Biology Dictionary

Discover, highlight, inspect, modify - your vanilla & modded mob encyclopedia

Sound familiar?

One screen for all of those problems.

Gameplay Preview

• No new blocks or entities. The book is implemented with NBT and stays vanilla-friendly.
• Works with vanilla and modded mobs.

Open the Dictionary

Biology Dictionary	Discovery Progress
Vanilla mobs, modded mobs, all in one book.	Build your encyclopedia one discovery at a time.

• Full mob catalog — Vanilla and modded mobs are collected automatically, no setup required.
• Discovery progress — Track which mobs you have found and which ones are still waiting.
• Multiple discovery rules — Use a simple "all unlocked" mode, vanilla kill statistics, or Biology Dictionary's own discovery system.
• Configurable discovery actions — Detail screens, telescope observation, interaction, kills, and more can count as discovery.
• Discovery records — Biology Dictionary mode can record how, when, and where you first met a mob.
• Configurable module behavior — By default, undiscovered mobs hide their details; you can also make discovery a pure collection layer.
• Entity highlight — Highlight nearby mobs of the same type, with different ranges and costs.

Telescope Discovery	Entity Highlight
A telescope sighting can count as a real discovery.	Highlight nearby mobs when rare targets are hard to spot.

Open a Mob Page

Entity Details	Entity Tags
Inspect properties, use skills, and change behavior.	Classify mobs from several angles for faster lookup.

• Overview / detail pages — Overview pages show default or reference data; detail pages show the live state of the entity you are looking at.
• Base stats — Health, air, effects, speed, jump strength, hitbox, and whether the mob counts toward spawn caps.
• Ecology — Habitat, loot table, edible items, tempting items, and leashability.
• Variants — Standard variants, horse markings, panda genes, villager types, and more.
• Behavior state — AI, invulnerability, silence, persistence, portal cooldown, growth, breeding cooldown, and love status.
• Special mob data — Villager schedules, restocks, job sites, bee hives, dolphin moisture, screaming goats, pet owners, wandering trader despawn timers.
• Entity skills — Lock growth, block breeding, control portals, disable AI, force persistence, mute, force restock, retain traders, gift pets, get spawn eggs, and more.
• Skill costs — Skills require XP, items, permissions, or Creative mode by default; costs can be configured.

The tag page supports several views: built-in groups, MC tags, mod namespaces, and Java class/interface categories.

Special Screens

• Inventory access — View, take from, or fill supported mob inventories. In Survival, this is stealing, so stay out of the target's sight.
• Beehive info — Open a dedicated beehive or bee nest screen to inspect honey level, bee count, and bees inside.

Inventory Access	Beehive Info
Steal or fill inventories so villagers stop picking up wheat.	Use the dictionary on a hive to check bees and honey.

Controls

Biology Dictionary is built around screens. Open it by:

1. Right-clicking while holding the Biology Dictionary book
2. Pressing the hotkey (default `); Survival needs the book unless configured otherwise, while Creative can always open it

The screen depends on what you are looking at.

Obtaining

How to get the Biology Dictionary book:

1. In Creative mode, or when Survival hotkey access is enabled, the physical book is optional.
2. The book is just minecraft:writable_book + NBT. No custom item is added.

Wandering Trader	Creative Inventory
In Survival, buy the Biology Dictionary from Wandering Traders.	In Creative, find it at the end of Tools & Utilities.

Survival

Buy from Wandering Traders. Sell chance starts at 100% and gradually drops to 20% over time, without taking up any vanilla trade slots.

Easy to find early when you're broke, impossible to find later when you're rich (cue evil laugh)~

Kidding — it takes about 2 real-time days (144 in-game days) to hit 20%. You'll be fine.

Pack authors can disable trader sales in the config and add their own recipes instead.

Creative

Find the Biology Dictionary book at the end of the Tools & Utilities tab.

Mod & Datapack Support

• Custom Entity Descriptions — Add or override mob descriptions via resource pack (docs)
• Custom Spawn Descriptions — Manually adjust spawn biome and structure descriptions via datapack (docs)
