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 your inventory and clicking the book icon located to the right of your item trash can. The Bestiary displays a description and basic statistics for each entity, including health, damage, defense, and knockback, as well as advanced information like item drop rates. Entries can be sorted and filtered by various criteria, like stats, locations, times, events, etc.

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

Experience 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 Arrow Zombie kills, 50 Gel Zombie kills, etc.).
 * For a boss, just 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 close proximity with.
 * For a Town NPC, the number of times the player chatted with 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 makes the Zoologist NPC available, who sells progressively more items (eg. 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.
