Basically the quest is bugged and you can get an unlimited amount of pets that have 30,000 hp each. They only do 250-300 dmg each, however if you had the balls to spawn a good hundred of these suckers, well, you'd have your own private army.
I don't wana get kicked off beta so I didn't take this to the extreme potential it has, however if you have an extra beta key and want to command your own army, I suggest giving this a whirl.
How do you do it? Simple. Use the item you got for the quest, then "eject" from it. Repeat every 30sec.
