Pets

Pets are little critters that follow you around. They are completely invincible and have no set duration: They will follow you until you die, summon a different pet, or cancel the associated buff.

Most Pets are purely cosmetic, but some of the console-exclusive Pets can do minimal damage to enemies. Summoned Minions operate similarly, but are primarily intended to aid combat rather than being cosmetic. They seem to count as town NPCs, since whenever you have a pet, enemy spawn rates decrease.

In total, there are 37 pets: 22 on PC, 25 on console, 33 on mobile.
