Mob Journal
by KevzCz
With Mob Journal, players who encounter mobs in a world have each one recorded automatically in an in-game book, along with its details and drops.
What it does
Mob Journal records every mob a player has encountered in the world and keeps those entries in a journal item. Opening the journal, by default with the J key, shows a double-page book where players browse the discovered mobs. Mobs a player has not met yet stay out of the book, and each new discovery can trigger a notification.
The journal is a client and server mod, so the server and every player need it. Installation requires nothing beyond the loader itself, and the mod is published for Fabric, Forge and NeoForge in two game versions, 1.20.1 and 1.21.1, under the MIT License. The source code is open source, with a public issue tracker and wiki.
Key features
Automatic discovery
Each mob a player meets is added to the journal without any command or manual step.
Mob details
Entries show health, armor, drop previews and kill and death statistics for each discovered mob.
Search and filters
Mobs can be searched by name and sorted with filters, so large collections stay simple to browse.
Custom descriptions
Authors can write their own mob descriptions in JSON files, with simple Markdown, icons and loot placeholders.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Modded mob packs
Pack makers who add many mobs can document each one in the journal without writing a separate guide.
Survival progression
Players can track which creatures they have already fought and return to the book to check their drops.
Who it’s for: Players who want a record of the mobs they meet, and pack authors who want to add written descriptions for the mobs they include.
