Bestiary

**PC/Console/Mobile/tModLoader-Only Content**: This information applies *only* to the **PC**, **Console**, **Mobile**, and **tModLoader** versions of *Terraria*.
For a guide to completing the Bestiary, see Guide:Completing the Bestiary.

The **Bestiary** is an in-game catalog of *Terraria's* various entities, including enemies, NPCs, critters, and bosses. It can be viewed by  opening the inventory and pressing `⚒ Use / Attack` on the  book icon located to the right of the item trash can, at the bottom right of the inventory, or  opening the settings and tapping the Bestiary icon. The Bestiary displays a description and basic statistics for each entity, including health, damage, defense, and knockback resistance, as well as advanced information like item drop rates. Entries can be sorted and filtered by various criteria, like stats, locations, times, events, etc.

The 0-5 Star system in the top left corner reflect the rarity of a given creature.

Initially, no information is available about any particular entity. There are four stages of progression for each entity, each unlocked based on a player's current experience level with that entity in the world:

* 1 kill: Name and portrait display
* 10 kills: Stats and description display
* 25 kills: Item drop lists display
* 50 kills: Item drop rates display

Progression is tracked by various methods, depending on the entity type:

* For an enemy, kills of that enemy are counted (kills made before the 1.4.0.1 update will not count). Enemies with multiple variants (such as Zombies) have a separate tracker for each variant (50 Pincushion Zombie kills, 50 Slimed Zombie kills, etc.).
* For a boss, only one kill is required to display all information.
* For a critter, the counter advances based on how many of that critter type the player came into proximity with.
* For a town NPC, the number of times the player opened the dialogue window of that NPC is counted.

At the bottom of the Bestiary is a bar that fills as the Bestiary is completed, allowing players to track their progress. Bestiary progress is tied to a world, not a character. Unlocking 10% of the entities in the Bestiary (54 entries) makes the Zoologist NPC available, who sells progressively more items (e.g. the Cat License) as the player completes more of the Bestiary. Unlocking all information for the entries is not a requirement for this, as long as the entries themselves have been unlocked.

There are 540 Bestiary entries in total.

If the player unlocks 100% of the Bestiary, the Zoologist will sell the Universal Pylon

## Filters

From top-left to bottom-right in the Bestiary display. The "Number of creatures" column may show double-counted creatures that appear in multiple biomes.

## Excluded and unachievable entities

Certain enemies do not have Bestiary entries at all:

* Pirate's Curse
* Spiked Slime, due to there not being a way to have it spawn in Classic worlds
* Golden Slime, due to there not being a way to have it spawn in any World Seed except for Celebrationmk10
* Jungle Mimic, due to there not being a way to have it spawn in any World Seed except for Celebrationmk10

Certain enemies in the game do not have distinct Bestiary entries for their variants:

* Mimic
	+ Chest
	+ Gold Chest
	+ Shadow Chest
* Butterfly
	+ Monarch Butterfly
	+ Sulphur Butterfly
	+ Zebra Swallowtail Butterfly
	+ Ulysses Butterfly
	+ Julia Butterfly
	+ Red Admiral Butterfly
	+ Purple Emperor Butterfly
	+ Tree Nymph Butterfly
* Zombie
	+ Armed Zombie
	+ Armed Pincushion Zombie
	+ Armed Slimed Zombie
	+ Armed Swamp Zombie
	+ Armed Twiggy Zombie
	+ Armed Female Zombie
	+ Armed Torch Zombie
* Skeleton
	+ Bone Throwing Skeleton
	+ Bone Throwing Headache Skeleton
	+ Bone Throwing Misassembled Skeleton
	+ Bone Throwing Pantless Skeleton
* Size variants are also not given unique entries, likely due to how widespread they are and their potential to bloat the bestiary far beyond any reasonable comprehensiveness benefit.

Fish (specifically those obtained as items via fishing, as opposed to fish critters and monsters such as the goldfish and Arapaima) do not have Bestiary entries, despite being living creatures.

Pets, mounts and minions which one may expect to have dedicated entries do not have them either.

