The second new companion brings several new concepts to what a small pet can be. The Ethereal Soul-Trader is a nearly life-size traveling buddy who doubles as a specialized vendor, allowing its owner to purchase neat cosmetic items. One such item even allows you to change your other small pets into ravenous Flesh Beasts.
The third new pet follows the trend of "life-sizing" companions. This one is a Coyote Spirit which, oddly enough, is summoned by a hat, much like our old Bloodsail Parrot. Earning this pet will require doing a new quest in Old Hillsbrad on heroic.
