Pets

Pets are used in battle and will fill in for the player just in case they lose hearts or wish to switch for potential elemental benefits in combat. Players may have at most 2 pets in battle. They can level up after winning a battle.

The evolution of a pet used to affect stats, but in a recent update, pets are now all equal in stat growth, so evolution only affects appearance (except for Embershed). A player that is not a member can only have 10 pets in their collection, but a member can have more than 100 simultaneously, and the stronger a player's pet(s) are, the stronger their opponents are in PvE battles; these pets will not be rendered unusable by loss of a membership. Level and strength of enemies is not affected in PvP, however. If a player in Harmony Island performs a Rune Run or combat Crystal Caverns, they cannot switch their team or rescue new pets except for Shivertusk in the case of Crystal Caverns.

List of Pets
There are currently 155 pets in Prodigy, including the leaked pet, Lumibolt.

Collection and Pet Book
The Collection and Pet Book, previously the Bestiary, is a feature that all players have. While the Collection provides access to a player's individual pets and current combative team hotbar, the Pet Book gives access to pet flavour text (in-game descriptions) and a species' power-to-hearts ratio. If a player has never encountered a certain pet, that species' Pet Book slot will show just a question mark with a black background. If a player has seen a certain pet without ever possessing one, the pet book will display the pet greyed out.

How To Access
The Pet Book can be accessed via the overworld hotbar at the bottom of the screen. Interacting with the square that contains a paw print will open the Collection and Pet Book.

History
Previous Pet Books looked like 2 boxes: one for a player's pet team and one for their current entire collection. Each box shows a player's pet icons along with a wizard icon. Interacting with a pet's icon will let a player choose to see its stats, flavor text, or set it free.

The current Pet Book is divide into 2 columns: one showing a player's pet team (shows a wizard and pet's body) and another showing a player's pet index (only shows pets' respective icons.) A player can see how many stars and hearts a pet has, but they can still click on it and see its spell(s) and element. Clicking on the pet's icon will let them add it to their combat team or release the pet (Epics are irreleasible). Collections have always been private so that a player cannot see another's collection without external recordings available.