Some enemies with entries cannot be obtained at all in given worlds, blocking the completion of the Bestiary:

* Spider Cave-related entities (Wall Creepers, Black Recluses, and the Stylist) in Not the bees worlds
* Certain NPCs (Golfer & Princess) in worlds made before 1.3

## Notes

* The Bestiary is linked to the world. If a fully unlocked character is brought to a new world, the Bestiary will be empty for them in that world.
	+ An exception is The Torch God, which will be unlocked immediately if the Torch God's Favor has been used by the character.
* The Bestiary uses a separate kill counter from the one used by the Tally Counter; this is evident due to the fact that worlds created before 1.4 require killing each creature all over again in order to fill out the entries.
* Three enemies are somewhat exclusive: Crawdad, Giant Shelly, and Salamander. In a given world, there can be only two of them, chosen randomly; the third will not appear. This is taken into account by the Bestiary progression logic, and the missing enemy will register as unlocked when the other two exclusive creatures are unlocked.
* in For The Worthy, It is still possible to acquire normal Bunny *item* if the player catches a Bunny with a party hat (that spawns during the Party event), Bunny in a Santa costume (that spawns during Christmas) or a Bunny in a Slime costume (that spawns during Halloween) variant. Note that all of these variants have a separate Bestiary entry and do not count as regular Bunnies, and obtaining the item does not unlock the Bestiary entry.
* Old One's Army enemies always show sprites and stats of their Tier 3 variant.
* Encountering any golden critter will automatically unlock every other golden critters' entries, meaning that it is only necessary to come into proximity with one type of golden critter.
* Killing enemies spawned from statues does increase their respective progression levels, the same for encountering statue-spawned critters.

## Tips

* Enemy spawning statues can be used to fill out information on less common enemies, like the Medusa or Mimics.
	+ If the Pigron statue is obtained, then there is no need to create a Corrupt/Crimson/Hallowed Ice biome, since the statue can spawn all three variations, and the Pigron is the only unique enemy found in those respective sub-biomes.
* The entries for the Dungeon Guardian and Tortured Soul can be obtained by talking to the Clothier and Tax Collector, respectively.
* In order to reach 100% Bestiary completion, a player-made Corruption or Crimson biome must be made, depending on which one the world already has. This includes a variant of the Surface, Underground, Desert, Underground Desert, Snow, and Ice biomes to collect all Crimson/Corruption variants of enemies and critters.
	+ The Dryad, when spoken to in a Graveyard during Hardmode, sells seeds of the opposite evil biome.
	+ Drunk worlds include both evil biomes.

Furthermore, it is necessary to trigger the seasonal events Halloween and Christmas to unlock Santa Claus and all variants of enemies and critters.
* Reaching the final waves of the Pumpkin and Frost Moons triggers a single ingame day of Halloween/Christmas.
* Changing the device's date allows skipping the time that would have to be waited otherwise. See the events' pages for details.

* Enemies that do not have exclusive drops or do not even drop coins (such as the Gnome) only need to be killed 10 times to unlock all possible information.
* The search function of the Bestiary allows several aliases for certain bosses:

## Trivia

* The maximum Bestiary completion percentage that can be obtained in a pre-Hardmode world (including bringing items over from a Hardmode world) is 62.04%, or 335 entries.
	+ Without bringing items over from a Hardmode world, the maximum completion percentage is 49.81%, or 269 entries.
* Icons exist inside *Terraria's* game files for an additional 5 filters, which go unused:
	+ ​ Oasis
	+ ​ Blizzard
	+ ​ Slime Rain
	+ ​ Hardmode
	+ ​ "Item Spawn"
* Gnomes are the first enemy listed in the Bestiary. They are the only enemy in the game whose Bestiary entry can be unlocked without killing it.
* It is possible to complete 15% of the Bestiary without killing any enemies at all.
* The Moon Lord has the only Bestiary entry without a background or biome, likely due to its out-of-this-world nature. The background on its portrait is completely black and empty, and the void-filter is not seen.
* There is an unused bestiary entry for the cultist clone, which is:

"Though it is an illusion designed to distract from the true threat, this fake cultist can still use some basic offensive magic as well."
