What Is the Logbook System?

The Logbook is a collection-based reward system introduced in the Secrets of the Silver Kingdom update (v5.0) that’s directly tied to Beast-Yeast story episodes. Unlike traditional progression systems, the Logbook rewards players for thorough exploration and completion of content through four main collection categories: Monster Traces, Boss Clears, Memory Fragments, and Relic Fragments.

This revolutionary system addresses a common player complaint about resource scarcity by providing substantial free rewards that rival paid content. The Logbook essentially creates a bonus reward track that runs parallel to your regular story progression, meaning you’re earning valuable resources while playing content you’d complete anyway.

Essential Logbook Components Explained 2026

Monster Traces: The Foundation

Monster Traces are the most common Logbook entries, requiring players to defeat specific monsters multiple times to collect their “traces.” Each monster requires exactly 40 traces to complete its Logbook entry, making this the most time-intensive but also most rewarding component.

Drop Rates by Difficulty:

• Story Mode: 1 Trace per clear
• Normal Mode: 2 Traces per clear
• Hard Mode: 3 Traces per clear

Pro Strategy: Focus on Hard Mode farming whenever possible. While it requires 14 runs per monster (compared to 40 in Story Mode), the time investment is significantly lower and you’ll earn additional rewards from the higher difficulty content.

Boss Clears: Fastest Crystal Source

Boss entries are the quickest way to earn Crystals through the Logbook system. Each boss only requires 5 clears to complete, with each completed boss entry rewarding 200 Crystals immediately.

Clear Requirements by Difficulty:

• Hard Mode: 2 clears needed
• Normal Mode: 3 clears needed
• Story Mode: 5 clears needed

Expert Tip: Prioritize boss entries first when starting a new episode’s Logbook. The 200 Crystal reward per boss makes this the most time-efficient method for building your Crystal reserves early in your Logbook journey.

Memory Fragments: Hidden Treasures

Memory Fragments appear as glowing yellow circles scattered throughout Beast-Yeast episode maps. These hidden collectibles are easy to miss but provide valuable rewards including coins and Logbook progress.

How to Find Memory Fragments:

1. Enter each episode map in exploration mode
2. Carefully scan for glowing yellow spots on the ground
3. Tap these spots to collect Memory Fragments
4. Each episode typically contains 3-5 fragments

Advanced Strategy: Create a systematic pattern for exploring each map, working from left to right and top to bottom. Many players miss fragments by rushing through maps or focusing only on stage completion.

Relic Fragments: The RNG Challenge

Relic Fragments are the most challenging Logbook component due to their completely random drop nature. These fragments can drop from any stage in Beast-Yeast episodes, with drop rates increasing significantly on higher difficulties.

Farming Strategy:

• Focus on Monster Madness daily runs
• Prioritize stages you need for other resources
• Accept that this component takes time to complete
• Don’t waste stamina specifically farming for Relic Fragments

Step-by-Step Logbook Completion Strategy

Phase 1: Boss Rush (Days 1-3)

Your immediate priority should be clearing all boss entries in available episodes. This phase provides the fastest return on your stamina investment:

1. Identify all bosses in currently unlocked episodes
2. Clear each boss on the highest difficulty you can comfortably complete
3. Collect your 200 Crystal rewards immediately
4. Track which bosses you’ve completed to avoid duplicate runs

Expected Rewards: 1,000-2,000 Crystals per episode depending on boss count

Phase 2: Monster Trace Farming (Days 4-14)

With boss entries complete, focus on Monster Traces systematically:

1. Create a spreadsheet or tracking document for each monster
2. Farm monsters on the highest difficulty you can clear consistently
3. Prioritize monsters that also drop resources you need for account progression
4. Stop farming each monster immediately after reaching 40 traces

Efficiency Tip: Use auto-battle for repetitive farming, but manually check your progress every 5-10 runs to avoid wasting stamina after completion.

Phase 3: Memory Fragment Collection (Ongoing)

Integrate Memory Fragment collection into your regular gameplay:

1. After completing stages, spend 2-3 minutes scanning each map
2. Take screenshots of maps to mark fragment locations for future reference
3. Return to completed episodes periodically to check for newly accessible fragments

Pro Strategy: Some Memory Fragments are only accessible after completing certain story requirements or unlocking new abilities.

