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.

You can also get "Elfa" on Android and iOS by cutting down trees.
