- Abyssus logbook serves as the central hub for tracking your in-game stats, run history, and challenge progression.
- Unlocking Scribe is a prerequisite for the New Monarch achievement, requiring you to collect all blessings and charms.
- Expedition metrics store highly detailed run data, including accuracy, damage output, and your primary causes of death.
- Targeting challenges systematically allows you to unlock powerful weapon mods and valuable Soul Fragments.
What is the Abyssus Logbook?
The Abyssus logbook is an essential interactable object located at the entrance to the Artefact Room [web]. It can also be accessed directly through the main game menu [web]. This tool is designed to act as your ultimate progression tracker, monitoring everything from your overall career statistics to your current challenge completion rate [web]. Understanding how to read and utilize this data is key to optimizing your builds and planning your future runs.
Video Highlights:
- Unlocking the Scribe achievement is mandatory for obtaining the New Monarch status [youtube].
- Charms only need to be picked up once during a run to register in your logbook [youtube].
- To register blessings, you must equip them across all three slots and complete a run [youtube].
By interacting with the logbook, you can view your unlocked relics, check which challenges are closest to completion, and analyze your performance trends over time [web]. This makes it an invaluable asset for players looking to transition from casual runs to high-level Deep Water expeditions.
Always check the logbook between runs. It helps you identify which specific weapons or abilities you need to use next to unlock missing mods or complete pending challenges.
Unlocking the Scribe Achievement
Unlocking the Scribe achievement is one of the most common points of confusion for players aiming for 100% completion in Abyssus [youtube]. The game states that you must unlock the logbook entries for all blessings and charms [youtube]. However, it does not explicitly explain the mechanics required to register these items permanently.
To complete this monumental task, you must follow a specific sequence of actions for both relics and blessings.
Identify Missing Charms
Navigate to the Relics section in your menu and select Charms [youtube]. Identify which charms are currently locked. Most of these are tied to straightforward challenges, such as accumulating 1,000 Gold or dealing specific damage types [youtube, web].
Pick Up and Register Charms
Once a charm is unlocked, you must find and pick it up during an active expedition [youtube]. You do not need to finish the run with the charm equipped; simply picking it up and immediately dropping it is enough to register it in your logbook [youtube].
Register All Blessings
For blessings, you must equip the specific blessing type on your primary weapon, secondary weapon, and active ability [youtube]. You must then complete at least one full run while picking up every variation within that blessing's upgrade rows [youtube].
| Relic Type | Registration Requirement | Key Tip for Fast Unlock |
|---|---|---|
| Charms | Pick up once in an expedition [youtube] | Drop the charm immediately after picking it up to save slot space [youtube] |
| Blessings | Equip on primary, secondary, and ability [youtube] | Complete a full run and collect all upgrade rows for that blessing [youtube] |
By systematically working through your locked charms and equipping the necessary blessings, you will satisfy the requirements for the Scribe achievement, clearing the path toward unlocking the New Monarch title [youtube].
If you manually leave an expedition before successfully completing it or dying, the run data and any newly found relics will not be written to your logbook [web].
Abyssus Logbook Challenge List
The core of the Abyssus logbook revolves around its extensive challenge list [web]. These achievements act as milestones that reward you with Soul Fragments, unique weapons, or powerful forge mods [web]. There are 94 challenges in total, culminating in "The New Monarch" achievement [web].

Tracking Stats and Expedition History
Beyond tracking achievements, the Abyssus logbook serves as a deep analytical tool [web]. It is divided into several sub-sections that allow you to monitor your career performance and identify areas of your gameplay that require improvement [web].
Expedition History
The Expeditions section keeps a rolling log of your completed or failed runs [web]. This section is incredibly detailed, tracking variables such as:
- Total damage dealt and taken during the run [web]
- Overall accuracy and Weakspot accuracy percentages [web]
- The exact enemy that dealt the killing blow [web]
- Equipped weapons, active blessings, and applied forge mods [web]
Career Player Statistics
The Player Stats sub-section aggregates your data across all expeditions to compile your lifetime profile [web].
| Metric Category | Specific Data Tracked | Practical Application |
|---|---|---|
| Expedition Stats | Success rate, win streaks, and average clear times [web] | Helps measure your consistency and speedrunning progress [web] |
| Player Stats | Favorite blessing, total times downed, and total deaths [web] | Identifies your preferred playstyles and survival bottlenecks [web] |
| Enemy Stats | Total kills per enemy type and death counts per enemy [web] | Pinpoints which enemy types pose the greatest threat to you [web] |
By analyzing these statistics, you can determine if your accuracy is lagging, which weapons yield your highest damage outputs, and which enemies serve as your personal "nemesis" [web].
The game tracks your "nemesis" (the specific enemy type that has killed you the most) [web]. Use this data to adjust your target prioritization during chaotic combat encounters.
Best Strategies for Fast Challenge Completion
Completing all 94 challenges in the Abyssus logbook requires a structured approach [web]. Trying to complete everything at once can lead to inefficient runs and unnecessary deaths. Instead, segment your progression into dedicated runs.
Efficiency Runs
Combine passive challenges. For example, run a high-health build using the Healthy Commitment reward to simultaneously work toward Thick-Skinned and Meat Shield [web].
Weapon Mod Farming
Dedicate runs solely to unlocking all primary and secondary mods for a single weapon, such as the Shotgun or Tesla Gun, to complete the Connoisseur challenges [web].
Deep Water Progression
Gradually increase your Deep Water levels. Completing level 20 unlocks the Baseballer and completes the ultimate difficulty challenges [web].
To maintain steady progress toward 100% completion, keep a checklist of essential milestones active during your play sessions.
Essential Logbook Milestones:
- Destroy all Surge Fissures across all five major zones [web]
- Unlock all 11 unique weapons and abilities [web]
- Complete an expedition with every weapon type to earn the Bender reward [web]
- Register every blessing variation to unlock the Scribe achievement [youtube, web]
For weapon-specific kill challenges, play on lower Deep Water levels. This allows you to gather large groups of weaker enemies, making multi-kill achievements much easier to obtain.
