Bestiary

The Bestiary is an in-game, filterable encyclopedia that shows information about enemies, critters, bosses, and NPCs. It includes basic statistics like health, damage, defense and knockback, but also advanced information like item drop rates. Furthermore, it displays a short description of the entity similar to item tooltips. Entries can be sorted by different statistics and can be filtered by certain locations, times, events, and other categories.

Initially, no information is available about any entity. When an enemy is killed (or a town NPC talked to), more information is revealed. At the bottom of the Bestiary is a bar that fills as the Bestiary is completed, allowing players to track their completion progress.

The Bestiary is tied to a world, not a character.

Filling in your Bestiary allows you to unlock the Zoologist NPC, and one of her sold items.
