Pets

Pets are creatures that follow the player around. They are completely invincible and have no set duration. When summoned, they will give the player a buff with the same name as the pet. A pet will follow the player until they die, summon a different pet, or cancel the associated buff. All pets are purely cosmetic. Pets do not count against the player's current minion limit.

The Calamity Mod currently adds 16 pets and 5 light pets into the game.

Light Pets
Light Pets are summoned secondary characters that float alongside players to provide a traveling light source. They incur no mana nor any other cost, and remain indefinitely until the player cancels the buff, summons a replacement light pet or dies. Only one light pet can be present at once.
