Umamusume Hint Book Complete Guide

In the latest update of Uma Musume, Hint Books have been officially launched as a new rare resource, leaving many players confused about their functions, acquisition methods, and usage strategies. As key items to increase the hint levels of UMAs’ inherent skills, Hint Books can significantly enhance combat power. However, due to limited acquisition channels and high upgrade costs, careful planning is required for their use. This article will comprehensively explain the core information of Hint Books to help you efficiently utilize this scarce resource.

 

What Are Hint Books

Hint Books are items used to upgrade the hint levels of UMAs’ inherent skills i, divided into two categories: green and gold. Green Hint Books correspond to the upgrade of white skills, while golds are exclusively for strengthening gold skills. Both types of skills can be upgraded to a maximum hint level of 3. Upgrading can greatly increase the skill activation probability and effect intensity, but the process requires a large number of corresponding Hint Books and a substantial amount of in-game gold. They serve as an important “gold sink” in the late game—upgrading a gold skill to full level may even cost over 800,000 gold + 120 gold Hint Books.

 

Acquisition Channels

Hint Books are relatively difficult to obtain, with current main channels concentrated in the following two categories, and the overall supply is limited:

• Shop Purchase: A small number of Hint Books are regularly available in the “Upgrade Items” section of the Friendship Shop, including 4 of one green Skill Book, 2 of another green Skill Book, 2 of one gold Skill Book, and 1 of another gold Skill Book. It is recommended to purchase all available stock after each refresh to avoid resource waste.
• Event Rewards: Referring to the subsequent update rhythm of the Japanese server, Hint Books will be gradually integrated into the high-point reward system of major events. For example, in Japanese server events, 4 green Hint Books can be exchanged at 32,000 points, 3 of another green Skill Book at 52,000 points, and gold Hint Books will be unlocked at high-point thresholds. However, the output per event is only sufficient for partial upgrades, making it difficult to fully max out a single skill at once.
• Future Expectations: In addition to existing channels, Hint Books are likely to be supplemented in other regular shops such as the Friend Point Shop in the future. It is necessary to continuously pay attention to shop update dynamics.

 

How to Use Hint Books

The core principle for using Hint Books is “upgrade on demand and avoid waste”. Specific operations and precautions are as follows:

• Match Corresponding Items: Strictly select Hint Books according to skill types—white skills can only use green Hint Books, and gold skills must use gold Hint Books; cross-category use is not allowed.
• Control Upgrade Rhythm: Due to the scarcity of items and high upgrade costs, it is not recommended to use them too early. In the early stage, prioritize hoarding resources. Only after confirming the UMAs and core skills you will use for a long time, focus on investment and upgrading to avoid resource waste caused by frequent changes in training targets.
• Combine with Support Card Matching: Before upgrading, check whether the target skill has a support card with a high hint level available. If a skill (such as Professor of Curvature) can obtain Level 3 hints through mainstream support cards, there is no need to additionally consume Hint Books to upgrade the same skill inherent in the UMA, avoiding duplicate investment.
• Pay Attention to Gold Reserves: Upgrading gold skills requires a huge amount of gold, with full-level upgrades costing over 800,000 gold. Only start upgrading gold skills when gold reserves are sufficient (after completing UMA potential training and support card enhancement) to avoid affecting other training progress due to gold shortages.

 

Which UMAs to Prioritize Investing In

When selecting investment targets, comprehensive judgment should be made based on UMA usage rate, skill versatility, and support card adaptability. The priority ranking is as follows:

• Core Main UMAs: UMAs that serve as main combatants for a long time are the top choice, especially the “oshi” you personally prefer and plan to train for a long time. Strengthening their skills can directly improve core combat power.
• UMAs with Skills Unmatched by Support Cards: Prioritize UMAs with inherent skills that “no support card can provide hints for”. For example, Symboli Rudolph’s Dominator skill—since no support card can provide hints for this skill, it can only be upgraded through Hint Books, resulting in significant enhancement benefits.
• Versatile UMAs: Prioritize cultivating all-round UMAs suitable for various tracks and distances. After their skills are strengthened, they can cover more race scenarios, avoiding the idleness of enhancement benefits due to race type restrictions.
• Avoid Short-Term Strong UMAs: Be cautious of UMAs that are only strong in the current version and may be eliminated by version iterations in the future. Hint Books are long-term investment resources, so focus on core UMAs that can be used across versions.

 

Additional Practical Suggestions

Adhere to the Hoarding Principle: In the early stage of resource scarcity, it is recommended to hoard all obtained Hint Books. Only after clarifying the meta trend in subsequent versions and having a stable main lineup, concentrate on using them.

Focus on High Event Points: In future events, Hint Books are mostly hidden in high-point reward tiers. If the goal is to collect gold Hint Books, it is necessary to plan physical strength and training strategies in advance to challenge high-point thresholds.

Refer to Meta Resources: Use meta lists of support cards compiled by the official or community to query the adaptability of support cards for each skill, avoiding wasting Hint Books on skills that already have support cards with high hint levels.

 

Conclusion

Hint Books are valuable late-game resources in Uma Musume, requiring strategic hoarding, targeted acquisition via shops and events, and focused investment in versatile, long-term core UMAs or skills without support card alternatives. Use them sparingly to maximize combat power gains.
