Just learned about this, dont sleep on these little critters, every drakeling has the ability to store xp from the player, upto I believe 30k. If you then take that stored xp and give it to a creature, the creature not only gains a ton of levels but you will also receive a new item called the dragon hoard, you use it like a treasure map, and the more xp you give to a creature at once the better the hoard will be. Im talking about massive massive payout. I've gotten kibble from every dragon hoard so far as well. Definitely worth having on your shoulder while out and about just for that.

Quick tip, go hunting for alphas. They definitely give the most stored xp to the drakeling. !!!
