Most pets are purely cosmetic, but some of the Old-gen console and 3DS -exclusive pets can do minimal damage to enemies. A pet will follow the player until they die, summon a different pet, leave the world or cancel the associated buff. When summoned, they will give the player a buff with the same name as the pet. They are completely invincible and have no set duration. Pets are creatures that follow the player around. Not to be confused with Town pets, the animal NPCs obtainable via the Zoologist.
