So what is the nature of heroic orbs? Do we get specific orbs of heroic dragons (like the current orbs) or do we collect 10 orbs and get a random heroic dragon? I highly doubt the second one because it's less of a money grabber but I'm still hyped.

The info on the latest heroic race is explained HERE. In the future please search before creating new topics, most times one already exists. This is the second topic you created today that already had explanations for your questions.