Phase 4: Passive Relic Fragment Accumulation (Long-term)

Relic Fragments should be your lowest priority due to their RNG nature:

1. Include Relic Fragment stages in your daily Monster Madness runs
2. Don’t specifically farm for Relic Fragments unless you’re very close to completion
3. Accept that this component may take weeks or months to complete naturally

Advanced Logbook Optimization Techniques

Stamina Management Excellence

Efficient stamina usage is crucial for maximizing Logbook rewards:

Daily Routine:

• Morning: Complete Monster Madness runs (highest Relic Fragment chance)
• Afternoon: Focus on Monster Trace farming for current priority monsters
• Evening: Boss clears on remaining stamina (if any incomplete bosses)

Stamina Optimization:

• Always use the highest difficulty you can clear without excessive team building
• Time Jumper usage should prioritize stages that give multiple Logbook benefits
• Consider stamina cost vs. reward ratio when choosing farming locations

Team Composition for Logbook Farming

Different Logbook components require different team approaches:

Boss Clear Teams:

• High burst damage for quick clears
• Survival is less important than speed
• Consider using your strongest main team

Monster Trace Farming Teams:

• Sustainable damage output
• Good survival for extended farming sessions
• Include resource farming bonus characters when possible

Memory Fragment Collection Teams:

• Any team works for exploration
• Consider bringing characters with movement abilities for easier navigation

Resource Synergy Strategies

Maximize your efficiency by combining Logbook progress with other account needs:

Multi-purpose Farming:

• Choose Monster Trace stages that also drop materials you need
• Combine boss clears with daily quest requirements
• Use Logbook farming as opportunities to test new team compositions

Long-term Planning:

• Save Time Jumpers for stages with multiple Logbook benefits
• Plan your Beast-Yeast progression around Logbook completion
• Consider future episode releases when allocating resources

Episode-Specific Logbook Tips

Episodes 1-2: Faerie Kingdom

Early Game Focus:

• Boss entries provide the best Crystal return for new players
• Monster difficulty is relatively low, making Hard Mode accessible
• Memory Fragments are easier to spot in simpler map layouts

Special Considerations:

• These episodes have the lowest stamina costs
• Ideal for learning Logbook mechanics
• Good for establishing farming routines

Episodes 3-6: Beast Introductions

Mid-Game Challenges:

• Increased difficulty may require team adjustments
• More complex Memory Fragment locations
• Higher Relic Fragment drop rates compensate for increased difficulty

Strategic Adjustments:

• Consider Normal Mode farming if Hard Mode proves too difficult
• Focus on one episode at a time for better progress tracking
• Save Time Jumpers for the most difficult stages

Episodes 7-10: Advanced Content

End-Game Optimization:

• Full Hard Mode completion should be achievable
• Complex Memory Fragment patterns require systematic exploration
• Maximum Relic Fragment drop rates

Expert Strategies:

• Use Challenge Mode modifiers for additional Crystal rewards
• Integrate Logbook farming with other end-game content
• Consider resource costs vs. benefits for each farming session

Common Logbook Mistakes to Avoid

Resource Management Errors

Over-farming Completed Entries: Many players waste stamina by continuing to farm monsters after completing their 40-trace requirement. Always track your progress carefully and stop immediately upon completion.

Inefficient Difficulty Selection: Don’t automatically assume Hard Mode is always best. If Hard Mode requires 3-4 times as much time as Normal Mode for only 50% more traces, Normal Mode may be more efficient for your specific situation.

Poor Memory Fragment Strategy: Rushing through maps without scanning for Memory Fragments costs you significant rewards over time. Always spend 2-3 minutes per map checking for fragments before moving on.

Planning Mistakes

Ignoring Account Synergy: Don’t farm Logbook entries in isolation. Consider what other resources you need and choose farming locations that provide multiple benefits.

Burnout Prevention: Logbook completion is a marathon, not a sprint. Set realistic daily goals and don’t feel pressured to complete everything immediately.

Team Building Missteps: Don’t sacrifice your main progression teams for specialized Logbook farming teams unless absolutely necessary. Most Logbook content can be completed with your regular teams.

Frequently Asked Questions

How long does it take to complete a full Logbook?

Complete Logbook completion typically takes 2-3 months for active players, but this varies significantly based on your daily play time and team strength. Boss entries can be completed in a few days, while Relic Fragments may take the entire duration due to their RNG nature.

Is the Logbook worth the stamina investment?

Absolutely. The Logbook provides some of the best free-to-play value in the game, with thousands of Crystals and valuable resources. Even if you only complete 50% of each Logbook, you’ll still earn significant rewards that would otherwise cost real money.

Should I wait for more episodes before starting?

No, start immediately. The Logbook is designed to be completed as you progress through the game, and waiting only delays your access to valuable resources. Early episodes also serve as excellent practice for learning Logbook mechanics.

Can I complete Logbook entries in co-op mode?

No, Logbook progress only counts in solo play. However, you can use co-op mode to practice difficult stages before attempting them solo for Logbook credit.

Do Logbook rewards expire?

No, Logbook rewards do not expire. Once you unlock an episode’s Logbook, you can take as long as needed to complete it. However, rewards are only granted once per entry, so there’s no benefit to re-completing entries.

Should I use Time Jumpers on Logbook stages?

Yes, Time Jumpers are highly recommended for Logbook farming, especially for Monster Trace stages. They allow you to maximize your stamina efficiency and complete Logbook entries much faster.
