Pets

Pets are little critters that follow you around. Like summoned minions, pets are completely invincible and they have no set duration - they will follow you until you die, summon a different pet, or cancel the associated buff. Most are purely cosmetic, but some of the console-exclusive pets can do minimal damage to enemies. They can also fly if you go to high for them to jump up.
