z skill, creating a combo-based playstyle. The F move also sacrifices some of the user’s health in exchange for extremely high damage, giving experienced players a powerful risk-versus-reward option. If needed, the attack can be cancelled early by pressing the skill key again.

• Highest damage among the new specs.
• Excellent visual effects.
• Combo-based abilities.
• Powerful health-sacrifice attack.
• Can cancel the F skill before it finishes.

For players looking for the strongest combat option from this update, Agnes Tachyon is easily the top choice.

Best Features Added in the Update

Several additions stand out as major improvements to the overall gameplay experience. The most notable features include:

• Auto Summon for faster rolling.
• New multiplayer dungeon.
• Dungeon Point reward system.
• Horse Island with exclusive materials.
• Three new Umamusume specs.
• Additional Dragon Ball farming through the Piccolo Boss.

These additions give players more endgame activities and multiple ways to earn new rewards.

While the update introduces plenty of content, the new crafting system has received mixed reactions. The primary complaint is its reliance on percentage-based crafting success. Since obtaining crafting materials already depends heavily on RNG and farming, adding another layer of chance during crafting can make progression feel unnecessarily slow. Players hoping for a straightforward crafting system may find this mechanic frustrating, especially when rare materials are consumed on failed attempts.

The Umamusume update adds a healthy amount of new content to RockFruit, including a new dungeon, Horse Island, fresh progression systems, and three unique specs. Auto Summon is one of the best quality-of-life improvements introduced so far, while the dungeon provides another rewarding activity for farming exclusive items and Dungeon Points.

Among the new specs, Agnes Tachyon clearly stands out thanks to its powerful combo mechanics and impressive damage potential. Meanwhile, the crafting system is likely to be the most divisive addition because of its percentage-based success mechanic. Despite that drawback, the update still offers plenty of new content for players looking to explore the latest features and expand their collection.
